I’m not exaggerating when I say that light therapy turned me into a new man.

I thrive on sunlight. That’s why, for years, I would almost fall into depression during the winter in Curitiba, the city where I live part of the year.

When the sun finally starts showing up again, I begin to feel more like myself. But those long, dark months were always difficult. Like millions of people around the world, I suffered from seasonal affective disorder.

Then I discovered full-spectrum light bulbs, and the brightness came back into my life—literally and figuratively. Even though they were incredibly expensive at the time, they were worth every penny. (The good news: they’re now affordable and easy to find—you can even buy them online.)

I’d still choose a sunny day over a gray one any time, but at least with this technique, I no longer feel like jumping out of my apartment window whenever the sky turns cloudy... again.

Jokes aside, light therapy as a treatment for this disorder is nothing new, but I was very excited when I came across a new study on the technique. It showed that light therapy may help with another widespread (and depressing) problem as well—sexual dissatisfaction.

The study found that in just 2 weeks, light therapy could improve sexual satisfaction in men with low libido and low sexual arousal.

The researchers gathered men who were seriously UNHAPPY with their sex lives. On average, they rated their sexual satisfaction at just 2 out of 10.

Half of the men received active light therapy using a light box every day for two weeks. The other half received a placebo light treatment in which the light was much dimmer.

After 2 weeks of treatment, the group exposed to the active light TRIPLED their sexual satisfaction scores. In contrast, the control group remained more or less the same.

Light Therapy Increases Natural Testosterone Production by 50%

The explanation? Testosterone is part of the answer.

In the active light therapy group, testosterone levels increased by more than 50%. The placebo group showed no significant increase.

We know that testosterone levels are closely linked to sexual satisfaction, but here’s something you may not know (I didn’t until I read this study): in the Northern Hemisphere, testosterone production plummets from November through April. It starts rising again in the spring and summer, reaching its peak in October.

Using a light box essentially mimics nature. It suppresses the pineal gland deep inside the brain, opening the door to greater testosterone production. In fact, it’s likely that this also triggers other hormonal effects we don’t fully understand yet.

It’s too early to say.

But this is a safe, natural treatment with other potential benefits as well—giving it a major advantage over medications, which can sometimes bring MORE problems (think side effects, drug interactions, and so on) than they’re worth.

And there’s certainly no harm in adding light therapy to other natural therapies that support libido, such as the ones you’ve already read about here at Natural Medical Post.

To your health,
