It's stuffy and humid.

First, the principle of human perspiration is that the body temperature is higher than the body surface temperature. Therefore, when the outside world is very hot and humid, sweat can not be discharged, which is easy to produce a sultry feeling. So you can raise your body temperature by physical means, such as simply running for two steps, doing exercise, or drinking some hot tea, hot water or hot soup to make your body sweat.

Second, find ways to reduce the body surface temperature. When it is sultry, if conditions permit, you can wipe your body with a hot and wet towel or take a hot bath at home. Taking a hot bath will be more conducive to sweating and heat dissipation. Of course, cold water bath can also reduce the body surface temperature, but the effect is short-lived.

Third, do a good job of indoor (home or office) sun protection. In summer, the temperature rises very quickly under direct sunlight, so try to avoid direct sunlight. When people are not there, close all the windows and pull the sun curtains tightly, and wait until people return to their rooms at night or when the sunshine is not strong.

Fourth, try to ventilate. Windy weather will not be sultry, so ventilation is the key to eliminate sultry. There are several ways to create air circulation. The first is to keep the window of the room facing, or turn on the exhaust fan. The second is to create wind power with the help of electric fans or hand fans; The third is to find a higher position or a tuyere to find the wind.

Fifth, peace of mind is naturally cool. If conditions don't allow physical cooling, try to keep calm and don't think about things you are worried about. It's best not to think about things and not to lose your temper. You should do some simple and easy work and keep a peaceful mind.

Sixth, have the common sense of self-help for heatstroke. In order to take preventive measures, if you have symptoms such as headache, dizziness, tinnitus, dizziness, thirst, palpitation and a slight increase in body temperature in the high temperature environment in summer, it means that you have heatstroke. Don't mistake it for a cold. Go to the shade in time to dissipate heat and take summer medicine.
