November 1st we turn our clocks back and get an extra hour of sleep, but why is that sleep so important?
Lack of sleep clearly affects our thinking, or cognitive, processes. A sleep-deprived brain is truly running on four rather than eight cylinders. We’re much more likely to make errors. It’s because the brain’s engine hasn’t been replenished.
Sleep deprivation also affects us physically. Our coordination suffers. We lose our ability to do things with agility. Sleep improves muscle tone and skin appearance. With adequate sleep athletes run better, swim better and lift more weight. We also see differences in immune responses depending on how much someone sleeps.
