Sleep is a natural regularly occurring physiological function, where humans and other animals reduce physical and mental activity, lessen responsiveness to stimuli, and particular patterns of brain activity occur (Ettinger 2018). Prolonged lack of sleep or sleep deprivation can cause impaired memory formation as well as adverse effects on the brain’s other cognitive functions such as learning, language, reason, and perception. Sleep deprivation has also been linked to significant mental diseases, such as depression, psychosis, and bipolar disorder (Horowitz, 2020). Physical problems attributed to consistent lack of sleep include weakening of the immune system, headaches, heart disease, fainting, weight gain or weight loss, blurred vision, and hernias. Other related ailments may include obesity, cancer, stroke, asthma, high blood pressure, diabetes, arthritis, and kidney failure. Severe sleep deprivation in humans can also be fatal, where a rare neurological ailment called fatal familial insomnia, results in damage to areas of the thalamus (Horowitz, 2020).
Studies with REM-deprived sleep participants showed the effects of decreased ability to concentrate on tasks, increased irritability, hostility, anxiousness, and aggressiveness. Studies also showed that REM-starved participants entered into REM sleep almost as soon as they were permitted to nod off, over the course of a one-week experiment. Participants experienced a REM rebound effect, where they spent roughly 50 percent more time in REM than they did before the start of the experiment. This REM rebound effect seems to occur immediately after a duration of forced wakefulness during a night’s sleep. Physiological changes in animals have been observed in other studies regarding REM deprivation, with effects of weight loss, deteriorated appearance, skin lesions, increased energy expenditure, decreased body temperature, and even death. Researchers think that if humans experienced similar circumstances of sleep deprivation used in animal studies, similar outcomes would present (Ettinger 2018).
Studies show that sleep is necessary, but exactly why is not clear. Theories exist that we require sleep to conserve energy, avoid predation, and memory aid. However, none of these theories are widely accepted by psychologists. Another theory is that sleep helps in mental and physical restoration. Sleep is thought to restore resources that are drained during our daily activities. Studies show that people often sleep longer after particularly tiring events helps to support this theory. Unsettled evidence shows that specific types of tissue restoration might happen during sleep. Growth hormone is secreted at increased levels during Stage 4 sleep as well as brain neurotransmitters possibly being restored during sleep. Other research indicates that sleep is essential for brain homeostasis. Additionally, research suggests that metabolic waste that accumulates from neural activity is eliminated from the brain and cerebral spinal fluid, while only occurring during sleep (Ettinger 2018). This theory has merit, as other relative studies offer further evidence of sleep quality affecting health and well-being, specifically with intensive care unit (ICU) patients (Pisani, 2015). I find it hard to discredit this theory, just based on personal experience with almost everyone I have ever known or met, expressing how much more restored, refreshed, and energetic they are when they have regular quality sleep.
I feel that American culture in general, does not pay much attention to preventing disease and illness, let alone the specific issue of sleep deprivation. We have gradually grown into a nation where we live for our pleasures today, with little regard for the consequences that will come tomorrow. Many see modern allopathic medicine and its many pharmaceutical options, as the only path to fix all of our ills. There is a plethora of medications that we can take to keep us awake when we don’t get enough sleep. Conversely, we also have a wide variety of other pharmaceuticals to help us sleep when we are too awake, anxious, or stressed.
I see many college-aged kids, who are learning how to manage and navigate their college lives of studies and social life, while also trying to stay safe and healthy in the process. I don’t really think the issue of college student sleep deprivation has changed much over the last few decades, as far as young adults exercising their independence and learning of their limits. What has changed, I believe is the acceptance of legal as well as illegal drugs being used to manage the ups and downs of coping with the on-campus “college life”. Additionally, the last 2 years of dealing with the COVID-19 pandemic have greatly added to the recipe for potential psychological issues. Many people of all ages have experienced stress as they attempt to balance their relative circumstances. Many people were inside more which may have led to a more sedentary lifestyle, eating more poor-quality food, drinking more alcohol, consuming more recreation and medicinal drugs, and other issues that can affect the quality of sleep. Consequently, I think the more relative issue that is yet to unfold, is how has the management of the pandemic affected sleep quality across many demographics? This topic will probably take years to study in order to draw any logical conclusions.

