And if you’re going to be out of action for a predictable period of time every day, says Foster, you might as well use that time for something. “Cells and bodies have to do a whole raft of housekeeping functions,” he says – clearing out toxins, bringing in new fuel – and brains, especially, have a lot to deal with. “All this information is streaming in during the day: it needs, at some stage, to be processed and packaged.” A recent paper found that one activity of sleep is clearing a toxin called beta-amyloid protein, which is associated with Alzheimer’s disease, out of the brain. Not all sleep scientists would agree with him, but Foster thinks that the correct evolutionary answer to the question “why do we sleep?” is: lots of reasons. |
