Understanding the Importance of UV Protection

We’ve all heard the warnings and advice to make sure we protect ourselves from the sun’s harmful UV rays. But what, exactly, is a UV ray, and why is it so important for us to take preventative measures against it? Read on to find out the answers to these questions and more.

What is a UV Ray?

UV stands for ultraviolet radiation. These rays come from the sun and can also be generated from tanning beds. UVA, UVB, and UVC are the three types of UV rays. The Earth’s ozone layer helps to block UVC radiation, but both UVA and UVB rays can reach the Earth’s surface.

How Can UV Rays Harm You?

UV radiation can cause damage to the eyes, skin, and immune system. Overexposure to the sun’s UV rays can lead to sunburn, eye damage, and an increased risk of skin cancer. In addition, UVA and UVB radiation can damage the immune system, decreasing your ability to fight off infections.

Ways You Can Protect Yourself from UV Rays

Fortunately, there are several ways to protect yourself from the sun's rays:

• Avoid the sun during peak hours (10 am to 4 pm).
• Wear sunscreen with an SPF of at least 30. Reapply every two hours or after swimming or sweating.
• Wear protective clothing, such as long-sleeved shirts, hats, and sunglasses.
• Avoid tanning beds and sunlamps.

The Bottom Line

Ultraviolet radiation from the sun can cause several health problems if we don’t take steps to protect ourselves from it. Avoiding the sun during peak hours, wearing sunscreen and protective clothing, and avoiding tanning beds are all great ways to protect yourself from the sun’s harmful UV rays.
