What are the effects of snow on human skin
When snow falls, the relative humidity in the air usually decreases and the atmosphere becomes drier. This causes a change in the epidermis as an effect of dehydration. We can notice it in our face, with deeper lines and flaking of the skin. We also notice itching in acral areas, such as the extremities (legs and arms) and particularly the hands and feet.Cold temperatures reduce the skin’s horny layer and the visible effects are similar to having dry skin. This is due to the fact that we lose cells more easily, which causes abrasions and inflammation from inclement weather. This is also usually a time when we drink fewer liquids, due to a reduced sensation of thirst and this causes a decrease in cellular hydration. This could also lead to illnesses such as dermatitis caused by scratching the skin when it itches and could cause skin damages like.
- “Frostnip” usually affects skin on the face, ears, or fingertips. Frostnip may cause numbness or blue-white skin color for a short time, but normal feeling and color return quickly when you get warm. No permanent tissue damage occurs.
- Frostbite is freezing of the skin and the tissues under the skin because of temperatures below freezing. Frostbitten skin looks pale or blue and feels cold, numb, and stiff or rubbery to the touch.
- Cold injuries, such as trench foot or chilblains, may cause pale and blistered skin like frostbite after the skin has warmed. These injuries occur from spending too much time in cold, but not freezing, temperatures. The skin does not actually freeze.
- Eye pain or vision changes caused by cold exposure most often occur in individuals who try to force their eyes open in high winds, cold weather, or during activities such as snowmobiling or cross-country skiing. Snow blindness is not directly caused by cold temperatures but does occur in snow conditions. Sunlight reflecting off the snow can cause a corneal injury or burn. Eyelids may become red and swollen. Eyes may feel dry and as though they have sand in them.
- An abnormally low body temperature (hypothermia) occurs when the body loses heat faster than it can make heat. (There may be other reasons a person has a low body temperature. For more information, see the topic Body Temperature.) Early symptoms of hypothermia include shivering in adults and older children; clumsy movements; apathy (lack of concern); poor judgment; and cold, pale, or blue-gray skin. Hypothermia is an emergency condition—it can quickly lead to unconsciousness and death if the heat loss is not stopped.
