Some people have described s-x as one of the sweetest things on earth, and even if it is stressful and requires a lot of strength to do especially for men, it is a rigorous exercise many people would gladly undertake over and over again.
Though, it is no secret that many men nod off straight after s-x, some women also sometimes feel sleepy after s-x but the phenomenon seems more pronounced in men. To women, the obvious sign of complete ‘shutdown’ by men moments after a passionate encounter is practically frustrating, and could be accompanied with a loud buzz of snoring.
Scientists have given men the perfect excuse for feeling sleepy after s-x: ‘they just cannot help themselves, and not that they are just selfish.’ It is easy to think that men sleep off after s-x because they are tired, but findings have shown that it goes beyond that. Scientists have said that men really do need to sleep after s-x when they climax because their brains become flooded with sleep-inducing chemicals such as oxytocin, serotonin and prolactin. Also, the blood rush after the climax depletes the muscles of energy-producing glycogen and because men typically have higher muscle density than women, they become more tired after s-x.
In other words, the answer to the question, ‘why do men fall asleep after s-x’ may be as simple as saying that they have very little control over their bodies at that point; hence, it literally shuts down.
When a group of scientists led by a French Neuroscientist, Serge Stoleru, in a study scanned some men’s brains before and during orgasm, they found that the cerebral cortex, which is the ‘thinking’ area, shuts down almost immediately after orgasm. After this, two other areas, the cingulate cortex and amygdale direct the rest of the brain to deactivate from s-xual desire.
