So Summer is almost upon us, hooray!!
I thought it would be really beneficial to inform you of the different types of Ultra Violet Sun Rays.
Did you know there are 3 types of Ultra Violet Rays?
Do you know what each means for your body, health and skin?
If not, no need to worry here are some key facts
Sunshine is made up of different rays. Ultraviolet (UV) Radiation is the part of the sunlight which causes sunburn, skin damage and skin cancer. Ultraviolet radiation can be broken down into three bands; UVA, UVB AND UVC.
The amount of UV Rays reaching the earths surface varies throughout the day. The danger period in between 10am and 3pm. These are the hours where skin damage occurs the fastest.
On a cloud free day, we can feel maximum ultraviolet rays. However ultraviolet levels are not related to the air temperature. There can be high levels of ultraviolet rays on cooler days, and UV Rays still reach the earths surface where there is cloud cover.
The higher the UV Radiation levels, the less time it takes for skin damage to occur. This is why UV Radiation levels are more intense between the hours between 10am and 3pm.
UVA RAYS - Remember as YOU ARE AGEING (UVA)
LONG TERM SKIN DAMAGE AND PHOTO AGEING -
In other words, premature ageing, wrinkles and sun spots.
UVB RAYS - Remember as YOU ARE BURNING (UVB)
CAUSE OF SUNBURN
Unlike UVA, they have different strengths all year round.
UVB - MOST COMMON CAUSE OF SKIN CANCERS!!!!!!!!!!!!
UVC RAYS -Remember as DANGER RAYS
THE MOST DAMAGING OF THEM ALL!!
UVC Rays are the most deadly of solar rays, however the ozone layer stops these from reaching the earth. Don't be fooled by this, this type of UV Rays still has an effect.
While I'm here, I wanted to touch on SPF
What is a SPF?
An SPF is a SUN PROTECTION FACTOR
SPF's protect from UVB Rays, the kind of radiation that causes SUNBURN, SKIN DAMAGE & CONTRIBUTES TO SKIN CANCERS.
For best protection, it is recommended using the following;
SPF 15 - 93% PROTECTION
Allows 7 out of 100 photons through
SPF 30 - 97% PROTECTION
Allows 3 out of 100 photons through
Photons are particles from a radiating light source, the sun!!
