Sleep deprivation

Sleep deprivation: Why is it dangerous?

It’s not only your body that can’t function when you get enough sleep. Your brain is working overtime too.

If you think about what happens to our thinking and decision-making abilities when we haven’t slept well for several days. It becomes clear how critical sleep is to daily life. For example, we know from recent studies on airline pilots and physicians that those awake for 24 hours or more make many errors in judgment, and accident rates increase significantly. Aeroplane crashes attributed to human error rose by a third in the 1990s, and many crashes were attributed to fatigue.

How does sleep deprivation affect our ability to make sound judgments and decisions?

Chicago Tribune writer Margery Duda described her frustration with a lack of decision-making ability in an article about driving when she was overtired: “I developed such a case of mental mush that I couldn’t even figure out how my car’s cruise control worked or where my turn signals were.” 

As we all know, if we feel confused and discombobulated, it is much more challenging to think clearly. The same idea applies here. When we don’t get enough sleep, we aren’t operating at 100 per cent, and making better judgments and decisions becomes challenging. 

Sleep deprivation symptoms:

  • Lack of concentration and focus.
  • exhausted, not refreshed when waking up in the morning.
  • Lightheaded and dizzy after meals or while standing up (Orthostatic hypotension).
  • Decreased libido.
  • Depression-like symptoms such as irritability, sadness, depressed mood, etc.
  • Increased risk for heart disease and diabetes due to increased cortisol and glucose levels in the bloodstream.

What is sleep deprivation

How does sleep deprivation affect the body

It decreases concentration and focus, causes drowsiness, decreases libido(sex drive), depression-like symptoms such as irritability, sadness, etc. Increases risk for heart disease and diabetes from increased cortisol and glucose in the bloodstream.

What is a disorder associated with sleep deprivation

 A condition associated with lack of sleep is narcolepsy.

Summary: Sleep deprivation has various effects on the human body, including decreased concentration and focus, lightheadedness, dizziness after meals, or standing up quickly. Sleep deprivation also affects one's mental health as it can cause depression-like symptoms such as irritability, sadness, etc. Sleep deprivation can also cause other disorders such as narcolepsy. In addition, it may increase one's risk for heart disease and diabetes due to increased cortisol and glucose levels in the bloodstream.

Seep-deprived: 

Having a lack of sleep or not receiving enough rest.

Types of sleep deprivation:

Natural vs. experimental: Natural- loss of an entire night’s sleep from a standard 8 hour period. The practical – shortened period spent asleep by taking naps during the day coming off at night before bed.

Effectiveness of sleep deprivation treatment: Does not work well as people tend to fall asleep during activities, putting them at risk for accidents or injuries from tripping over things and stumbling etc. Further worsening effects of depression-like, etc. symptoms; the risk of heart disease and diabetes is still there, along with other known side effects such as irritability, sadness, etc. which causes the person not to want to get better.

Sleep deprivation doesn’t help improve someone’s sleep problems/disorders. Instead, it makes things worse because they might fall asleep during activities putting them at risk for injuries or tripping over things, further worsening depression-like symptoms while increasing their risk for heart disease and diabetes due to increased cortisol and glucose in the bloodstream.

Effects of stress on decision making: Individuals experiencing high levels of stress may have difficulty responding appropriately in social situations due to impaired self-regulation or self-control. Studies show that people under high levels of stress can not correctly process information, increasing the amount of time it takes to make decisions.

Decision-making under sleep deprivation: when we lack sleep, our bodies cannot regulate (control) mood with cognitive (thinking) control. Leading us to experience negative emotional outbursts or feelings. Our self-regulating ability is reduced because of the facilitated communication between the amygdala and the prefrontal cortex. Reduced communication between these two areas means that there’s a decrease in our abilities to reappraise situations positively or look at them differently than we would if we were well-rested. In addition, the communication between these areas can weaken due to environmental stressors such as relationship problems or financial difficulties, which ultimately weakens your decision-making skills.

Lack of sleep effects: Sleep deprivation can cause drowsiness, decreasing libido(sex drive), irritability, depression-like symptoms such as sadness, etc., increasing risk for heart disease and diabetes from increased cortisol and glucose in the bloodstream.

Narcolepsy disorder: Narcolepsy is a chronic sleep disorder that involves the brain’s inability to regulate sleep-wake cycles normally. It causes excessive daytime sleepiness along with a series of other symptoms. People with narcolepsy fall asleep at inappropriate times without warning. Some common narcolepsy symptoms include falling asleep while engaged in social conversations, watching TV, or even driving long distances because people are sleepy all day.

Sleep deprivation is when one does not receive enough rest or sleep.

Types of Sleep deprivation: Medication-induced, natural, experimental Natural – Loss of a whole night’s sleep in a standard 8-hour period. Practical – Cut down on the amount of time you spend sleeping by napping during the day and then waking up before bed. Medication-induced – being unable to fall or stay asleep for more than 4 hours after taking sleeping pills or medicine to help you have a night of uninterrupted sleep for 7 hours.

Effectiveness of sleep deprivation treatment:

Does not work well as it makes the person feel worse because they might fall asleep during activities putting them at risk for injuries or tripping over things, further worsening depression-like symptoms while also increasing their risk for heart disease and diabetes due to increased cortisol and glucose in the bloodstream.

Signs of sleep deprivation: 

Excessive daytime sleepiness, falling asleep during the day without warning, unable to stay awake when in conversation

Sleep-wake cycle problems (inability to fall or stay asleep), frequent napping, nightmares/bad dreams.

Symptoms of severe sleep deprivation:

Hallucinations, memory loss, fatigue. Inability to concentrate. Mood swings, irritability. Slowed reaction time. Slowed breathing can lead to an increased risk of heart attack and stroke due to a lack of oxygen sent throughout the body. It can cause you to lose focus on what you are doing because your attention span is shortened, making it difficult for you to keep track of conversations and activities occurring around you, which worsens depression-like symptoms. 
If you are sleep-deprived, your risk of developing type 2 diabetes increases because of the long-term glucose levels in your bloodstream. This increase is due to increased cortisol production, which causes resistance to insulin and, therefore, an increase in blood sugar levels.

Treatment for Sleep deprivation: 

To treat extreme cases of sleep deprivation, they may recommend napping or sleeping at night, especially if it has been difficult for them to have regular hours during the day. Those who do not have normal hours would be hospitalized. Until their sleep pattern normalizes or is regulated by doctors who decide how long patients must be hospitalized, depending on how severe their case is. Doctors will also provide patients with light therapy where they expose them to artificial lights to mimic the natural sunlight to regulate their sleep patterns.

Symptoms of lack of sleep:

Unintentional weight gain, reduced motor skills, reduced problem-solving skills.

Treatment for lack of sleep

Sleep experts suggest that you get up simultaneously every day and aim for 8 hours per night. They also recommend avoiding naps during the day or taking them to prevent them from lasting longer than 30 minutes. If you are having trouble sleeping at night, they advise that you try to go to bed earlier rather than later to ensure a better night’s rest. However, they do not recommend going to bed right before midnight because it can throw off your circadian rhythm when our bodies are supposed to be preparing for sleep around 11 pm-1 am.
