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.

Why do chimpanzees have cleaner sleeping environments compared to humans?

• They have fewer bacteria on their skin.

• They change their nests every night.

• They sleep in trees.

• They use disinfectants.
