STRESS
The feeling of stress is a combination of our perception of events or situations and our body’s physiological reaction. Work issues, difficulties, challenges, obstacles, deadlines, papers, tests, athletic events, performances, family problems, and tragic events are only a few of the situations that can instigate stress. Even joyous events like holidays, weddings and new additions to a family can also exacerbate stress. Natural disasters, world conflicts, tragedies, and stories of suffering and heartbreak, even those occurring on the other side of the world, can have wide ranging impacts, affecting people’s mental health.

One of the ways in which we respond to stress is through our fight-or-flight response. This is a combination of the activation of our sympathetic nervous system and specific hormonal pathways which result in the release of cortisol from the adrenal glands. Cortisol is one of our primary stress hormones, and is often used to measure the stress response.  Stress in itself is not necessarily a bad thing. Immediate, or acute stress, can often be as motivating, as it can be activating. We hear stories of people being able to accomplish physical feats in emergency circumstances because cortisol increases blood pressure, heart rate, and blood sugar, as well as increasing mental focus. Because the stress response increases mental focus, it can often help us meet a deadline or finish a project. But too much stress, or constant stress with no respite for the body and mind, can interfere with numerous physical and mental abilities.

On a long-term basis, chronic stress can be damaging. Stress hormones including cortisol decrease the responsiveness of our immune system. They also increase blood sugar levels as well as blood pressure and heart rate, helpful in a crisis, but not for long-term health and wellbeing.  This is where how we respond to stress can have a significant impact.



















YOGA AND STRESS
The practice of Yoga is well-demonstrated to reduce the physical effects of stress on the body, and has even been found to lower cortisol levels. This effect is noticeable, and it is one of the primary reasons why people often take up Yoga. People find that they feel more relaxed after practicing Yoga. The asana, or physical postures of Yoga, are helpful for reducing muscular tension, which reduces stress. We have a tendency to store stress not only in our nervous system,
but distributed throughout the musculature and other tissues of the body; our digestive system,for example, responds very quickly to stress. Yoga can be a valuable and effective tool for releasing this stored stress. This can be true even for post-traumatic stress and recovering from the after-effects of traumatic events.

Yoga includes not only the asana or physical postures, but most Yoga classes end with savasana, or a pose of relaxation. Some classes include a guided relaxation where the teacher leads students through a progressive relaxation of the body, which further reduces the experience of stress.  Yoga also includes meditation and breathing practices (pranayama) as well as a set of ethical precepts and observances (yamas and niyamas). Meditation, the ethical precepts and observances, focused relaxation techniques, and working with the breath all have beneficial stress reducing qualities, through improving our relationships with the various aspects of our inner nature as well as affecting our psychology and physical body.

YOGA, THE BREATH AND STRESS
Working with the breath can be a particularly effective method for treating a negative response to stress.  When we are experiencing stress, our breathing tends to become shallow and rapid. Shallow and rapid breath further stimulates the body’s stress response, and we can become caught up in an ineffective breathing pattern that only causes more stress. Many yoga techniques emphasize slowing and deepening the breath, which activates the body’s parasympathetic system, or relaxation response. Just by changing our pattern of breathing, we can significantly affect our body’s experience of and response to stress. This may be one of the most profound lessons from yoga practice.
