Sleep deprivation is exactly what it sound like: you are deprived of sleep. If you have experienced sleep deprivation, you know how brutal it can be. Chronic sleep deprivation is when you are deprived for long periods of time – at least a month or more. This differs from acute sleep deprivation, that is short lived and often has a very specific cause. Chronic sleep deprivation will most certainly make life miserable for you, and can negatively impact those around you as well.
