A regular yoga practice helps to reduce the levels of cortisol, the hormone released by the body during stress. Increased levels of cortisol can lead to blood sugar imbalance and diabetes, weight gain and obesity, immune system suppression, gastrointestinal problems, cardiovascular diseases and fertility problems. These problems are very common among people in high-stress jobs. During a yoga session, the body is trained to relax while doing poses that can be difficult. The more often you practice yoga, the more the body learns how to relax in a difficult situation. The brain will learn how to apply this even while you’re dealing with stressful conditions at work and at home.
