How winter weather impacts your health



Cold weather brings along a range of problems for our body, from blood pressure to appetite, affecting also our mood. Here is the cost of winter.
The skin is the barrier between the body's internal organs and the environment. In cold weather it redirects the blood flow from the skin surface and the internal organs therefore preventing heat loss. One of the body's ways of staying warm is shivering, the involuntary trembling caused by rapid contraction and relaxation of muscles. But it is also a way to exercise without lifting a finger!
In winter the heart works harder, often leading to higher blood pressure. This is particularly dangerous for the elderly vulnerable as they face heart attacks and strokes. Because the skin redirects the blood flow internally, blood vessels constrict and the concentrated blood flow can cause blood clots, which are dangerous were the arteries are restricted.

The long winter months take their toll on our immune system, that's why we get colds and related infection more easily. Our whole body works hard in winter and it reacts to the cold as it reacts to stress and this affects our mood too. Winter short days and long nights quite often leave us feeling out of sorts; this is due to lack of melatonin, a hormone triggered by sunlight and it affects our daily body rhythms. Bright lights can help for the brain reacts by it by producing more melatoxin and our spirit will be lifted.
