The headache appears after standing up after squatting: 1. Consider changes in cerebral blood flow causing cerebral vasospasm, cerebral blood supply deficiency resulting in dizziness, headache and other symptoms, usually try not to be too violent when standing up after squatting or lying down, and usually increase some aerobic exercise appropriately. 2. Consider the existence of postural hypotension in patients, resulting in insufficient cerebral perfusion, cerebral ischemia and hypoxia leading to headache. When the patient squats and then stands up, postural hypotension occurs, resulting in insufficient cerebral blood perfusion, cerebral ischemia and lack of oxygen, and headache symptoms. It is recommended that such people usually squat and then stand up slowly to give the body time to self-regulate, so that postural hypotension will not occur and headaches will not occur.
