Why is it so hot that people have headaches?

In hot weather, besides heatstroke, many people have headache symptoms inexplicably. In fact, this is probably due to the following two factors:

1. When the weather is hot, people's mental state is very important. If they are in an excited state, people are more likely to endure the hot weather, or even feel nothing. However, if they are depressed, depressed, etc., they are easily restless and bored. Some people sleep less at night, or are tired and lack of rest, so in hot days, it is easy to have a headache when they walk outside for a long time.

2. Sweating more makes the effective circulating blood of the whole body decrease, the heart rate increases, the blood pressure increases, and the brain nervous system is in a state of excitement (this excitement is different from the emotional excitement in the first article). This state of excitement is not a problem for a short time, but it lasts too long. Headache is very easy, and it seems to burst. In this regard, the treatment methods are as follows:

(1) Drinking some cool drinks or tea can quickly relieve psychological pressure, replenish blood flow, lower blood pressure and relieve headache.

(2) If the effect is not obvious after drinking water, the head still hurts badly, so sleep is adopted to stop the hyperactivity of the brain and turn it into inhibition.