I often reflect on how our breath, movement, and embodied practices unlock intelligence that’s deeper than thought alone. I’ve discovered that the vagus nerve, also known as cranial nerve X, is far more than a static anatomical cord. It is a sprawling, bidirectional highway connecting brain with body, from lungs and heart to gut and even immune activity (Huberman, 2025). About 85 % of its fibers are sensory (body to brain), while 15 % are motor (brain to body), making it a master regulator of heart rate, digestion, mood, learning, and immune responses (Huberman, 2025; Wikipedia, 2025).
The vagus nerve gets its name from the Latin word “vagus,” which means wandering. This is a fitting name because the vagus nerve has an unusually long and far-reaching path through the body. It originates in the medulla oblongata of the brainstem and “wanders” through the neck, thorax, and abdomen, innervating a wide array of organs, including the heart, lungs, stomach, intestines, and more (Wikipedia, 2025).
Its full name is often “nervus vagus”, emphasizing its meandering and expansive nature, unlike most cranial nerves, which are typically more localized to the head and neck. Because of this extensive distribution, the vagus plays a central role in regulating autonomic functions, such as heart rate, digestion, and respiratory rate, and serves as a vital communication link between the brain and the body’s internal environment.
One of the most empowering revelations for me was how intertwined vagal tone is with breathing. Specifically tailored breathwork of the physiological sigh (two inhales, followed by a long exhale) activates parasympathetic vagal fibers via the nucleus ambiguous, slowing heart rate and enhancing heart‑rate variability (HRV), a gold‑standard biomarker of autonomic balance (Huberman, 2025; Leggett, 2023).
Yet, the vagus nerve isn’t only a conduit for calm. I have found that physical movement,especially full‑body activation, triggers adrenal adrenaline, which then stimulates vagal sensory fibers. Those fibers feed into brainstem centers like the locus coeruleus and nucleus basalis, releasing norepinephrine and acetylcholine. The result is heightened focus, enhanced neuroplasticity, and a robust alertness without external stimulants (Huberman, 2025).
Nutrition plays a role too. Most serotonin resides in the gut; it doesn’t cross into the brain, but it influences mood via vagal pathways, sensing gut serotonin that signals the dorsal raphe nucleus which then boosts central serotonin (Huberman, 2025). So, adopting a tryptophan‐rich diet and nurturing one’s microbiome (e.g., low‑sugar fermented foods) can become part of one’s daily routine.
I have learned that simple practices like humming, gargling, or gentle neck stretches can become non‑drug tools to engage vagal branches in the throat and chest, mechanically activating fibers that foster parasympathetic tone (Tourino Collinsworth, 2025; Huberman, 2025). A simple low hum can reliably bring a drop in heart rate and stress.
One of the most profound insights has been the nuance in that the vagus isn’t “just” the rest‑and‑digest nerve. Depending on which branches are engaged, it can equally support alertness. Choosing breath‑focused tools (long exhales) yields calm; choosing exercise taps into alerting pathways. Recognizing this dynamic allows one to consciously steer their physiological and mental states in real time.
Neuroplasticity, Focus, and the Vagal-Cholinergic Pathway
Beyond its role in autonomic balance, the vagus nerve also supports cognitive performance by enhancing the brain’s neurochemical environment for learning and attention. When vagal afferents stimulate brainstem centers like the locus coeruleus and nucleus basalis, they help trigger the release of norepinephrine and acetylcholine, two neurotransmitters essential for focus, motivation, and neuroplastic change (Huberman, 2025; Nieuwenhuis, Aston-Jones, & Cohen, 2005).
