Reseach- Standing in Sun Boost testosterone levels and Drive For Men

         The study was inspired by previous research showing male sexual desire fluctuates with the seasons, decreasing in darker winter months. It focused on men over 40 because one in four in this age group reports problems with sexual desire.

The Italian researchers considered 38 men with one of two conditions characterised by a lack of interest in sex – hypoactive sexual desire disorder or sexual arousal disorder.

        The testosterone levels and interest in s*x were established before they were divided into two groups. One received regular treatment with a box that emitted 10,000 lux of light – the equivalent of bright daylight – from a distance of one metre.
The other group was exposed 100 lux, the amount of light on a very dark overcast day. Both groups used the light box for around 30 minutes every day between 7am and 8am, for two weeks.
         The men were then retested and the researchers found those exposed to bright light reported sexual satisfaction levels three times higher than before the treatment, while there was no significant change in the other group.
        Professor Andrea Fagiolini, who conducted the study with colleagues at the University of Siena, said: 'Before treatment, both groups averaged a sexual satisfaction score of around two out of ten, but after treatment the group exposed to the bright light was scoring around 6.3 – a more than three-fold increase.
