In summer, the pleasure of good weather can sometimes be ruined by a painful experience: the sunburn. A doubly paid penalty, because in addition to being unsightly, the sunburn is especially very dangerous for the skin.
Indeed, a severe sunburn can cause burns to the second degree! Not to mention the longer term risks of skin cancer.
Who has not already experienced this experience: we spend a good time on the terrace or at the beach without worrying about the passing of time, and when we realize, it is too late, we caught a sunburn! But in fact, what exactly is a sunburn?
Sunburn: from inflammation to burning
A sunburn is an inflammation of the skin due to too intense exposure to the sun's UV rays. Only a few hours after exposure to the sun, sunburn is manifested by symptoms such as redness, itching and often pain. In medical terms, we speak of solar erythema (erythema meaning redness).
Generally, we associate the sunburn with the summer season - which is not wrong, of course. But it is important to remember that a sunburn can also occur at other times of the year, for example in winter when skiing.
Also be aware of reverberation effects related to snow, water or sand ... that can accentuate the effects of ultraviolet on the skin.

The different stages of the sunburn
A sunburn can be more or less severe. And depending on the importance of the sunburn, the symptoms are not the same. At an early stage, the skin becomes colored, becomes pink. In the ideal case, the skin adapts to the dose of UV radiation to which it has been exposed: the stratum corneum thickens and melanin increases the pigmentation of the skin: the skin will tan!
Then the skin is colored - a little too much, it turns red, and this is felt: the skin is sensitive to touch, the slightest friction with clothing is painful. If the burn is greater, the skin becomes purplish red and begins to swell. The pain is more intense. Little by little thereafter, the skin will peel.
In case of more intense sunburn, blisters appear on the skin always red. This corresponds to a second degree burn.
At an even more important stage, sunburn can even lead to fever and chills. In fact, there are symptoms related to heat stroke.
When the sunburn has reached this stage (from the second degree of burn), it is advisable to consult a doctor.
