Men perform better in bed when put under the spotlight, study finds
a new study suggests that bright light may help men with flagging sex drives to shine in bed.
So longer exposure to light increases testosterone...To test the theory a team of Italian researchers from the University of Siena recruited 38 men diagnosed with low libidos and treated half of them with daily doses of bright 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.
