Hi gang.
Now we're going to talk about sleep disorders in terms of impacts on states of consciousness.
If you have a sleep disorder, it can definitely impact your consciousness.
It can lead to an altered state.
So we're just gonna talk about the really big ones, the first one being insomnia, which
is either the inability to fall asleep, the inability to stay asleep, or you could be
one of the one's who has both the inability to fall asleep and the inability to stay asleep.
In insomnia, what happens because you can't sleep enough, you don't get enough of the
cycles of sleep between 2 and 5, bouncing up and down all night, that allows you to
get the mental restoration that you need in order to function properly.
And that can lead to an altered state.
Now somnambulism, which is a fancy way of saying sleep walking, and sleep talking take
place during stages 3 and 4, deep sleep.
For the most part, these are not issues.
For people who are sleep talkers, you can have conversations with people in the middle
of the night.
They will not remember them the next morning because they're in deep sleep.
So their brain is not really there.
Sleep walkers, same thing.
Tends to not be a problem unless the person is putting themself in danger, unless the
person is walking down the middle of the street, unless the person is driving their car while
they're still asleep.
Then it becomes a problem.
In those situations, wake the person up.
They may be groggy.
They may be disoriented.
They may be unaware of what's happening because they are in deep sleep when they're sleep
walking.
But them being dizzy and confused is better than them being injured.
Now, sleep walking and sleep talking - remember that takes place during deep sleep - which
is exactly what sleep terrors and night terrors are.
If you can think of it this was - sleep terror and night terror is basically sleep walking
and sleep talking a scary movie.
The person's brain is not really online, not functioning.
Their brain is kinda gone.
Their body is acting out what looks like a scary movie.
People in sleep terrors/night terrors, because they're in deep sleep, very difficult for
them to wake up.
If you do manage to wake them up, they're going to be disoriented and they're not going
to realize they're yelling and screaming woke up the whole family.
Now sleep terrors/night terrors we believe are due to neurological immaturity, so it's
quite possible that people can grow out of it.
It's also quite possible for the neurological issue of sleep terrors/night terrors to run
into adulthood, especially in families where there is the predisposition.
Now sleep terrors/night terrors completely different than nightmares.
A nightmare takes place during stage 5, REM sleep, when you are dreaming.
People who are dreaming and having bad dreams, they will wake up, whether a child or an adult.
They will figure out how to get comforted.
They may not go back to sleep, but they are aware that it's a dream because they were
in the sleep [dream] cycle.
People in the sleep terror/night terror, acting out a scary movie, it's not a dream.
If you wake them up, they will not understand why.
Narcolepsy is the sudden and overwhelming urge to go to sleep, usually due to excitation.
It's a neurological disorder.
Someone gets really excited, they fall asleep.
The lady on the right was being interviewed.
Must have been a very exciting experience because she all of a sudden fell asleep.
The dog in the vet's arms on the left, awake.
All of a sudden the dog gets excited - Boom.
Again, it's a neurological disorder.
You get overly excited, your body's reaction is to shut down.
It can be controlled with medication for some.
Unfortunately for some people with narcolepsy, they have restrictions on their lives.
There are some careers that they cannot do and there are some things they cannot do.
For example, driving may be something they never get to do because all of sudden falling
asleep when you're overly excited while you're driving gets very dangerous to you, the narcoleptic,
and very dangerous to everyone else on the road.
Now the last sleep disorder that we're going to talk about that can definitely impact your
levels of consciousness, your awareness, is sleep apnea.
What happens in sleep apnea is that someone transitions from light sleep to deep sleep,
they stop breathing.
And if you look at the picture on the left, you will see the tongue kind of falling down
and blocking the back of the throat.
The person cannot breathe.
And when you cannot breathe, you gasp [gasping sound], taking a big breath which brings you
from deep sleep into light sleep.
That means you don't get the cycles of sleep that you need.
You don't get to go from stage 2 to 5, back to 2, back to 5 all night long.
You don't get the restoration that comes from those cycling.
Some people with sleep apnea are more likely to have high blood pressure, higher risk of
heart disease, higher risk of stroke, high risk of kidney disease.
Also more likely to make mistakes or have accidents because they're not getting the
restoration.
Now fortunately, if you look at the picture on the right, there are remedies for sleep
apnea.
That is the CPAP system, and what they have found is if they can force positive air into
the nose and sometimes the mouth - in this case, the picture does only include the nose
- of a person with sleep apnea, it prevents their throat from being blocked.
They sleep all night long.
They can get those restoration cycles of sleeping, and they can actually reduce their risks for
high blood pressure, heart disease, stroke, and also reduce their number of accidents
and mistakes.
So those are the basic sleep disorders that can interfere with your ability to function
properly.
So thank you.
Bye-bye.
