It might feel a hell of a lot more comfortable hooking up with someone in the dark—admit it, it's a good way to hide your back hair—but a new study suggests that, for those looking to have better sex, having the lights on is the way to go.
According to a study conducted by researchers at the University of Siena in Italy—who recruited 38 men diagnosed with low libidos—when those males spent a half hour each day in a room with a light box, their sexual performance improved.
Per The Telegraph:
Because sexual interest varies with the seasons, scientists have suspected that it might be influenced by ambient light levels. To test the theory, researchers from the University of Siena in Italy recruited 38 men diagnosed with low libidos and treated half of them with daily doses of bright light.
Early each morning for two weeks the men spent half an hour in a room with a light box, a panel designed to emit bright white light. At the end of the trial tests showed that their testosterone levels had risen significantly. They also reported higher levels of self-rated sexual satisfaction.
Similar effects were not seen in the other group of men whose light box was adapted to emit a low non-therapeutic level of light.
Here's what the lead researcher on the study, Professor Andrea Fagiolini, had to add:
"Before treatment, both groups averaged a sexual satisfaction score of around two out of 10, but after treatment the group exposed to the bright light was scoring sexual satisfaction scores of around 6.3 - a more than three-fold increase on the scale we used. In contrast, the control group only showed an average score of around 2.7 after treatment."
So what's this all mean for you? Well, as the days get shorter and the sun sets a little earlier over the next six months, it might be wise to get a little extra light in your room so that you don't leave your lady unsatisfied.
