Science reveals nine ways having sex benefits your health.
According to California-based obstetrician-gynaecologist Dr Sherry Ross, few things in life are better for people's hearts, bodies and souls than getting intimate between the sheets.
From burning calories to boosting the immune system and even fighting the signs of ageing, numerous studies reveal regular lovemaking seriously boosts people's wellbeing, reports the Daily Mail.
Sex is even a natural painkiller and could help combat insomnia, Dr Ross adds.
Below, Dr Ross outlines the nine ways, proven by science, being active between the sheets boosts people's health and wellbeing.
Researchers from the University of Quebec at Montreal analysed 21 heterosexual couples with an average age of 22.
Results revealed women burn, on average, 69.1 calories when they have sex for just under 25 minutes.
This calorie-burning number climbs higher still if you are on top, in a squat position or having an orgasm.
Dr Ross told NetDoctor: "The act of sexual intimacy can be a great workout and counts as such for many as their daily exercise regimen."
Boosts the immune system
A study by Indiana University found women with healthy sex lives produce higher levels of antibodies, which fight off infections.
Dr Ross said: "Regular sex makes for a stronger immune system, fighting off common illnesses such as colds and having less sick days from work.
"Sex also helps lower your blood pressure and lowers your risk of heart attacks."
For women suffering from urinary incontinence, which is common after childbirth, incorporating Kegel exercises into your sex life can strengthen your pelvic floor and improve bladder control, according to Dr Ross.
If this isn't enough, such exercises also heighten orgasms for both you and your partner, she adds.
Is a natural painkiller
Contracting genital muscles generate a pleasurable feeling that can reduce the discomfort of menstrual cramps, headaches and joint pain, according to Dr Ross.
She adds tracking your menstrual cycle and scheduling in an orgasm before your first period could prevent crippling discomfort.
After an orgasm, endorphins and the hormone prolactin are released, which relax the body and mind to promote sleep, Dr Ross claims.
Boosts pregnancy chances - even if you're not ovulating!
Researchers from the Kinsey Institute and Indiana University found women who have sex when not ovulating create an environment in their wombs that make it more hospitable for growing embryos.
This is due to orgasms activating the immune system, which then seems to prepare women for even the possibility of pregnancy.
Improves mental health
According to the sex therapist Vanessa Marin, skin-to-skin contact releases oxytocin, which is also known as the "cuddle hormone".
This can reduce anxiety and stress, while promoting feelings of closeness.
In 2013, UK-based neuropsychologist Dr David Weeks questioned more than 3,500 people about their sex lives over 10 years.
Results revealed those who have regular, healthy sex lives look up to seven years younger than people who do not get intimate two-to-three times a week.
Dr Weeks believes this is due to the release of endorphins that boost circulation and reduce stress, as well as the production of human growth hormones, which promote skin elasticity.
Makes you brainier
According to a study published in the Journals of Gerontology, sexually-active older adults perform better in verbal and visual tests.
This may be due to the release of oxytocin and 'the happy hormone' dopamine, which have both been linked to improved cognitive function.
