B rays negatively affect the upper layer of the epidermis. The skin begins to lose moisture strongly, melanin is intensely produced, redness appears. If you stay in the sun for a long time, the upper layer of the epidermis will begin to peel away, bubbles will appear, which will then burst. Body temperature can rise significantly as sunburn causes the same symptoms as a common burn, such as steam or hot water.
Negative consequences can be avoided by adhering to known rules. The time under the sun’s rays can be increased gradually. Sunning for the first time, you need to limit the time of stay under direct sunlight to 5 minutes. Every subsequent time increase the time by 1-2 minutes. After 1 week it is possible to sunbathe no more than 20 minutes.
Special remedies will help reduce the negative impact of UV radiation on the skin and allow you to increase the time of stay under direct sunlight. People with fair skin and blonde hair are not advised to sunbathe without protective cream with a factor of 20-30 units. And in the first week of your stay on the beach you need to use a protective spray or cream with a factor of 60 units.
Dark-skinned and dark-haired people can use a lighter remedy with a protective factor of 15 units in the first week of being on the beach and 5-10 units on the following days.
From 11 to 16 hours, the sun should be abandoned altogether. This is a time when ultraviolet radiation is particularly intense, so it’s better to wait it indoors or in shade.
