- [Blocko] Hey there, welcome to Life Noggin.
I'd be willing to bet that we're all guilty
of staying up late and sleeping in,
at least once, or in my case many, many times.
I'm sure you know that getting a good night's sleep
is good for you and staying up all hours of the night isn't,
but oversleeping is also associated with health problems.
To help with this video,
I brought in a sleep scientist, Juniper.
- [Juniper] Yeah, about that,
I kinda lied to get on this episode.
I just stream video games.
- [Blocko] Oh, so do you know anything about sleep?
- [Juniper] Well, I don't get a lotta sleep
almost every night and I'm constantly tired.
- [Blocko] You're hired.
So, which is worse for your health staying up
or sleeping in?
When we're lucky they go hand in hand,
you sleep in after staying up late,
but that's not often possible.
Especially when you have work or school in the morning.
You're usually missing out on sleep
when you stay up or under sleeping.
So let's see how this compares to sleeping too much.
Oversleeping.
- [Juniper] Deciding when you go to sleep,
may not be entirely up to you.
Scientists have found that your sleep chronotype
or internal clock is tied to certain genes,
but how much sleep you get is another matter.
And there is a general consensus that missing out
on your required sleep can lead to a lot of health issues.
So Blocko, does everyone need a certain amount
of sleep each day?
- [Blocko] According to the National Sleep Foundation,
this sleep need ranges from 17 hours for newborns
to seven hours for adults,
with teenagers and young adults needing
around nine hours of sleep a day.
Of course, this is gonna vary depending on the person.
- [Juniper] Is that nine hours of sleep thing
like mandatory or?
- [Blocko] Or people that regularly miss this mark are
at a higher risk of developing psychological, neurological,
gastrointestinal and respiratory disorders
as well as heart disease.
- [Juniper] So that's a yes.
- [Blocko] In a 2013 study of 6,500 patients,
researchers found that people who typically slept less
than six hours a night were more likely to have a stroke,
congestive heart failure, and a heart attack compared
to those who slept six to eight hours a night.
Lack of sleep had also been linked to type two diabetes.
Without a good night's rest,
our hormones struggled to regulate processes
like hunger and weight control.
And researchers have found that when you miss out on sleep,
less insulin is released after you eat.
Insulin is a chemical that helps your muscles, fat,
and liver cells absorb sugar,
where it's stored until your body needs energy.
- [Juniper] But that doesn't mean
that oversleeping is good for you.
That same 2013 study on heart disease also found
that subjects who slept for more than eight hours a night
were at higher risk for coronary artery disease and angina,
which is the medical term for chest pain caused
by reduced blood flow to the heart
and like losing sleep,
oversleeping can also increase your risk
of type two diabetes though the reasons
for this are less clear.
- [Blocko] Aside from all these health issues,
what are the chances that you'll actually die
from either staying up or sleeping in?
Well, I hate to be that guy, but it could happen.
- [Juniper] Did you say die?
Why is everything you talk about so dangerous?
- [Blocko] Ah, I see you've been subscribed
to this channel for a while, huh?
Due to the higher prevalence of all these health problems,
both those who go to sleep late and sleep in,
have a greater risk of death.
A meta analysis combining the data of 16 studies
and over 1 million subjects found that compared to adults
who sleep the normal seven to eight hours,
those who slept less than seven hours a night
had a 12% greater risk of death.
And those who slept more than eight hours
had a 30% greater risk.
So do yourself a favor and try your best
to get your required amount of sleep.
Chances are you probably have something going on
in the morning and you're gonna have to wake up early.
So don't stay up too late.
It seems like it's really bad.
I hope this helped you, Juniper.
Maybe now you'll get some more sleep.
Juniper?
- [Juniper] Huh, did you say something?
- [Blocko] Are you streaming during this video?
- [Juniper] Oh yeah, but don't worry,
if someone donates 100,000 bits,
I get to sleep for 25 minutes.
- [Blocko] Okay, well, I don't know what that means,
but tell me how much sleep do you actually get?
Be honest.
Let me know in the comments section below.
