25 Things Your Body Is Busy Doing While You're Asleep

Temperature Drop

Temperature Drop

Most of the muscles in your body are busy doing absolutely nothing and so you're not burning too many calories, right? So it only makes sense that your body temperature drops way down. Perhaps that's why we have blankets on the bed...

Wandering Eyes

Wandering Eyes

You probably don't remember it at all, but when you're asleep, your eyes roll and dart about all over the place under your eyelids, according to whichever state of sleep you happen to be in throughout the night.

Jerk and Twitch

Jerk and Twitch

In the initial stages of sleep, early in the night, it's not uncommon for your body to twitch and jerk about. On occasion, this will even be enough to wake you up. You know those times where you wake up suddenly (often feeling like you're falling).

Paralysis

Paralysis

Perhaps a matter of convenience, your muscles are paralyzed during your sleep (for the most part - especially during dreams). If they weren't the experts tell us we'd probably act out our dreams and of course, we don't have to mention why that would be a problem.

Your Skin Grows

Your Skin Grows

The dead skin that falls off your body throughout the day (yes, it does happen) repairs itself at night. In fact, many of your body's cells do most of the rejuvenation during sleep.

Your Brain Decides What To Throw Away

Your Brain Decides What To Throw Away

At night, during sleep, your brain catches up with itself and goes about discarding information that it deems you not to need. Of course, you take in so very much throughout the course of an average day and if your brain retained it all, you'd fill your head up with junk (isn't reality TV enough?).

Your Throat Narrows

Your Throat Narrows

The good thing about the muscles in your throat is that they don't experience the same paralysis as most of the other muscles. It's a good thing too, or you'd be dead, of course. They do relax a little, however, which is thought to result in snoring in some people.

Hormone Secretion

Hormone Secretion

No matter how gross that sounds, you'll have to trust me when I assure that hormone secretion is a good thing. Your body produces hormones during your sleep that is vital to regeneration of your cell reproduction and regeneration.

Sleep Vs Infection

Sleep Vs Infection

Your immune system works best when you sleep. In fact, if you don't sleep your immune system will begin to suffer. The moral of the story is; if you're not well - sleep.

You Lose Weight

You Lose Weight

Great news, right? Does this mean that if you want to lose weight that all you need to do is go to bed and stay there until you're thin? No, of course not. However, it is true that weight loss takes place during sleep. It's basically because the same thing happens as during the day - you lose water through perspiration - the difference is that you're not drinking or eating to replace it.

Your Mouth Gets Dry

Your Mouth Gets Dry

Have you ever thought why you need saliva? Probably not. But it has something to do with helping you to eat the food you put in your mouth. Your body produces less saliva when you're sleeping because hey, who sleep-eats?!

Grinding Teeth

Grinding Teeth

Everybody has heard of grinding teeth in one's sleep, whether they actually do it or not. However, experts tell us that only 1 in 20 people experience what is known as "bruxism" - a severe grinding of the teeth that is thought to be associated with stress.

You Get Taller

You Get Taller

...And then you get shorter during the day. Gravity is to blame. It pushes your vertebrae closer together.

Nocturnal Dipping

Nocturnal Dipping

...is the term which describes what happens to your blood pressure during sleep. Quite simply, it drops way down.

Sleep Walking

Sleep Walking

This parasomnia affects some people during instances which are mostly harmless, however, they have been known to cause serious injury and even death on occasion. When I was younger, my housemate walked in to my room (apparently asleep) and took a piss on my bed. He didn't remember a thing of it the next day - but I did.

Arousal

Arousal

You don't have to be a 13-year-old boy to experience sexual arousal during your sleep (although that will considerably increase your chances). Because your brain is so active while your body rests, it can cause blood to flow to the genitals of either man or woman.

Dreaming

Dreaming

Okay, so we knew about this one. One of the things we associate most with sleeping is dreaming. They mainly occur in the first stages of sleep when your brain is most active, and most of us have around four or five dreams during sleep each night. Despite the fact we do know this much, it is still not fully understood why we have them in terms of their absolute function.

Your Brain Has Time To Process Stuff

Your Brain Has Time To Process Stuff

Dreams may indeed have something to do with the brain processing what has gone on during the waking hours, and may even be a waste disposal for confused thoughts our brains don't really need. Either way, it is true that your brain does a lot of it's processing and even decision making while you're unconscious.

You Fart

You Fart

It's a happy convenience that your sense of smell is reduced while you're asleep because you will fart more often than you usually do. This is because the muscles of your anal sphincter are more relaxed than when you're awake.

Toxin Cleanse

Toxin Cleanse

Sleep allows both body and brain alike to cleanse themselves. This is just one of the many reasons you shouldn't' deprive yourself of sleep to work more or for any other reason - you'll simply wind up less productive, thereby defeating the purpose.

Brief Awakening

Brief Awakening

You will wake up during your sleep during the different stages of your sleep, however, it's usually so brief that you don't remember having woken up at all.

Sleep Apnea

Sleep Apnea

If you suffer from this one then you are most certainly not alone. Sleep apnea is when a person stops breathing during sleep, for a period of anywhere between a couple of seconds to a couple of minutes.

Exploding Head!

Exploding Head!

Much rarer is the condition known as exploding head syndrome. Fortunately, it is not accompanied by any pain of any sort, but the sufferer might be awoken by a loud explosion sound, or it could even sound like a gunshot. As you can imagine, despite the fat it doesn't actually hurt them, it can be quite scary and unsettling.

Sleep Talking

Sleep Talking

This is a form of parasomnia, as sleep walking is. Most of the time it is incoherent babble and probably just a byproduct of equally bizarre dreams.

You Have A Higher Pain Tolerance

You Have A Higher Pain Tolerance

Your tolerance for pain is higher when you're asleep. Your nerves can't receive such signals when your body is paralyzed like that. In fact, there's a lot of things you can't do very well when you sleep; hear, see, smell, etc.
