Yoga believes that regular practice of some particular asanas and pranayamas strengthens nervous system and help to face stressful situation positively. Yoga can help promote a healthier nervous system.

Ancient yogis fully understood vulnerability of spine and tendency for slight spinal misalignments to occur. They also knows that if spine was kept flexible by yogasana, there would be much less chance of spinal misalignments. Some of asanas will even correct some minor misalignments.

Yoga  poses directs blood flows to brain and spine and helps in improving functions. Nerves from brain and spine go to every tissue in body depends upon health of brain and spine. Asanas and pranayama cause an increase in circulation of blood to brain and spine which stimulates nerve cells. This results in increased vitality and improved nerve functions. Since nerves from spine go to all organs and glands of body , a healthy spine obviously plays an important role in vitality and rejuvenation. When yogasanas are performed , respiration and metabolic rates slow down , consumption of oxygen and body temperature drops. During exercise, however, breath and metabolism speed up oxygen consumption rises, and body gets hot. Yoga postures and breathing exercises tends to arrest catabolism whereas exercises promotes it. In addition , specific yogasanas affects on glands and internal organs, and to alter electrochemical activity in nervous system. Mostly asanas imposed on spine and whole trunk exercises muscles, makes spinal column more flexible and stimulates spinal nerves. It has strong influence on abdominal muscles, alternately stretching and compressing them as body bend or twist from one direction to other. Most of asanas and pranayamas enhances pranic flow in samana region, around neval. Samana region has Manipur chakra, a plexus of major nadies or pranic channels, supplying whole body. On  emotional and psychic levels for Spinal diseases sufferers asanas represents  a mean of managing knots and problems of life.

Yoga philosophy attributes most problems in Spinal diseases due to insufficient life force, either in body as a whole or a blockage of life force localized to one part of body leading to decreases in immunity and increased susceptibility to infections. Yoga emphasized treatment of root cause and not to symptoms. Yogic philosophy and practices have been used for treatment as well as an adjuvant to available therapies in different states of injury. Yoga can efficiently aid to maintain the milieu interior of body. Practice of yoga leads to a state of positive health, attitude and enhanced immunity. There is also better oxygen utility , lesser state of autonomic arousal , with shift of sympathovagal balance towards vagal predominance, increased attention and better sleep. It also reduces anxiety and stress which is very common in chronic Spatients and enhances mood resulting in sense of inner peace and purpose, which has far- reaching health benefits. Many uncertainties and methodological problems, both theoretical and well as practical issues, surround research pertaining to yoga in health and disease.  For many patients life seems complicated and their problem appear to difficult to solve. Yogic asanas and pranayamas give an insight and inspire a systematic approach to untying tangled knots of life.

Modernization of daily life makes life easier but unhealthy behaviours responsible for increasing the mortality of cardiovascular, cancers, diabetes, and respiratory diseases. There is increasing evidence that following a healthy lifestyle including appropriate naturopathic diet, yogic practices and healthy weight can provide significant cardiovascular and metabolic benefits. From that we come to a conclusion that different modern life style patterns affect our health physically, psychologically, and socially. Yoga is crucially concerned with how we live our life with respect to:

• Our own personal health, hygiene and well being
• Our personal environment
• How we interact with other people
• How we work and behave in general
• Our life as learning process
• Our relationship with ultimate consciousness

Yoga is an ancient system of philosophy, lifestyle and techniques that evolves whole person. Physical, vitality, mind, and emotions, wisdom, ethics and higher quality of relationships and realization of spiritual reality of each of us. Different lifestyle practices make life healthier.

General lifestyle: Considerations such as simplicity in our life, efficiency, regularity, moderation., activity, and monitoring our physical intake such as foods, drinks, air and drugs. We also watch quality of our mental and emotional intake, especially from people in our life, media etc.

Raja yoga: Maharishi Patanjali was very specific about positive effect on our peace of mind from good ethical relationships with others, and caring for our own wellbeing, He enumerated these in first two limbs of raja yoga, Yamas and Niyamas.

