Dale C. S. Destin: The sun, our ultimate source of energy, provides warmth and light essential for life. However, it also emits ultraviolet (UV) radiation, which, while beneficial in small amounts, poses serious health risks with excessive exposure.

In Antigua and Barbuda, we are now entering the Extreme UV Radiation Season—March to September—the period when the UV Index (UVI) frequently reaches 11+ or extreme levels. During this time, the risk of sun-related ailments, including skin cancers (deaths), is at its highest.

Understanding UV Radiation

UV radiation comes from the sun and is categorized into three types: UVA, UVB, and UVC. Fortunately, UVC is completely absorbed by the ozone layer and does not reach the Earth’s surface.

UVA and UVB penetrate the atmosphere and can cause harm. Although about 90% of UVB is also absorbed by the ozone layer, it is still strong enough to cause significant damage to human skin and eyes.
