Many men, after intimacy with their beloved, begin to fall asleep. There are a number of reasons for such pleasant fatigue. In most cases, this is a combination of the expenditure of a large amount of physical energy during sexual intercourse, as well as chemicals, the release of which accompanies the completion of the act, i.e. orgasm. At the same time, not all men feel tired after sex – for some, after intimacy with a loved one, a feeling of pleasant relaxation appears. Estet-portal.com will explain why some men feel sleepy after sex.
Hormons and neurotransmitters are to blame for the fact that you want to sleep after sex
It is well known that during sexual intercourse a number of chemical reactions take place in the body. During orgasm, the process of release of various hormones is activated, which as a result leads to the fact that after sex you want to sleep, namely:
1. Prolactin
This hormone is associated with feelings of sexual satisfaction. One of the main reasons a man feels tired after sex is the fact that prolactin makes a man sleepy. The level of this hormone rises during sleep. And until the level of prolactin decreases, the man will not be ready for a second act.
Prolactin levels after orgasm during sex are 4 times higher than after masturbation.
2. Oxytocin
This hormone helps to strengthen the connection between partners, as well as love, trust and social looseness. A pleasant feeling of relaxation overshadows all worries and anxieties, which is just the perfect condition for sleep.
3. Vasopressin
Vasopressin helps blood vessels constrict, and it also controls fluid retention in the body. Thanks to vasopressin, the body manages to maintain homeostasis, and ADH increases the ability to deal with stress and strengthen bonds. The release of this hormone into the brain (along with oxytocin) helps to increase feelings of relaxation.
4. Neurotransmitters
During ejaculation, among other things, the brain also receives a dose of norepinephrine, serotonin and nitric oxide (NO). This combination of neurotransmitters also contributes to relaxation, in particular, serotonin calms both the body and the brain, and nitric oxide is mainly responsible for the relaxation of the entire penis.
5. Parasympathetic nervous system
After sex, the sympathetic nervous system rests and turns over the reins to the parasympathetic nervous system, which stimulates physical relaxation, blood flow to the limbs, and calmness.
6. Physical activity
Not always, but in most cases, men do more physical work during sex than women. And the longer the sexual intercourse, the more the man spends energy, and the more he gets tired.
7. Nighttime
The obvious answer to the question of why you feel sleepy after sex is the fact that people most often resort to this pleasant pastime in the late evening or at night. The body is already preparing for sleep by changing the balance of chemicals in the brain and the whole body. And after an orgasm, there are even more substances that contribute to a sound and healthy sleep. That is why sex is considered one of the best cures for insomnia.
The release of hormones and neurotransmitters during orgasm contributes to sound and healthy sleep.
There is a theory that the reason why men (and sometimes women) feel sleepy after sex is due to natural evolutionary processes. So, one of the hypotheses is that men tend to sleep after intercourse, so that he does not have a desire to continue the fun with another partner. Psychologists, on the other hand, reassure women that men who are happy with their beloved and are aimed at long-term relationships fall asleep after sex very quickly due to the action of the hormones of love and affection. In any case, estet-portal.com is convinced that drowsiness after sex – not a sign of disrespect for a loved one, but the result of complex chemical processes and evolutionary mechanisms.
