Why is Sunscreen Important? | UVA and UVB Rays

Sun exposure causes a lot of changes in our skin. However, you may feel relaxed for a while but, long sittings under the sun might be harmful to your skin. The change in your skin might not be visible at first but when it will start increasing with the passage of time, you will have to face the consequences. Premature aging and skin cancer are the two most common consequences of unprotected sun exposure which is why sunscreen is important. The sun emits two types of invisible radiations i.e. Ultraviolet A (UVA) Rays and Ultraviolet B (UVB) Rays which are very harmful to the skin

UVA and UVB Rays

UVB Rays which are said to be most effective between 10 am to 4 pm are the rays which cause sunburn. The harm caused by these rays is visible on the skin and can be treated before the situation gets worse. However, you can see and feel the skin, but the skin becomes abnormal due to the damage. They not only cause sunburn but are also responsible for premature aging and skin cancer.

UVA Rays, on the other hand, are comparatively more harmful as they penetrate deep into the skin without making you feel that they have entered your skin and destroyed everything that comes in their path. In fact, they don’t even leave the vital supportive substances which are important for the skin to look healthy and young. Unlike UVB rays, UVA rays are present throughout the day even when there is little daylight. They can cause skin cancer and premature aging.

Apart from skin cancer and premature aging, the other consequences of sun damage are wrinkled and thin skin, discoloured and uneven skin tone, dull and congested skin. Let us now have a look at why sunscreen is important.

Sunscreen Is Important

You must be thinking how to get rid of such a dangerous thing while your daily chores cannot be done without going under the sun. Do not worry, to protect yourself, all you have to do is liberally apply a sunscreen with minimum Sun Protection Factor (SPF) 30 which will give you protection up to 6 hours. Since both, UVA and UVB rays are present throughout the year, regardless of the weather or season, it is recommended to apply sunscreen on the exposed body parts every time you go out. While choosing the sunscreen, you must make sure that it has a label of ‘broad spectrum’ as it will protect you from both UVA and UVB rays. Remember, wearing a sunscreen is important.

The meaning of ‘PA’ ratings followed by plus signs is suspense to quite a lot of people. This label was developed in Japan and it depicts the level of UV protection offered by the sunscreen. Let us have a look at what every rating means:

PA+: Some Protection

PA++: Moderate Protection

PA+++: High Protection

PA++++: Extremely High Protection
