Does smoking after sex affect sexual function? Under what circumstances is cohabitation prohibited

In fact, there are many preventive measures in marital life. If they don't pay attention, every minute may affect their health, and even damage their health. 1. Smoking afterwards can affect sexual function. Many people like to lie by the bed and smoke after sex, which is extremely unhealthy. Because after sexual intercourse, the amount of blood circulation increases, and nicotine is quickly absorbed into the bloodstream, causing people to be in an excited state and their heads to float, just like "smokers" describing the feeling of "a cigarette afterwards, happiness like a fairy". In fact, smoking one cigarette after sex is more harmful than smoking ten cigarettes, and even the main cause of impotence. Because after sex, all systems of the human body are in a relaxed state. At this time, the nicotine in tobacco can directly stimulate the sympathetic ganglia and indirectly stimulate the adrenal medulla to release adrenaline in the human body, making the small arteries contract, which can reduce the flow of arterial blood during erection. The atherosclerosis caused by smoking after long-term sex can also affect the arterial blood flow. The arterial blood flow is reduced, which cannot induce full erection. In addition, after sexual intercourse, the blood in the sponge quickly flows back. At this point, smoking not only reduces arterial blood flow, but also disrupts the venous flow limiting mechanism during erection, which over time can affect sexual function and even lead to impotence. 2. Turning on the air conditioning when sweating and reducing resistance to cold environments is not the best sexual environment. Firstly, during sexual intercourse, blood vessels throughout the body become congested and dilated, with sweat glands and pores in an open and sweating state. When a cold wind blows, skin blood vessels suddenly contract, causing a large amount of blood to flow back to the heart, increasing the burden on the heart; It can also cause sudden closure of sweat gland excretion pores, causing sweat glands to remain stagnant, which is not conducive to sweating and is also prone to catching a cold. Secondly, after sweating heavily in summer, blood viscosity increases, blood supply to the brain decreases, and oxygen supply is insufficient. At this point, if you enter a low-temperature room, blood vessels constrict, the brain is severely hypoxic, and it is particularly prone to fatigue. In addition, if you stay in an air-conditioned room all day, the air is difficult to circulate, and a lot of bacteria will accumulate in the room. When the human body is fatigued and sweating, its resistance will decrease and it is also prone to contracting other diseases. Of course, not turning on the air conditioning or having sex in a hot environment is not good. It is best to use air conditioning before sexual intercourse. Turn on the air conditioning half an hour in advance to reduce the indoor temperature and maintain a difference of 5-10 ℃ between the indoor and outdoor temperatures. Before starting sexual intercourse, it is best to open windows for ventilation or turn on electric fans for cooling. If you sweat before traveling, you should wait until the sweat is completely dry and your heart rate stabilizes, otherwise it can easily lead to collapse. If you notice many abnormal sweating after sexual intercourse, it may be a sign of physical weakness. It is best to go to the hospital for examination in a timely manner and adjust your lifestyle.
