Sun in spring

The first warm rays of sunshine feel lovely. But the spring sun can damage your skin more quickly than many people realise. 

A quick look at the UV index in the Sola App will tell you when protection is needed.

Finally sitting outside again, face in the sun, that first coffee in the open air: emotionally, spring is a real highlight. For the skin, however, this time of year can be tricky. When should you apply sun cream? Many people base their decision on the air temperature, thereby underestimating the power of UV radiation. “When it comes to sun protection, it doesn’t matter how warm or cold it is – what matters is the UV index.”

UV Index: The most important figure in the Sola app

The UV Index describes the strength of the sun’s ultraviolet radiation. It is given on a scale of 1 to 11+, where 1 represents low exposure and 11+ represents extreme exposure.

The UV Index figure in the Sola app provides you with clear guidance:

•    It shows how intense the UV radiation is on that day.

•    It helps you decide whether and how you should protect yourself.

Experts recommend protecting your skin and eyes even at moderate levels of 3 or above. These levels can already be reached in March/April. So don’t underestimate the situation just because it’s not yet the height of summer.

UV radiation does not just cause sunburn on unprotected skin. Any damage caused by UV light also contributes to the long-term risk of skin cancer.

That’s why you should use the Sola app now to manage UV radiation safely.

Tips for nutrition and UV light in winter

With a vitamin D deficiency, which often occurs in the winter months, the body is permanently undersupplied with vitamin D.


Vitamin D is particularly important for healthy bones: If the body lacks vitamin D, the bones can lose stability.
The human body produces vitamin D when the skin comes into contact with sunlight.


To prevent a vitamin D deficiency, you should expose your face, hands and arms to the sun several times a week from spring to fall.
Use the Sola appto track your vitamin D intake. This will ensure that your body is optimally supplied with vitamin D.


A small amount of vitamin D is also taken in with food: It is found in oily fish, offal, eggs and mushrooms.Therefore, make sure you eat a balanced diet, especially in the winter months.

Sun protection in Winter

Sun protection in winter? 🌞

Winter brings short days and little sunlight. But in the mountains, when doing winter sports, and on long-distance trips, sunlight, or more precisely UV radiation, should not be underestimated. Here you can find out when and why you should protect your skin and eyes from too much UV radiation, even in winter.

UV protection in the mountains

In winter in the mountains, it is good to know that UV radiation increases by approximately 10 percent per 1,000 meters of altitude. Fresh snow reflects up to 90 percent of UV radiation, thereby intensifying it. Taken together, this means that on sunny days, UV exposure in the mountains can be so high even in the winter months that it can cause lasting damage to the skin and eyes.

Many people underestimate how strong UV exposure is at high altitudes and due to snow reflection. Sunbathing at a mountain hut and long outdoor activities can cause serious damage to your eyes and skin, even in winter. Experienced mountaineers and skiers know that protecting your skin and eyes is essential, even in winter. To prevent damage, you should protect exposed skin and lips with a broad-spectrum sunscreen (protection against UVA and UVB radiation) with a high to very high sun protection factor. For the eyes, sunglasses that cover the entire eye area with UV400 protection, UV400 ski goggles, or so-called glacier goggles with UV400 protection are essential.

Is a tanning bed the best option in winter?

Some people may think of tanning beds as a substitute for the lack of light and warmth during the cold season, especially since advertisements claim that they can also provide vitamin D. But this is not the right approach. This is because the UV radiation in tanning beds is usually as strong as the sun at the equator in summer at midday when the sun is at its highest.

The artificial UV radiation in solariums, like the natural UV radiation from the sun, is carcinogenic and can cause serious skin and eye diseases. These negative consequences always occur at the same time as the body’s own vitamin D production is stimulated. They far outweigh the benefits of UV-initiated vitamin D production. For this reason, the use of solariums is strongly discouraged internationally.

That’s why you should use the Sola app for optimal support.

The Sola app protects you from unwanted sunburn during all sporting activities in the mountains with its innovative timer.
