Why does our skin change color in the sun?
When we spend time in the sun, our skin gets darker on purpose.
It darkens to help protect the skin from getting sunburned and hurt by the sun.
So, a tan is the skin’s way of helping itself stay safe in sunlight.
Key idea
- Sunlight can hurt our skin if we stay out too long.
- Darkening is a natural response to help protect the skin.
- Always wear sunscreen and take breaks in the shade.
