The sun is an important star in our solar system. The sun warms the Earth and promotes animal and plant life on the planet. The sun also is vital for human health.
The National Institutes of Health says the human body was built to make good use of the sun. Sunlight helps regulate sleeping patterns, keeping one awake during the day and sleeping soundly at night. Sunlight also helps the body produce vitamin D, which is necessary for immune system support and normal bone function. The sun can boost mood. Lack of sun exposure, especially in winter months, can increase the risk for seasonal affective disorder, which is a form of depression. According to the World Health Organization, UV rays from the sun also can treat some health conditions, like skin ailments such as eczema and psoriasis. The sun also may help combat rickets or jaundice.
