What are harmful effects of the sun?

Ahh A good one, Harmful effects of the sun, Forgive me on my lack of scientific Wording but i forgot the names of the cells

So there is the Outer skin cells,

When you go into the sun these get penetrated and the lower skin cells get heated aswell.

If you get sunburnt, this actually means the sun has litterally burnt your outer skin cells

if you get a really bad sunburn, then it can damage the lower cells too. if you get burnt really bad, your cell becomes... lets just say "infected" with skin cancer.

if your lower cells become cancerous then it can spread very very fast and if you do not get it removed it can spread to the rest of your body... ( lungs, heart, Liver) and you can die from harmful sunburn.

Positive though you get Vitamin D from going in the sun

Just dont stay in it for too long and dont get sunburnt, wear sunscreen and be safe.
