The sun emits a set of light rays made up of various elements. Filtered by the atmosphere, two-thirds of this radiation reaches the Earth. Of the rays that make their way to us, only UVA, UVB, visible and infrared rays influence the body.
These rays have beneficial effects: UVB rays promote the synthesis of vitamin D, essential for binding calcium to the bones, visible light has an anti-depressive effect and infrared rays have heating action that increases the skin temperature (an alarm signal to avoid sunburns).
However, in the event of excessive sun exposure, UVA and UVB rays can be particularly harmful. Over the short term, they can cause sunburns and trigger photosensitisation reactions (pathological skin symptoms related to the interaction of an exterior agent and the sun in the skin). Over longer periods, UVA and UVB rays are responsible for cutaneous ageing and most importantly the onset of skin cancers.
Tips and recommendations
- For protection, generously apply an appropriate sunscreen guaranteeing safety and tolerance with a high protection factor (SPF 50+) and anti-UVA protection.
- If your skin is very sensitive, choose products containing only mineral sun filters, which minimise risks of intolerance related to the use of chemical filters.
- Re-apply at least every two hours and after swimming or rubbing.
- Avoid exposure between 11 am and 3 pm.
- Don't forget essential protective clothing (tee-shirt, sunglasses, hat etc.).
- As much as possible, opt for sunscreens adapted to your skin type (ie. if your skin is oily, choose an oil-free non greasy fluid texture; etc.).
