We think about sex. We fantasize about sex. We spend an inordinate amount of time and money in the pursuit of sex. We have sex. What’s more. Studies have shown that sex is extremely beneficial to our health. Sex activates a variety of neurotransmitters that impact not only our brains but several other organs in our bodies.
Why Is Sex Important?

1. Sex Helps You Sleep 

Experts say while there isn’t enough solid clinical proof to suggest that sex makes you sleepy, the basic underlying mechanics of the chemicals released during sex may help one sleep better. Among other things, it has a lot to do with the hormone oxytocin, nickname “the love hormone.”


2. Sex Makes You Look Younger 

Michael Roizen, MD, would say that sex is keeping Kranz young. In his best-selling book, RealAge -- Are You as Young as You Can Be?, Roizen makes the case for the antiaging effects of sex after surveying the available literature. "Having sex at least twice a week can make your RealAge 1.6 years younger than if you had sex only once a week," Roizen says. He defines 'real age' as "an estimation of your age in biologic terms, not chronologic years."

3. Sex Relieve Migraines 

Sex may relieve migraine pain for some people who suffer from the intense headaches, new research suggests.
The finding, published in the March issue of the journal Cephalalgia, found that sexual activity relieved the pain of migraines or cluster headaches, severe, one-sided recurring head pains, for up to a third of patients. Some of the patients even reported using sex as a kind of headache therapy.


4. Sex Can Help You Lose Weight 

Men burned on average 101 calories and women 69 calories when they had sex. The average intensity was higher than walking but lower than jogging, Prof. Karelis explains, putting it firmly in the category of moderate-intensity exercise.


5. Sex Boosts Your Immune System 

It's true that some research has shown that people who say they have frequent sex — once or twice a week — have higher levels of immunoglobulin, molecules produced by white blood cells that are a critical part of the immune response, according to a study published in Psychological Reports.


6. Sex Reduces Prostate Cancer Risk 

The researchers found that men who ejaculate more frequently than a typical man can reduce their risk of prostate cancer by up to 33 percent. According to the study, the optimal frequency of ejaculation is 21 times per month.

7. Sex Reduces Heart Attack Risk

Reporting in the American Journal of Cardiology, researchers say they've found that men with a low frequency of sexual activity have an increased risk of cardiovascular disease.
Men who reported sexual activity of once a month or less had a higher risk of cardiovascular disease than men who reported having sex twice a week or more, writes study researcher Susan A. Hall, PhD, of the department of epidemiology at the New England Research Institutes.
