Let's be honest: a lot of us sit inside. . . all day.

Whether it's for work or to binge on the newest TV series, we simply aren't outside very often.

But, what would happen if you stopped going outside all together? 149,600,000 km away sunlight is being ejected from the sun, shooting across the solar system, through our atmosphere, and if the timing is right, landing directly on your skin.

Feels good, doesn't it?

And it's this sunlight that begins an amazing chain reaction, which helps to sustain your life: The Sunshine Vitamin, Vitamin D that is.

Interestingly, some of the cholesterol you consume is altered and stored in your skin.

And when that well-traveled Ultra Violet B sunlight hits your skin, it modifies this cholesterol.

The new molecule travels through the bloodstream to the liver, where it is altered again, and then to the kidney, where it is biologically "activated".

This activated Vitamin D works to absorb calcium from your food, ultimately leading to bone growth and strength.

In a way, your skin eats the sun and the sun grows your bones!
