The Japanese have a name for the syndrome of feeling cold a lot: It's hi-e-sho. Nobody really knows why it happens, although the Army has been trying to figure it out for years to help meet the needs of the troops, said exercise physiologist John Castellani of the Army Research Institute of Environmental Medicine in Natick.
In general, women seem to feel cold more than men, he said, and older people often feel colder than young ones in the same environment. Some people with less body fat also feel cold a lot but, then again, so do some obese people.
In some people, a slightly underactive thyroid gland may be the culprit, said Lisa Leon also a research physiologist at the Natick Army labs. So, if you're cold all the time, you should consider getting yourself checked.