These chemicals enhance activity in key regions like the dorsolateral prefrontal cortex (DLPFC), which governs executive function, attention, and working memory (Hasselmo & Sarter, 2011). This means that when vagal tone is elevated, such as after breathwork, movement, or focused exertion, this prefrontal region becomes more efficient and better able to regulate thought, emotion, and decision-making.
Acetylcholine is especially powerful in this context. It increases the brain’s signal-to-noise ratio, allowing it to more precisely encode meaningful information while filtering distractions (Hasselmo & Sarter, 2011). Physical exercise and deliberate vagal stimulation naturally boost acetylcholine levels. Some individuals also explore cholinergic support via compounds like Alpha-GPC (a choline donor that crosses the blood-brain barrier), or low-dose nicotine, which binds to nicotinic acetylcholine receptors and has shown benefits for working memory and attention when used carefully in clinical settings (Bellar et al., 2015; Newhouse, Singh, & Potter, 2004). These are not necessary tools, but they highlight the role of the vagus nerve in modulating the very systems that underlie learning and cognitive agility. By consciously engaging this vagal-cholinergic loop through natural means, such as breath, movement, or vocalization, we can support neuroplasticity, deepen focus, and foster resilience in both mind and body
Further Physiological Insights
Complex Dual Functionality of the Vagus Nerve: The vagus nerve is not just a calming parasympathetic nerve but a mixed nerve containing both sensory and motor fibers. About 85% of its fibers transmit sensory information from organs to the brain, while 15% send motor commands from the brain to the body. This dual role is crucial for its broad influence on bodily homeostasis, mood, and alertness. Understanding this mixed functionality is essential for designing interventions targeting specific vagal pathways to achieve desired physiological or psychological outcomes (Huberman, 2025).
Heart Rate Variability and Autoregulation: The vagus nerve’s motor fibers originating in the nucleus ambiguous regulate heart rate by acting on the sinoatrial node, slowing heartbeats during exhalation. This mechanism underlies heart rate variability (HRV), a key biomarker of autonomic flexibility and health. Deliberate breathing techniques that emphasize prolonged exhales strengthen this pathway, improving HRV and autonomic balance over time. This pathway’s plasticity means that behavioral practices can enhance or degrade vagal control, impacting stress resilience and longevity (Huberman, 2025).
Exercise as a Vagal Alertness Stimulus: Movement of large muscle groups triggers adrenal release of adrenaline, which activates vagal sensory fibers. These fibers relay signals to the brainstem’s nucleus tractus solitarius (NTS), which then activates the locus coeruleus to release norepinephrine, increasing brain-wide alertness. This pathway explains why engaging in high-intensity physical activity can overcome lethargy and brain fog by activating endogenous neurochemical systems without pharmacology. It also highlights the vagus nerve’s role in coupling body and brain states, facilitating motivation and cognitive performance (Huberman, 2025).
Gut Serotonin and Brain Mood Regulation via Vagus: While 90% of the body’s serotonin is produced in the gut, it does not enter the brain directly. Instead, serotonin in the gut binds to receptors on vagal sensory neurons, which signal the dorsal raphe nucleus in the brainstem to release brain serotonin. This gut-brain serotonin axis is influenced by dietary tryptophan and the microbiome’s health, linking nutrition and gut health to mood and neuroplasticity. This insight supports dietary and probiotic interventions as adjunctive strategies for mood disorders and general well-being (Huberman, 2025).
Physiological Sigh and Rapid Vagal Activation: The physiological sigh, or a double inhale through the nose followed by a prolonged exhale through the mouth, leverages both mechanical and chemical vagal pathways to rapidly decrease sympathetic nervous system activity and increase parasympathetic tone. This breathing method can be used on-demand to calm the nervous system faster and more robustly than simpler breathing or ear-rubbing techniques, demonstrating a powerful non-pharmacological tool for stress regulation (Huberman, 2025).
