If you’ve ever spent a night tossing and turning, you know how you’ll feel the next day—tired, cranky, and out of sorts. But skipping the recommended 7-9 hours of shut-eye at night does more than just make you feel grumpy and grumpy.

How To Survive (and Thrive) When You’re Sleep Deprived

Read on to learn what causes sleep deprivation and how it affects certain body functions and systems.

In a nutshell, sleep deprivation is caused by a constant lack of sleep or poor quality of sleep. Sleeping less than 7 hours on a regular basis can have harmful consequences for your health that affect your entire body. This can also be caused by an underlying sleep disorder.

Your body needs sleep as well as air and food to function at its best. During sleep, the body heals itself and restores its chemical balance. Your brain creates new thought connections and helps retain memory.

Without enough sleep, the brain and body systems do not function properly. It can also dramatically reduce your quality of life.

Sleep Deprivation Stages (and How To Avoid Them)

Stimulants like caffeine are not enough to override the body’s need for deep sleep. In fact, they can make sleep deprivation worse by making it harder to fall asleep at night.

This, in turn, can lead to a cycle of insomnia at night, followed by caffeine consumption during the day to combat the fatigue of losing hours of shut-eye.

Behind the scenes, chronic lack of sleep can disrupt the body’s internal systems and cause more than just the initial signs and symptoms listed above.

The central nervous system is the body’s main information pathway. Sleep is necessary for proper functioning, but chronic insomnia can disrupt the way your body normally sends and processes information.

What Sleep Deprivation Does To Your Body

During sleep, pathways are formed between nerve cells (neurons) in the brain that help us remember new information we learn. Lack of sleep exhausts the brain, so it cannot perform its tasks well.

You may also find it harder to concentrate or learn new things. Signals sent by the body can also be delayed, reducing coordination and increasing the risk of accidents.

Lack of sleep also negatively affects your mental abilities and emotional state. You may feel more impatient or prone to mood swings. It can also compromise decision-making processes and creativity.

If the lack of sleep goes on long enough, you may have hallucinations—seeing or hearing things that aren’t really there. Lack of sleep can also trigger mania in people with bipolar disorder. Other psychological risks include:

You may also experience microsleeps during the day. In these episodes, he falls asleep for a few seconds without realizing it.

Microsleeping is out of your control and can be extremely dangerous when you’re driving. You may also be more prone to injury if you operate heavy machinery at work and have microsleep episodes.

While you sleep, your immune system produces protective, infection-fighting substances, such as antibodies and cytokines. It uses these substances to fight off foreign invaders such as bacteria and viruses.

Certain cytokines also help you sleep, so your immune system protects your body more effectively against diseases.

The Effects Of Sleep Deprivation

Lack of sleep prevents your immune system from boosting its strength. If you don’t get enough sleep, your body may not be able to fend off invaders and it may take longer to recover from an illness.

The relationship between sleep and the respiratory system goes both ways. A nighttime breathing disorder called obstructive sleep apnea (OSA) can disrupt sleep and reduce sleep quality.

As you wake up during the night, this can cause sleep deprivation, making you more vulnerable to respiratory infections like colds and flu. Lack of sleep can also aggravate existing respiratory diseases, such as chronic lung disease.

Along with eating too much and not exercising, lack of sleep is another risk factor for overweight and obesity. Sleep affects the levels of two hormones, leptin and ghrelin, which regulate feelings of hunger and satiety.

Ways Sleep Deprivation Is Wrecking Your Body

Leptin tells your brain that you have eaten enough. Without enough sleep, the brain decreases leptin levels and increases ghrelin, which stimulates appetite. The flow of these hormones may explain nighttime snacking or why someone eats too much during the night.

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

Lack of sleep also causes the body to release less insulin after a meal. Insulin helps lower blood sugar (glucose) levels.

Lack of sleep reduces the body’s glucose tolerance and is associated with insulin resistance. These disorders can lead to diabetes mellitus and obesity.

Can Lack Of Sleep Affect The Respiratory System?

Sleep affects processes that keep the heart and blood vessels healthy, including those that affect blood sugar, blood pressure, and inflammation levels. It also plays a vital role in the body’s ability to heal and repair blood vessels and the heart.

People who don’t get enough sleep are more likely to get cardiovascular disease. One analysis linked insomnia to an increased risk of heart attack and stroke.

Hormone production depends on your sleep. To produce testosterone, you need at least 3 hours of uninterrupted sleep, which is about the first R.E.M. it’s time episode. Waking up at night can affect hormone production.

This interruption can also affect the production of growth hormone, especially in children and adolescents. Among other growth functions, these hormones help the body build muscle mass and repair cells and tissues.
