Sunscreen is a set of measures aimed at protecting the skin from damage caused by the sun's rays, especially ultraviolet (UV) rays. Excessive exposure to UV rays can cause sunburn, premature skin aging, wrinkles, sun spots and increase the risk of developing skin cancer.

Here are some sun protection measures you can take:

  1. Use sunscreen: Apply a broad-spectrum sunscreen with a sun protection factor (SPF) of at least 30. Be sure to apply liberally to all exposed areas of skin at least 15-30 minutes before going out in the sun, and reapply every two hours or after swimming or excessive sweating.

  2. Dress appropriately: Wear light but protective clothing, such as long-sleeved shirts, long pants, and a wide-brimmed hat to protect your face, neck, and ears.

  3. Sunglasses: Wear UV-protective sunglasses to protect your eyes and surrounding area from damage caused by the sun's rays.

  4. Avoid peak sun exposure: Reduce sun exposure when UV rays are most intense, usually between 10 am and 4 pm.

  5. Seek Shade: Seek shade, such as under an umbrella or tree, to reduce direct exposure to the sun.

  6. Avoid Tanning Lamps: Tanning lamps emit artificial UV rays that can damage your skin and increase your risk of skin cancer.

  7. Sunscreen for children: Children are particularly sensitive to UV rays, so it's important to protect them with child-safe sunscreens, wear protective clothing, and limit sun exposure.

Remember that sun protection is important all year round, not just during the summer or on a beach vacation. Even on cloudy days or during outdoor activities, UV rays can reach the skin and cause damage.
