Eating a balanced diet, drinking plenty of water and exercising regularly are a few recommended ways to take care of the nervous system, according to WebMD. It also helps to avoid smoking and drinking alcohol.
WebMD states that a balanced, low-fat diet protects the nervous system. This diet consists of fresh fruits, vegetables, whole grains and sufficient amounts of vitamins B6, B12 and folate. It is also important to drink plenty of water and other fluids to avoid dehydration, which can lead to memory problems and confusion. During exercise and hot weather, a person should drink 8 to 10 glasses of water or rehydration drinks before, during and after exercise. Sports drinks should be consumed when exercising for longer than an hour. Caffeinated drinks must be minimized, as they tend to increase dehydration and affect sleep.
Alcohol and illegal drugs affect the body's functions long after use, so people should avoid these bad habits, says WebMD. Moreover, it is essential to get plenty of rest every day. Diabetes and high blood pressure can decrease nervous system functioning, so following doctor's orders is important for those that suffer from either of these conditions. Also, being sure to protect oneself from head injuries.
