Morning breath, a distinct lack of caffeine and day-after make-up face – when it comes to morning sex, we’re not going to deny there’s more than a few romance roadblocks in the way.

But if you and your partner are struggling to get on the same libido wavelength, a new study by the University of Siena has revealed exposure to bright lights can actually make your bloke more in the mood for sex – and better in bed. Win!

Researchers looked at men with clinically low sex drives, who on average rated their sexual satisfaction two out of 10.

They gave one group of men doses of bright light from a light box, for half an hour every morning. After two weeks, the men rated their sex drive 6.3 out of 10 on average.

The other group of men were exposed to dimmer light, and rated their satisfaction 2.7 out of 10.

Researchers theorise that light “inhibits the pineal gland in the center of the brain” which can lead to higher testosterone levels, and in turn higher libido and the ability for men to be ready for sex again once they’ve orgasmed.

Lead researcher Professor Faglioni also pointed out that light is connected to reproductive trends when it comes to the seasons. Note: he’s talking about the northern hemisphere, so the opposite to what happens down here.

“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,” he says.

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.
