At first, the notion of the "7-Day Sex Challenge" might sound like something out of a raunchy teen comedy more than an actual undertaking to improve your health and well-being, but if you follow the steps below, you could be in for some big beneficial changes (besides just the prospect of sex)!

The premise of the challenge is to have you and your partner (girl, guy, gay, straight...doesn't matter) have sex every day for seven days straight. Doesn't sound too difficult or unpleasant, does it?

And if you can't do it daily (Really? Not even for SCIENCE?), do it at least four times in a week. Studies have shown that people who have sex at least four times per week earn more money than those who don't!

Money aside, there's also the health benefits. Sex can be a great cardio workout, and you're using many muscles and muscle groups that you don't in your day-to-day life, or even at the gym.

Those benefits will leave you both looking and feeling younger. And it's not like it's an unpleasant way to get exercise!

Beyond the physical, regular sex can also have some pretty substantial mental benefits that are equally important. The endorphins released during the act have been scientifically proven to combat depression and anxiety, as well as reduce stress.

And, believe it or not, lots of chemicals that promote positive brain function are released during sex. For instance, endorphins, estrone, prolactin, oxytocin, and thyrotropin are all released by men upon climax.

Regular sex has been proven to lower blood pressure. Your systolic, more specifically. And lower blood pressure offers a host of benefits too long to list.

Did you know that orgasms can block pain? And not just make you forget about it for a while either. Studies have proven that stimulation can reduce chronic pain in the legs and back as well as reduce discomfort and pain from cramps, arthritis, and even headaches.

On a more emotional level, the challenge can kickstart emotional bonds that may have withered or plateaued. Few things are more intimate, so it creates a shared experience and trust between partners that isn't available elsewhere.
