1. Sex strengthens the immune system
Microbiologist and writer William Kolbe believes that this occurs due to the impact of sex on the pituitary gland.
During sexual activity, signals to stimulate the endocrine axis, including the thymus gland, which plays an important role in the functioning of the immune system, reach the pituitary gland.
According to a study published in 2009, those who have sex once or twice a week have 30% higher levels of Immunoglobulin A in saliva than those who abstain from physical intimacy Sexual frequency and salivary Immunoglobulin A. . Immunoglobulin A is an antibody that helps us fight infections, including colds. The highest levels of these antibodies were found in couples who make love several times a week.
2. Sex lowers blood pressure
In 2000, scientists learned from 51 participants (men and women) aged 20 to 47 about how often they engage in sex, and then measured their blood pressure. It turned out that a higher frequency of sexual activity is associated with lower blood pressure A preliminary report relating frequency of vaginal intercourse to heart rate variability, Valsalva ratio, blood pressure, and cohabitation status. .
Sex is an excellent workout for the heart and blood vessels, which positively affects blood pressure. Moreover, active production of sex hormones, especially estrogen, is very beneficial for the heart.
3. Sex promotes heart health
In a study conducted by scientists from the University of Bristol, it was found that regular sexual activity reduces the risk of stroke and coronary insufficiency in men Sexual intercourse and risk of ischaemic stroke and coronary heart disease: the Caerphilly study. .
American researchers reached similar conclusions. According to their data, men who are sexually active once a month or less have a higher risk of developing cardiovascular diseases compared to those who have sex twice a week or more Sexual Activity, Erectile Dysfunction, and Incident Cardiovascular Events. . Researchers suggested that those who regularly engage in sex have close trusting relationships in their couple. This positively affects health, including reducing stress levels.
4. Sex reduces stress levels
Relaxation and a good mood after sex is a common occurrence. According to a study published in 2002, semen has antidepressant properties Does semen have antidepressant properties? . Contact with semen during sex increases feelings of happiness in women, thereby reducing stress levels.
Keri Simon, a clinical social worker from St. Louis, also believes that close trusting relationships reduce the production of the stress hormone cortisol.
Through touch and intimate gestures, we signal that we can be trusted, calming the body's natural fight or flight response. Communication through touch is very important. With a simple handshake, a pat on the back, or a hug, we feel a connection with another person.
5. Sex improves sleep
Many often fall asleep right after sex. This is because during lovemaking and right at the moment of orgasm, endorphins and the hormone oxytocin are released, which stimulate falling asleep. Endorphins are produced in the pituitary gland during intense physical exertion, stress, and orgasm. Oxytocin is also called the love hormone because it is usually released when two people come into physical contact.
Interestingly, a study conducted in 2014 found that women in romantic relationships who slept an hour longer had an increased level of sexual desire The impact of sleep on female sexual response and behavior. . They were also 14% more likely to engage in sex the next day. So the connection between sex and falling asleep apparently works both ways.
