Allure reports that Forza, a supplement company, tried to answer an age old question. What's the best time of day for sex? After surveying 1,000 people they reportedly found that the most optimal time is 7:30 am. The reason? Reports claim that energy levels are the highest after rest, and at that time, activating endorphins that make us feel great throughout the day. But what if you're not a morning person? Researchers say that engaging in sex within 45 minutes of your wake up time can still be beneficial. Allure adds that morning sex can also lower blood pressure and stress levels.
