Body disorders come in handy with lack of sleep. There are minimum number of hours of sleep the body can be Ok with and there are hours of no sleep that the body might break down

Here 7 body disorders lack of sleep can do to your body when you do not sleep well at night

1. It Weakens Your Immune System

According to a study in the “Cancer Research” journal from researchers at the University of Chicago and University of Louisville, “Poor-quality sleep marked by frequent awakenings can speed cancer growth, increase tumor aggressiveness and dampen the immune system’s ability to control or eradicate early cancers.”

​A lack of sleep has often been linked to a poor immune system, so it’s no wonder that so many college students, and just night owls in general, get sick so frequently.

2. Lead to bad decisions.

We all know that slaphappy feeling that comes when lack of sleep triggers a rush of natural painkillers—but that’s not strictly a good thing. Feel-good hormones like dopamine interfere with the brain’s ability to plan logically, sometimes resulting in unpredictable behavior and an increased willingness to take risks.

3. Make you ugly.

Well, OK, maybe not ugly per se, but there’s a reason they call it “beauty rest.” Sleep deprivation can result in shakiness, sallow skin tone, dark under-eye circles, and an overall run-down, disheveled look. Sleep deprivation over time is also associated with increased body mass.

4. Do more academic harm than good.

Even though it can sometimes feel like your only option, all-night cramming is a bad study strategy. In essence, when you stay up, the restorative, consolidating effects of sleep are lost, and the information doesn’t “click.” You’re actually much better off with a normal study session, a good night’s sleep, and a light breakfast on exam day.

5. Have terrible long-term effects.

According to the National Institute of Health, habitual sleeplessness can result in decreased learning capacity—which is pretty crucial for a little thing we call success. So even if all-night cramming works in a pinch for that elective course, it’s not a good idea to rely on it for building the skills that you’ll actually need to use someday.

6. Harm to your body.

Beyond the usual grogginess and irritability that comes with fatigue, habitual sleeplessness can intensify a host of emotional problems that includes anxiety, depression, and bipolar disorder.

7. It Creates Bad Eating Habits

Sadly it’s possible for late-night sleepers to eat 248 more calories a day than those who get to bed at a decent hour, and all of that can lead to about two pounds per month.​ Although co-lead author Kathryn Reid admitted that the study and research couldn’t confirm whether or not people choose poor food options at night because they’re night owls or simply because those specific, unhealthy options are the only ones available, the correlation between weight gain and the time participants went to sleep was prevalent.
