6 Surprising Ways Sun Affects our Bodies


The sun—without it, living things on earth wouldn’t exist. The light and heat from the big ball of fire in the sky sets the stage for our planet’s livable conditions. However, while the sun is essential to our bodies, too much or too little of it can have some interesting effects.
