The sun is essential for life on earth.
Here are some important things the sun does for you :
Vitamin D
One of the amazing things sunlight provides for us is Vitamin D. It is absorbed through the skin and converted to a state that the body can use. It usually only requires about thirty minutes of sunlight a day to acquire a minimum dose. Vitamin D is important for the creation and maintenance of bones. It is involved in the use of calcium in the body and performs many other important jobs.
Happiness
There have been studies that show that depression occurs in people during the change of seasons. As winter approaches and the earth tilts away from the sun, the days become shorter. This means less sunlight is available for our use. Many people find themselves depressed at this time of year, and the cause has been linked to the lack of sunlight. Indeed, people who sit under lamps that recreate the light spectrum of the sun have reported feeling happier and more energized. Sunlight also stimulates the pineal gland deep in the brain. This gland regulates our sleep/ wake cycles and triggers our bodies to activity or restful sleep.
Light
Without the light of the sun, there would not be any life on earth. There would be no star to orbit and no heat to sustain us. In short, without the life giving light of the sun, we would be a species lost. In fact, we would not even exist.
