Sleep deprivation is a silent epidemic. Since the invention of the light bulb, we have obtained less sleep than our ancestors, prioritizing work, school, socializing, sports, screen time – just about everything – over sleep. Sleep is viewed as compressible, something that can be made up at any time, but rarely is. Most believe this poses little risk. Unfortunately, they could not be more wrong. The truth is, an adequate amount of good-quality sleep is critical to good health. Lack of sleep leads to deadly crashes, reduces productivity, and harms quality of life. Insufficient or disordered sleep can increase risk for ADHD, depression, heart attack, stroke, arrhythmia, heart failure, and early death.
