11 Life-Threatening Consequences of Sleep Deprivation You Must Know

leeping little, for many people, is almost like death. This is because, as a result of a bad night’s sleep, most people are unable to perform well during the day, are inattentive, irritated, hungry, have a sore body, and maintaining concentration is becoming a task more complicated than usual.

But, as you will see today, this classic, more immediate symptoms of lack of sleep are not the only ones you have to worry about. In fact, getting little sleep over time can be a path of no return, which can have numerous bad consequences for everyone’s physical and mental health.

Interestingly, recent studies from the National Institute of Health revealed that over 50 to 70 million U.S. adults have sleep disorders.

So, in this blog, we will share 11 severe health complications sleeplessness can cause. As you will see, heart disease, obesity, diabetes, and a host of other serious problems can come up shortly if you do not adjust your sleeping hours to feel restored and rested in the morning.

Sleep Deprivation Side Effects on Mind and Body

So, get ready to sleep at least 7 hours the next night after you’re done reading this. And, if you lose a good night’s sleep for some reason, try to make the most of that loss the following night to maintain your body and health day.

1. The brain works harder

Brains that are sleep deprived are not efficient; they have to work harder.

This has been shown in brain imaging studies that show that the sleepless brain must desperately pump more energy into the prefrontal cortex, trying to overcome the effects of sleep deprivation.

If your problem is due to the fact that you cannot sleep easily, it may be useful to understand if you have to change your habits before going to bed.

2. Low immunity

When you sleep, your body works in the production of antibodies, which are responsible for defending our bodies against infections, viruses, bacteria, and other villains that can compromise our health. But if you don’t get enough sleep, your body doesn’t make enough antibodies for your protection, and your immunity goes down considerably. In addition, if you become ill, you will not have enough energy to recover, and you will be sick longer.

3. Obesity

Scientific studies have pointed to a close link between sleep deprivation and hormonal changes that influence hunger and food choices. Therefore, not getting enough sleep can lead to obesity, either because of the anxiety of staying awake at the wrong times, which provides the impetus for fatter and sweeter foods; due to the body’s own lack of control.

According to studies developed, sleeping 6 hours or less a night increases the production of a hormone called ghrelin, which causes hunger. This sleep time also considerably decreases the production of leptin, another hormone responsible for the feeling of satiety.

This is basically why people tend to eat more and less healthy foods when they do not sleep well. And if this becomes a habit, obesity is not far off.

Now, if your intention is to lose weight and get in shape, in addition to getting the right sleep, you also need to learn to speed up your metabolism.

4. Mania

If a person suffers from sleep deprivation on a regular basis, they begin to experience real delusions. Symptoms include psychosis, paranoia, extremely high vital energy levels, hallucinations, aggression, and much more.

Important links have been found between insomnia and mental illness. Unfortunately, the mental illness itself can, in turn, cause insomnia. Those who find it difficult to sleep, risk triggering a vicious circle!

5. Long-term memory loss

Sleep plays an important role in consolidating memory.

While we sleep, our brain tidies up, integrates, and makes sense of the things that happened to us.

Not only that, but our learning is consolidated while we sleep.

Sleeping poorly interrupts these processes, weakens long-term memory, and it is more difficult to learn new skills.

6. Respiratory System

The relationship between sleep and the respiratory system occurs both ways. A nocturnal breathing disorder called obstructive sleep apnea (OSA) can disrupt sleep and decrease quality.

As you wake up at night, this can cause sleep deprivation, which makes you more vulnerable to respiratory infections such as the common cold and the flu. Sleep deprivation can also worsen existing respiratory diseases such as chronic lung disease.

7. Digestive System

Sleep affects the levels of two hormones, leptin, and ghrelin, which control feelings of hunger and fullness.

Leptin tells the brain that you have eaten enough. Without enough sleep, the brain reduces leptin and increases ghrelin, which is an appetite stimulant. The flow of these hormones could explain the evening snacks or why someone might eat later in the evening.

Lack of sleep can also make you feel too tired to exercise. Over time, reduced physical activity can lead to weight gain because you are not burning enough calories and building muscle mass.

In addition, not getting enough sleep also causes the body to release higher insulin levels after eating. Insulin controls the amount of sugar in the blood. Higher insulin levels promote fat storage and increase the risk of type 2 diabetes.

8. Stroke

According to recent studies, can also be a consequence of sleep deprivation. Scientists point out that people who sleep less than 6 hours a night are at four times the risk of stroke. Tense, no?

9. Cancer

Parex is an exaggeration, but scientific studies by leading universities already link some to people not getting enough sleep.

One of the cancers that are most likely to be caused by sleep deprivation is colorectal (right where you are thinking), as polyps tend to be more frequent in people who complain of poor sleep and constant tiredness. Because, if you do not know, the lack of restorative sleep also hinders bowel function, which can cause numerous problems in the long run.

10. The death of brain cells

Many different types of studies have shown that continuing to sleep poorly damages brain cells a lot.

A recent study found that in mice, as many as 25% of brain cells die from prolonged lack of sleep. Other studies have found that there is a loss of white matter integrity in the brain, possibly due to lack of sleep.

Sleeping little is not good psychologically and is not good physiologically.

11. Reduced Longevity

After all these negative factors that can appear if a person sleeps little, we need not say that sleeping poorly can shorten their lifetime too. But, this was also a confirmed factor in studies related to the subject.

According to researchers, on average, people who sleep less than 6 hours a night usually die before those who sleep more (at least 7 hours), regardless of the cause. Because, as you have seen throughout the story, in addition to lowering immunity, not getting enough sleep leaves you exposed to a host of deadly evils.
