What's the matter with the headache in hot weather?

In summer, the temperature is high. When the weather is hot, people sweat a lot in order to dissipate heat and cool down. At this time, if water is not replenished in time, the blood volume of the human body will decrease, and the brain will be short of blood supply, which is prone to headaches.

2 Lowering blood pressure and headache

When the weather is hot, the human body will sweat a lot to dissipate heat. When sweating, the blood vessels on the body surface will expand, and the blood will be diverted from the inside out. The redistribution of blood will make the blood pressure of people with low blood pressure lower, thus causing headaches, which is medically called intracranial pressure or hypotensive headache.

3 headache due to low blood sugar

People often have headaches due to poor sleep, weak spleen and poor appetite in summer. The causes of this kind of headache are malnutrition and low blood sugar, which causes the brain to lack the necessary energy and produce headaches.

4 headaches when eating cold drinks

When people drink cold drinks in summer, because the hot mouth and mucous membrane can't stand the sudden stimulation, this stimulation causes vasospasm under the mucous membrane, and at the same time, it causes cerebral vasospasm reflexively for a short time, but it will make the brain unable to stand this sudden blood cut-off and can't make a quick stress response, thus causing headaches.
