Numbness all over the body when crying is a common phenomenon, mainly related to the time spent crying and the severity of crying. If you cry too long or have severe sobbing, on the one hand, it will lead to poor breathing, lack of oxygen in the body will lead to a numbness of the whole body. Another aspect is that hyperventilation, more air out, less air in will lead to excessive loss of carbon dioxide in the body, resulting in respiratory alkalosis will lead to general numbness, and sometimes the hands twitch to take hold. Elderly people or patients with underlying cardiovascular diseases should be alerted to cardiovascular emergencies when their whole body becomes numb when they become agitated. Insufficient blood supply to the brain or heart leads to poor central nervous circulation or poor peripheral circulation, severe acute cerebral infarction, cerebral hemorrhage or myocardial infarction, which is rare but cannot be ruled out, if the generalized numbness continues to not improve to go to the hospital in a timely manner.
