What is insomnia? Causes, symptoms, and treatment.

What is insomnia?

Have you ever found yourself lying awake in the dark, staring at the ceiling, tossing and turning for hours without being able to fall asleep? Or perhaps you wake up in the middle of the night and can't get back to sleep, resulting in feeling tired and unrested the next morning, as if your brain hasn't had enough rest? If you're experiencing these situations, you might not just be "staying up late," but could be suffering from a condition called... “"Insomnia"”

Sleep isn't just about switching off your body; it's a golden period when the brain and various systems repair themselves. This article will take you on a deep dive to understand just that. What is insomnia? What are the causes, and more importantly, How to cure insomnia? To help you regain quality sleep and wake up feeling refreshed and ready for the new day.

What is insomnia?

Insomnia is a sleep disorder characterized by difficulty falling asleep, even when given sufficient time and opportunity. Symptoms include difficulty falling asleep, taking a long time to drift off, frequent awakenings during the night, and waking up too early and being unable to fall back asleep.

A common misconception is that many people think insomnia simply means "not sleeping at all." However, medically speaking, if you sleep but wake up feeling unrested, have headaches, feel dizzy, or experience excessive daytime sleepiness, that's also a sign of a sleep problem that needs addressing.

Difficulty sleeping

How many hours of sleep do we need per day to get enough rest?

A frequently asked question is, "How long should we sleep to be considered 'enough'?" In reality, the "number of hours of sleep" varies from person to person depending on their age and circadian rhythm. Medical information indicates the optimal number of hours of rest for each age group as follows:

The ideal number of hours of sleep for each age group.

To allow the body and brain to fully recover, the following timeframes should be considered:

  • Newborns (0-3 months): 14-17 hours a day
  • Toddlers (1-2 years): 11-14 hours per day
  • Children aged (3-5 years): 10-13 hours per day
  • School-aged children (6-13 years): 9-11 hours a day
  • Teenagers (14-17 years old): 8-10 hours a day
  • Adults (18-64 years): 7-9 hours a day
  • Senior citizens (65 years and older): 7-8 hours of sleep per day (though actual sleep hours may be shorter as the body naturally produces less of the substances that promote sleep).

I get enough sleep but still don't feel refreshed. What could be the reason?

If you're someone who gets the recommended 8 hours of sleep but wake up feeling unrested, tired, and heavy, this indicates "poor sleep quality." This may be due to undiagnosed sleep complications, especially... sleep apnea (Obstructive Sleep Apnea – OSA)

People with this condition snore and experience periods of sleep apnea throughout the night, leading to decreased blood oxygen levels. The brain then forces the body to awaken (micro-arousal) for deep breaths, resulting in shallow sleep and an incomplete sleep cycle. This is a major reason why even long hours of sleep are never enough, and it's a silent threat that's more dangerous than ordinary insomnia.

Symptoms of insomnia.

Insomnia symptoms What are the symptoms? This condition isn't limited to just night blindness; it also affects you during the day, which can be observed as follows:

Common symptoms found in patients with insomnia.

  • Difficulty sleeping: I lie down, but it takes more than 30 minutes to an hour to fall asleep.
  • Interrupted Sleep: I woke up several times in the middle of the night, and once I was awake, it was difficult to fall back asleep.
  • Waking up unusually early: I woke up before I was supposed to and couldn't fall back asleep.
  • I feel like I haven't slept at all. Even after going to sleep, you may feel that your sleep was of poor quality or that you didn't sleep soundly.

Warning signs that should not be ignored.

If insomnia starts affecting your daily life, here are some warning signs that you should start looking for treatment:

  • I feel drowsy and yawn constantly during the day.
  • Mood swings, easily irritated, low tolerance.
  • Shorter attention spans lead to a noticeable decrease in work or academic performance.
  • I regularly experience a dull headache in the mornings.
  • I start feeling anxious as bedtime approaches (afraid I won't be able to sleep).

Causes of insomnia.

In order to solve the problem effectively, we first need to know... Causes of insomnia. Where does it come from? This can be divided into three main factors:

Physical causes

Illness or disorders of the body's systems are significant triggering factors:

  • congenital disease: Chronic pain, acid reflux disease (GERD), asthma, or allergies that make breathing difficult.
  • Sleep apnea: Airway obstruction causes snoring and sudden awakenings during sleep.
  • The nervous system is alert: Some people have nervous systems that are more sensitive to stimuli than normal, making it difficult for them to sleep.
  • Hormonal changes: For example, during menopause or menstruation.

Psychological causes and stress.

Mental health issues are a leading cause of chronic insomnia:

  • Stress and anxiety: Work, money, or family problems can keep your mind racing even as soon as your head hits the pillow.
  • depression: People with depression often have sleep problems as well, which may include insomnia or excessive sleep.
  • Bipolar disorder: During a manic episode, the patient may feel that they don't need to sleep.

Behaviors and lifestyles that trigger insomnia.

Bad sleep hygiene habits can be the culprit behind poor sleep:

  • Using the blue screen of death: Using mobile phones, tablets, or watching TV before bed emitts blue light that inhibits melatonin production.
  • Eating habits: Drinking tea, coffee, or other caffeinated beverages in the afternoon or evening, or having a heavy meal before bed.
  • Irregular sleep patterns: Shift work or fluctuating sleep patterns (going late and waking up late)
  • Environment: The bedroom is disturbing with light, noisy, or has an unsuitable temperature.

