How Does The LACK OF SLEEP Affect Your Health?

Spread the love

Do you know how does lack of sleep affects your health? Everyone knows after doing activities for hours, our body and brain need to have some adequate rest. Especially with the work and social pressures, our brain becomes tired, so it needs to be rested.

Sleep has a role in blood circulation, repairing body cells, and helping the production of enzymes and hormones. When not getting enough sleep, various diseases will come to the body, ranging from trivial skin problems such as acne to serious health problems, namely high blood pressure, heart disease, stroke, diabetes, and so on.

A body that lack of rest will show some symptoms. Let’s find out more from the review below.

How Does The Lack of Sleep Affect Your Health? – From Dementia to Depression

How does the lack of sleep affect your health?

For some people, insomnia is a fairly common thing. Stress, daily activities, life acceleration make it difficult for you to sleep at night. Though most of us know that staying awake for a long time can be bad for health.


The effects of lack of sleep on the brain

Effects of lack of sleep on the brain

The following study discusses the effects of long-term sleep deprivation on your brain.

Our immune system, respiratory system, and energy levels are regenerated by sleep. Sleep also allows the brain to process the information it has obtained throughout the day, besides regulating our blood pressure and heart rate. During sleep, the body also removes toxins from the neurological activity that we experience during the day. When you don’t have enough time to rest, the body actually turns poisons into a kind of fuel reserve.

Lack of sleep burns brain fuel

In the short term, by eliminating these poisons, our brain will be healthier because all the energy is used for the process. However, in the long run, in cases with people suffering from sleep apnea or chronic insomnia, using all of their brain cavities can affect its function and contribute to this vital organ’s degeneration.

A study using mice

A team of neurologists, led by Michele Bellesi of the Polytechnic University of Marche in Italy, conducted research using mice which they divided into several different groups.

The first group can sleep as much as they want during the day. The second is required to be awake and sleep less than 8 hours a day, and the third group must stay awake for 5 consecutive days so that scientists can observe changes in their brains and see what happens to it.

Clean the cell

Astrocytes are responsible for the brain’s cleansing function and are found in mice as well. By observing the activity of these cells, they can get results.

At the end of the experiment, the mice brain that slept long enough had an astrocyte level of 6%, the second group had an astrocyte activity level of 8%, and the third one after 5 days had astrocyte activity of 13.5%. This means the less we sleep, the more our brain cells will do a thorough “cleaning.”

The brain can ‘eat’ itself

In mice, this process consists of consuming synapses in their brain and showing that the same effect can occur in humans. By not sleeping for several nights in a row, we risk this function to overflow, make us vulnerable to degenerative diseases such as Alzheimer’s, or contribute to dementia in the long term.

Other health problems caused by lack of sleep

Passing by school children or office workers who seemed to have a lack of sleep is no longer a new phenomenon on the streets.

When you have a lack of sleep, it’s true that you will feel tired, irritable or angry, and less productive. However, the long-term effects of sleep deprivation will not only affect your physical health. By not having enough time to sleep, we risk ourselves to get various health problems. Starting from gaining weight to lowering your immune system and making you sick quickly. What’s more, your brain function also drops sharply so that it can trigger a variety of health problems:

1. The brain becomes slow

How does the lack of sleep affect your health?Researchers have found that lack of sleep can cause alertness and decreased brain concentration. No wonder if after many hours (or even days) not sleeping well, you become confused yourself, forget easily, and have difficulty thinking clearly.

In the medical world, the condition of thinking disorders due to brain fatigue is often referred to as brain fog. But you might be more familiar with the term slow. A slow brain makes it difficult for you to make important decisions.

Although seemingly trivial, this brain fog should not be underestimated. Brain fog can be an early symptom of dementia.

The reaction time for something will also be slower. This is actually dangerous if you are doing activities like driving and operating heavy equipment.

This has the potential to harm yourself and others. A survey shows, ⅓ car drivers fall asleep while driving due to lack of sleep at night!

Next thing is, the ability to solve problems will be declining. With enough sleep, you give the brain time to always improve the ability to think creatively and think of new ideas.

Can you imagine the impact if you work in an area that requires optimal thinking, but you always have less time to sleep at night?


2. Memory deterioration

The effects of sleep deprivation to the brainWhen you are sleepy, you tend to forget easily. Aside from the concentration and focus of the brain which worsens, due to lack of sleep, memory also slowly deteriorates.

Because during your sleep, the nerves in the brain that store memories are strengthened. An expert from the University of Maryland School of Medicine in the United States, Dr. Avelino Verceles, said, “During sleep, the brain records the things we have learned and experienced all day long into short-term memories.” (That’s why you also can’t go to sleep in a state of anger).


3. Difficult to accept new information

Effects of lack of sleepSleep deprivation can affect your ability to understand new information in two ways. First, you will become unfocused, making it difficult to receive new information. That way, you can’t study efficiently.

Secondly, as mentioned above, the lack of sleep impacts the ability to remember. Weak memory will make it difficult for you to store new information that you learn into memory.

Sleeping for a while after learning new information has been shown to increase the ability to remember and use that information later on.


4. Triggering mental illness

Lack of sleep or sleep deprivation can trigger mental health problems like depressionSleep deprivation is indeed not a direct cause of psychiatric disorders. However, various studies have found great potential for the emergence of several mental illnesses, such as depression, ADHD, anxiety disorders, and bipolar disorder as a result of lack of sleep.

