Transcript of Sleep Deprivation
Sleep deprivation is the condition of lack of sleep. It is very common among North Americans. It is a serious issue, experiments have been conducted and lab animals have died from sleep deprivation. The lack of sleep can result in effects such as drowsiness, clumsiness and day time sleeping.
Consequences of Sleep Deprivation
Did you know sleep deprivation can be fatal?
The major effect of sleep deprivation include:
Brain damage and cognitive function, and growth.
Slow reaction time, like a drunken person.
Increased chances of injury due to slow reaction time.
Think you are sleep deprived? Do you have the following symptoms associated with sleep deprivation?
relies on snooze button
have hard time getting out of bed
feel sluggish in the afternoon
need to nap throughout the day
the urge to sleep in on weekends
get drowsy after heavy meals
How much sleep should we get?
According to this chart, teenagers are supposed to get 8.5 to 10 hours of sleep per night.
But how much sleep do we actually get?
We conducted a survey in the class and found that most people in this class get 7-8 hours of sleep, while many others only get 4-6 hours of sleep.
ONLY TWO PEOPLE
are getting the healthy amount of sleep, which is 9 hours of sleep per night.
This just shows how much sleep most of us lack.
When you do not get enough sleep, you wake up feeling tired and groggy. So the alarm clock goes off in the morning, it’s very tempting to hit the snooze button.
BUT DON’T DO IT!
You might think that extra 10 minutes can help you wake up and feel less tired, but it actually makes you even more tired, so you will end up feeling even worse than before! This video will show you why.
Sleep deprivation and the snooze button
So basically, even though you might think that hitting snooze will give you a chance to finish your natural sleep cycle,
that’s not what happens
. When you hit snooze and fall back asleep, the sleep cycle
restarts all over again
. So when the alarm goes off again, you’re more likely to be at an even deeper, earlier part of your sleep cycle, which will result in you feeling
even more tired
than you did before the snooze.
What is the reason for people not getting enough sleep?
Different people have different reasons for sleeping late. People may stay up late due to videos games, homework, social interaction, etc. One of the reasons that does correlate to sleep deprivation is workload.
A source we found conducted
a survey on the difference in hours of sleep between
AP students and students in regular classes.
The survey states that
students in Advance Placement
will receive significantly
than those in regular classes,
due to heavier workloads.
Their data is obtained from 15 public high schools, 2086 students participated.
Some examples of harmful accidents caused by sleep deprived workers include the 1979 nuclear accident at Three Mile Island, the massive Exxon Valdez oil spill and the 1986 nuclear meltdown at Chernobyl.
This is a photo of the Exxon Valdez oil spill.
The third mate failed to properly maneuver the vessel, possibly due to fatigue or excessive workload.
one of the most environmentally devastating cases
, killing many seals, sea birds and marine life
Is it okay to oversleep?
When it comes to sleep, can you have too much of a good thing? It's true a good night's sleep is very important and essential for health. But oversleeping is actually a medical disorder. It has been linked to a host of medical problems, including diabetes, heart disease, and increased risk of death.
SO, SLEEP TIGHT
...But not too much!
