10 Horrible Things Pulling An All-Nighter Does To Your Brain

If HANGRY = hungry + angry, would that mean that SLANGRY = sleepy + angry? Asking for a friend.

You know the rules: Adults should get about seven or eight hours of sleep a night. EVERY NIGHT!

 

And teens need even more than that.

But sometimes that just… doesn’t happen. Maybe you’ve got a big exam to study for.

Or maybe you’re all about that party till the breaka-breaka dawn thing.

Or maybe you have a really bad read-the-internet-all-night-long issue.

Either way, pulling an all-nighter can do some funky and awful stuff to your brain. Like these 10 things:

1. You’ll have trouble remembering anything you tried to learn during the day (or night).

When you sleep, a part of your brain called the hippocampus replays what you’ve learned while you were awake, Dr. Charles Czeisler, chairman of the board of the National Sleep Foundation and chief of sleep medicine at Brigham and Women’s Hospital, tells BuzzFeed Life. This helps you encode those things you’ve learned into your long-term memory. No sleep, no long-term memory of those lessons.

And this is why pulling an all-nighter to study for an exam the next day isn’t very smart. “The better strategy would be to read the material during the daytime, and then sleep on it, because then you will actually encode that material into your long-term memory,” Czeisler says.

2. You’ll stay stuck on any complicated problems you can’t figure out.

Let’s say you’re staying up really late working on a problem set that you just can’t crack. The smart thing would be to go to bed now and try again in the morning. During REM sleep, your brain integrates new memories with other memories you’ve previously learned, Czeisler says. This can often result in insight: recognizing patterns and solving problems without even consciously thinking about it. If you pull an all-nighter, you miss out on that sweet, sweet subconscious insight.

3. Your circadian rhythm will be thrown off, making you feel like absolute garbage.

Every cell in your body contains its own circadian clock, and your hypothalamus acts as a master clock that keeps them all running in sync, Dr. Timothy Morgenthaler, president of the American Academy of Sleep Medicine and professor of medicine at Mayo Clinic in Rochester, Minnesota, tells BuzzFeed Life.

All day long, you are sending signals to your hypothalamus. Eating can be a signal, for instance. And light is another major signal, Morgenthaler says. When the hypothalamus receives these signals, it activates the release of hormones in your body that can make you feel hungry, sleepy, and more.

When you stay up all day and all night, though, your signaling gets completely out of wack — you’re seeing light when you shouldn’t be, and you’re eating at weird and unexpected times. That throws your cells’ circadian clocks out of sync, which makes you feel awful: “a vague sense of nausea, fatigue, lassitude, sleepiness,” Morgenthaler says.

4. Toxic metabolic refuse builds up in your brain.

Your brain burns a TON of energy throughout the day, which results in metabolic byproducts — refuse — left behind. (Think of soot as a byproduct of a car burning gasoline for fuel, Czeisler says; it’s the same idea). Every night, your brain works to repair and restore its neurons. But it can’t do that with all the refuse in the way, Czeisler says.

So every night when you sleep, your brain basically detoxes itself. The metabolites get flushed out through a lymphatic system that runs along the brain’s vasculature (called the “glymphatic system”). But when you don’t sleep, your brain doesn’t get to detox itself, the metabolites build up, and your brain cells don’t get repaired.

5. Your brain legit stops functioning as well as it normally does.

As you stay awake longer and longer, your brain becomes less and less efficient at burning energy, Czeisler says. That’s because your brain uses molecules called adenosine triphosphate (ATP) to help it burn fuel. The longer you stay awake, the more ATP you use, and the less there is left to help you metabolize energy. With less ATP available, you’re not as efficient as you could be.

You need to sleep to replenish ATP molecules. So when you don’t sleep… your brain is not being as efficient as it can be. Meaning it just won’t work as well in some big ways. For instance:

6. Your judgment will go out the window.

When your brain becomes less efficient burning energy, that can impact your prefrontal cortex. That’s the part of the brain responsible for good judgment and making smart decisions. When your prefrontal cortex stops working well, your ability to make smart choices and not be a totally impulsive maniac gets compromised.

7. So will your ability to process sensory information.

This can also impact your thalamus and the parietal cortex, both parts of your brain responsible for integrating sensory information, Czeisler says.

8. You’ll be moody as all hell.

 

“After just one night of lost sleep, people have moodiness problems,” Morgenthaler says. “They become crabby and not stable emotionally.”

9. You could suffer from a “sleep attack,” where your brain forces you to pass out in spite of your every intention not to — which can be deadly.

