Overexposure to the sun can lead to sunburn and long-term sun damage, increasing the risk of skin cancer and premature aging. It's important to recognize the signs of sunburn, which include redness, pain, and sometimes blistering of the skin. Additionally, sun damage can manifest as wrinkles, dark spots, and leathery texture of the skin.

For example, a person who spends a day at the beach without adequate sun protection may experience sunburn, with their skin turning red and feeling tender to the touch. Over time, repeated sun exposure without protection can lead to visible signs of sun damage, such as fine lines, age spots, and a loss of skin elasticity.

According to the Skin Cancer Foundation, overexposure to the sun's ultraviolet (UV) rays is the most preventable risk factor for skin cancer. It's crucial to take precautions such as wearing sunscreen with a high SPF, seeking shade during peak sun hours, and wearing protective clothing and sunglasses to minimize the risk of sunburn and sun damage.
