Does a sleeping body temperature lower?

Yes, a sleeping body's temperature lowers. Body temperature naturally fluctuates throughout the day, with a peak in the late afternoon and a low point in the early morning. This is due to the body's circadian rhythm, which is its internal clock. During sleep, the body's temperature drops by about 1-2 degrees Fahrenheit. This is because the body's metabolism slows down and blood flow to the skin decreases, which causes heat to be lost more slowly. The drop in body temperature helps to promote restful sleep.
