“Light Threat” Damages Your Thyroid?

Overall, cancer rates are on the decline.

That is, except thyroid cancer.

Rates of thyroid cancer have been steadily increasing for years.

And now, researchers have finally figured out why.

It all boils down to “light threat” that’s damaging your thyroid. Worse still, it’s raising your risk of developing thyroid cancer over 50 percent…

Researchers analyzed data on 464,000 adults from 50-71 years old who had taken part in the NIH-AARP Diet and Health Study.

They compared satellite imagery data, which estimated levels of nighttime light where people lived, against data from state cancer registries.

It turns out that people who lived in areas in the highest 20 percent of nighttime light had a 55 percent higher risk of developing thyroid cancer (compared to those in the lowest 20 percent of nighttime light).

In other words, too much artificial light at night could dramatically increase your risk of thyroid cancer.

This connection makes sense, since artificial light negatively affects your hormone levels — and thyroid cancer is a hormone-dependent cancer.

Exposure to light at night suppresses your body’s melatonin levels. This reduces your body’s ability to fight tumors.

It also disrupts your circadian rhythm, which is another risk factor for cancer.

Other similar studies have shown a connection between satellite-measured levels of artificial light and an increased risk of breast cancer, another hormone-dependent cancer.

Now, because this study was based on satellite images, it only measured outdoor light, and not indoor light.

However, with the prevalence of devices like smart phones, TVs, computers, tablets, etc. that emit massive amounts of blue light, I think it’s safe to say that indoor light further contributes to the problem.

I’ve been warning of the dangers of artificial light at night for years.

So, I’m glad the medical community is finally starting to “see the light.”

 

P.S. Light isn’t the only cause hiding behind thyroid cancer. There’s an everyday device that could be raising your risk of this type of debilitating cancer. Do you know what it is? Find out, here.
