7 Things That Happen if You Don't Get Enough Sleep ...

I work an overnight shift once a month, and as a result have been researching things that happen if you don’t get enough sleep, on a frequent basis. I understand that it’s not good to have a sleep deficit during the week and then sleep 12 hours at the weekend to compensate either, so there has to be a balance. It's also all about quality too instead of quantity; everyone's experienced those awful nights tossing and turning, haven't they? Sleep is definitely a function of the body that helps us feel better and scientists are still trying to determine precisely why we need to sleep, but the general consensus seems to be related to the fact that our brain cells need to rest and restore themselves so that our bodies can function at their prime. Anyway, here are some horrible things that happen if you don’t get enough sleep.

Lowered Immunity

One of the things that happen if you don't get enough sleep is your body starts to get weaker and break down. I don’t know about you, but I start to feel ill if I don’t rest sufficiently each night. I wish I could survive on 5 hours a sleep, but research proves that those who get less than 7 hours of shut-eye a night (for two consecutive weeks), are more at risk of getting ill, than those who sleep a full 8 hours each night. Even if it’s one night of sleeplessness per month (which it is in my case), it can still impede your body’s ability to fight against natural air-borne micro-organisms.


Physical Symptoms

Somehow I always feel colder, as if my body temperature drops and I need to go to the bathroom more when I haven’t slept. I gather it’s a fact that your body temperature drops (by half a degree C), when you’re sleep deprived. This is a result of stress responses and reduced brain activity in the hypothalamus, the regulatory center that impacts your body’s temperature. When sleep deprived, your body doesn’t slow down its normal urine production; instead your kidneys go into overdrive when you’re awake. Urine production is usually one of those bodily functions that takes care of itself (your body slows down its urine production when you sleep).


Difficulty Remembering Things

How often do we stay up as students the night before an essay is due or cram before an exam? Thing is, sleep deprivation impairs our ability to remember words and tasks we may have been shown the day before (even a repetitive task). Short-term memory recollection is crucial when we’re studying or learning and this basic attribute of our brains can often be hampered when we don’t sleep sufficiently.


Increase on the Scales

This is definitely something women don’t want to have happen, but it’s often the case that those that sleep less hours each night than they should, tend to gain more weight. This is because there’s a chance for an increased appetite (due to hormone imbalances), and it seems harder to control our ability to discipline ourselves when it comes to satisfying sugary cravings.


Drowsiness behind the Wheel

Not only is our vision affected by a lack of sleep, but our response time, ability to react and make good judgments is equally impaired. If you feel sleepy or overly drowsy, you probably shouldn’t get behind the wheel of your car (motorbike, Vespa or other motorized piece of equipment)! It’s a fact that pilots, truck drivers, medical residents and professions that require staying awake for extended periods of time, “show an increased risk of crashes or near-misses, due to sleep deprivation (Seminars in Neurology, 2009)."


Increased Chance of Diseases

One of the worst things (in my opinion) is the enhanced ability of getting diabetes. Type 2 diabetes is on the rise in the western world and it could be a result of western societies sleeping less and less. If you stay awake when your body wants to sleep, your circadian rhythms get disrupted, your metabolism slows down, increasing your risk of insulin resistance (often termed ‘pre-diabetes’). Cancer is such a strange disease and there are so many types of cancer, that it’s hard to prove getting the illness is related to sleep deprivation. However, with the coincidences of disrupted circadian rhythms and reduced immunity, it’s no surprise that you could be more predisposed to getting certain cancers too.


Genetic Mishaps

I know this might sound strange, but a National Academy of Sciences article claims that your genes (cells and DNA) get disrupted when you don’t sleep sufficiently. A research study of people that slept less than 6 hours a night for one week showed 700 genes behaving erratically. The genes however that typically cycle according to your daily body rhythm weren’t erratic and those that don’t normally follow a daily rhythm started to behave erratically. Woah! Genetic mishaps lead to an inability for your body to cope against illnesses (colds, and other viruses, etc.) as well as other general stresses we put our bodies through.

Although our western societies are getting used to being sleep deprived, our body’s ability to judge, react, and certain bodily functions are still impaired. I know I always feel lots better when I’ve slept a good night’s sleep. Do you need a lot of sleep? What happens to you if you don’t sleep enough?

funny thing though ..... i also cant get too much sleep. because if i sleep too long i feel really sluggish and tired . i need about 6 hrs to feel pretty good

I work nights and sleep 4 hrs during the day. Not ideal, but a girl's gotta do, what a girl's gotta do.
