Why do boys smoke after sex?

Some boys like to smoke a cigarette after sex, which is a psychological process of feeling unsatisfied. However, they do not know that smoking after sex is harmful to health because the blood circulation and metabolism of the body are faster at this time. Smoking at this time will cause some harmful substances in the smoke to quickly enter the blood. The most obvious harm is that it affects sexual function and damages the gastrointestinal mucosa.

Three things you are forbidden to do after sex

1. Smoking after sex affects sexual function

Many people always like to lie down on the bed and smoke after sex, which is extremely unhealthy. After sex, the blood circulation increases, and nicotine is quickly absorbed into the blood, making people excited and their heads feel light-headed, just like the feeling described by "smokers" as "a cigarette after sex, happy as a god".

In fact, smoking one cigarette after sex is more harmful than smoking ten cigarettes normally, and it is even the main cause of impotence. Because after sex, all systems of the human body are in a state of relaxation. At this time, the nicotine in tobacco can directly stimulate the sympathetic ganglia and indirectly stimulate the adrenal medulla to release adrenaline, causing small arteries to contract, which can reduce arterial blood flow during erection. Long-term smoking after sex can also cause arterial atherosclerosis, which can affect arterial blood flow. Reduced arterial blood flow cannot induce a full erection.

2. Drinking cold drinks to quench thirst can damage the gastrointestinal mucosa

During sexual intercourse, blood circulation in the body speeds up, and after sexual intercourse, people will feel hot and thirsty. Some people are eager to drink cold drinks or take cold showers to remove sweat, which is not good for health.

During sexual intercourse, the blood vessels in the gastrointestinal tract are in a state of expansion. Before the congestion of the gastrointestinal mucosa returns to normal, consuming cold drinks will cause the gastrointestinal mucosa to be suddenly exposed to the cold and suffer certain damage, and even cause gastrointestinal discomfort or colic.

3. Turn on the air conditioner when you sweat to reduce your resistance

A cold environment is not the best environment for sex. First of all, during sexual intercourse, blood vessels throughout the body are congested and dilated, and the pores of the sweat glands are open to sweat. At this time, when the cool breeze blows, the blood vessels in the skin will suddenly contract, causing a large amount of blood to flow back to the heart, increasing the burden on the heart; at the same time, it will cause the sweat gland excretion pores to suddenly close, causing sweat to stagnate in the sweat glands, which is not conducive to sweating and is easy to catch a cold.

Secondly, after sweating a lot in the summer, the blood viscosity increases, the blood supply to the brain decreases, and the oxygen supply is insufficient. At this time, if you enter a room with a lower temperature, the blood vessels will contract, the brain will be severely hypoxic, and you will be particularly prone to fatigue after sex.

In addition, if you stay in an air-conditioned room all day, the air will not circulate well and many bacteria will accumulate in the room. When the human body is tired and sweating, the resistance will decrease and it will be easy to get infected with other diseases. Of course, it is not good to have sex in a hot environment without turning on the air conditioner.
