Sunlight can actually help your body make vitamin D.

When sunlight reaches your skin, specifically UVB radiation, it starts a process that eventually allows your body to produce vitamin D.

But your skin doesn't just absorb vitamin D from the sun like a sponge. 😂

Instead, the UVB light triggers a chemical reaction involving a substance already present in your skin. Your liver and kidneys then help convert it into forms your body can use.

And vitamin D isn't just about bones.

It helps your body absorb calcium and phosphorus, which are important for maintaining healthy bones and teeth. It also plays roles in normal muscle and immune function.

The funny thing is, your body basically has its own little vitamin-making system built into your skin.

You just have to step outside. 😭☀️

Of course, that doesn't mean you should spend hours in the sun. Too much UV exposure can damage your skin, so getting vitamin D isn't a reason to deliberately overexpose yourself.

Quick fact: Your skin can produce vitamin D when exposed to UVB light, after which your liver and kidneys help convert it into forms your body can use.
