Roommates shouldn't do that

summary

We should all be sensitive to the word "sex" in our life, right? It is inevitable for couples and couples to meet roommates. So of course we need to understand what we can't do after sex. Let's introduce some related knowledge.

Roommates shouldn't do that

First: men do not immediately urinate, urinate in time after sex, is conducive to flushing the urethra, to avoid infection. For women, immediate urination is a simple and effective way to prevent urinary tract infection. Because the female urethra is short and straight, the bacteria of vulva may retrograde into the urethra during sexual life, causing urethritis, cystitis, etc. However, experts say that men should not rush to urinate after sex, otherwise it will cause damage to the prostate, because men's urethra is long and curved, and the resistance of urine passing is large and the time is long. Sexual life has just ended, the corpus cavernosum congestion has not yet subsided, and the contraction of urethral sphincter and detrusor has not been eliminated, which causes high urethral resistance, leading to dysuria, or even urination. At this time, if you are in a hurry to urinate, it will increase the pressure in the urethra, and the urine with bacteria and metabolic waste will flow back into the prostate. For a long time, it is easy to cause prostatitis. Experts suggest that men should rest for 5-10 minutes after ejaculation and urinate after the hyperemia disappears. Need to remind is, if after sex appear frequent urination, urgency, pain and other symptoms, may be urinary system infection, should be timely to the hospital.

Second: can't immediately sleep, men in the sex life, generally feel tired, therefore, many people like to fall asleep, think that this can eliminate fatigue. In fact, the opposite is true, which will make the fatigue after ejaculation last until the next day. Usually, when couples have sex, from the beginning of sexual excitement to the end of orgasm, under normal circumstances, the duration is about 5-20 minutes, there are also longer than this. During sexual life, human sympathetic nerve is in a state of high tension, and the secretion of various hormones, especially sex hormones, is exuberant. At this time, not only the sexual organs of both sides are in a state of high hyperemia, but also many tissues of the body participate in this special physiological process from the period of sexual excitement to climax, such as: faster heartbeat, higher blood pressure, faster breathing, skin vasodilation, increased perspiration and so on. Therefore, in this process, the body's energy consumption is significantly increased, and the metabolism is enhanced. The reason why they feel tired after sex is mostly due to the relaxation of the reflex function of the brain and spinal cord which controls the ejaculation. During ejaculation, the nerves are excited and tense, and the nerves and spinal reflex nerves are relaxed after ejaculation. Young people are sensitive and active, so they recover quickly, and some even recover immediately. Elderly people have a slow nerve reaction and a relatively long recovery time. If they fall asleep immediately after ejaculation, the reflex function causing fatigue will continue to relax, and the fatigue will hardly disappear. If you don't go to bed immediately after sex, you can get up and continue to do something in daily life, which can make the reflex nerve become dull due to sexual stimulation recover smoothly. If you go back to sleep immediately after the event, the dull effect of sleep plus the dull effect of sexual stimulation will make you tired until the next day, making your back ache.

Third: people often feel hot and thirsty and eat cold food, which has no adverse effect on the reproductive system. Because the changes caused by sexual excitement only focus on the sensory nervous system and endocrine system, with the disappearance of sexual excitement, this change will slowly return to normal. Eating something cool, even if stimulating, is not limited to the digestive tract. But, because in sexual life, because sympathetic nerve is more excited, compared with usual, gastrointestinal blood will also be reduced. Therefore, before the gastrointestinal mucosal congestion returns to normal, drinking ice water immediately will make the gastrointestinal mucosa suddenly cold, causing certain damage to the gastrointestinal tract. In severe cases, it may also cause gastrointestinal discomfort or colic. Whether it's summer or winter. Experts suggest that if you feel thirsty after sex, you may as well drink a small amount of warm water or cold boiled water, and try not to drink ice water or ice drinks. As for those who originally suffered from gastroenteritis, dyspepsia, ulcers, even if they do not have sex, eating more cold food is not good. It can be seen that eating ice-cream, popsicle and so on, no matter whether they have sex or not, should be based on their own gastrointestinal function, not unrestrained to eat.

matters needing attention

Can't immediately blow, after sex life is likely to be covered with sweat, men like to directly naked to air conditioning blowing, this is also wrong, so it's easy to let bacteria have a chance. After sex, the body's ability to regulate body temperature will be weakened, vulnerable to cold. In addition, if the cold wind directly causes the sweat glands to drain away * suddenly, the sweat can not be drained. Therefore, even in the heat, it is necessary to avoid blowing cold air to the air conditioner without wearing clothes, and cover it with a thin quilt.