A study in Michigan, USA, looked at a thousand people aged 21 to 30 years. As a result, those who suffered from insomnia in the first interview had a four times greater risk of suffering from depression when interviewed again three years later. Another study found that sleep disturbance problems occurred before the onset of depression. In addition, depression sufferers who experience insomnia will be more difficult to cure compared to those who do not experience insomnia.

In one study, experts found that insomnia and other sleep disorders might worsen episodes of mania (manic) or depression (depressive) in patients with bipolar disorder. Sleep deprivation itself is believed to trigger episodes of mania, which is a phase of emotional outbursts or uncontrolled behavior.

As a result of a lack of sleep can also trigger anxiety disorders. One study reported that about 27 percent of patients with anxiety disorders begin with insomnia which makes a person difficult to sleep.

5. Always feel hungry

Brain specialist and sleep medicine Dr. Chris Winter mentions that one sign of sleep deprivation is constantly feeling hungry. “If the brain does not get enough energy by sleeping, the brain will replace the lack of energy from food,” he explained.

Lack of sleep and rest will increase the production of ghrelin, the hunger hormone in the stomach. Winter explained excess ghrelin will cause the body to ask for fatty and sweet foods. He also mentioned that lack of sleep will affect leptin, which is the hormone full.

“When you don’t get enough sleep, you tend to eat more fatty and sweet foods because the signal that your body is full is disturbed,” he said.

6. Weight gain

As explained earlier, the lack of sleep causes hunger and eventually leads the body to eat sweet and fatty foods. This will result in weight gain.

“When you are tired, you will not be aware of what foods enter the body,” Winter explained. “You look for and eat any food that keeps the body awake”.

According to Winter, insufficient sleep also affects metabolism directly. “The body’s metabolic process will decrease,” he said.

In addition, according to a study published in the Journal Annals of Internal Medicine in 2012, sleeping for 4.5 hours a day in four consecutive days can reduce the body’s fat cell response to the hormone insulin by 30 percent. Finally, fat that is supposed to be converted by insulin into the body’s energy is actually buried in the body.


7. More impulsive

Are you easily irritated if you’re hungry? I know I am. This turned out to be true because the body tends to be more impulsive in a state of fatigue, especially coupled with hunger. Health expert Dr.Gail Saltz said that the body in a state of fatigue tends to do things without thinking. “The ability to choose food and to refrain becomes more difficult,” she explained.

Not only related to food but in a state of fatigue, you also tend to do things spontaneously, such as angry with others.

“This is because the brain does not have the ability to forbid the body,” explains Kelly Baron, professor of neurology at the Northwestern University of Chicago in the United States.

Sleep deprivation treatments

Every night millions of people struggle to sleep, so we call it insomnia.

According to Medical News Today, every year in the United States about 40% of adults experience insomnia.

Sleep deprivation is also considered a “public health problem” by the Centers for Disease Control and Prevention (CDC).

Some of these scientifically proven natural therapies can overcome insomnia and restore sleep.

1. Aromatherapy

Aromatherapy for sleep deprivation

Lavender scents are known to induce a sense of calm and relaxation, and not surprisingly, sleep.

Studies show that massage with essential oils especially lavender can result in better sleep quality.

In addition, this oil can improve the mood, maintain good concentration, and reduce anxiety.

Research has also shown that aromatherapy with lavender slows the activity of the nervous system.

This helps to improve the quality of sleep and positive mood in those with sleep disorders.

2. Light Therapy

Light therapy for sleep deprivation

Turning on the light before bed helps Moms fall asleep and stay asleep.

Low lighting at night will help trigger the production of melatonin, a sleep-inducing hormone.

A 2014 study published in the Journal of Clinical Sleep Medicine conducted research on office workers.

Office workers who are exposed to natural light often sleep about 46 minutes longer per night than their colleagues who use lights.

Findings show that the work environment can also play a role in nighttime sleep habits.

Getting adequate daylight exposure at work can help employees’ health and well-being.


3. Acupuncture

Acupuncture to help with sleep deprivation

Acupuncture may increase the secretion of human melatonin production.

A study in the Journal of Neuropsychiatry and Clinical Neurosciences found facts about acupuncture.

Studies suggest that after five weeks of acupuncture treatment, there will be an increase in melatonin production.

This melatonin improves one’s sleep and sleeps quality.

Certain acupuncture procedures have a success rate of almost 90% for insomnia treatment.


4. Herbal Supplements

Melatonin is the most popular supplement for sleep, according to the American Academy of Sleep Medicine.

This can help insomnia patients overcome temporary sleep disorders.

Melatonin can help a person to sleep faster, lengthen sleep, and improve sleep quality.

In addition, they found that the longer the patient was on this supplement, and the higher the dose, the greater the effect on total bedtime.

Mayo Clinic recommends consumption of this supplement 0.5-5 milligrams before sleeping daily for one to three months.

  3. I am the type of person that gets to studying and before I know it, it is three in the morning and I have to be up for work in three hours. I do it to myself all of the time.
    I used to fool myself and believe that I could function on three or four hours of sleep each night. I can normally handle it for about two weeks, but then it catches up with me.
    I become irritable, short minded, and I cannot eat enough: some of the things you mentioned in your post.
    It took me a long time to realize what I was doing to myself with my compulsive, nerd-like quality of learning.
