When we exercise or do activities requiring fast movements or more power, we stimulate sympathetic nervous system. As a result, the following occurs: rapid breathing, rapid heartbeat, sweating, higher blood pressure, blood becomes more acidic, lactic acid level gets higher, the body exhausts itself. Therefore, exercise has positive and negative effects. However, in order to gain positive effects, it is necessary to perform body movements and positions in a slow and conscious manner by respecting the limits of the human body and without overstraining, not to stimulate the sympathetic nervous system, but the parasympathetic one. As a result, all bodily functions remain normal. Yoga exercises do not exhaust the body. On the opposite, they fill the body with energy and make it strong and fresh.
