Why Does Sleeping In Just Make Me More Tired?

We’ve all been there: It’s been a long week at work, so Friday night, you reward yourself by going to bed early and sleeping in. But when you wake up the next morning (or afternoon), light scathes your eyes, and your limbs feel like they’re filled with sand. Your brain is still lying down and you even have faint headache. If too little sleep is a problem, then why is extra sleep a terrible solution?

Oversleeping feels so much like a hangover that scientists call it sleep drunkenness. But, unlike the brute force neurological damage caused by alcohol, your misguided attempt to stock up on rest makes you feel sluggish by confusing the part of your brain that controls your body’s daily cycle.

Your internal rhythms are set by your circadian pacemaker, a group of cells clustered in the hypothalamus, a primitive little part of the brain that also controls hunger, thirst, and sweat. Primarily triggered by light signals from your eye, the pacemaker figures out when it’s morning and sends out chemical messages keeping the rest of the cells in your body on the same clock.

Scientists believe that the pacemaker evolved to tell the cells in our bodies how to regulate their energy on a daily basis. When you sleep too much, you’re throwing off that biological clock, and it starts telling the cells a different story than what they’re actually experiencing, inducing a sense of fatigue. You might be crawling out of bed at 11am, but your cells started using their energy cycle at seven. This is similar to how jet lag works.

But oversleep isn’t just going to ruin your Saturday hike. If you’re oversleeping on the regular, you could be putting yourself at risk for diabetes, heart disease, and obesity. Harvard’s massive Nurses Health Study found that people who slept 9 to 11 hours a night developed memory problems and were more likely to develop heart disease than people who slept a solid eight. (Undersleepers are at an even bigger risk). Other studies have linked oversleep to diabetes, obesity, and even early death.

Oversleep doesn’t just happen as a misguided attempt at rewarding yourself. The Harvard Nurses Study estimated that chronic oversleep affects about 4 percent of the population. These are generally people who work odd hours, have an uncomfortable sleep situation, or a sleeping disorder.

People who work early morning or overnight shifts might be oversleeping to compensate for waking up before the sun rises or going to sleep when it’s light out. Doctors recommend using dark curtains and artificial lights to straighten things out rather than medication or supplements. Apps like the University of Michigan’s Entrain can also help people reset their circadian clock by logging the amount and type of light they get throughout the day.

When you go to bed, your body cycles between different sleep stages. Your muscles, bones, and other tissues do their repair work during deep sleep, before you enter REM. However, if your bed or bedroom is uncomfortable—too hot or cold, messy, or lumpy—your body will spend more time in light, superficial sleep. Craving rest, you’ll sleep longer.

If everything’s just fine with your sleep zone but you still can’t get under the eight hour mark, you might need to go see a doctor. It could be a symptom of narcolepsy, which makes it hard for your body to regulate fatigue and makes you sleep in more. Sleep apnea is a potentially more serious disorder where you stop breathing while you slumber. It’s typically caused by an obstructed airway, which leads to snoring. However, in a small number of sufferers, the brain simply stops telling the muscles to breathe, starving the brain and eventually forcing a gasping response. In addition to all the other terrifying aspects of this disease, it’s not doing your quality of sleep any favors.

No surprise, drugs and alcohol might also be causing you to sleep too much, as does being depressed (In fact, oversleep can contribute to even more depression). But no matter what’s causing it, too much sleep is not good for your long term health. Rather than kicking the can down the road, try getting some equilibrium between your weekend and weekday sleep.

My body’s perpetually stuck in the 1 AM - 8 AM sleep cycle.

You seem to really not like DashCon. Is it, like, the worst-of-the-worst con? (I really don't know, the only ones I properly know of are ones like SDCC and NYCC)

DashCon is a first-year fandom convention for Tumblr users. It is happening this weekend and turning into possibly the largest convention kerfuffle anyone has ever seen.

The list continues but so far it’s only the con’s second day and it is quite literally the most dramatic, hysterically cringe-worthy convention debacle I have ever seen unfold.

Adding some updates as of 7/12 at 7:35 PM EST:

