For many male friends nowadays, they often fall asleep after sex, which not only affects their physical health but also fails to take into account the feelings of their partner. Actually, this is also caused by physical fatigue. Let's take a look together!
Usually, during sexual activity, couples start with sexual excitement and end with orgasm. Normally, the duration is approximately 5-20 minutes, but there are also longer ones. During sexual activity, the sympathetic nervous system of the human body is in a highly tense state, and various hormones, especially sexual hormones, are secreted vigorously.
At this point, not only are the sexual organs of both parties in a highly congested state, but many tissues of the body also participate in this special physiological process from the sexual excitement period to the climax period, such as accelerated heartbeat, increased blood pressure, accelerated breathing, systemic skin vascular dilation, and increased sweating. Therefore, during this process, the body's energy consumption significantly increases and metabolism enhances.
The reason for fatigue after sexual activity is mostly due to the relaxation of the reflex function of the brain and spinal cord that controls the discharge of semen after ejaculation. During ejaculation, the nerves are excited and tense, and after ejaculation, the nerves and spinal cord reflex nerves relax.
Young people have sensitive and active nerves, so they recover quickly, and some even recover immediately. Older people have sluggish neural responses and a relatively long recovery time. If they fall asleep immediately after ejaculation, the reflex function that causes fatigue will continue to relax, making it difficult for fatigue to disappear.
After sexual intercourse, do not go to bed immediately. Getting up and continuing to do some daily tasks can help smooth the recovery of reflex nerves that have become dull due to sexual stimulation. If you immediately fall asleep after completing a task, the dull effect of sleep combined with the dull effect of sexual stimulation will cause fatigue to continue until the next day, making your back ache.
So, after sexual intercourse, remember not to immediately turn around and go to sleep; Watching TV for a while, getting up to drink a glass of water, or having a romantic conversation with a woman for a while before going to bed, won't make fatigue last until the next day.
