What happens when a couple falls asleep right after sex?

After having sex, many people fall asleep immediately. Is this good or bad?

The body feels persistent fatigue after ejaculation, not because of excessive physical exertion during sex, but because the cerebrospinal reflex function that controls the excretion of semen relaxes for a period of time after ejaculation. If we want to eliminate this feeling of fatigue, we must re-excite the parasympathetic nervous system. If we fall asleep in a hurry at this time, we can only continue to relax the reflex function that causes fatigue, and then physical fatigue will occur on the second and third days.

Therefore, it is best not to fall asleep immediately after having sex. Doing some simple activities that can re-excite the nerves that are in a state of "relaxation and inhibition" will help your body recover, and you will be able to start your work and life energetically, easily and happily the next day.
