If we watch it from a strictly chemical perspective, the sun gives us vitamin D which is important in maintaining the well being of our mental health, (among others like absorbing the calcium in the body) and low levels of vitamin D are often found in people with depression.

But, we are much more than physical bodies and the sun has an impact at a much greater level.

Pika thanks you for the compliment :)