Vocalization Techniques for Vagal Engagement: Humming and gargling produce vibrations in the throat that mechanically stimulate vagal fibers innervating the larynx and related structures. Extending the ‘H’ sound in humming particularly engages these fibers, promoting parasympathetic activation and heart rate deceleration similar to breathing techniques. This finding validates traditional practices in yoga and meditation, offering accessible methods to induce relaxation and improve autonomic regulation (Huberman, 2025).
Context-Dependent Vagal Effects on Alertness and Calm: The vagus nerve’s effects are context-dependent and branch-specific. Some vagal pathways promote calm and rest, while others enhance alertness and sympathetic activity. This nuanced understanding dispels the myth that vagal activation always induces relaxation. It emphasizes the importance of targeting specific branches or using appropriate behaviors (e.g., breathing exercises vs. physical activity) to achieve the desired physiological or psychological state (Huberman, 2025).
Key Practical Tools
Physiological sigh: two inhales through the nose + long exhale through the mouth. Use this on‑demand to swiftly enhance HRV and calm the nervous system (Huberman, 2025).
Full‑body movement (especially high‑intensity): activates vagal‑mediated alertness via adrenal‑vagal pathways, great for focus and learning (Huberman, 2025).
Diet support: tryptophan‑rich and fermented foods support gut‑based serotonin → vagal → central serotonin signaling (Huberman, 2025).

The spiritual histories of Europe and Asia between the ninth and eighteenth centuries reveal both stark contrasts and surprising parallels. While the Holy Roman Empire represented a distinctly Christian civilization in Europe, Asia contained a vast spiritual mosaic shaped by Buddhism, Hinduism, Daoism, Confucianism, and emerging new traditions. Examining them side by side highlights not only their differences, but also their shared struggles with orthodoxy, reform, and the search for direct spiritual experience.
Early Medieval Period (800–1000 CE)
In Europe, the coronation of Charlemagne in 800 marked the symbolic beginning of the Holy Roman Empire, embedding Christianity as the unifying spiritual and political authority. Benedictine monasteries flourished, emphasizing discipline, prayer, and scholarship (McKitterick, 2008). Missionaries spread Christianity into Central and Northern Europe, solidifying the Church’s cultural dominance.
At the same time, Asia was undergoing significant transformations. In India, the philosopher Śaṅkara refined Advaita Vedānta, a non-dualistic vision of ultimate reality that would remain influential for centuries (Deutsch, 1988). Buddhism continued to flourish in China and Tibet, with Chan (Zen) Buddhism emphasizing meditation and direct awakening (Faure, 1993). In Japan, esoteric Buddhist schools such as Shingon and Tendai were introduced, while in Tibet royal patronage ensured Buddhism’s lasting establishment (Kapstein, 2006).
High Medieval Period (1000–1200 CE)
The Holy Roman Empire entered the high medieval period with expanding papal authority and the rise of scholastic theology. Thinkers such as Anselm of Canterbury laid the groundwork for reasoned approaches to faith (Southern, 1990). The First Crusade (1095) demonstrated the deeply spiritual yet militant expression of medieval Christianity, as the Church sought to extend its influence beyond Europe (Tyerman, 2005).
Across Asia, parallel movements of spiritual renewal were unfolding. In India, devotional currents of the Bhakti movement began to emerge, stressing heartfelt devotion over ritual and caste (Hawley, 2015). In China’s Song dynasty, Neo-Confucianism was synthesized by Zhu Xi, blending moral philosophy with metaphysics (De Bary, 1981). In Japan, Pure Land Buddhism spread among commoners, offering salvation through simple faith, while Zen Buddhism began its ascent (Suzuki, 1996). Korea’s Goryeo dynasty witnessed the maturation of Seon (Zen) Buddhism, and in Tibet, the Kagyu and Sakya schools gained structure and prestige (Samuel, 2012).
