Sex may also play a fundamental role in preserving a happy marriage, according to research published in Psychological Science. Partners are suggested to experience a sexual "afterglow" that lasts for up to 48 hours following sexual intercourse. This afterglow is associated with higher levels of long-term relationship satisfaction.

Sex is also considered a significant form of exercise. Sex burns around 85 calories, or 3.6 calories per minute, according to a study published in PLOS One.

These few examples are a drop in the ocean of the numerous health benefits of sexual activity and masturbation that are presented in studies from around the globe. Medical News Today provide the low-down on the top evidence-based health benefits of sex.

1) Improves immunity

Participating in sex one to two times per week appears to be the optimum frequency to boost the immune system. Scientists can test how tough our immune systems are by measuring levels of an antibody called immunoglobulin A (IgA) in saliva and mucosal linings.
Study authors Carl Charnetski, from Wilkes University in Pennsylvania, and his colleague Frank Brennan found that people who had sex once or twice per week had a 30 percent increase in IgA. However, the same results were not seen in individuals who had sex more or less frequently.

Clifford Lowell, an immunologist at the University of California-San Francisco, says that people who are sexually active are exposed to more infectious agents than individuals who are not sexually active. The immune system responds to these infectious agents by producing more IgA, which may protect against colds and flu.


2) Good for the heart

Physical activities that exercise the heart are good for your health, and this includes sex. Being sexually aroused increases heart rate, with the number of beats per minute peaking during orgasm.
Men, in particular, have been shown to benefit from the effect of sex on the heart. A study published in the American Journal of Cardiology, involving men in their 50s, suggested that men who have sex at least twice per week have a 45 percent reduced risk of heart disease, compared with men who have sex less frequently.

3) Lowers blood pressure

Research conducted by Michigan State University and published in the Journal of Health and Social Behavior found that sex in later years might reduce the risk of high blood pressure - at least for women.

Women in the study aged between 57 and 85 years who found sex pleasurable or satisfying were less likely to have hypertension. However, male study participants who had sex once per week or more were twice as likely to experience heart problems than men who were sexually inactive.

In another study published in Behavioral Medicine, researchers found that the act of hugging can help a person to maintain a healthy blood pressure.

According to the American Heart Association, high blood pressure increases the risk of heart attack and stroke and can also affect your sex life. High blood pressure has an impact on blood flow throughout the body and can prevent enough blood flowing to the pelvis.

In men, high blood pressure can lead to erectile dysfunction and in women, high blood pressure can lower libido and reduce interest in sex. It is considered safe to have sex if you have high blood pressure. However, if you are concerned or are having problems in the bedroom, seek advice from your doctor.

4) Reduces the risk of prostate canc[/b]er

Men who frequently ejaculate could be protected against prostate cancer, the most common cancer among men in the United States.

Research led by Michael Leitzmann, from the National Cancer Institute in Bethesda, MD, and published in JAMA, discovered that men who ejaculated 21 times per month or more were a third less likely to develop prostate cancer than men who ejaculated between four and seven times per month.

[b]5) Relieves stress

Stress can cause all kinds of health problems, from headaches, problems sleeping, muscle tension, and upset stomach, to more severe conditions, including a weakened immune system and chronic depression.

Evidence published in Psychosomatic Medicine demonstrated that physical or emotional intimacy in couples is associated with reduced stress levels.

A study published in Biological Psychology found that people who engaged in penetrative sex experienced lower stress-related blood pressure when public speaking than individuals who had masturbated or had non-coital sex. Participants in the study who abstained from sex had the highest blood pressure levels triggered by stress.

Stuart Brody, a psychologist at the University of Paisley in the United Kingdom, hypothesized that the calming effect might be caused by the release of the "pair-bonding" hormone, oxytocin.

6) Boosts brain power

Research published in the Archives of Sexual Behavior suggests that frequent sex may improve women's memory. Results from a computerized word-memory task found that women who had penetrative sex had better memory recognition of abstract words.


Leitzmann and team have a number of theories as to why increased ejaculation may help to prevent prostate cancer.

The first theory is that frequent ejaculation may allow the prostate gland to clear out carcinogens, and materials that may orchestrate the development of carcinogens. Another theory suggests that regular drainage of prostate fluid stops crystalloid microcalcifications - which are associated with prostate cancer - from developing in the prostate duct.

Men who have more than 12 ejaculations per month may also benefit, although the researchers note that at this point, the research would not warrant recommending men to change their sexual behavior.
