Woefully tired every time your alarms go off early in the morning? If so, you aren’t alone – not by a long shot, actually, because chronic lack of sleep seems to be a distinguishing feature of modern society: the average American adult gets less than 7 hours of sleep each night.
Woefully tired every time your alarms go off early in the morning? If so, you aren’t alone.
But is sleep loss really that big of a deal? Other than the near-infinite sequence of yawns it might induce during early-morning meetings – not to mention puffy, tired-looking eyes – are there any serious consequences of not getting ample sleep?
As it turns out, sleep loss comes with quite a few possible consequences. In the past decades, as chronic sleep deprivation has become a rather rampant phenomenon, scientists have meticulously researched the effects of sleep loss on one’s health and well-being. And the effects are – more often than not – destructive to one’s well-being and far from beneficial.
Consider, for instance, these 10 consequences of lack of sleep.
Sleep is vital for the formation of memories in your mind.
Sleep is vital for the formation of memories in your mind. It stands to reason, then, that a lack of sleep can impair your working memory. This is supported by a wealth of research; for example, sleep loss reduces your ability to recall specific objects.
Symptoms of depression are associated with sleep loss.
Perhaps you’ve been feeling pretty gloomy lately – with a headspace full of depressed thoughts. That could be because you’re not getting enough sleep, as symptoms of depression are associated with sleep loss.
Lack of sleep can change how the brain anticipates impending events – and can thus directly cause anxiety.

Sleep loss is linked to a significantly higher rate of suicidal ideation.
Getting sufficient sleep appears to be so important for one’s well-being that sleep loss is linked to a significantly higher rate of suicidal ideation and attempts. (Note that if you or someone you know is suicidal, it’s recommended that you call the National Suicide Prevention Lifeline at 1-800-273-8255.)
Lack of sleep can increase the risk of various diseases like type 2 diabetes.
Both quantity and quality of sleep affect your body’s hormone levels – including the hormones involved in glucose metabolism – so it’s little wonder that lack of sleep can increase the risk of various diseases like type 2 diabetes.
Sleep loss can cause you to eat more and thus gain weight.
Your risk of obesity could rise if you’re constantly low on sleep. That’s because lack of sleep can elevate your levels of the “hunger hormone” known as ghrelin – which (as its nickname suggests) makes you feel hungrier. Over the long-term, then, sleep loss can cause you to eat more and thus gain weight.
Driving-while-sleepy can be just as dangerous as driving-while-intoxicated.
Driving-while-sleepy can be just as dangerous as driving-while-intoxicated. Every year, tens of thousands of car accidents occur – many of them fatal – because of sleep-deprived driving. So next time you’re behind the wheel on a long, seemingly never-ending road trip and you’re starting to feel drowsy, stop putting the pedal to the metal. Instead, find a safe spot to park your vehicle and catch some rest.

Have a big presentation coming up? Considering getting enough sleep beforehand, because sleep loss can lead to monotonous, unclear speech.

If your blood pressure has been climbing, it may be time to get more sleep.
If your blood pressure has been climbing, it may be time to have a look at your sleep schedule: lack of sleep is known to elevate blood pressure – a condition known as hypertension. Hypertension, in turn, is a major risk factor for a number of cardiovascular diseases.
As these possible consequences of sleep deprivation clearly indicate, sleep is absolutely critical to your long-term health and wellness.
