Reduction in disease conditions and medicine usage in
In a health survey that was conducted on Isha Yoga practitioners, more
than 500 respondents reported improvement in their disease status and
reduction in medication use.
Medical Research on the
Benefits of Inner Engineering
Neurocognitive tests show that Isha Yoga increases performances in attention-oriented tasks suggesting better distribution and faster allocation of attentional resources and enhanced sustained attention skills.
Enhanced mental capabilities6
The EEG study on meditators who practice the Shambhavi Mahamudra also showed higher levels of coherence between the right and left hemispheres of the brain. This greater brain synchronization leads to greatly enhanced mental capabilities like better learning ability, increased creativity, heightened mental clarity, and sharper intellect.
Increased alertness, awareness, and relaxation6
Neurophysiological studies using EEG revealed a substantial increase in delta and theta brain waves and markedly reduced beta and alpha brain waves when measured after 21 minutes of Shambhavi Mahamudra practice.
Increase in delta and theta waves are associated with deep relaxation and higher levels of mental focus. Reduced beta waves are associated with reduced mental tension and anxiety. Reduced alpha waves in conjunction with increased theta and delta waves are associated with conscious awareness of the subconscious mind.
These results support a drop in stress and anxiety, a boost in mental alertness and focus, and an increase in self awareness as a result of just 21 minutes of daily practice.
Reduced risk of heart diseases and improved cardiac function3
Heart Rate Variability studies show that Isha Yoga causes greater balance of the Cardiac Autonomic Nervous System, thereby enhancing the ability of the heart to respond better and more effectively to various stressful situations. This reduces the risk of many cardiac ailments like hypertension, angina, infraction, arrhythmias, etc.
Improved quality of sleep4
Polysomnographic study comparing Isha Yoga practitioners and matched controls showed a statistically significant improvement in the efficiency of sleep and lesser number of awakenings during sleep, indicating improved quality of sleep in Isha Yoga practitioners.
