Vitamin D production: Sunlight exposure triggers the production of vitamin D in the skin, which is essential for strong bones, muscles, and overall health.

Improves mood: Sunlight exposure triggers the release of serotonin, a hormone that regulates mood and boosts happiness.

Regulates sleep: Exposure to sunlight helps regulate the body"s internal clock, which regulates sleep-wake cycles.

Reduces risk of certain health conditions: Sunlight exposure can reduce the risk of certain health conditions such as multiple sclerosis, heart disease, and some types of cancer.

Sunlight and Skin Health

Apply sunscreen: Apply a broad-spectrum sunscreen with an SPF of at least 30 before going outdoors.

Seek shade: Seek shade during peak sunlight hours, which are typically from 10 a.m. to 4 p.m.

Wear protective clothing: Wear long-sleeved shirts, pants, and a wide-brimmed hat to protect your skin.

Avoid tanning beds: Tanning beds emit ultraviolet radiation and can increase the risk of skin cancer.
