Why do 17-year-old girls have headaches and vomiting when the weather is slightly hot?
Hello. Many people have this situation. The reasons may be as follows: First, the summer temperature is high, the summer heat is pressing, and the human body sweats a lot in order to cool down. If you don't replenish water in time at this time, the blood volume of the human body will be reduced, and the blood supply to the brain will be insufficient, leading to headache. In addition, when people sweat, the blood vessels on the body surface dilate and the blood is diverted from the inside out. The redistribution of blood will lower the blood pressure of people with low blood pressure, thus causing headaches, which are medically called intracranial pressure or hypotensive headache. Second, in summer, people often have headaches because of poor sleep, weak spleen and stomach and poor appetite. This kind of headache is caused by malnutrition and low blood sugar, which leads to the lack of necessary energy in the brain and headache. Third, people are used to drinking cold drinks in summer. Although cold drinks are sweet and refreshing, some people will have a headache after drinking one. This is because the burning mouth and mucous membrane can't stand the sudden stimulation, causing submucosal vasospasm. At the same time, although reflex cerebrovascular spasm is short-lived, it will make the brain unbearable.