Karma Yoga: This is a lifestyle principle which  very much needs to be understood in west, It is way of living and working for others and world , with detachment from personal expectations and fruits of our efforts, with maximum awareness, concentration and absorption in task at hand.

Bhakti Yoga: The yoga of devotion, process of expressing our emotions in a flow of devotion to divine and in service to others.

Jnana Yoga: The yoga of evolution of our knowledge and expansion of our realization about fundamental realities and meanings of highest consciousness.

It is not easy to  change , but often just minor improvements in a destructive lifestyle can have great benefits. Some people have a very hectic life, and they often don’t even realize it. They overwork, take their work home with them and do it late at night, and indulge in activities that cause them various kinds of anxieties and worries. A number of tendencies complicate people’s live. One is inability to say no to people, so they accept more than they can handle, and end up handling none of it properly. If we stressed and seem to be running around in circle, it is a good idea to ask ourselves if our life has become too complicated. Regular meals and regular yoga practices are also conductive to a lifestyle that keeps us in a stable and balanced condition, and help in our endeavours to evolve our personality. Above lifestyle practices of yoga -styles, we can live our lives and enable us to evolve aspects of our nature.

Slow and static yogic practices not only relaxes the body and mind, but certain poses can also release congestion and enhance overall well-being. Relaxation and stress reduction have actually been linked to a stronger immune system. Yoga is an ancient science, which gives not only a healthy body but also a sound mind. Yoga has been shown to have effects on most physiological systems of the body and harmonies balance of body and mind.

Yogasanas like Simhagarjan asana, Kasthatakshan asana, Tadasana, Ardhamatsyendra asana, Bhujanagasana or Paschimottan asana, if they execute in a sequential order, they minimise strain on some muscles and joints and bring them into operation antagonistic group of muscles. During yoga practice it is also considerate that not letting muscles pulled for too long in one direction by gravity. Yogasanas primarily aim should be at improving muscle tone and plasticity of muscles and joints. With sudden onset of stress, muscles tense up all at once, and then release their tension when the stress passes. Chronic stress causes the muscles in the body to be in a more or less constant state of guardedness.

This stress get “under the skin” to influence immunity. Immune cells have receptors for neurotransmitters and hormones such as norepinephrine, epinephrine, and cortisol, which mobilize and traffic immune cells, ideally preparing the body to mount an immune response if needed. Recent evidence shows that immunological cells (e.g., lymphocytes) change their responsiveness to signaling from these neurotransmitters and hormones during stress. However, immunological responses are biologically and energetically costly, and over time, chronic stress produces negative systemic changes both in immune trafficking and in target tissues.

Yogic practices are primarily improving muscle tone and plasticity of muscles and joints which is affected by omnipresent stressers during this corona pandemic. Yogic practices activating stretch reflexes at level of spinal cord. Thus neural impulses that are needed to traverse long sensory pathways up to ascending reticular formation and further through Thalamus to cortex are spread loss of energy. This automatically helps in maintaining alpha waves activity of EEG by not disturbing thalamocortical pathways. This ensures a resting , meditative activity at level of cerebral cortex.

Static comfortable postures and pranayama like Nadishodhan and Bhramari pranayama accompanied by a meditative state, dampens the inflow of sensory impulses to brain. This in turn , causes less stimulation of ‘ Emotional brain’ (Limbic Cortex – Hypothalamus – Anterior Pituitary) and therefore less visceral disturbances to disturb equilibrium. Furthermore , inhibition of synapses at neuro- muscular junctions in its turn, leads to reduction of sensory input further.

Since pranayama and meditation involves a lot of attention and concentration of mind followed by – an initiation of relaxed emotional state all good effects of relaxation response become available after practice.

Yogic asanas, pranayamas, cleansing practices like Neti and Kunjal relieving stress responses at body and mind. Some particular relaxation practices like Yoga Nidra effects the major endocrine glands and improve the bodily functions during stress conditions and hence improve immunity also.