Later Medieval Period (1200–1400 CE)
By the thirteenth century, scholasticism reached its height in Europe with Thomas Aquinas, while Gothic cathedrals symbolized the union of beauty, architecture, and faith (Le Goff, 1988). Alongside official orthodoxy, Christian mystics such as Meister Eckhart and Hildegard of Bingen emphasized direct union with God, reflecting a deep hunger for personal spiritual experience (McGinn, 2006). At the same time, inquisitorial structures were established to guard orthodoxy and suppress deviation.
In Asia, spiritual life was equally dynamic. India witnessed the flowering of Bhakti poets such as Kabir, who challenged caste divisions and stressed unity with the divine (Hawley & Juergensmeyer, 1988). Chan Buddhism continued in China, alongside Daoist inner alchemy (neidan), which cultivated the transformation of essence, energy, and spirit (Robinet, 1993). In Japan’s Kamakura period, Zen influenced art, poetry, and even the martial discipline of the samurai (Addiss, 1989). Korea maintained its Buddhist culture, while Tibet received Mongol patronage that elevated the Sakya school to prominence (Kapstein, 2006).
Early Modern Period (1400–1600 CE)
Europe’s spiritual climate shifted dramatically between the fifteenth and sixteenth centuries. The Renaissance revived humanist inquiry, while the Protestant Reformation, beginning with Martin Luther’s theses in 1517, fractured Catholic unity across the Holy Roman Empire (MacCulloch, 2003). Wars of Religion ensued, and the Catholic Counter-Reformation sought to reclaim spiritual authority through renewed discipline, missionary zeal, and the Jesuit order (O’Malley, 1993).
In Asia, this same era was one of remarkable religious synthesis and renewal. In India, the Bhakti movement expanded further, and Sikhism was founded by Guru Nanak, offering a new synthesis of devotion and ethical practice (McLeod, 2009). In Ming China, Neo-Confucianism became the dominant ideology, though often blended with Buddhist and Daoist practices (Angle & Tiwald, 2017). Japan’s Zen traditions flourished in art, gardening, and tea ceremony, intermingling with Shinto rituals (Suzuki, 1996). Korea’s Joseon dynasty elevated Neo-Confucianism as state orthodoxy, though Buddhism persisted among common people (Deuchler, 1992). Tibet saw the rise of the Gelug school, and the institution of the Dalai Lama emerged as both spiritual and political authority (Samuel, 2012). Across Southeast Asia, Theravāda Buddhism spread and took firm root as the primary spiritual framework (Skilling, 2024).
Late Early Modern Period (1600–1800 CE)
In the Holy Roman Empire’s final centuries, the Thirty Years’ War (1618–1648) devastated Central Europe and redefined the balance between faith and politics. The Enlightenment further challenged ecclesiastical authority by placing reason and empirical science above dogma (Israel, 2001). By 1806, the Holy Roman Empire had dissolved, marking the end of a millennium of Christian-imperial identity.
Meanwhile, Asia entered an age of spiritual consolidation. In Mughal India, Emperor Akbar experimented with religious syncretism, while Sikhism solidified into a distinct faith (Eaton, 2019). In Qing China, Confucian orthodoxy reigned, but Jesuit missionaries introduced Christianity and Western science, leading to cultural exchanges and tensions (Brockey, 2007). Japan’s Edo period tightly regulated Buddhism but saw a revival of Shinto and Neo-Confucian ethics (Najita, 1987). Korea remained staunchly Confucian while underground Catholicism began to spread (Grayson, 2013). Tibet’s Gelug school solidified its control under successive Dalai Lamas, while Theravāda monasteries remained the heart of spiritual life in Southeast Asia (Skilling, 2024).
Each bar represents the approximate centuries during which each spiritual or philosophical system was prominent:
Christianity throughout the entire Holy Roman Empire period.
Advaita Vedānta, Buddhism, and Neo-Confucianism maintained long continuous influence.
