People will often cut back on their sleep for work, for family demands, or even to watch a good show on television. But if not getting enough sleep is a regular part of your routine, you may be at an increased risk for obesity, diabetes, high blood pressure, coronary heart disease and stroke, poor mental health, and even early death. Even one night of short sleep can affect you the next day. Not surprisingly, you’re more likely to feel sleepy. On top of that, you’re more likely to be in a bad mood, be less productive at work, and be involved in a motor vehicle crash.
