The very REAL reason you and your guy need a beach vacation.

Fall starts this week, so you know what that means. Pumpkin spice is everywhere, Target is already selling Christmas decorations, the days are getting shorter, and, according to science, men are getting significantly less horny.

What? Was that last one a surprise?

Unfortunately, there is scientific data that suggests that the sex drive of men drastically decreases during the darkest months of the year.

Recently, Professor Andrea Fagiolini of the University of Siena in Italy argued that, “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.”

And testosterone plays a huge role in men’s overall sexual arousal and sexual satisfaction. So, sure, dudes are going to reach a horniness peak just in time for Halloween — hence all the "sexy" costumes, I suppose — but from Thanksgiving to April Fool’s Day, we’re looking at a season of sexual “meh” for men in the Northern Hemisphere.


How can we combat that? Flannel lingerie for winter? Sneaking Viagra into your Christmas eggnog?

Professor Fagiolini and a team of scientists at the University of Siena have been studying this phenomenon and have found a potential solution — light therapy.

That’s right. Regular exposure to bright light can increase men’s testosterone and lead to significantly higher sexual satisfaction rates, according to this most recent study.

If light therapy sounds familiar, you’ve probably heard it used to combat seasonal affective disorder (SAD). But bright light isn’t just effective for dealing with mood disorders, apparently.

In the details of this new study, presented at Vienna’s European College of Neuropsychopharmacology, Professor Fagiolini’s team recruited 38 men who were all suffering from hypoactive sexual desire disorder or sexual arousal disorder — i.e. they really weren’t interested in sex.

They split the group into two, and one of the groups began to receive regular treatment with a light box. Every day, right in the morning, the group was exposed to bright light for 30 minutes. After just two weeks of treatment, the group receiving the light treatment noted a significant increase in their testosterone levels — spiking from 2.1 ng/ml to 3.6 ng/ml.


Additionally, after the light therapy, the group also reported that they were enjoying sex a LOT more.

The group’s average sexual satisfaction score before the treatment was a 2 out of 10 (sad trombone sound). But, following the treatment, the light therapy group’s average sex satisfaction score leaped to 6.3, more than TRIPLING their previous score.

When asked WHY light was playing such a huge role in increasing sexual satisfaction, Professor Fagiolini noted that, "We believe that there may be several explanations to explain the underlying mechanism. For instance, light therapy inhibits the pineal gland in the centre of the brain and this may allow the production of more testosterone, and there are probably other hormonal effects."

However, the research team was quick to point out, “We're not yet at the stage where we can recommend this as a clinical treatment. However, if this treatment can be shown to work in a larger study, then light therapy may offer a way forward.”

So, extra light isn’t 100% proven to be an aphrodisiac, but there is evidence that shows that a little sunlight might make a big difference in your sex life, if your man sometimes struggles to get in the mood.


Because what will it hurt to get a little extra sunlight in the morning? Take a walk, sit on a bench, get some fresh air, sit in the sun, and soak up some Vitamin D.

Not only is it good for your complexion and seasonal mood disorder, but it might make your sex way hotter too.
