Researchers have revealed several benefits that regular sexual activity has on the body, and they are more active during summer.
Researchers in Boston found that testosterone level in summer doubles as sunlight stimulates the production of vitamin D, which releases sex hormones, writes dailymail.co.uk.
It is known that sex helps to burn calories, but experts have revealed other benefits that sexual activity brings to the body.
Sex is a good way of testing the vision
Sex relaxes muscles and reduces tension in shoulders and neck. Surprisingly, the sex can tell if a person does or doesn’t need glasses.
“We had patients who complained of vision problems after sex. Like any muscle in the body, the eyes were relaxed and worked at their real ability”, says doctor Arun Ghosh, a specialist in sexuality at Spire Hospital Liverpool.
Sex protects against heart disease
A study conducted at Queen University in Belfast found that sexual activity three times a week can halve the risk of heart attack. Another study says that women who have orgasms twice a week had a risk of developing heart disease 30% lower than those who did not have sex or orgasm.
“Endorphins released during sex neutralize stress hormones in the body that are related to heart disease”, said Lisa Turner, sexual therapist. However, what increases the risk of heart attacks is extramarital relations.
Sex strengthens the bones
Studies have shown that postmenopausal women who have sex every week have estrogen levels two times higher than those who do not have sex. The hormone has a beneficial role for bone health and its absence after menopause may be related to osteoporosis.
Sex increases fertility
Sperm quality increases with the number of sexual acts that for a man. For someone who wants to conceive a child, sexual relations are often beneficial.
Sex decreases the risk of prostate cancer
Researchers at the University of Nottingham found that men over 50 years who have a regular sex life are at a 50% lower risk of developing prostate cancer.
Sex helps quit smoking
Men can more easily give up smoking if they know that this usually leads to the shrink of sexual organ and may cause sexual impotence.
Smoking is a known cause of erectile dysfunction because it makes blood flow more difficult. A study of 7,000 men in China shows that the risk of impotence is higher as the number of cigarettes smoked daily increased.
Sex is a natural sleeping pill
For a man, a powerful orgasm is the equivalent to 2-3 mg of diazepam or Valium. “Diazepam relaxes muscles, and this is why so many men feel sleepy after sex”, says doctor Ghosh.
