Not enough sleep can make you fat and grumpy. And that’s not all.
Sleep deprivation attacks your physical and mental health, which is why it has been used as a form of torture throughout history.
When your body doesn’t get enough sleep, you run a higher risk of getting type 2 diabetes, heart disease and dying early. Studies show people who sleep 5 hours or less a night increase their chance of early death by 15%. Lack of sleep also helps to make you fat, because it revs up your appetite.
From a mental health point of view, lack of sleep puts you in a bad mood. Your body releases too much of the stress hormone cortisol, which makes your grumpy, irritable and anti-social. Studies show that chronic lack of sleep contributes to mood disorders, such as depression.
Most of all, sleep deprivation makes you tired, intolerant and exhausted.
