During sexual intercourse, the blood vessels around the body are congested and expanded, and the sweat gland pores are open to perspire. At this time, when the cool breeze blows, the blood vessels in the skin will suddenly shrink, causing a large amount of blood to flow back to the heart. It increases the burden on the heart; at the same time, it can also cause the sweat gland excretion pores to suddenly close, causing sweat to stay in the sweat glands, which is not conducive to perspiration and makes it easy to catch a cold.

Secondly, after heavy sweating in summer, blood viscosity increases, blood supply to the brain decreases, and oxygen supply is insufficient. If you enter a room with a lower temperature at this time, the blood vessels will constrict and the brain will be severely deprived of oxygen, making you particularly prone to fatigue after sex.

In addition, if you stay in an air-conditioned room all day long, it will be difficult for the air to circulate and a lot of bacteria will accumulate in the room. When the human body is tired and sweating, its resistance will decrease and it will also be susceptible to other diseases.

Of course, it is not good to have sex in a hot environment without turning on the air conditioner. It is best to use conditioner before sex. Turn on the air conditioner half an hour in advance to lower the room temperature, and keep the difference between the indoor temperature and the outdoor temperature at about 5-10 degrees. It is best to open windows for ventilation or turn on an electric fan to cool down before starting sex.

If you are already sweating profusely before having sex, you should wait until the sweat has completely dried and your heartbeat is stable before having sex, otherwise it will easily lead to collapse. If you find that you have a lot of abnormal sweating after sexual intercourse, it may be a sign of physical weakness. It is best to go to the hospital for examination in time and adjust your lifestyle.
