“Why do we sleep? To clean our brains, say US scientists,” The Guardian reports. A US research team, studying mice, has suggested sleep helps clear the brain of ‘waste products’.
Although sleep is an intrinsic part of our lives, scientists are still uncertain why a good night’s sleep makes us feel better or why lack of sleep is bad for us.
Now a US research team claims to have found at least part of the answer. The study looked at whether sleep influences how the brain removes its waste products.
