There are many reasons why the nerves are always in a hyperactive state, including physiological and pathological reasons. Physiological causes are mainly caused by drinking too much strong tea or coffee during the day, or too much tension in daily work, which can be relieved by relaxation. For temperamental or pathological nervous hyperactivity is generally a symptom of some diseases, such as hyperthyroidism and mania, which should be treated symptomatically while combining work and rest with long hours of exercise and games. Mania is a psychological factor and should be investigated in the neurology department of a regular hospital and the cause of the cure should be determined. If mania is diagnosed, it should be actively treated under the guidance of a doctor to get rid of the psychological shadow and restore the normal state of nerves as soon as possible.
