According to the NHS Direct website, "sexercise" can lower the risk of heart attacks and helps people live longer.
Endorphins released during orgasm stimulate immune system cells, which also helps target illnesses like cancer, as well as wrinkles, it states.
"Forget about jogging round the block or struggling with sit-ups.
"Sex uses every muscle group, gets the heart and lungs working hard, and burns about 300 calories an hour."
The advice suggests "regular romps this winter" could lead to a better body and a younger look.
Increased production of endorphins "will make your hair shine and your skin smooth," it adds.
"If you're worried about wrinkles - orgasms even help prevent frown lines from deepening."
