| The ANS is the other part of the nervous system that can manage numerous involuntary functions, including heartbeats, digestion, breathing rate, and secretions in the glands. These are almost automatic and can either be working in the SNS or the PNS. Stress stimuli prepares the body for fight or flight by releasing SNS, which increases heart rate and pupils dilation, redistributes blood flow to vital organs. PNS, while further conserving energy, facilitates sleep and digestion through slowing of heart rates, pupil constriction, etc processes. A healthy ANS is always a must to maintain general health. It remains poised between activities of the SNS and PNS through stress management techniques that include meditation, deep breathing exercises besides physical exercise. Nutritional balance rich in antioxidants, vitamins-especially B- complex-and minerals is an important conditioner that facilitates healthy working of nerves and promotes healthy functioning of the nervous system. |
