Seems like having sex provides some key benefits to our health, but when we're not rolling around in the sheets with our partner, are we actually more susceptible to illness? Apparently we are. According to the Mayo Clinic, each time a man or woman is aroused the DHEA, or Dehydroepiandrosterone, hormone is released. This hormone gives your immune system a bit of a boost, helping your body to fight against bacteria, viruses, and other pretty nasty germs. No orgasm, no benefits however, so better put your guy or gal to work if you're lucky enough to be having regular sex.
While not having sex certainly doesn't mean you're going to come down with some major illness, you'll be missing out on some of these other great benefits as well. The DHEA hormone is also said to act as an antidepressant, make your skin look great, help repair any damaged skin tissue faster, and even increase apprehension and learning abilities.
A study of college students also found higher levels of immunoglobulin A, an antibody that is important for immune function, in those who had sex at least once or twice a week when compared to those who didn't. So, no sex means no antibody to fight off that flu!
