Understanding the Different Types of Ultraviolet (UV) Radiation and Their Impacts On Health
Ultraviolet (UV) radiation is a form of natural energy from the sun that reaches the Earth’s atmosphere. UV radiation can have several different forms. Knowing the types of UV radiation and their impacts on human health is essential for anyone who enjoys the outdoors in sunny weather. UV, UVA, UVB, UVC radiation are the different types of UV radiation and have distinguishable properties in terms of their energy content, absorption abilities, and impacts on health.
Types of UV Radiation
Ultraviolet (UV) radiation is an invisible form of energy produced by the sun. It is divided into three distinct bands of the spectrum: UVA, UVB, and UVC.
UVA radiation has the longest wavelength and carries low energy levels. It has a greater ability to penetrate the atmosphere and reach the Earth’s surface. Although UVA has a lower energy level than other forms of UV radiation, it can still cause skin damage such as premature aging and wrinkles.
UVB radiation has a shorter wavelength and carries more energy than UVA. It is mostly absorbed in the atmosphere, but can still cause sunburns and has a higher risk of skin cancer.
UVC radiation has the shortest wavelength and carries the highest level of energy. This type of UV radiation is completely absorbed by the atmosphere and does not reach the Earth’s surface.
Impacts of UV Radiation on Health
Due to their ability to penetrate the atmosphere, UVA and UVB both have the potential to damage human health, albeit in different ways.
UVA radiation has been linked to premature skin aging, wrinkles, eye damage, and skin cancer. A sunscreen with a high UVA protection factor is recommended for protection when exposed to this type of radiation.
UVB radiation is the primary cause of sunburns and is also the main risk factor for most skin cancers. The intensity of UVB radiation depends on the season, time of day, and distance from the equator. It is recommended that people wear sunscreen with a high UVB protection factor when exposed to this type of radiation.
UVC radiation does not reach the Earth’s surface and does not have an effect on humans.
Take Action Today
Ultraviolet (UV) radiation has several distinctive forms and can have different impacts on human health. UV radiation can cause skin cancer, wrinkles, premature aging and other skin damage. It is recommended that people protect themselves from UV radiation by wearing sunscreen with a high UVA and UVB protection factor and avoiding prolonged exposure to the sun.