The severity of insomnia.

The severity of this disease can be categorized based on the duration of symptoms, leading to different treatment methods.

Transient and Short-term Insomnia

  • Temporary symptoms: This usually lasts only a few days and is often caused by a change of location (to an unfamiliar place) or jet lag when traveling across time zones.
  • Short term: Symptoms lasting 2-3 days to 3 weeks are often caused by acute stress, such as exams, changing jobs, or the loss of a loved one. The symptoms usually disappear on their own as the person adjusts or the stress decreases.

Chronic insomnia

If you experience insomnia for at least three nights a week, and this persists for more than 1-3 months, it is classified as chronic. This may be due to a physical illness (such as sleep apnea) or a direct sleep disorder (primary sleep disorder). In this case, it is necessary to consult a specialist for diagnosis and treatment.

The dangers of insomnia if left untreated.

Many people choose to endure insomnia, unaware that leaving it untreated can have more serious consequences than just feeling sleepy.

How does insomnia affect the brain and mood?

Lack of sufficient sleep directly affects the prefrontal cortex, which controls decision-making and emotions, leading to impaired memory, increased risk of Alzheimer's disease, depression, and an increased risk of accidents due to drowsiness.

Impact on physical health.

A body that fails to repair itself can lead to various serious illnesses, including:

  • High blood pressure and heart disease.
  • Diabetes (due to abnormal sugar metabolism)
  • A weakened immune system means you get sick easily and recover slowly.
  • Obesity (due to malfunction of hunger-regulating hormones)

Diagnosing insomnia.

When you go to see a doctor to discuss... Insomnia The doctor will follow these diagnostic steps to determine the underlying cause:

Taking a history and assessing sleep patterns.

The doctor will begin by taking a detailed medical history, which may include questions about bedtime habits, stress levels, medication use, and whether or not you snore or experience sleep apnea, in order to rule out other psychiatric or medical conditions.

Sleep test

In cases where a patient has chronic insomnia that does not improve after more than 6 months of treatment, or if the doctor suspects co-occurring sleep apnea, the doctor may recommend the following: Sleep Test

examination Sleep Test This is the most detailed measurement of bodily functions during sleep. Devices are attached to measure brainwaves, breathing, blood oxygen levels, and body movement. The results help doctors determine whether your insomnia is due to respiratory structural issues (such as snoring that causes sleep apnea) or abnormal brainwave patterns. This leads to the selection of the most targeted treatment, such as using a positive airway pressure (CPAP) machine if sleep apnea is detected.

Treatment of insomnia.

Now we come to the crucial question: How to cure insomnia? or Insomnia Treatment What are the possible methods? Treatment approaches can be divided into two main groups.

Treatment of insomnia by a doctor or with medication.

  1. Pharmacotherapy: Your doctor may consider prescribing sleep aids or anti-anxiety medication to help balance brain chemicals. Medication should only be used under a doctor's supervision. And it should not be used continuously for more than 2-3 weeks because it may lead to addiction and drug resistance.
  2. hormoneMelatonin (Melatonin): In some cases, doctors may prescribe synthetic melatonin to help regulate the body's circadian rhythm, especially in older adults or those experiencing jet lag.
  3. Treatment for sleep apnea: If a sleep test reveals that the cause is sleep apnea, the gold standard treatment is the use of a sleep apnea machine. CPAP (Continuous Positive Airway Pressure) This helps keep the airways clear throughout the night, allowing patients to regain sound sleep and receive sufficient oxygen, ultimately resolving insomnia without the need for medication.

Treating insomnia without medication.

For those with mild symptoms or who require treatment in conjunction with medication, lifestyle modifications are the most important.

Adjusting sleep habits (Sleep Hygiene)

  • Arrange your bedroom appropriately: The bedroom should be completely dark, quiet, and comfortably cool (around 25 degrees Celsius).
  • Beds are for sleeping only: Avoid working, eating, or using your phone in bed so that your brain learns that the bed is a place for rest.
  • Avoid stimulants: Avoid coffee, tea, soda, and alcohol at least 4-6 hours before bedtime. (Alcohol may help you fall asleep easily, but it will lead to shallower sleep and more frequent awakenings.)
  • Deadline: Go to bed and wake up at the same time every day, even on weekends, to set your body clock correctly.

Techniques for improving sleep quality.

  • The 20-minute rule: If you've been in bed for 20 minutes and still can't fall asleep, don't force yourself to stay in bed. Get out and do something light, such as reading a book or listening to instrumental music. When you start to feel sleepy, go back to bed.
  • Relax before bedtime: Create a relaxation routine, such as taking a warm bath, meditating, or practicing deep breathing exercises, to reduce body tension.
  • Exercise regularly: Exercise can help you fall asleep more easily, but you should avoid strenuous exercise in the 3-4 hours before bedtime as it can make your body too alert.

Insomnia is not a minor issue to be overlooked, as it is fundamental to good health. If lifestyle changes don't improve your condition, or if people notice unusually loud snoring, consulting a specialist or undergoing a sleep test may be the key to unlocking restful sleep again.
