“Sleep is a waste of time.” – Thomas Edison (Inventor of the lightbulb, possibly the single item most responsible for messing up our Circadian Rhythms.)
Though researchers don’t know the exact mechanism, it seems that chronic lack of sleep causes inflammation, elevates blood pressure and heart rate, and affects glucose levels, leading to a much higher stroke risk in the sleep-deprived.
