Quick question here: Lately, I am in the position where I have to be out in the cold at night. I dress warmly, but after 2-3 hours I do start getting a little cold and come back into a warm area. Temperatures outdoors generally range from 25-35 degrees F. After I then go to bed and awaken in the morning, I find my urine bright yellow and I sometimes have a headache. I get the same symptoms from exercising, which of course is dehydration and I drink water to compensate, but is there something about being out in the cold causing dehydration also? Thanks, Sherwood

My understanding is that ppl in the cold aren't as aware of the need to rehydrate (i.e. drink) as in the heat. One loses water through respiration in dry air in the cold just the same as in hot air. Dehydration is a risk in winter, see: "http://www.ext.colostate.edu/pubs/columnnn/nn990203.html Water "http://www.allweathersports.com/winter/winter.html#M- iscellaneous Miscellaneous "http://www.inquiry.net/outdoor/winter/health/hypothermia_b- p.htm Hypothermia "http://www.bostoncoop.net/balm/hypothermia.html Street Medic's Guide to Hypothermia Be well.
