There are numerous reasons why sleeping is many people’s favorite activity. This peaceful part of our day is vital for both our physical and mental well being; it is a state of mind when we can dream, relax, restore our energy, etc. We often tend to think of our slumber as a very inactive and quiet activity.
But as you will see in our post today, that is not true at all. You will be surprised to learn how many things are actually going on in our body when we are having a doze. You do not need to worry though. All of the things are totally normal, helping your body to work properly once you are awake again.
As long-term sleep deprivation can have devastating effects on your health (see these 25 Scary Surprising Effects Of Sleep Deprivation), it is important to understand and appreciate your sleep. After all, we spend a whole third of our life sleeping.
Therefore, today’s post with things your body does while you sleep might come in handy as it will help you better understand what is going in our body while we slumber away. From bruxism and sleepwalking to exploding head syndrome and sleep apnea, here are 25 Things Your Body Does While You Sleep.
Your body temperature drops

Your eyes move

Your body jerks

Your muscles are paralyzed

Your skin repairs itself

The top layer of the skin is made of closely packed dead cells which are constantly shed during the day. In sleep, the skin’s metabolic rate speeds up, and many of the body’s cells show increased production and reduced breakdown of proteins. As proteins are needed for cell growth and repair of damage from factors like UV rays, deep sleep may indeed be beauty sleep.
Your brain forgets useless information

“We take in all this information all day long, and most of it is luckily forgotten,” says sleep specialist Christopher Colwell at UCLA School of Medicine. “If you remembered everything, it would fill up your brain, so a sorting process takes place during sleep.”
Your throat gets narrow

Your body secrets hormones

Your immune system is at its all-time high

It has been shown that sleep deprivation affects the immune system. One study showed that people who received flu shots and were sleep-deprived the next night did not create the antibodies required to protect against the flu. Therefore, if you notice the first signs of an infection, try to sleep as long as you can to give your immune system time to beat the illness.
You lose weight

While sleeping, you lose water through perspiring and breathing out humid air. This happens during the day too, but eating and drinking negates any weight loss. Therefore, having a good and long sleep is necessary for any diet to be successful.
Your mouth gets dry

You might grind your teeth

It is estimated that about 5% of people suffer from a bizarre condition known as sleep bruxism. This parafunctional activity manifests itself by excessive teeth grinding and may eventually lead to damage of the teeth. Scientists are not sure what exactly causes this condition, but they believe it might be a form of stress relieving.
Your body gets taller

Your blood pressure plummets

When sleeping, you experience what is known as “nocturnal dipping” of your blood pressure. If you’re otherwise fit, your blood pressure can drop by about 5 to 7 points with a good night’s sleep.
You might sleepwalk

Scientifically known as parasomnias, sleepwalking and other mid-sleep activities include behaviors, emotions, perceptions, and dreams that usually occur during the transitions between some of the sleep stages. Parasomnias are mostly harmless, but there have been cases when people injured themselves while sleepwalking.
You might get sexually aroused

Both men and women might get sexually stimulated while sleeping. As your brain is more active during sleep, it requires more oxygen. As a result, blood flow all over the body increases, causing swelling of genitalia. Interested in more cool sleep-facts? Take a look at our list of 25 Cool Facts About Sleep You Probably Didn’t Know.
You dream

Your brain makes decisions

A recent study has found that the brain can process information and prepare for actions during sleep, effectively making decisions while unconscious. In fact, your brain can even make important connections and discoveries while you are dozing.
You have gas

You won’t be happy to hear this, but during the night, your anal sphincter muscles loosen slightly, making it easier for the gases in your intestines to go out. The good news is that your (and everyone else’s) sense of smell is reduced while sleeping, so your farts will probably go unnoticed during the night.
You do a full toxin cleanse

You wake up without knowing it

You might stop breathing

You might hear an explosion

Exploding head syndrome is a rare benign condition in which a person hears loud imagined noises (such as a bomb exploding, a gunshot, or a cymbal crash) or experiences an explosive feeling when falling asleep or waking up. It is painless but frightening for the sufferer.
You might sleep talk

Your pain tolerance is higher
