You cannot get sunburn on a cloudy day |
|
Although clouds attenuate UV the diffuse sky radiation is sufficiently intense to get a sunburn unless the clouds are low and thick |
|
Too much sun is dangerous no matter your age |
|
The human skin and the immune system are sensitive to UV radiation through a whole life cycle |
|
Sunscreens protect me so I can sunbathe much longer |
|
Sunscreens protect you but their efficiency decrease after application - you should not stay longer in the sun than the SPF warrants |
|
You should avoid the sun between 11:00 and 16:00 |
|
Due to the highest sun elevation the UV radiation is the strongest during a day at this time |
|
If I don't feel the heat from staying in the sun l will not get sunburn |
|
UV radiation can not be sensed by the human because it is absorbed in the outermost skin layers |
|
UV radiation not only concerns the skin but also the eyes |
|
Sunburn is perhaps the most known effect, but UV radiation may also cause development of cataract |
|
Just re-aply your sunscreen to stay longer in the sun |
|
The sunscreens protects only for a certain length of time. After this any additional UV exposure is harmful |
|
People with fair skin and red hair are particularly sensitive to UV radiation |
|
The people with this skin and hair type combination is the most sensitive group of the population |
|
A tan protects you from an additional sunburn |
|
A tan is already a reaction on UV exposure and it only partially protects your skin |
|
The negative effects of sunburns are cumulative |
|
The ability of the human body to protect and repair UV-induced damages decrease during a lifetime |
|
The sun in winter and spring is not dangerous |
|
The UV intensity depends also on latitude, altitude and ground reflection like of snow |
|
Children should be especially protected |
|
Because of the high sensitivity of their skin and the cumulative effects of sunburns |
|
The darker your skin the more attractive you are |
|
This social attitude is changing - just a century ago you were more attractive when you were pale |
|
Reflection of UV radiation by sand and water must be considered |
|
The direct rays from the sun and the diffuse sky radiation are equally important for UV exposures after reflection at the ground |
|
It is necessary to stay in the sun because vitamin D is produced by UV radiation |
|
The time of exposition you need for vitamin D production is so short, that you always get enough without sunbathing |
|
The shorter your shadow is the more dangerous the sun burns |
|
When your shadow is short the sun elevation is high and UV radiation is more intense |
|
You cannot get a sunburn while you are in the water |
|
Water attenuates UV radiation but you may easily get a sunburn when swimming |
|
The higher the altitude the more the sun burns your skin |
|
The higher the altitude the smaller is the attenuation of UV radiation by the atmosphere |
|
It is not important to change your sun habits |
|
A change of personal habits is a first step in active protection against UV exposure |
|
The cheapest and the best sun protection is shade |
|
Shade protects you against the direct rays. However, you should still protect yourself against the diffuse sky radiation |
