The reason for dizziness and sleepiness after intercourse

Most of the time, couples feel sleepy after sex, why does this not happen normally and it happens after intimacy!

For many women, one of the annoying facts of life is the relationship between sex and men snoring. Men seem to get sleepy after intercourse, no matter what time of day it occurs. Although women sometimes feel sleepy after sex, this phenomenon is more obvious in men, but what is the reason for this sleepiness in men?
The first reason is related to the time of intercourse, which is usually done at night in bed and requires physical activity that leads to fatigue, and men usually need to do more physical activity than women during intercourse, although this is not always the case. So when intercourse is over, it’s normal for men to feel sleepy.
Second, researches using “positron emission tomography” (PET) scans have shown that a main condition for reaching orgasm is to let go of one’s fears and anxieties. Self-intercourse also induces muscle relaxation, which may make the process of falling asleep easier.
Also, the brain biochemistry of orgasm is probably also involved in this process. Research shows that during ejaculation, a series of chemicals are released in the male brain, including norepinephrine, serotonin, oxytocin, vasopressin, nitric oxide (NO) and the hormone prolactin. The release of prolactin in the brain is associated with the feeling of sexual satisfaction and also plays a role in the “recovery time” or “resistance period” (the period when a man is unable to be aroused after reaching orgasm). Studies have also shown that men who lack prolactin have a shorter recovery time and are able to get aroused sooner. Prolactin levels are naturally higher during sleep, and injecting animals with this hormone makes them feel instantly tired. These findings indicate a strong relationship between prolactin and sleep. Therefore, the release of this hormone during orgasm may also be involved in men’s sleepiness.
Oxytocin and vasopressin, two other hormones and neurotransmitters released during orgasm, are also associated with sleep. The release of these hormones is often accompanied by the release of melatonin, the main hormone that regulates our body clock. It is also thought that oxytocin reduces the amount of stress, which will lead to relaxation and sleepiness, but what are the evolutionary reasons for this sleepiness after intercourse? From an evolutionary point of view, a man’s primary goal is to produce as many children as possible, and sleeping after intercourse does not help achieve this goal, but perhaps since a man is not able to be aroused for a while immediately after intercourse, sleeping helps him. to gain energy again and in this way make the best use of time. Although there is conflicting information about women becoming drowsy after sex, the woman will eventually sleep with the man (or use this time to care for the baby) and this is an evolutionary advantage for the man, i.e. When the man wakes up and is ready for intercourse again, the woman is by his side.
It is also possible that this sleepiness is simply a “side effect” of a more important evolutionary reason related to the release of oxytocin and vasopressin. In addition to being associated with sleep, these two hormones are involved in the “couple emotional bond” or social bonding that human couples often have. The release of these chemicals in the brain during orgasm increases the feeling of this emotional bond and trust between spouses and may partially explain the relationship between sexual intercourse and emotional bond. This emotional bond is beneficial for the couple to have children, because the cooperation of the two spouses in raising the child maximizes the probability of its survival.
However, there are many potential biochemical and evolutionary reasons for sleepiness after sex, some with direct effects and some with indirect effects, but no one has yet proven the exact cause of this phenomenon, but one thing is certain. : Women should deal with this phenomenon, because it doesn’t seem like this habit of men will change anytime soon, and if you are one of the women who are bothered by your husband’s snoring after intercourse, remember that your situation is not too bad. A recent survey of 10,000 British men showed that 48% of them fall asleep during intercourse!
