Basically the body temperature has to remain at a constant temperature. When our body's have a fever, it's to burn off/kill off whatever germ is attacking our immune system. When our body's are abnormally cool, our little white blood cells kinda don't move around the body as much to take care of disease or germs, allowing a cold to break through our natural heated body defenses. Reason why so many people come down with the flu, is usually people that may eat healthy, but attempt to save money by puting on more blankets, instead of turning up the heat.
I prefer 60-65f in my room. And I feel very comfortable with that during winter time.
THe only time i get cold, achy, and pain, is when i'm at work in a meat locker that can get as low as 40f. And after work I go home feeling like crap.
=^o.o^= When I'm cute I can be cute. And when I'm mean, I can be very very mean. I'm a cat. Expect me to be fickle.