The Bhakti and Zen movements arose in the middle centuries.
Sikhism appeared later in the 15th century.
Theravāda Buddhism spread widely across Southeast Asia beginning around the 12th century.
Epilogue: Why This Historical Comparison Matters Today
Understanding the spiritual evolution of Europe and Asia between 800 and 1800 CE is not just an academic exercise; it is a mirror reflecting the origins of our modern worldviews, ethical systems, and inner struggles. The lessons drawn from these historical traditions are profoundly relevant to the 21st century in several ways.
1. Revealing the Roots of Modern Ethics and Culture
The Holy Roman Empire’s Christian moral codes and Asia’s pluralistic philosophies, Confucianism, Daoism, Hinduism, and Buddhism, remain embedded in global culture today. Western concepts of justice, duty, and conscience evolved from medieval Christian theology, while Asian societies continue to be guided by Confucian filial values and Buddhist compassion. These differing spiritual foundations still influence how nations prioritize community, governance, and moral responsibility (Wei-ming, 1996). By tracing these roots, we better understand the moral diversity that defines global civilization.
2. Recognizing Cycles of Reform and Awakening
Every civilization has faced moments when inherited belief systems no longer sufficed. Europe’s Protestant Reformation and Enlightenment paralleled Asia’s Bhakti, Zen, and Neo-Confucian renewals, each reasserting inner experience over rigid dogma. In today’s world, the modern wellness movement, mindfulness training, and the integration of Eastern practices into Western medicine echo these cycles of rediscovery (Wallace, 2011). History shows that when spirituality grows stale, humanity instinctively turns inward for renewal.
3. Encouraging Cross-Cultural Understanding
Globalization has brought humanity into daily contact with belief systems that once evolved in isolation. Knowing how religions and philosophies once intersected through the Silk Road, the Jesuit missions, and early global trade, builds empathy and intercultural awareness (Said, 2001). In an era of cultural polarization, this understanding promotes tolerance and cooperation. Recognizing that different civilizations have wrestled with the same existential questions, of identity, morality, and transcendence, reminds us of our shared human story.
4. Balancing Science and Spirituality
The Enlightenment’s elevation of reason and Asia’s cultivation of experiential wisdom represent complementary, not conflicting, pathways to truth. Modern neuroscience’s validation of meditation, quantum physics’ exploration of interconnectivity, and psychology’s adoption of mindfulness bridge these once-divided worlds. Revisiting their historical interplay invites a more integrated model of consciousness, one where empirical knowledge and inner experience are seen as allies in understanding human potential (Wallace, 2011).
5. Guiding Personal and Collective Transformation
From Christian mystics and Zen monks to Confucian scholars and yogic sages, these traditions emphasized transformation through discipline, awareness, and service. The same principles now inform stress reduction, leadership development, and modern psychotherapy (Kabat-Zinn, 2013). Their enduring message is that the path to mastery of body, mind, and soul, requires both inner stillness and outer effort. As in the past, growth today demands the integration of reflection with action, intellect with humility, and spirituality with practicality.
Conclusion
The parallel journeys of the Holy Roman Empire and the diverse spiritual traditions of Asia reveal the ongoing dance between order and enlightenment, faith and reason, structure and spontaneity. Both East and West pursued truth through different means, yet their destinies converged in one universal search: to refine the human being. By studying these epochs, we rediscover not only where humanity has been but also where it might go next, a synthesis of ancient wisdom and modern understanding, offering hope for a more conscious, compassionate, and balanced future.

In today’s fast-paced world, stress-related conditions are on the rise. Autogenic therapy, also known as autogenic training, offers a powerful way to counterbalance modern stress through a simple, structured set of mental exercises. Developed by German psychiatrist Johannes Heinrich Schultz and coined the term in 1928, this self-regulation technique continues to help people worldwide regain calm, reduce anxiety, and improve overall well-being.
What Is Autogenic Therapy?
