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 pa erns, keeping one awake during the day and sleeping soundly at night.

The sun also may help combat rickets or jaundice. While there are many benefits of ge ing ample sunlight, there also are some downsides to the sun and UV exposure, particularly in regard to the skin. Yale Medicine says that too much sun exposure can lead to photoaging of the skin. Symptoms include wrinkling, loss of skin elasticity, hyperpigmentation, sun spots, and redness.

These people burn easily and may not tan readily. Overexposure to the sun also increases the risk for skin cancer, the most common cancer in the United States and elsewhere around the world. UV rays can cause changes to cells that make them rapidly grow and divide, leading to extra cells known as tumors.

Basal cell and squamous cell carcinomas aect more than two million people each year in the U.S. Melanoma is less common but more serious, aecting roughly 68,000 Americans each year. The Dallas Dermatology Center says about 10 to 30 minutes of safe sun exposure each day can help a person get the benefits of vitamin D and other perks of the sun without the harmful side eects. Individuals concerned about sun exposure should speak with their dermatologists to determine healthy ways to get some sun.
