Chimpanzees have cleaner beds than humans, study says

Chimpanzees maintain cleaner sleeping environments than humans by building new nests each night, resulting in lower bacteria levels. A study by North Carolina State University found that only 3.5% of bacteria in chimpanzee nests originated from their own bodies, compared to 35% in human beds. This difference is attributed to the chimpanzees' habit of changing their sleeping area daily, unlike humans who typically sleep in the same bed repeatedly.
