Consciously enjoy summer and sun

Sun protection risk: UV index helps to assess risk

Finally, the temperature increases again. So let's get out into the garden or nature and enjoy some sun. This is also important for filling up the D storage after the sun free months. But be careful: for long stays in the sun, a tan threatens. The UV index can help to better understand this risk.

Spring sunshine is often underestimated

Temperatures up to 25 degrees Celsius: Summer has finally arrived. After the sunny months there is nothing better than charging the batteries in the garden, nature or in the cafe. But one should be careful. Especially in the spring, the sun's power is easily underestimated, it threatens sunburn. And this increases the risk of developing skin cancer. Health experts explain how to protect themselves.

Long periods of sun exposure increase the risk of sunburn and thus the risk of skin cancer. Even so, we can enjoy summer and sun, provided we know the dangers and protect us appropriately. (Photo: contrastwerkstatt / fotolia.com)

Sufficient supply of "sun vitamin"

In many countries, the vitamin D requirement cannot be met in winter.

Therefore, it is especially important during the hot months to be sufficiently provided with the so-called "sun vitamin". However, being too long in the sun can be dangerous, as it can lead to sunburn. And this increases the risk of skin cancer.

Increased Risk of Skin Cancer

Many thought there was a healthy tan.

But today people know that this is not the case. The fact that people in the 70s and 80s relentlessly hang out in the sunbath now depends on a sharp increase in skin cancer.

With a tanned skin, it may take longer for sunburn to occur, but the risk of skin cancer remains.

In addition, frequent sunbathing leads to premature aging of the skin with wrinkles and pigmented spots, and conjunctivitis and long-term cataracts may be the consequences for the eyes.

But summer and sun can be likened to knowing the dangers and protecting us appropriately. German Cancer Research Center (DKFZ) points to this in a message

UV index to evaluate the risk of sunburn

People do not have an early warning system for ultraviolet (UV) radiation. To know which sun protection measures are necessary when and if necessary, the UV index should be followed.

This has been developed by international expert panels to assess the current UV exposure to the sun. There are ten stations scattered across Germany that indicate the expected daily peak values ​​for sun-effective UV radiation at ground level.

The Federal Bureau of Radiation Protection (BfS) publishes measurement data and provides 3-day UV exposure forecast in

Interesting for vacation planning: The UV index has been defined by the World Health Organization (WHO) and is globally consistent. A UV index of 5 in Germany therefore means exactly the same as for example in Australia, Spain or Sweden.

It can be searched for other countries via the BfS website. Other institutions, such as the German weather management, publish the UV index on the Internet.

According to DKFZ, the rule of thumb is to assess UV exposure: The higher the UV index, the faster it can be for unprotected skin. The sunburn occurs and the more important are the appropriate protective measures.

"This is a practical guide for planning summer outdoor activities of all kinds", Dr. Susanne Weg-Remers, head of the cancer information service at DKFZ. "Those who follow the recommendations are best protected."

Recommended protection measures

The sun's power with its dangerous ultraviolet radiation is underestimated by many people. Experts complain in recent years, an increase in UV-induced skin cancer. Those who follow these tips can enjoy sun and heat without regret:

  • Look for the shade between, or better yet, spend lunch in the house between eleven and three, when the UV radiation is highest. [19659027] A simple and safe protection with clothes and headgear.
  • Portable sunglasses prevent eye damage. Make sure you have 100% UV protection or UV 400 and enough side protection.
  • To sunbathe, it is safer to avoid cosmetics, perfumes or deodorants when you sunbathe.
  • For adults, use a sunscreen with an SPF of at least 20 recommended. In addition, it should have UV-A and UV-B filters.
  • If you have sensitive skin, you should choose a high sun protection factor (50+) in midsummer and in southern countries.
  • Keep in mind adequate sun protection even in cloudy skies: up to 90 percent of dangerous rays penetrate into the cloud cover.
  • Side effects such as antihypertensive agents may have side effects associated with sunlight. Talk to your doctor if you are taking any medication.

Sunscreens can block vitamin D formation

Sunscreens can reduce the formation of vitamin D. However, according to the National Health Service UK (NHS), most people do enough vitamin D if their forearms, hands or legs are exposed to the sun during a short time every day. About ten to fifteen minutes are quite sufficient. This period is still low enough to avoid redness and sunburn when sunscreen is not used. (Ad) [19659036]
