Sun exposure refers to the amount of time your skin is in direct contact with the sun. While some sunlight is beneficial, as it helps your body produce vitamin D, too much can lead to skin damage. This damage can cause sunburn, premature aging, and increase the risk of skin cancer. To protect yourself, it's important to use sunscreen with a high SPF, wear protective clothing, and seek shade during peak sunlight hours. Remember that even on cloudy days, harmful UV rays can still reach your skin, so taking precautions is essential for maintaining healthy skin.
