Did you get enough sleep last night? If you're like most Americans, probably not. You might feel pretty good after six hours of sleep and a strong cup of coffee, but the physical and mental toll of sleep deprivation is high.
We become more impulsive and less mentally agile, and we make more mistakes. Long term, lack of sleep (six hours or less per night) can mess with mood, hormones, and immune systems, and it can increase our risk for diabetes and cardiovascular disease.
