How Does Poor Sleep Affect Your Nervous System?

Of course, we have all, at some point, missed out on the recommended dose of 7-9 hours of sleep every night, and the potential reasons include more serious factors like exam preparations to silly ones like finishing a movie series or a late night out with friends.

Whatever the case, you can attest to how tired you felt the day after. Perhaps it wouldn’t be such a big deal if the only penalty for staying up late is the grogginess or grumpiness felt the next day, but there are long term, not-so-lovely consequences too; including a deterioration in your nervous system’ health!

The nervous system is made up of the central nervous system and the peripheral nervous system. In this article, you learn how lack of sleep affects both divisions of your nervous system.

Central Nervous System

This is the control center of your body. It consists of the brain and the spinal cord.  Here is what happens to your brain when you deprive it of enough sleep:

You get distracted easily.

You might notice a sluggish feeling when you miss sleeping; it’s really not a good feeling. However, your brain cells get the feeling too- they become sluggish. So instead of making the perfect coffee in the morning; you end up with a weak coffee. You would find it hard to concentrate on a particular activity; instead, you engage in multitasking- which may not be good for your productivity.

Surely, not only your productivity is affected- your cognitive ability might suffer these consequences as well. 

Memory Lapses

A new study confirms that lack of sleep diminishes the ability of brain cells to communicate effectively leading to mental lapses and forgetfulness.

In the study, 12 patients with epilepsy who, as part of the preparation for surgery, had electrodes implanted into their brains. The scientists were able to monitor the activities of the brain cells with it. The patients were asked to categorize various images of faces, animals, and plants – as fast as possible- throughout the entire night. 

The scientists found out that as the night progressed, and the patients became tired, the patients found it hard to carry this task as fast as they did when they were still agile.


During the deep hours of sleep, short brain waves are seen to race across your brain. These brain waves are responsible for the transfer of information from the short-term memory reservoir to its long-term counterpart. You would deter your brain from this by missing sleep

Unfortunately, mere willingness to have a good night rest isn’t sufficient. Factors such as a bed mattress and a tempered circadian rhythm could have a negative impact on your sleep life. Luckily for me, since I bought a Lull mattress, the effect of sleeping on a bad mattress has been ruled out. However, you might want to check out a review of Lull mattress before taking a trip to the store.

How does a Sleepless Night Affect Your Peripheral Nervous System?

Sad enough, as much as your brain is affected by an episode of a sleepless night; your nerves aren’t left out. 

Slow Signal Receipt

Unlike the endocrine system, the nervous system, including the nerves- communicate through sending electrical impulses. This is done in a split second. Unfortunately, lack of sleep could elongate the time between which the sense organs send the impulse the receptor organ performs the action.

On the whole, you would feel sluggishness in performing simple tasks.


Let me explain what this means: you would occasionally encounter minor sleep episodes. The bad thing about this is- you won’t know you are asleep.

Yeah…wow! Imagine what this could result from you if you were driving on a major highway or you were at the window side of a 14-story building.

Wrapping Up

These consequences are clearly more than you could afford. So, avoid the risk and get some sleep!
