It's very hot and I have a headache. Is it caused by the weather?

It is probably caused by the hot weather.

Hypovolemia and headache

1, the temperature is high in summer. When the weather is hot, 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, which is prone to headaches.

2. Reduce 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 people with low blood pressure lower, which will cause headache, which is called intracranial hypertension or hypotensive headache in medicine.

3, hypoglycemia headache

In summer, people often have headaches because of poor sleep, weak spleen and stomach, and loss of appetite. This kind of headache is caused by malnutrition and low blood sugar in the camp, which leads to the lack of necessary energy in the brain and headache.
