10 myths about sun protection

  1. Sun damage is not possible in windy, cloudy or cool weather.

FALSE: You can suffer sun damage in windy, cloudy or cool weather. Sun damage is caused by ultraviolet (UV) radiation, not temperature. In summer, a cool or cloudy day can have a similar UV level as a hot, sunny day. If it's windy and your face is red, it's probably a sunburn. There is no such thing as a "gale".

Sun damage is also possible on cloudy days, as UV radiation can penetrate some clouds, and can even be more intense due to reflection from clouds.

Consult the UV index to find out the level of UV radiation

 

  1. A fake tan darkens the skin, thus protecting the skin from the sun.

FALSE: A tanning lotion does not improve your body's ability to protect itself from the sun, so you will still need sun protection. Some fake tans have a sun protection factor (SPF), but you have to continue to protect yourself.

 

  1. Sun protection is not necessary when using cosmetics with a built-in SPF.

FALSE: Unless cosmetics are labeled with an SPF of 30 or higher, you should wear additional sunscreen under your makeup if you are going to be in the sun for an extended period. If you stay in the sun longer, use a separate sunscreen and reapply it every two hours, not just in the morning.

Be aware that most cosmetic products offer no protection or protection well below the recommended SPF 30.

 

  1. People with darker skin are not at risk of skin cancer.

FALSE: People with dark skin can also get skin cancer. Regardless of the skin type, exposure to UV rays from the sun and other man-made sources, such as sun beds, can cause permanent damage to the skin. People whose skin type is less likely to burn may still be at risk of developing skin cancer if they are exposed to too much UV. You still have to be careful of the sun.

 

  1. You can stay in the sun longer with SPF50 + than with SPF30 +.

FALSE: No sunscreen is armor and sunscreen should never be used to prolong time in the sun.

While it may sound a lot different, SPF 50 only offers slightly better protection against UVB rays, which cause sunburns and increase the risk of skin cancer. SPF 30 sunscreens filter approximately 96.7% of UV rays, SPF50 sunscreens filter 98% of UV rays. It is recommended to apply a sunscreen of SPF 30 or higher before going out, every two hours, after swimming, sweating or drying towels.

 

  1. Significant sun exposure is necessary to avoid vitamin D deficiency.

FALSE: Do not expose yourself to potentially harmful UV rays in order to get more vitamin D. Research suggests that prolonged exposure to the sun does not further increase vitamin D levels but increases the risk of cancer of the skin. When UV levels are 3 or more, most people get enough vitamin D from sun exposure for a few minutes. For example, you just have to walk to the car or to the shops.

If you live in areas with low winter UV levels (below 3), you can help maintain vitamin D levels by spending time outdoors in the middle of the day and exercising. 'physical activity. People who are at higher risk of vitamin D deficiency are those with naturally very dark skin, those who suffer from illnesses or take medications that affect vitamin D absorption, those who cover their skin. skin for religious or cultural reasons and those with little or no exposure to the sun. If you think you are at risk for vitamin D deficiency, talk to your doctor.

 

  1. You don't have to worry about skin cancer because if it is noticed, it is easy to treat.

FALSE: Treatment for skin cancer can be much more serious than just having a "burnt" lesion. It can include surgery, chemotherapy, and can lead to permanent scarring. Skin cancer can also spread to other parts of your body. Every year, many deaths are to be deplored due to skin cancer.

Pay attention to any new stains or changes to existing ones and see your GP immediately if you notice anything new or changing. And remember, prevention is always better than cure.

 

  1. Only sun worshipers can get skin cancer.

 FALSE: Excessive sun exposure doesn't just happen when you are deliberately looking to sunbathe. In a high UV environment like in France in the summer, we can be exposed to dangerous levels of UV radiation during any daily activity, such as working outdoors, gardening, walking the dog. or a picnic. This sun exposure builds up over time, which increases the risk of skin cancer.

 

  1. If you tan but don't burn, you don't need to worry about sun protection.

FALSE: There is no such thing as a safe tan. If the skin darkens, it is a sign of trauma to the skin cells, even if there is no redness.

The skin darkens in an attempt to protect itself, as UV rays damage living cells. If you tan easily, you are still at risk of skin cancer and you need to protect yourself from the sun.

 

  1. You cannot burn through a window, like in a car.

FALSE: You can burn yourself through a car window. The untinted glass commonly used in car side windows reduces, but does not completely block the transmission of UV rays.

This means that you can still burn yourself if you spend a long time in the car next to an untinted side window when the UV is high. Most often, people are burned in cars with the windows down, where they can be exposed to high levels of UV radiation ...
