Okay, lets all admit it, summer this year has been pretty crappy. In fact, it feels like winter still! So how do you make the most of the sun on those occasional toasty days? How are you going to work on that desperately needed tan? The answer is this: TAKE OFF THOSE SUNGLASSES!
You must think I’m crazy right? How can taking off your sunglasses give you a better tan?
Well believe it or not, it’s true! This is how it works:
First thing you need to know is that the pituitary gland gets information from your optic nerve. So when the optic nerve senses the UV from the sun (which wearing glasses prevents) it tells the pituitary gland to kick start the melanocytes into overdrive. Melanocytes are the cells that help produce “color” in not just your skin, but also your hair, eyes etc. People who have fairer skin have the same number of melanocytes as people with darker skin, but it produces less melanin (there are also two types of melanin which I won’t get into). The increased melanocyte activity = better tan.
Okay so summary:
Sunlight hits eye’s optic nerve = signals pituitary gland to kick start melanocytes to work harder = increase tan.
****Be warned though! I’m not saying that LONG time exposure to UV rays is good for your eyes or skin for that matter, just possibly assist with the tan 😉
