Where low core body temperature when sleeping, while parties such as the fingers start, heated as a result of the dispersion and distribution of heat.
Have been observed this phenomenon in many studies, but the new research is the first to determine the increase in temperature the fingers on the long period of time up to 45 hours, and shows that this increase does not occur only at night, but at any time when human sleepy.
