It could be time to sideline that expensive eye-cream, because sex glow is a real thing. Orgasm triggers the release of oxytocin, more fondly known as the ‘love hormone’, which helps ease the stress hormone cortisol.

When these levels dip, so do those signs of skin inflammation, making eczema, pimples and blemishes less noticeable. Plus, an increase in dehydroepiandrosterone levels will keep hair shiny and skin bright.

The rush that follows an orgasm releases a hormone called prolactin, which helps stem cells in the brain develop new neurons in the olfactory bulb or smell centre.

While you can achieve an enhanced schnoz from self-service, a recent study found that a bed buddy increases prolactin release by 400 per cent.

A study of over 1,800 US women found that a whopping 32 percent used masturbation as a tool to help fall asleep.

This is because climax sparks the release of a chemical cocktail made of oxytocin, prolactin and vasopressin, all of which are hormones that actually induce that content and sleepy feeling.

While it isn’t imperative to the success of conceiving, scientific evidence suggests that the uterine contractions associated with climax can actually assist sperm on its journey to fertilising an egg.

A small-scale study from the University College Cork has found the chances of falling pregnant to be 10-15 percent higher in women who reach the big ‘O’, compared to those who don’t.

While it’s obvious that the act of sex with a partner would indeed help burn calories (207 per 30 minutes to be exact), reaching climax has also been found to curb appetite.

A study with mice found the release of oxytocin that follows an orgasm can help shift motivational behaviour from a desire to snack, to a desire to reproduce.
