What are UVA and UVB rays, and how do they affect you if you don't protect your skin?
We all know that long exposure to the sun's rays without adequate protection is not good. Every year around this time, the media bombards us with reminders about the importance of protecting ourselves from the sun, but you may not know what exactly we need to protect ourselves from.
Well, those responsible for why we have to use sunscreens up and down are UVA rays and UVB rays, which you may already know. But it's not just the sun that poses a danger to us, other light sources can also have an impact on our skin, such as the blue light from digital screens.
Here we explain the difference between some radiations and others and how they affect your health if you do not protect yourself from them.
UVA and UVB rays, what are they and how do they affect you?
The sun sheds several types of radiation on us: visible, like light, and invisible, like ultraviolet radiation. This last type of radiation is made up of three types of radiation: the ozone layer protects us from UVC rays, but we have to take care of UVA and UVB radiation.
The UVA radiation They are long-wave radiation and are responsible, among other things, for our tan. This radiation penetrates very deeply into our skin and is what is used in tanning beds.
And excesses are not good. Long exposure without adequate protection causes, in the long term, the skin to age prematurely and, in extreme cases, causes skin cancer, since the depth to which these rays penetrate the dermis can cause changes in DNA. . In addition, it is also harmful to the immune system and our eyes, since it can cause ocular cataracts.
The UVB rays, on the other hand, are medium wave rays and affect us at a more superficial level than the previous waves. They are the cause of superficial tanning and are also used in medicine to treat skin conditions.
However, high exposure to these rays, in addition to darkening the skin, can also cause burns, a thickening of the outer layer of the skin, premature aging, melanoma and other skin cancers.
So now you know, although sunbathing has a long list of benefits, we must also be aware of its risks and be prepared. Now you can continue protecting yourself from the sun, but knowing what you are protecting yourself from!
We not only have to protect ourselves from the sun
That's how it is! And the blue light from the digital screens of our devices and infrared rays also affect our skin. But what are they?
Blue light is the light emitted by the screens of our digital devices, although it is also found in sunlight. These are radiations that are normally associated with vision problems when we are exposed to them for a long time, but the truth is that they also affect our skin. As? Although they do not cause burns like UVA and UVB rays, they do cause premature aging of the skin, produce diffuse pigmentation and cause spots to appear.
Infrared rays, on the other hand, constitute 40% of the radiation we receive, but despite that, we do not take them into account when it comes to protecting ourselves. These rays penetrate up to 10 millimeters into our dermis and cause loss of elasticity and firmness and accelerate the aging of our skin.
Therefore, it is important to protect ourselves from these rays because, although less, they also have an impact on our health, we just do not take them into account as much because they are not as well known or cause damage as immediate as UVA and UVB rays.
To protect ourselves from these radiations, all you have to do is use our sunscreens. Have you already chosen yours?
