Dear peewee17-ga;
Thank you for allowing me an opportunity to answer your interesting
question. Fundamentally, tanning one?s skin is takes place in most
people merely by ?controlling? the sunburn. Put more simply, sunburn
is an injury due to overexposure to the sun?s UV rays while tanning is
caused by limited exposure (often in a non-injurious fashion) to the
sun?s UV rays. Having said that, whenever one can be burned, one can
tan. With the exception perhaps of the thicker cloud cover caused by
lower temperatures, the temperature itself has very little to do with
the sunburn or tanning process:
?On an overcast day, especially an overcast rainy day, the amount of
UV reaching the surface is significantly reduced. Any overcast
conditions will reduce UV radiation reaching the surface. With this
said, partly cloudy conditions do NOT reduce the sunburn risk much.
Some people make the mistake of staying outside longer when there is
cloud cover. This increased time can make up for the fact there is
less UV radiation reaching the surface. This mistake is worst on a
partly cloudy day.?

?Your chances of developing a sunburn are greatest between 10 am and 4
pm, when the sun's rays are strongest. It's easier to burn on a hot
day, because heat increases the effects of UV rays, but you can get
burned on overcast days as well.?

Why don?t we burn or tan in the winter then, you might ask?
You will?if you are tough enough to stay out in the cold long enough
to get the UV?s necessary to do it. Have you ever seen a skier with
that white cream on his nose? That?s there to keep him from chaffing
in the wind but it also serves to protect one of the few places on his
body that is not covered by heavy winter clothing:
?Sun protection is also important in the winter. Snow reflects up to
80 percent of the sun's rays, causing sunburn and damage to uncovered
skin. Winter sports in the mountains increase the risk of sunburn
because there is less atmosphere at high altitudes to block the sun's
rays

In fact, one artic sled team discovered this the hard way. The UV
exposure there was so intense that even their dogs were injured by it.
?The team members not only had to protect themselves, it turned out
that the dogs would actually get sunburned on their noses ? the fur
was sort of "fried off" so they needed to put sunscreen on!!! Scary
stuff??

Needless to say, a human can be burned (or tan, if controlled) any
time. If a dog can get sunburn in the snowy, sub-zero arctic, YOU can
definitely be burned (or tan) on a cloudy, overcast day in the 70?s.
