Why not sleeping wreaks havoc on your body

Whether it was because you were studying for a test or binge-watching a show on Netflix, we've all pulled all-nighters.

Yet, not sleeping can be very damaging to your health.

One study found that for every 24 hours you don't sleep, your energy and performance decreases by 25 percent.

That's because even though your body is awake, parts of your brain shut down and take their own nap.

Not getting enough sleep is the equivalent of being drunk. One researcher found only getting five hours of sleep a night or pulling an all-nighter is the same as drinking four or more drinks.

You're also more likely to get sick. One study found that people who don't get enough sleep at night are four times more likely to catch a cold.

And while one night of sleep is bad for your health, sometimes it happens. Things get steadily worse the longer you go without giving your body and mind a rest.

After four days of not sleeping, you might begin to hallucinate and become paranoid that someone is after you. Memory function begins to decrease and you start having trouble concentrating.

So even if that last episode on Netflix is calling your name, turn it off and get a good night's rest.

Your body and mind will thank you.

Sleep eating

Nocturnal sleep-related eating disorder is characterized by people sleep walking to their kitchens and eating. Often times, they have no recollection of it, and only realize when they discover messes and missing food.

Sometimes, the patient has severe weight gain and other health issues attributed to the disorder. 

Frequently, the foods eaten are high in fat, sugar and carbohydrates. Furthermore, people with the disorder create bizarre food combinations with the items they have access to in their kitchen. 

Acting out their dreams

REM sleep behavior disorder physically play out their dreams, moving their bodies or even getting out of bed.

Their dreams are so vivid and real, that during REM sleep, which normally restrains your muscles, your body still flails. 


It is possible to experience auditory, visual, tactile and olfactory hallucinations, as many times, the person cannot tell what is part of a dream and what is part of reality. 

The hallucinations often happen in the stages right before sleep (hypnogogic) or after sleep (hypnopompic). Hypnogogic can be associated with sleep paralysis and a fearful sensation. 

Hypnopompic is usually associated with dreams and 'feeling a presence in the room'. 

Sleep sex

Called 'sexsomnia', it falls under the category of parasomnia, the stage right before you fall asleep.

When a person has this disorder, they oftentimes engage in sexual acts with a partner or themselves, while asleep. They have no recollection of it. 

It is more common for people who normally are affected by other sleep disorders, or those taking sleep medications.

Sleep texting

Apparently, more and more people are sending texts in their sleep. 

"It is very common for people to do things in their sleep that they do repeatedly during the day," said a neurologist in an article to BBC. 

Understandably, the texts make little sense to the person after they've woken up. 

Exploding head syndrome 

It occurs when you're about to drift off into sleep, and suddenly a loud noise goes off in your head. 

Another parasomnia event, exploding head syndrome sounds similar to a clap of thunder or bomb. However, it sounds as if the noise could be heard by everyone, but in reality, it's internal.
