In high temperature weather, both the skin and the blood vessels of the human body are subject to the physical laws of thermal expansion and contraction, and the blood vessels are in a state of dilation.

It is better to drink warm water than cold water to cool down the heat< /p>
Drinking water is a physiological requirement when people sweat a lot to dissipate heat.
The reason why people feel cool after drinking ice water is mainly because the ice water reduces the temperature of the mouth, but other parts of the body do not significantly cool down.
At the same time, the ice water will also slow down the blood circulation in the body, which is not conducive to the evaporation of sweat.
And warm water can promote blood circulation, speed up the evaporation of sweat and heat loss, can better reduce the temperature of the whole body, and can achieve the effect of cooling down.
