People who suffer from a rare form of insomnia can die from lack of sleep. Scientists have long known, for instance, that lack of sleep is associated with weight gain. Another study also found that subjects ate significantly more snacks and carbohydrates after a night of only five and a half hours of sleep. We get about 25% less sleep than they did a century ago - and this isn't just a matter of having less energy. As ABC News reported, staying awake for just one night is enough to make you act as though you're legally intoxicated if you get behind the wheel. This shows just how crucial sleep is to your health. It is no less vital than food, water and air.
