Sunlight lowers cholesterol.
The sun converts high cholesterol in the blood into steroid hormones and the sex hormones we need for reproduction. In the absence of sunlight, the opposite happens; substances convert to cholesterol.
The sun’s rays lower blood pressure.
Even a single exposure significantly lowers blood pressure in individuals with high blood pressure. On the other hand, pharmaceutical drugs such as Statins have side effects, such as robbing the body of Coenzyme Q10. CoQ10 is essential for cellular and heart energy.
Sunlight increases oxygen content in human blood.
And, it also enhances the body’s capacity to deliver oxygen to the tissues; very similar to the effects of exercise. The sun has a great effect on stamina, fitness and muscular development.
Sunlight builds the immune system.
The white blood cells, which increase with sun exposure, are called lymphocytes, and these play a major role in defending the body against infections.
Sunlight can cure depression.
The noon sunshine can deliver 100,000 lux. When we sit in offices for the best part of the day, out of the sun, under neon and artificial lights (150–600 lux), we are depriving ourselves of the illumination of nature. Sunlight deprivation can cause a condition called seasonal affective disorder (SAD), a form of depression. It is more common in winter months, but also common in people who work long hours in office buildings.