Autogenic therapy is a relaxation technique that uses self-suggestions to bring about physical and emotional calmness. The practice involves six standardized exercises focusing on sensations like:
Heaviness and lightness in the limbs
Warmth
Heartbeat regulation
Breathing awareness
Abdominal warmth
Forehead cooling (Luthe & Schultz, 1969)
These exercises promote a shift in the autonomic nervous system toward the parasympathetic or “rest and digest” mode, reducing the physiological effects of stress.
Although not usually classified as meditation, autogenic therapy shares similar traits with meditative and mindfulness-based practices:
Present-moment awareness
Regulation of breath and heart rate
Promotion of internal balance and nervous system calm (Melnikov, 2021)
A Shared Language: Body Awareness in Mind–Body Disciplines
What’s especially fascinating is that autogenic therapy aligns with ancient mind–body traditions found in:
Tai Chi
Qigong
Yoga
Martial Arts
These disciplines often guide practitioners to cultivate bodily sensations that echo those used in autogenic training:
Feelings of lightness or heaviness in the limbs
Generating internal warmth (often associated with breath or energy flow)
Focusing on the heartbeat or breath rhythm
Stimulating abdominal heat (known in some traditions as dantian activation)
Creating a sense of coolness or spaciousness in the head or forehead
These parallels suggest that human self-regulation, through structured inner awareness, is a timeless and cross-cultural approach to stress relief, energy balance, and health.
Benefits of Autogenic Training
When practiced consistently, autogenic therapy has been shown to:
Its simplicity and accessibility make it a popular choice for those looking for holistic, non-invasive ways to manage daily pressures and improve health.
How It Works
Each autogenic session involves repeating mental phrases such as, “my arms are heavy and warm,” while reclining or sitting in a quiet space. The mind’s focus on these specific body cues leads to a measurable shift in physiology, lowering stress hormones, heart rate, and muscle tension (Luthe & Schultz, 1969; Stetter & Kupper, 2002).
Many people practice autogenic training independently, with audio guidance, or under the supervision of a certified therapist.
⚠️Caution: Autogenic Training and Psychotic Disorders
While autogenic therapy is safe for most individuals, it may not be appropriate for people with psychotic disorders, such as schizophrenia or bipolar disorder with psychotic features (Fletcher, 2023. Here’s why:
1. Exacerbation of Symptoms
The use of self-suggestion and imagery can potentially worsen hallucinations or delusional thinking in vulnerable individuals (Kanji, 2006; Stetter & Kupper, 2002).
2. Potential for Dissociation
The deep relaxation states achieved may induce altered consciousness or dissociation, which can be unsettling or unsafe for those with psychotic tendencies.
3. Difficulty in Reality Testing
Psychotic conditions often impair one’s ability to distinguish between internal experience and external reality. Autogenic training might blur these lines further (Stetter & Kupper, 2002).
4. Medication Disruption Risk
Some individuals may believe that relaxation practices can replace essential medication, potentially leading to non-compliance and relapses (Mueser & Jeste, 2008).
Because of these risks, it’s essential that individuals with psychotic disorders engage in any form of relaxation training only under professional medical supervision. More recent research has suggested that autogenic therapy may actually help those suffering from schizophrenia (Breznoscakova et al., 2023).
Final Thoughts
Autogenic therapy offers a safe, evidence-based, and self-directed method to reduce stress and promote relaxation. Its emphasis on internal sensations such as warmth, breath, heartbeat, and mental stillness, places it in harmony with long-standing Eastern practices like tai chi, yoga, and qigong.
For most people, autogenic therapy can serve as a cornerstone of a healthy lifestyle, but those with complex mental health conditions should consult with trained professionals to ensure it is suitable.