 

Throughout the day, as ATP molecules are used to burn energy, adenosine byproducts get left behind. As the adenosine levels build up, that sends a stronger and stronger signal to your brain that you need sleep. Once it hits critical mass, that can trigger a switch in your brain that forces you to fall asleep immediately and involuntarily. “It’s almost like fainting, but it’s an involuntary sleep attack,” Czeisler says.

During a boring lecture, this isn’t a big deal. But if you’re driving a car, it just takes a few seconds to veer off the road or into oncoming traffic, killing yourself or others. “These types of accidents are much more likely to have a higher fatality rate than other types of accidents,” Czeisler says. “If you’re drunk, you’re at least moving the steering wheel. But when you fall asleep, you don’t take any evasive maneuvers and you just sail right into whatever you’re about to hit.”

10. You will drive like a drunk person.

 

Even if you don’t fall asleep behind the wheel, you’re still a danger to yourself and others after pulling an all-nighter. “If you’ve been awake for 24 hours, your performance is as impaired as if you were legally drunk and had a 0.1 BAC,” Czeisler says.

And here’s a fun fact:

“Chronic sleep deprivation is more dangerous” in a number of ways than not sleeping for a night or two, Morgenthaler says. More on that another day.

correction

The longer you stay awake, the more you use up available ATP molecules for fuel. An earlier version of this article misstated that the molecules themselves get degraded into less complex sources of fuel.

Pop Tart liberation: Maryland state senator proposes ‘Toaster Pastry Gun Freedom Act’

Maryland kids will soon be able to eat Pop Tarts in peace.

It's not a gun. It's a tax – I mean, a pastry. "‘Toaster Pastry Gun Freedom Act’ proposed in #Maryland" http://t.co/yyXuhnzeOs

— Pillage Idiot (@pillageidiot) March 10, 2013

A Maryland state senator has proposed a bill that would prevent kindergarten students from being punished by school officials for crafting a Pop Tart into the shape of a gun.

“I just kept biting it/ tore off the top/ and it looked like a gun,” [said] 7-yo.“But it wasn’t,” he astutely added. http://t.co/xhYxgLWTBM

‘Can’t imagine’: Dana Perino and Ari Fleischer amazed by what’s in these Hillary-related emails

We already know some emails that have been released by the State Department show a very cozy relationship between members of the press and Hillary Clinton’s office when she was secretary of state.

Another email obtained by Gawker demonstrates how Philippe Reines, aide to then-Secretary Clinton, got Marc Ambinder of The Atlantic to publish favorable comments about Hillary:

Armbinder asked Reines for an advance copy of a speech Hillary Clinton was to deliver, and Reines agreed provided three demands were met. The first two concerned what Armbinder should write in his article, and the third demand was “don’t say you were blackmailed.” All demands were met.

Former Bush press secretaries Ari Fleischer and Dana Perino can’t believe it:

US Embassy evacuated? Here’s a spin suggestion, Obama. And some hard truth

http://twitter.com/#!/baldingschemer/status/477139841579110400

As Twitchy readers know, President Delusional says we can rest easy because al-Qaeda is on the run. Top men are on the case and stuff!

But how will they spin the evacuation of the U.S. Embassy in Baghdad? Iowahawk, being a giver, has an idea.

http://twitter.com/#!/iowahawkblog/status/478540421564346368

Of course, it could also be golf-related, right Barry?

Heartbreaking.

An exit hard truth for President Dangerously Incompetent:

Steven Crowder takes on Lena Dunham and “rape culture” [video]

http://twitter.com/#!/ChrisLoesch/status/522236102988820480

The left is obsessed with taking strong words and robbing them of their real meaning. “Racism” and “hate” are now applied to simple disagreement. With all the talk condemning “rape culture” are they minimizing the real crime of rape? Steven Crowder tackles the issue (and —shudder— plays Lena Dunham again) in his latest video.

New video up tonight! Will be taking @lenadunham to task and addressing our plaguing "rape culture" problem.

Another outrageous headline obscures violence against Israelis

We at Twitchy have for quite a whilebeen compiling headlines that report the deaths of Palestinians while omitting any context usually that the Palestinians were killed by police during an attack. Yair Rosenberg, senior writer for Tablet Magazine, noted one of these heavily truncated headlines today on the CBS News web site.

That’s not that far off from Al Jazeera English’s take.

So, could we get a little more detail on actually happened?

The Associated Press reports that the three Palestinians who were killed were armed with automatic weapons, explosive devices and knives, and managed to kill an Israeli security officer and seriously wound another before beingshot by police. Police then defused the explosives the attackers were carrying.

While security officers stopped one of the three men to check hisID, the other two drew guns and knives and attacked two female officers. Hadar Cohen,19,later died.

Update:

The Times of Israel noted the outrage on Twitter, as well as the second attempt at a headline by CBS News.
