| The autonomic nervous system (ANS) is a vital part of the nervous system responsible for regulating involuntary bodily functions, including heartbeat, digestion, respiratory rate, and glandular secretions. It operates largely unconsciously and is divided into two main branches: the sympathetic nervous system (SNS) and the parasympathetic nervous system (PNS). The SNS prepares the body for fight-or-flight responses in stressful situations by increasing heart rate, dilating pupils, and redistributing blood flow to essential organs. In contrast, the PNS conserves energy and promotes rest and digestion by slowing heart rate, constricting pupils, and enhancing digestive processes. Maintaining a balanced autonomic nervous system is crucial for overall health and well-being. Stress management techniques such as meditation, deep breathing exercises, and regular physical activity help balance SNS and PNS activity. A healthy diet rich in antioxidants, vitamins (especially B-complex), and minerals supports nerve function and overall nervous system health. |
