Aloe Vera Sun Protection
Sunbeams are harmful to our skin, as we know from our early childhood, as we have always been encouraged to rub sunscreen so we can handle a nasty and painful sunburn. But a sunburn, which usually disappears without any residue, such as scars, is not the greatest risk you expose to direct and strong sunlight. NaturLex will tell you more about potential risks of sunbathing or just taking a long walk in the sun.
Why does the skin need protection from the sun?
Although sunburn is unpleasant and can sometimes hurt, the rays of the sun can cause long-term damage to the skin, which is definitely to be taken seriously. As you may already know, it is the UV rays that can damage our skin. In contrast to the light visible to us, UV rays are more energetic and shorter wavelength. The more energy-rich the radiation, the shorter the wavelength of this radiation. There are three different types of UV rays emitted by the sun. These are the UV-A, the UV-B and the most energetic and short-wave UV-C rays. However, on the surface of the earth, thanks to the ozone layer, which acts like a filter for the UV-C rays, normally only the UV-A and UV-B rays are emitted. How intensively these UV rays actually affect our skin depends on various factors. The day and the season, ie the distance of the earth to the sun, the geographical location and the cloud cover influence how much UV radiation actually reaches us. All in all, it can be said that UV radiation is much more intense in spring and summer. In places with a lot of water or snow, the radiation is reflected. Thus, the intensity is even significantly increased by stray radiation. Therefore, a sunscreen is not only intended for summer holidays, but should also be applied in the snow, for example when skiing to protect the skin appropriately.
How do UV-steels affect the skin?
Many people are already aware that UV rays can damage the skin, but how this damage, away from the sunburn, is currently unknown to most people. The different types of UV rays have different effects. But also the infrared rays contained in the solar radiation have an effect on our skin.
What UV-A rays cause
After only a short time in the sun, the UV-A rays stimulate the thickening of the upper horny layer and form the so-called light ulcers, whose tan, however, quickly disappears again. If you have a slightly more sensitive skin, you may experience light rashes or sun allergy. Excessive sunbathing without proper protection will visibly speed up wrinkling and skin aging. There is evidence in the form of pictures of truck drivers whose face half has aged normally and the half of the face exposed to the sun through the window has aged much more quickly. Take a look at such pictures on the internet, if they are not already known to you. According to scientists and researchers, UVA radiation in very high numbers may also cause damage to our genetic material. As some may already know, excessive exposure to UV-A radiation can increase the risk of skin cancer.
What UV-B rays cause
UV-B rays penetrate deeper into the skin than UV-A rays and so stimulate the formation of melatonin in the skin, creating a much-desired tan, which is longer lasting and does not disappear as quickly as the Skin stops producing excessive levels of melatonin. But it takes longer, until the desired tan arises. The UV-B rays build up a protective layer on our skin that can filter out further or repeated sunlight. Sunburn is mainly caused by the UV-B rays. This also depends on possible long-term consequences such as skin cancer.
What effect infrared rays
The infrared rays penetrate the deepest in the skin and are also harmful to the skin according to the Institute for Environmental Medicine in Dusseldorf. In the long term, this type of sun radiation leads to faster skin aging.
How important is it to avoid sunburn - and how?
It is very important to avoid sunburn, because this is actually a burning of the first or second degree skin and also because every sunburn increases the risk of getting skin cancer. For these reasons, it is essential and absolutely important that you and your loved ones cream in time on free body parts with sunscreen to protect your skin. These include above all the face, the neck, the arms and the ears. As additional protection against the harmful and dangerous IR and UV rays that can cause skin diseases, you should choose a suitable garment that covers as much of your skin as possible, and a headgear, such as a sunhat or cap , wear. But you do not need to be scared of the sun, as scientists have found that if skin is too little sun, it can lose its ability to build its own natural sunscreen. This is especially noticeable in early summer, shortly after the winter, when the skin could not yet get used to the sun. At this time you catch a sunburn with lighter skin quickly. The sun also stimulates the formation of the important vitamin D that is so important to our bones, along with calcium. It is about enjoying a healthy level of the sun, but not overdoing it for your own protection.
What is the self-protection time of the skin?
How long your skin can protect itself from dangerous sun exposure depends entirely on what type of skin you have. In general, the skin types can be classified into six broad categories.
The Celtic typeThe features of the Celtic type are characterized by a very light skin color, by slightly reddish or light blond hair and by freckles. These freckles occur in place of a tan. The self-protection time of people with this skin type is less than 10 minutes, so these people should ALWAYS apply sunscreen.
The Nordic Type
The features of a Nordic type are a fair complexion, freckles often appearing and blonde, light or dark brown hair. People with this type of skin are slow and have little brown and often have sunburn, as the self-protection time is here at 10 to a maximum of 20 minutes.
The mixed typeThe characteristics of a mixed type are a medium skin color, usually dark brown, light brown or dark blond hair, but sometimes also blond or even black hair. This skin type has little freckles, tans slowly to a light brown and sometimes has quite a sunburn. The self-protection time of the skin is here at 20 to 30 minutes.
The Mediterranean type
The characteristics of a Mediterranean type are a brownish-brown in the untanned state, which often has an olive undertone. Most of these people have brown or black hair and no freckles. This type of skin quickly turns to medium brown and rarely has sunburn since the self-protection time is over 30 minutes.
The dark skin type
The features of this type are an untanned dark to light brown skin, which often has a gray undertone. The dark skin type has black hair, no freckles and little sunburn. These people achieve a quick tan up to a dark brown. The self-protection time is over 90 minutes.
The Black Skin Type
The features of the black skin type are dark brown to black skin even in untanned condition, black hair and no freckles. These people almost never have sunburn because they also have a self-protection time of over 90 minutes.
But keep in mind that every skin is different, so everyone has to find out for themselves which protection factor they need. Excessively high levels of protection can cause the skin not to develop its own defenses and thus not get used to the sun. However, particularly bright types or risk groups do not pass on a LSF 50.Your NaturLex Team
