Why men feel sleepy after sex

There are several reasons why a man may feel sleepy after sex with his partner. One reason is that; 

Sex can be physically exhausting and especially if it is vigorous or prolonged, this can make the man to feel like they need to rest and regain energy.

This alone can cause fatigue and make you feel sleepy after having an intimate good time.

Another reason for the sleepiness is that, during sex the body releases hormones such as oxytocin (which is known as the “feel-good” hormone) and prolactin. These two hormones have a relaxing and sedating effect. It can help relieve stress and lower blood pressure. 

Also, during sex, the body also releases endorphins, which are chemicals that can help to relieve pain, promote feelings of well-being and boost happiness levels. The combination of these hormones can make a person feel very relaxed and sleepy.

Additionally, when a man orgasms during sex, the process can cause the body to release chemicals that can make you feel sleepy, such as melatonin and adenosine.

Finally, after sex, many people feel a sense of satisfaction and contentment, which can also contribute to feelings of sleepiness.
