Sleep Deprivation Can Cause Deaths
Studies have shown that people with irregular sleeping patterns have a higher mortality rate than those who get enough sleep on a regular basis.
More so, people who are deprived of adequate sleep appear to have a significantly higher risk of developing cardiovascular disease.
Second, during the night, various sleep cycles play a role in “consolidating” memories in the mind. If you don’t get enough sleep, you won’t be able to remember what you learned and experienced during the day.

When you don’t have enough sleep, it can limit your ability to comprehend things that yields into poor decision making and poor judgments. 
On the other hand, fatigue can make you forget things. Brain events known as “sharp wave ripples” are used to help consolidate memory, can make things you have learned easy to access and recall. These brain events also transfer short term information into the neocortex and hippocampus where they can become long-term knowledge. This transference occurs at the strongest rate during the deepest part of the sleep cycle, so cutting out a lot of deep sleep can hurt long term memory, which can lead to excessive forgetfulness.
5. Having Not Enough Sleep Can Make You Sick
According to the Mayo Clinic, studies show that if you don’t get enough sleep, it’s more likely that your body won’t be able to fend off invaders. It may also take you longer to recover from illness. Long-term sleep deprivation raises your risk of developing chronic illnesses like diabetes and cardiovascular diseases.
