What does uvb mean?
UVB stands for Ultraviolet B. It is a type of ultraviolet radiation that is emitted by the sun and can cause damage to the skin. UVB rays are the main cause of sunburns, and they can also lead to skin cancer.
UVB rays are shorter in wavelength than UVA rays, and they have more energy. This means that they can penetrate the skin more deeply, and they can cause more damage. UVB rays are strongest during the middle of the day, and they are more intense in the summer months.
There are a number of things that you can do to protect yourself from UVB rays, including:
* Wearing sunscreen. Sunscreen can help to block out UVB rays and prevent sunburns. Choose a sunscreen with a high SPF (sun protection factor) and reapply it every two hours.
* Wearing protective clothing. Wearing long sleeves and pants, a hat, and sunglasses can help to block out UVB rays.
* Seeking shade. Stay in the shade during the middle of the day, when UVB rays are strongest.
* Avoiding tanning beds. Tanning beds emit UVB rays, which can damage the skin and lead to skin cancer.
