Staying warm is important for your health, especially in winter. Being too cold can cause many health problems and exacerbate your symptoms when you get a cold or flu. Electricians will usually tell you the best way to keep warm is with the use of electric heating of some kind. Electricity is quick, clean, non-toxic and efficient. In addition it is widely available.
Years ago when not much heating was available, people used to get an itchy and painful condition called chilblains. It caused weeping sores on their extremities- toes, fingers, and sometimes ears – that took ages to heal. In fact, it would only heal when the warmer weather arrived. A condition called trench foot has also been noted by those who spend too much time in a cold environment.
