America’s Sleep Deficit

Is enormous:

Short sleep duration (average ≤6 hours per 24-hour period) was reported by 30.0% of employed U.S. adults (approximately 40.6 million workers) 

Why this matters:

Sleep deprivation not only lowers productivity, but is also associated with accidents (a fifth of all vehicle accidents were linked to drowsy driving), and adverse health effects, such as heart disease and obesity.
