One of the biggest criticisms and frequent fights between couples is what happens after a sexual relationship. It is very common that, after a sex session, men feel deeply sleepy and have difficulty staying awake, while many women seek to continue with hugs, cuddles or kisses afterwards. This contrast in reactions often generates discomfort and doubts: Why do men get sleepy after having sex? Next, we will explore in depth the reasons behind this phenomenon from a hormonal, biological and emotional perspective.
The science behind sleep after sex
Reaching climax involves a series of changes within the human body that go beyond mere pleasure. During orgasm, the brain releases several hormones and neurotransmitters that directly affect energy levels and emotional state. One of the main culprits of male lethargy is prolactin, a hormone whose secretion increases significantly after ejaculation.
La prolactin It is known for its role in the feeling of sexual satiety, as it signals to the brain that the body has fulfilled its reproductive function. For this reason, it has a significant sedative effect. Studies have also linked this hormone with decreased activity in the prefrontal cortex of the brain, which explains why men can feel so tired after sex.
In addition to prolactin, other chemicals such as oxytocin, known as the “love hormone,” and the Serotonin, responsible for regulating mood and sleep, contribute to this extreme relaxation. In men, these substances are combined with a sudden drop in energy due to ejaculation, which generates that feeling of immediate drowsiness.
Differences between men and women
While men tend to be exhausted and sleepy after sex, women often experience a more active or emotionally receptive state. According to research, this is due to hormonal and biological differences that exist between the sexes during and after climax.
In women, the release of vasopressin, another hormone involved in bonding, has a slightly different impact. This hormone encourages greater emotional connection and desires for intimacy, such as hugging, cuddling, or talking. So while men experience a physiological need to rest, women may feel the urge to strengthen the emotional bond.
Another key aspect is the multiorgasmic capacity Women have a much shorter or even non-existent refractory period (the time needed to regain sexual desire after orgasm), so they do not experience the same drop in energy as men. On the contrary, many women are ready to continue exploring their intimacy with their partner.
Physical and emotional factors
Sex involves not only emotional interaction, but also significant caloric and physical expenditure. A sex session can be compared to performing moderate exercise, since during sexual intercourse the heart rate and blood circulation increase. This activity can cause fatigue in those people who are not in the best physical condition or who have had a tiring day beforehand.
Furthermore, the emotional factors They also play a crucial role. Sexual intercourse with a trusted and loving partner often releases even more oxytocin, fostering a sense of security and relaxation. This combination of emotional and physical bonding can amplify the sleepy effect after intercourse.
Is it normal to feel sleepy after having sex?
Feeling sleepy after sex is completely normal, but it should not be an extreme or frequent symptom that interferes with daily life. In some cases, excessive fatigue could be a sign of other underlying health problems, such as dehydration, low blood sugar levels, or blood pressure disorders.
Furthermore, the postcoital dysphoria, which affects some people and manifests itself with negative emotions such as sadness or anxiety after sex, can be indicative of broader emotional or psychological problems. In these cases, it is advisable to seek professional help to understand the causes and how to manage them.
Tips to mitigate sleepiness after sex
- Choose the right moment: If you are prone to extreme fatigue after sex, avoid having sex right before bed or after strenuous work activities.
- Take care of your diet: Choose light meals before sexual intercourse and avoid excessive alcohol consumption, as this can amplify the drowsiness effect.
- Communication as a couple: Talk to your partner about these differences and how you can find a balance to meet both of your needs.
- Improve your physical condition: Performing cardiovascular exercises regularly will help you have more energy and physical endurance, which can reduce the feeling of post-coital fatigue.
Sleep after sex is a completely natural phenomenon that largely responds to the hormonal and biological processes of the human body. However, each person and each relationship is unique; the important thing is to maintain open communication with your partner so that both can fully enjoy intimacy and affection in all its forms.
