For the LAST Time, You DON’T Have Eyes On the Back of Your Knees.

Stop shining bright lights on your appendages.

Long shifts, long flights, sleepless nights, and new-born babies, are all reasons why you might need to sort out your sleeping pattern.

It’s no secret that our exposure to light regulates our circadian rhythm. Going outside in the morning and avoiding bright lights at night help regulate the sleep-wake cycle.

Shift workers may shine artificial light into their eyes to try to regulate their circadian rhythm.

But there is a strange, not-so-new method involving your knees, that you should seriously avoid.

The method is shining blue light onto the back of your knees.

There was research done at Cornell University that shows the blood vessels behind the knee are able to sense light in similar ways to our eyes.

Many scientists were skeptical, and rightfully so because this went against traditional research and wisdom.

Our eyes are specialized to view and respond to light and it doesn't make sense for other infrastructure in the body to do the same.

Think about it, we need oxygen, but we don’t have holes all over the body to deliver it — that’s the job of our lungs.

And since 1998, when the study was released, it has been disproven by a new and improved study.

So don’t start shining lights on your knees for hours a day.
