Prolonged sun exposure generally does not trouble most people. However, it is vital to ensure protection for babies, children, and individuals with sensitive skin. It's crucial to reduce time in the direct Sun around mid-day due to the intense solar radiation. Sun-protective clothing, a long-sleeved shirt and pants, a wide-brimmed hat, and UVA and UVB-blocking sunglasses are particularly helpful in blocking UV radiation's harmful effects. Consider this! The reflection from snow can almost double the intensity of the Sun's UV radiation.
