Modern white-collar workers pay attention to health and health care. They go to the gym to exercise whenever they have free time. Sometimes couples will go to exercise together. This behavior is good, but everyone misses the best gym, which is the warm "bed". As everyone knows, sex is the most effective, happiest, and most comfortable exercise. Adhering to a moderate, reasonable and healthy sex life can help couples have a strong body.

I am very happy in the quilt on the bed

A survey by the National Institute of Economic Research found that if married people have regular sex, the happiness it brings is the same as earning an extra $100,000 a year.

Sex is good for human health

Researchers from Wilkes University in the United States analyzed 111 volunteers aged 16 to 23 and found that having sex once or twice a week can increase the amount of type A immune globulin in the body by 30%, thereby increasing immunity, helping people prevent colds and flu.

Sex makes people more cheerful

Semen contains nutrients such as zinc, calcium, and protein, which are of great benefit to the female body. Moreover, a study by New York University in the United States also found that women who do not use condoms during sex are more cheerful and less likely to be depressed. However, the researchers also stressed that this result only applies to committed partners.

Scientific sex improves sperm quality

Australian researchers conducted an experiment on 118 men with sperm quality problems, allowing them to enjoy sex seven days a week. As a result, 81% of the people had a significant reduction in the number of "bad sperm".

Researchers believe that regular sex can help sperm "replace the old and bring out the new", thus improving its quality. After orgasm, the body secretes a hormone called oxytocin, which makes people feel warm and intoxicated.

Sex also promotes the release of endorphins, a natural sedative that makes people feel relaxed and easier to fall asleep. These two chemicals particularly affect men.

Research from the Royal Edinburgh Hospital in Scotland found that sex can make women look 12 years younger. In the study, men were asked to look in a mirror and evaluate a woman on the other side. Women rated as "very young" had sex an average of four times a week.

This is no coincidence! Because studies have long found that sex can promote estrogen secretion, making skin smoother and hair shiny.

Scientific sex protects heart function

This may be the good news that men have been waiting for: A British study found that people who enjoy sex at least twice a week can reduce the risk of heart disease by half compared with those who enjoy sex less than once a month. .

The oxytocin released during orgasm not only improves your mood, but also makes you feel closer to your partner, especially for women. In fact, not only sex, but also touching or foreplay can cause a large amount of oxytocin to be released.

30 minutes of sex can consume 85 to 200 calories. It depends on your level of commitment. Sex can exercise muscles in the abdomen, thighs, arms, etc. You can achieve the same results as in the gym without leaving home and spending a penny, so why not?
