If you snooze, do you really lose?
Many people, especially teenagers and college students, do not get enough sleep during the night because of either school work, sports, or other activities. This is a growing problem especially with todays technology. Many teens don't think that its a problem to stay up late and only get 5 hours of sleep a night, but this little thing can turn into major health problems, physically and mentally.
- Drowsiness can slow your reaction time just as much as drunk driving
- When you are sleep deprived its equivalent to driving with a blood alcohol content of .08%, which is illegal
- NHTSA estimates that fatigue is the cause of 100,000 crashes and 1,550 crash-related deaths a year in the U.S.
- This problem is greatest for people 25 or under, but it can happen at any age
Dumbs You Down
- Lack of sleep impairs attention, alertness, concentration, reasoning, and problem solving
- If you do not get enough sleep, you won't be able to remember things that you learned or were told previous days
- Various sleep cycles play a huge role in consolidating memories, i.e. the more you sleep, the more you will remember
- Less sleep=less sharp wave ripples, which trigger memory in the brain

- Lack of sleep doubles the risk of early death and cardiovascular disease
- Breaks down immune system
- Restless Legs Syndrome-also known as Willis-Ekbom Disease is a overwhelming urge to move the legs when they are at rest
The glymphatic system, which is the pathway that rids our central nervous systems of waste, is much more active during sleep. The spaces between cells in the brain increase during sleep; this means that there’s far more room for fluid to slip in among the cells, pick up waste, and float it out toward the liver. Also, the reason why the glymphatic system works much faster during sleep is because it has access to more energy.
The photo on the left shows what a brain looks like when someone has been in a deep sleep, and the right shows someone who has been in a light sleep, and the waste build up that it causes.
