Many people, especially sailors, are more likely to get sunburnt in spring than in summer. However, this is not due to particularly intense sunlight, as this is at its highest in summer. Rather, it is other factors that increase the risk of sunburn:
In fact, it is important to protect yourself from excessive sun exposure all year round, especially in summer when UV radiation is at its highest. Any exposure to ultraviolet radiation - UV for short - damages the skin. Sunburns in particular put a strain on the so-called UV lifetime accountExperts refer to this effect as "cumulative sun exposure". Every minute that the skin is exposed to sunlight is stored in this account, and the consequences can add up over the course of a lifetime to skin cancer.
As a rule of thumb, the denser the fabric of a garment is woven, the less UV radiation reaches the skin.
Sailors are particularly exposed to the sun, as it is not only out of the blue that danger threatens: the water surface also reflects large parts of the incident radiation; skiers are familiar with this phenomenon from snow. The result is usually severe sunburn, even on parts of the body that you thought were protected. This makes it all the more obvious, indeed necessary, to take precautions. The easiest way to protect yourself from sunburn is to Clothing with integrated UV protection. Their quality can be assessed quite well at the time of purchase. Nevertheless, the YACHT test of UV clothing at the Hohenstein Institute hardly measured any protective effect on some shirts. In some cases, the advertised good UV protection was simply not there, advertising and truth were miles apart. For buyers, this is particularly important due to the sometimes high prices annoying.
However, you should never on clothes alone leave. Ideally, you should protect yourself with clothing and sun cream for all the areas that the fabric does not cover, such as the face, neck and hands. The effect of both protectors is stated to be similar: for sun cream with the Sun protection factor SPF (Sun Protection Factor), for clothing with the UV protection factor UPF (UV Protection Factor). The UPF is quantified in a decadal system: 10, 20, 30 and so on. It indicates how much longer a person can stay in the sun without damage compared to unprotected exposure. How long you can be exposed to the sun without protection also depends on your skin type.
A person with particularly light-coloured, sensitive skin can only spend about ten minutes in the blazing sun without protection. Thanks to special clothing with UPF 50, this period can be extended to 500 minutes, i.e. more than eight hours. It is almost impossible to achieve the same level of protection with cream as with protective clothing, as the amount applied is never evenly distributed.
Did you know? Even when the sky is overcast, around 80 per cent of UV radiation still penetrates the clouds, making sunburn all the more surprising. Around 20 per cent of the original UV radiation is reflected by the surface of the water.
While hardly any skier would forget to put on sunglasses, the sailor's eye, especially on supposedly less sunny days, all too often wanders unprotected towards the horizon. The UV rays reflected by the water can also cause damage. The dangerous, permanent damage to the lens of the eye and the retina is initially painless and only becomes noticeable over years. The clouding of the lens, known to many people as "Cataract" (cataract) The onset of this condition at an advanced age leads to a gradual loss of visual acuity and an increasing sensitivity to glare, which can be explained by the diffuse refraction of light in the anterior segment of the eye. Exaggerated panic is not appropriate, but a Sunglasses with good UV protection is and remains a must for every cruise.
Especially Children's eyes are sensitive to sunlight. Because the lens of the eye is not yet fully developed, it is not yet able to filter UV radiation as well. In children under the age of ten, up to 75 per cent of UV radiation therefore reaches the retina, where it can cause irreversible damage. Responsible parents should therefore also ensure that their children wear high-quality sun protection for their eyes, which should also be made of shatterproof plastic to prevent injuries.
Many users of sunglasses confuse the particularly medically relevant UV protection with the noticeable glare protection. The latter is directly related to the tinting of the lenses, whereas UV protection is invisible to the user. Even with 100 per cent UV protection, the eyes may be dazzled if the tint is too weak. When used on reflective surfaces such as water (20 per cent reflection) or light-coloured sand (beach), sufficient tinting of the sunglasses is therefore another important selection criterion in addition to UV protection.
The colour of the lenses is primarily a matter of taste and does not correlate with the degree of UV protection. However, brown, grey and green lenses distort colours the least, so they should be the first choice.
To treat sunburn properly and alleviate the pain and discomfort, you should follow the steps below:
If the sunburn is extremely painful, forms large blisters or has symptoms such as fever, chills, nausea, dizziness or headaches, consult a doctor immediately. In such cases, more intensive medical treatment may be required.
