Safe tanning: 8 simple rules
The summer has began and for a safe tan, especially with regard to children who must absolutely avoid sunburn, a few simple rules must be observed.
1. Protection factor </ strong>
Use sunscreens with a sun protection factor (SPF) equal to or more than 15. Just an average factor in most cases: in fact the cream to 50+ protection protects only 5 percent more than that of a factor 30. In the case children or people with light skin type is important not to drop below 15.
2. Periodically apply protection </ strong>
Apply the protection before leaving home, since the morning, and re-apply every two hours, especially after swimming, even though water resistant. The protection in fact disappears from the skin after this time period.
3. How long protect the skin </ strong>
Apply protective products also on tanned skin and if you have a dark skin type and may gradually reduce the protection factor. With a light skin type and for children, the high protection should be used always. Remember that sunscreens protect your skin from however UV damage and aging. The 80% of wrinkles are caused by the sun, which also dehydrates the skin and can increase the incidence of skin spots.
4. When sunbathing </ strong>
Avoid exposure when the radiation is at the height of its intensity in order to avoid damage to sum UVA and UVB. In fact, in the morning the sun has less UVB rays, those that burn the skin, but the same intensity of UVA rays, those aging skin and damage.
The sun’s rays are reflected off the sand and water, then stay in the shade or under an umbrella means taking about 50 percent of the spokes directly under the sun. On cloudy days, UV rays are able to filter and burn the skin should therefore not be exposed to long even in this weather. We must not forget also that the highlights do not take only the beach, but also in other sunny places.
5. Younger </ strong>
Very young children should not sunbathe, unless wearing hat, shirt and sunglasses, which can filter UVA and UVB. Always avoid the hours in which the radiation is at the height of its intensity.
6. Avoid “mirror” </ strong>
Dry thoroughly after bathing: the effect “mirror” of the droplets reduces the effectiveness of protective products, even those resistant to water. Pay attention to altitude, slightly overcast, reflective surfaces and wind: they reduce the feeling of danger, and so is the higher the risk sunburn.
7. Even sunscreens expire </ strong>
Beware of solar previous year: also the creams have a shelf life and after 12 months of opening no longer guarantee the protection factor initial.
8. Or antioxidants beta-carotene </ strong>
Do not think you avoid sunburn or taking antioxidants beta-carotene: there are no reliable proofs that you can avoid sunburn by taking products orally. The beta-carotene stimulates the formation of melanin, as well as give us a darker color, protects the skin from the negative effects of solar radiation and antioxidants can protect the skin against aging and the damaging effects of UV rays. But unfortunately they are not enough and the precautions to be respected equally.
