What are ultra violet rays?

We all love spending time outdoors, basking in the warm sunshine. But have you ever wondered about the invisible rays that come from the sun? These rays, known as ultraviolet (UV) rays, play a significant role in our daily lives and can have both positive and negative effects on our health.

In this blog post, we will explore what UV rays are, their different types, and the importance of protecting ourselves from their potential harm. Let's shed some light on UV rays!


What are UV Rays?

UV rays are a type of electromagnetic radiation emitted by the sun. They are invisible to the naked eye but can have various effects on our skin and eyes. UV rays are classified into three types based on their wavelengths: UVA, UVB, and UVC.


What Impact to UV/A Rays Cause?

UVA rays have the longest wavelength among the three types and can penetrate deep into the skin. They are present throughout the year, even on cloudy days, and can pass through windows and clothing. UVA rays are associated with premature skin aging, wrinkles, and some forms of skin cancer.


What Impact do UV/B Rays Cause?

UVB rays have a medium wavelength and are responsible for sunburns. They are strongest during midday and in the summer months. UVB rays do not penetrate the skin as deeply as UVA rays but are a major cause of skin reddening, sunburn, and can contribute to skin cancer development.


What Impact do UV/C Rays Cause?

UVC rays have the shortest wavelength and are almost entirely absorbed by the Earth's atmosphere. They are not a concern for human exposure as they are typically filtered out by the ozone layer.


It's Essential to Protect Against High Ultra Violet Exposure

Excessive exposure to UV rays can have harmful effects on our skin and eyes. Here are some essential tips to protect yourself from the potential damage caused by UV rays:

1. Wear Sunscreen: Apply broad-spectrum sunscreen with a Sun Protection Factor (SPF) of 30 or higher. Choose a sunscreen that protects against both UVA and UVB rays and remember to reapply every two hours, especially when outdoors.

2. Seek Shade: When the sun is at its strongest, typically between 10 am and 4 pm, seek shade under trees, umbrellas, or wear protective clothing to reduce direct exposure to UV rays.

3. Wear Protective Clothing: Cover exposed skin with lightweight and tightly woven clothing. Wide-brimmed hats and sunglasses with UV protection can shield your face and eyes from direct sunlight.

4. Avoid Tanning Beds: Tanning beds emit UVA and UVB rays, which can significantly increase the risk of skin damage and skin cancer. It's best to avoid them altogether.

5. Check the UV Index: Be aware of the UV Index, a measure of the UV radiation level at a specific location and time. Plan outdoor activities accordingly, aiming to minimize exposure during peak UV hours.


Understanding the power of UV rays and taking appropriate precautions is crucial for maintaining healthy skin and eyes. By staying informed about the different types of UV rays and adopting sun-safe habits, such as wearing sunscreen, seeking shade, and wearing protective clothing, we can enjoy the outdoors while minimizing the potential risks associated with UV exposure. So, let's embrace the sun responsibly and keep our skin and eyes protected from the invisible but mighty UV rays!