My Traditional Approach to Acupressure, Massage, and Herbal Therapy
As both a long-time practitioner and teacher of holistic wellness, martial arts, and Traditional Chinese Medicine (TCM), I have found that the health of our hands is often underestimated. Our hands connect us to the world, allowing us to create, heal, and express, but they are also vulnerable to stiffness, poor circulation, and overuse injuries, especially in our modern, screen-driven culture.
In my lecture and video presentation, I shared a traditional system of hand conditioning that I have personally practiced and taught for many years. This unique approach integrates acupressure, therapeutic trauma, herbal therapy, breathing techniques, and mindful movement. All designed to restore vitality, enhance flexibility, and promote whole-body energy flow.
A Philosophy of Health, Not Hardness
In the martial arts world, hand conditioning is often associated with building hardened fists and thick calluses. I take a different view.
The method I teach is not about brute strength or desensitization. It is about stimulating circulation, promoting healing, and enhancing energy (Qi) flow throughout the entire body.
Using bean-filled bags (I recommend soybeans, mung beans, or chickpeas), we create strategic trauma or gentle, controlled impacts that trigger the body’s natural healing response. This principle, rooted in ancient wisdom, leverages micro-trauma to increase blood flow, strengthen tissues, and support overall wellness (Zhou, 2009).
Hands as Microcosms of the Body
In my lineage or martial arts system, the hands are viewed as a map of the entire body, a concept validated by reflexology and TCM meridian theory.
We focus on stimulating Jing-well points located on the fingertips—powerful gateways for regulating energy flow (Deadman & Al-Khafaji, 2007).
I also reference Japanese and Korean reflexology maps, which beautifully illustrate how the fingers and palms correspond to internal organs and bodily systems (Ang et al., 2021).
When we work the hands with mindful techniques, we influence not just the hands themselves, but the entire body and mind.
Breathing: The Missing Link
A key element in my lineage is Qigong (breath work), a deep, nasal breathing pattern combined with proper tongue positioning on the upper palate.
This breathing technique activates the parasympathetic nervous system, promoting relaxation, improving circulation, and harmonizing Qi flow (Sancier, 2001).
When combined with hand exercises, this breathwork turns a simple routine into a powerful integrative practice that nourishes body, mind, and spirit.
The Practice in Action
During my presentation, I guided participants through a progressive series of hand conditioning techniques, including:
Pinching, clapping, and crab-finger movements to stimulate circulation and flexibility.
Percussion on bean bags to activate Jing-well points and trigger micro-trauma healing.
Twisting, stretching, and massage for the palms, knuckles, thumbs, and wrists.
External application of herbal tinctures, which I personally formulate using apple cider vinegar, frankincense, and traditional Chinese herbs, to reduce inflammation and enhance post-exercise recovery (Xu et al., 2013). (Note: these tinctures are for external use only and should not be ingested.)
Real-World Applications
One of the most exciting aspects of this practice is its practical value:
Certain finger acupressure points can be used to help revive a fainted person; a technique I demonstrate and encourage students to learn.
Regular practice can reduce symptoms of arthritis, improve joint mobility, and enhance overall hand resilience, making it valuable not just for martial artists, but for anyone seeking greater hand health and functional longevity (Kim et al., 2015).
Balance Is Key
In my teaching, I stress the importance of balance and recovery:
Do not overdo the hitting exercises! Allow at least one day of rest between sessions.
Always follow with herbal application to soothe the tissues and prevent over-inflammation.
Listen to your body. This is a lifelong practice, not a race for quick results.
This approach embodies the philosophy I teach in all of my wellness work: true progress comes from harmonizing stimulation with restoration.
Closing Thoughts
For me, this hand conditioning system is much more than an exercise routine. It is a gateway to whole-body vitality and a deeper connection with the subtle currents of energy that animate us.
By combining traditional acupressure, mindful breathwork, herbal therapy, and thoughtful movement, we can restore the natural vitality of the hands, which in turn enhances our overall health, energy balance, and functional well-being.
I encourage you to explore this practice with patience, mindfulness, and care. Your hands and your entire body will thank you.
