The number 1 misadventure of the holidays is of course the sunburn. Unsightly, it is also dangerous for health since – it is proven – repeated sunburns increase the risk of developing skin cancer (melanoma, in particular).
To protect yourself against sunburn, there is no secret: you must avoid excessive exposure to UV rays (especially during the sunniest hours, that is to say between noon and 4 p.m. ) and slather on sunscreen regularly when enjoying the sun.
Does the parasol provide good protection against UV rays that cause sunburn? It depends, say industry experts.
Beware of indirect radiation, also responsible for sunburn
First, even when it is of very poor quality, the parasol has the advantage of filtering part of the UV rays: protection, therefore, although imperfect. For more effective protection, it is better to invest in a parasol made of thick acrylic fabric (at least 200 g/m2); some fabrics are even “anti-UV” treated.
However, against UV rays, the umbrella alone is not enough. Indeed: it is also necessary to take into account indirect radiation, that is to say UV which is reflected by the ground, by the sand, by the water of the swimming pool or the sea… Hence the need to wear sunscreen (with a protection index corresponding to your phototype) even when you spend the afternoon under a parasol!