  • The game room consists of some tables, one TV, and one gaming console. No, really, that’s it.
  • DashCon proves they have possibly the worst PR team ever when addressing the WTNV cancellation. Instead of clearly explaining the situation, they say they “don’t want to get into it,” and then offer compensation for those who bought advanced seating tickets for the Night Vale show. What’s the compensation? An extra hour playing in the ball pit (which is really just a slowly-deflating children’s pool with some balls in it). Oh, and if there’s room, you may get one of the first-come-first-serve spots at the Time Crash concert happening tonight. Huzzah!
  • Most panels are completely disorganized. The “Name That Anime” panel was even handing out hotel mints as prizes for correctly answering questions like “what’s the anime where they fight with clothes!!!”
  • This still needs verification, but supposedly there are minors being let into the 18+ panels (like “BDSM 101”), which DashCon could easily get sued for allowing. Not that they have the money for it.
  • It’s been pointed out that as a Marriott hotel, the Renaissance would have required them to submit their full reservation payment 5 days in advance of the event. Therefore it’s very, very likely that the “$17,000 fundraising” was a huge scam. Because DashCon would’ve had to pay that money 5 days before this weekend or the event wouldn’t even be happening in the first place.
  • Furthermore, someone attempted to debunk the letter that DashCon posted to prove that the hotel asked for money. Not all their points are valid (i.e. “RE:” is commonly used for “Regarding”, not just in response to previous communication, and idk but this dude doesn’t strike me as an expert on internal Marriott stationary), but frankly the letter looks sketchy if only because 17000% 99% of it is whited out. Is it real? Is it fake? We just don’t know.
  • There has been no confirmation that the money donated in cash and via PayPal last night ever made it to the hotel (if that was indeed where it was intended to go).
  • People are demanding full or at least partial refunds. Needs verification, but purportedly DashCon has a list at the con where you can sign your name and the amount you donated to be refunded later. Which sounds like a totally effective and not at all easily-abused system. [Verified: x]
  • Attendees are either in denial saying this is the best con ever or they’re crying and having panic attacks. Welcome to Tumblr.

And as a bonus: DashCon originally ran an IndieGoGo campaign last year to raise $5,000 to start their convention. They raised $4,000. The campaign ended in April 2013 and rewards have still not been sent out (which consisted of tea bags, a couple business cards with your Tumblr URL on them, and if you donated $500+, some knick-knacks from Etsy).

More updates, as of 7/13 at 3:59 AM:

As always, if you can confirm or deny anything in these masterposts with proper validation, it’s greatly appreciated! I originally did the first one just to answer an ask I got, but as it’s blown up I figured I’ll keep doing it, since I’m captivated by the whole mess anyways. :’D

I’m heading to sleep now but I’ll do another update tomorrow once I’ve caught up on anything else that happens tonight! Hopefully no one dies. I’m not sure how else this con could get any worse.

And one last thing, just to clarify: my heart goes out to all you guys who paid to attend what you thought would be a fun convention and instead got this trainwreck. Even if it turns out that the $17,000 fee wasn’t a scam, remember that it is absolutely unacceptable for a convention to operate this way. I’m so glad that many of you have been able to see the positive in a bad situation and still managed to make friends and have a good time - but don’t forget to stand up for yourselves, too. A convention should never extort money from its attendees for any reason. Again, it’s great that you still made some good memories, but good memories alone do not make a good convention. Make sure your feedback is heard, especially if you want to see this con (or any future Tumblr-oriented con) have any hope of success.

Good morning! Here we are, July 13th, the final day of DashCon. So far, this is what’s happened as of 11:46 AM:

  • Supposedly this Tumblr user posted a full version of the letter from the hotel to DashCon staff. However, it is not real. If you’ll notice, the original letter as the amount due written as “$20,000.00” whereas in this version it’s only “$20,000”. The formatting also does not line up correctly. (Too bad it isn’t real, though, that’d be a riot.)
  • Gingerhaze revealed that Doug Jones has already left the premises.
  • Another witness account describes how DashCon “collected money in a bag” during the $17,000 debacle. They also took names on an email list to issue WTNV refunds at a later date. Who wants to take bets that said refund never happens?
  • This video shows the moment when it was announced that WTNV left the convention.
  • DashCon is making news headlines.
  • Staff tries to start rumors that WTNV was paid and left anyways. No one believes it.
  • People are debating whether or not out-of-state businesses require an Illinois LLP to operate within Illinois, or if they only have to pay a $500 registration fee (which we have no confirmation of DashCon doing so). Would any lawyers care to confirm/deny?
  • The act of offering extra play time in the ball pit as compensation for the WTNV tickets could easily turn into another lawsuit, as they did not originally charge an entrance fee for the ball pit, therefore giving it no comparable monetary worth to compensate for the purchase of event tickets.
  • Attendees and staff are attempting to start the conspiracy theory that 4Chan ruined DashCon.
  • Like Gingerhaze and WTNV, the BakerStBabes are also being forced to pay their hotel fees because DashCon refuses to cover the costs as originally promised. Admins are refusing their calls. You can read more about their experience here.
  • The artist and vendor hall has essentially cleared out.
  • Please note that dashcon-staff is a fake Tumblr account.
  • Finally, here’s a video of con admin Cain describing his experience during the $17,000 fundraising events of Friday night.
"Tokyo will be enveloped by darkness after 3 p.m. Large sparks will fly, scattered around the Shinjuku area. Use caution when leaving the house"

Yeah, not perturbing in the slightest. I mean, I don’t find it unsettling personally, but it certainly evokes images of a certain other event in recent American history.

Man, anime sure is in a sadistic stage nowadays, isn’t it?
