Prof. Laura Lewis and her colleagues have discovered that momentary lapses in attention that often follow a bad night’s sleep are caused by the brain attempting to flush fluid out of its system, reports Carissa Wong for New Scientist. “If you don’t have these waves [of fluid flowing] at night because you’re kept awake all night, then your brain starts to kind of sneak them in during the daytime, but they come with this cost of attention,” says Lewis.
