UVB rays

UVB rays are a type of ultraviolet light from the sun that reach the Earth's surface. They are crucial for our bodies because they help produce vitamin D, which supports bone health and immune function. However, UVB rays can also damage the skin and increase the risk of skin cancer and sunburns if we're exposed too long without protection. They mainly affect the outer layers of your skin and are strongest during midday hours and at higher altitudes. Wearing sunscreen, protective clothing, and seeking shade can help reduce harmful UVB exposure while still allowing you to enjoy sunlight safely.
