We all know what it’s like to get a lousy or short night of #sleep: Tempers shorten, snacks become more tempting, attention gets harder to sustain.
Poor sleep has been linked to heart disease, diabetes, obesity and depression. Newer research has drawn connections between bad sleep and Alzheimer’s. A study released last year showed that the better 700 participants slept, the less likely they were to develop Alzheimer’s over the next 3.5 years.
Scientists don’t understand exactly why we sleep, but every creature does it, so “that tells you there’s something really profoundly necessary” about it, Francis Collins, director of the National Institutes of #health, said at the premiere of the show this month.
A growing body of research suggests that during sleep, the brain appears to flush out harmful chemicals such as the beta amyloid that builds up in Alzheimer’s.
