According to the study conducted in Italy, the testosterone levels in men can be increased by exposure to the bright lights which leads to greater sexual satisfaction.

Researchers at the University of Siena in Italy, in the study, found that regular early-morning use of a light box-similar to those used to combat Seasonal Affective Disorder or SAD-helped men in increasing their testosterone levels an in improving their sex lives.

The treatment may prove during the Northern hemisphere’s darker winter months, said Andrea Fagiolini, a lead-professor in the study and who presented it at the European College of Neuropsychopharmacology conference in Vienna on Monday.

He said, “The increased levels of testosterone explain the greater reported sexual satisfaction. In the Northern hemisphere, the body’s testosterone production naturally declines from November through April, and then rises steadily through the spring and summer with a peak in October.”

Reports said that 350 percent men above age of 40 years reports problems of low sexual desire.

While conducting the study, Fagiolini’s team recruited 38 men diagnosed with either hypoactive sexual desire or sexual arousal disorder, which comes from the lack of interest in sex.

The team, after the initial reading, divided men into two groups and provided regular treatment with a bright light box to a group, while the other group was treated with a light box to give out significantly less light.

Fagiolini said, “We found fairly significant differences.”

“Before treatment, both groups averaged a sexual satisfaction score of around 2 out of 10. But after the treatment, the group exposed to the bright light was scoring sexual satisfaction scores around 6.3. In contrast, the control group only showed an average score of around 2.7 after treatment.”
