An estimated 80 to 90 percent of visits to the doctor are stress-related but only less than 3% of doctors talk to their patients about how to reduce stress. Yoga, meditation, and other mind-body practices train your body and mind to be able to cope with stress better and improve overall health and well-being.
In a national survey, over 85% of people who did yoga reported that it helped them relieve stress. Exercise is a very useful way to relieve stress, but yoga is different from spinning class or weight-lifting in that it powerfully combines both physical fitness with an underlying philosophy of self-compassion and awareness. One of the main concepts in yoga is being non-judgmental toward both yourself and others, which is a powerful tool for stress relief since much of our stress comes from us being hard on ourselves or frustrated with others.
A fundamental principle of yoga is that your body and mind are one and connected. Stress in one domain will affect the other and vice versa. Many of us live primarily in either our mind or our body, which creates imbalance and even a lack of awareness. For example, people with very analytical careers may spend a lot of time in their mind, and may not realize how much tension is stored in their body. Or if you’re an athlete, you may be keenly aware of your body, but could benefit from becoming more aware of your mental state. Wherever you fall on this spectrum, yoga helps balance and tone the connection between your body and mind.
Yoga also trains your counter-stress response system called the parasympathetic nervous system. With regular yoga practice, your chronic daytime stress hormone levels drop and your heart rate variability increases, which is the measure of your ability to tolerate stress. This has been shown to improve even after a few sessions of yoga.
