Have more sex

Although regular sex has long been known to improve selfesteem and combat stress, leading to a longer, happier life, there may be many more healthy reasons to dim the lights and move to the bedroom.

During an orgasm, the body produces the hormone oxytocin, which battles against insomnia, encouraging a more restful night’s sleep, and improves intimacy and bonding within a relationship (oxytocin is also released when women give birth as part of the mother-baby bonding process).

Studies in which couples were asked to go without sex for a period of months found that the strength of their relationships generally declined rapidly.

Oxytocin has also been linked with pain relief, and the endorphins released during sex add to this painkilling effect: there are rafts of evidence suggesting that sex can soothe everything from PMS to lower back pain.

Having sex once or twice a week can also boost your immunity to disease, because it is linked with higher levels of a natural antibody, immunoglobulin A (IGA), which can protect you from contracting colds and other infections.

Also, according to a report in the British Journal of Urology, men who ejaculate frequently when aged in their 20s, reduce the risk of getting prostate cancer by one-third.

All this and it is a pretty good way to work out, too.
