Sunlight is the ultimate source of energy on earth. Without it, life on earth is not possible. Spending a few minutes every day out in the sunshine can provide you with a range of health benefits. It can also improve your mood and make you energetic. In fact, ancient Greeks used sunlight as a form of therapy called ‘heliosis’. Today, sunlight therapy is also practiced in the west and is known as ‘heliotherapy’.
Here are 8 amazing benefits of being in sunlight
It can Cure Seasonal Affective Disorder

Frequent exposure to sunlight helps to increase the Vitamin D levels in your body. Vitamin D helps your body to absorb essential minerals like calcium and phosphorous which are needed to form strong bones in the body. 
Low levels of vitamin D in the body during childhood can stunt the growth of a child. It can lead to several bone-related diseases like osteoporosis and osteomalacia. There is also an increased risk of fracture from an impact.
It Improves your Immune System
Studies have shown that regular exposure to medium intensity sunlight can give a boost to your immune system. A healthy immune system can protect you from various types of infections and pathogens.
It can Improve the Quality of your Sleep
A hormone known as melatonin is responsible for your sleep cycles. Exposure to sunlight prevents the production of melatonin during the day. This leads to more efficient production of melatonin during night-time which helps us to sleep better at night.

Excess time under sunlight can lead to skin cancer. However, research has found that optimal exposure to sunlight can prevent several conditions like colon cancer, prostate cancer, ovarian cancer, pancreatic cancer. This is all due to the effects of vitamin D.
