Exposure to bright light can lead to greater sexual satisfaction in men who have low sexual desire, a new study suggests.
Scientists from the University of Siena in Italy found that using a light box, similar to those used to treat some forms of depression, increased testosterone levels. And this led to greater reported levels of sexual satisfaction.
The researchers carried out their study on 38 men who had been diagnosed with disorders which cause a lack of interest in sex.
One half of the group was treated with a light box, while the other half was treated with an adapted light box which gave out significantly less light. They were treated for half an hour early in the morning for two weeks.
When they retested the participants, they found that the group exposed to the bright light tripled their sexual satisfaction scores while the control group’s scores stayed roughly the same.
Light therapy is where a special lamp called a light box is used to simulate exposure to sunlight. A light box contains very bright fluorescent tubes – usually at least 10 times the intensity of household lights. They are commonly used to treat Seasonal Affective Disorder.
Some people seem to need a lot more light than others for their body to function normally.
In the northern hemisphere, the body’s testosterone production naturally declines from November through until April and then rises steadily through the spring and summer with a peak in October. You see the effect of this in reproductive rates, with the month of June showing the highest rate of conception. The use of the light box really mimics what nature does.
Men should avoid looking directly into the sun, no matter how good it feels, as this can cause blindness. Ha, ha!
