You’d think that feeling like a dry-eyed, gummy-mouthed zombie at work all day would be a good enough reason to go to bed at a reasonable time, but frankly, that’s what coffee is for. But, if you’re trying to motivate yourself to get more sleep, science has got your back:

According to recent research at the Radiological Society of North America, sleep deprivation messes with your heart, and not just in the nebulous, long-term-consequences kind of way.
Here’s the part that will make you want to actually listen to your mom and adopt a normal sleep schedule. Researchers found that after being deprived of sleep at work, participants showed an increase in systolic strain, blood pressure, and heart rate, and they had elevated levels of hormones associated with stress: cortisol, thyroid stimulating hormone, FT3, and FT4.

Aside from feeling exhausted, lack of sleep has been shown to impair your thinking and increase your risk for potentially deadly events like a heart attack or stroke. Some people experience hallucinations when they go without sleep for too long. It’s not known whether sleep deprivation can kill you for obvious reasons, scientists can’t test this out but a research had been conducted with rats in 1989. 

According to the National Heart, Lung, and Blood Institute, teenagers need nine to 10 hours of sleep per night, and adults require seven to eight. Fortunately, most effects of sleep deprivation are reversible, and avoiding it is easy enough: Less coffee and more sleep.
