Excessive exposure to sunlight can cause skin damage, including dry skin, dark spots, and wrinkles, and it increases the chances of skin cancer, which is the most common cancer worldwide, according to the American Cancer Society. To protect the skin at the beach, it is recommended to use sunscreen and ensure that it is "broad-spectrum" as indicated on the label and has a protection factor of 30 or higher. According to Temple Health, wearing a hat with a brim wider than 5 cm is also helpful for protecting facial skin. It is important to wear sunglasses to protect the eyes and the delicate skin around them, ensuring that they provide protection against UV rays. Between 10 AM and 4 PM, the sun's rays are at their strongest, so protective measures should be taken, and sun exposure should be minimized during this period. It is also advised to avoid prolonged sun exposure without sitting under an umbrella, to reapply sunscreen according to the product instructions—usually every two hours—and to drink water, which is one of the most important ways to keep the body hydrated in hot weather.
