People enjoy eating hot food in the countries locating in hot regions of the world.
Eating hot food makes the body sweat and the body temperature will fall.
In hot summer, people usually relieve thirst with cold drinks, ice-cream, and cool watermelon.
However, eating cold food is not an effective way of heat relief because the body temperature rises again shortly after eating it.
When the body temperature rapidly falls, it quickly returns to normal, and it feels rather hot.
But when you eat hot food, your body temperature will be equal to the ambient temperature, and your circulation will be quickened so you will start sweating.
That is, the moisture evaporates and you will feel cool.
After a great deal of sweat, you should have a hot bath if possible.
As sweating expands your capillaries, a cold bath at this time will make your blood vessels contracted and the heat in the body cannot escape.
Thus, in hot summer, eating hot food and then having a hot bath can result in an unexpected heat-relieving effect.
