Sex Reduces Pain

As the hormone oxytocin surges, endorphins increase, and pain declines. So if your headache, arthritis pain, or PMS symptoms seem to improve after sex, you can thank those higher oxytocin levels.
In a study published in the Bulletin of Experimental Biology and Medicine, 48 volunteers who inhaled oxytocin vapor and then had their fingers pricked lowered their pain threshold by more than half.

Sex Boosts Self-Esteem

Sex Boosts Self-Esteem

Boosting self-esteem was one of 237 reasons people have sex, collected by University of Texas researchers and published in the Archives of Sexual Behavior.
That finding makes sense to Gina Ogden, PhD, a sex therapist and marriage and family therapist in Cambridge, Mass., although she finds that those who already have self-esteem say they sometimes have sex to feel even better. "One of the reasons people say they have sex is to feel good about themselves," she tells WebMD. "Great sex begins with self-esteem, and it raises it. If the sex is loving, connected, and what you want, it raises it."

Sex Improves Intimacy

Having sex and orgasms increases levels of the hormone oxytocin, the so-called love hormone, which helps us bond and build trust. Researchers from the University of Pittsburgh and the University of North Carolina evaluated 59 premenopausal women before and after warm contact with their husbands and partners ending with hugs. They found that the more contact, the higher the oxytocin levels.

Sex improves intimacy

"Oxytocin allows us to feel the urge to nurture and to bond,".
Higher oxytocin has also been linked with a feeling of generosity. So if you're feeling suddenly more generous toward your partner than usual, credit the love hormone.

Sex Relieves Stress

A big health benefit of sex is lower blood pressure and overall stress reduction, according to researchers from Scotland who reported their findings in the journal Biological Psychology. They studied 24 women and 22 men who kept records of their sexual activity. Then the researchers subjected them to stressful situations -- such as speaking in public and doing verbal arithmetic -- and noted their blood pressure response to stress.
Those who had intercourse had better responses to stress than those who engaged in other sexual behaviors or abstained.

Another study published in the same journal found that frequent intercourse was associated with lower diastolic blood pressure in cohabiting participants. Yet other research found a link between partner hugs and lower blood pressure in women.
