In this article, you’ll learn what causes insomnia, when it becomes dangerous, what tests are recommended, and which treatments really work.
What is insomnia, and how does it manifest?
Insomnia is defined as difficulty falling asleep, staying asleep, or getting restful sleep, despite conditions conducive to rest. It can be classified into two main categories:
Acute (short-term) insomnia, usually triggered by stress or emotional events.
Chronic insomnia, which persists for at least 3 nights a week for a minimum of 3 months.

- Difficulty falling asleep
- Frequent nighttime awakenings
- Waking Up Very Early in the Morning
- Feeling tired after sleeping
- Decreased ability to concentrate
- Irritability and Anxiety
Types of Insomnia
Insomnia can be classified into several types, depending on its duration, cause, and how it affects sleep. The most common forms are:
- Acute insomnia —occurs in the short term, usually during periods of stress, anxiety, or major life changes, and can last from a few days to a few weeks.
- Chronic insomnia —which persists for at least 3 nights a week for a minimum of 3 months—requires medical evaluation, as it may be associated with neurological or mental health conditions or other chronic diseases.
- Initial insomnia —the person has difficulty falling asleep, even when tired.
- Sleep maintenance insomnia —characterized by frequent awakenings during the night and difficulty falling back asleep.
- Early-morning insomnia – the patient wakes up much too early in the morning and is unable to fall back asleep.
- Secondary insomnia —occurs as a symptom of another condition, such as anxiety, depression, sleep apnea, chronic pain, or certain neurological disorders.
In practice, many people may experience a combination of several types of insomnia, which is why identifying the exact cause is essential for determining an effective treatment.
Is insomnia dangerous?
The short answer is: yes, insomnia can be dangerous, especially when it is persistent and left untreated. Lack of sleep affects the body’s normal functioning and can contribute to the development of serious health conditions. According to international studies, insomnia is one of the most common sleep disorders, affecting approximately 30% of adults worldwide, with between 10% and 15% suffering from chronic insomnia. Research also shows that sleep disorders are associated with decreased concentration, reduced cognitive performance, and an increased risk of accidents caused by fatigue.
Effects on physical health:
- Increased risk of cardiovascular disease (high blood pressure, heart attack, stroke)
- Hormonal imbalances (including elevated cortisol levels)
- Weakening of the immune system
- Increased risk of obesity and type 2 diabetes
Effects on mental health:
- Anxiety and Depression
- Decline in cognitive performance
- Memory Disorders
- Increased Risk of Burnout
In the long term, chronic insomnia can significantly reduce quality of life and exacerbate other existing conditions.
What are the most common causes of insomnia ?
Insomnia is a multifactorial condition, and identifying its cause is essential for effective treatment.
Common causes include:
- Stress and Anxiety
- Depression
- Neurological Disorders
- Chronic medical conditions (chronic pain, cardiovascular disease, endocrine disorders)
- Consumption of caffeine, alcohol, or nicotine
- Excessive use of electronic devices before bedtime

In some cases, insomnia may be associated with other sleep disorders, such as obstructive sleep apnea or restless legs syndrome.

Frequently Asked Questions About Insomnia:
- How many hours should I sleep each night?
Most adults need about 7–9 hours of sleep per night for their bodies to function optimally. Sleep needs can vary depending on age, lifestyle, and overall health. More important than the exact number of hours is the quality of sleep and how rested you feel upon waking.
- Which doctor treats insomnia?
Insomnia can be evaluated and treated by various specialists, depending on the cause of the symptoms. A neurologist, psychiatrist, or sleep medicine specialist can recommend the necessary tests and a personalized treatment plan. In some cases, a psychological evaluation may also be necessary, especially if insomnia is associated with anxiety or depression.
- Can anxiety cause insomnia?
Yes, anxiety is one of the most common causes of insomnia. Constant stress, excessive worrying, and mental tension can make it difficult to fall asleep or stay asleep throughout the night. Often, insomnia and anxiety can feed into each other, creating a vicious cycle that affects quality of life and overall health.
- What tests are performed for sleep disorders?
Depending on your symptoms and medical history, your doctor may recommend several tests to identify the cause of your sleep disorders. Among the most commonly used are polysomnography (a sleep study), a neurological evaluation, blood tests, and, in certain cases, imaging tests such as a brain MRI. These tests help diagnose associated conditions, such as sleep apnea, neurological disorders, or hormonal imbalances.
- Is it normal to wake up at night?
Occasional awakenings during the night can be normal and often occur during periods of stress or fatigue. However, if these become frequent, are accompanied by difficulty falling back asleep, or affect your energy levels during the day, they may indicate a sleep disorder. In such situations, a medical evaluation is recommended to identify the cause and determine an appropriate treatment.
