The headache after each exercise is related to the lack of physical activity, and it may occur after sudden strenuous activity. This is a benign post-exercise headache, which may occur after every exercise, or may be triggered by any intensity of exercise, and may come on suddenly. The symptomatic relief method is for the patient to rest, and those who usually lack exercise should exercise gradually and increase the amount of exercise appropriately after enhancing physical fitness, and the headache can still be relieved.
