How do the sunburns appear?
No matter if we are sunbathing on the beach or swimming in the water, the doctors agree that we should constantly be wearing sunscreen and avoid the sun from 12pm to 17pm. If we are not wearing protection it is well known that when our holiday is finished we will return home with painful and uncomfortable reminders, (sunburns)
But, why and how do they appear on our skin?
It is the sun because of which we have the burns, but they appear because of our skin’s defense mechanism.
Namely, the radiation that comes from the UV rays damages the DNA of out cells.
There are 3 types of ultraviolet rays.
Has a smaller amount of energy but a longer wave length. Thanks to this we get our tan.
This radiation is with middle – length waves that can make sunburns appear.
This radiation is with the shortest length and the highest amount of energy and has the biggest influence on our skin. When our skin detects the UVA radiation, the receptors start to produce special cells – melanocytes. They produce additional melanin to darken the skin.
On the other hand, UVB radiation directly influences the DNA and damages it. If a higher amount of cells is damaged, an immune reaction starts and appears as a sunburn.
