What Is Insomnia?
Insomnia is trouble falling asleep, staying asleep or waking up too early and not being able to get back to sleep. It leads to daytime fatigue, irritability and reduced performance.
Short-Term vs. Chronic Insomnia
- Short-term insomnia (also known as acute insomnia) lasts a few days or weeks and is usually triggered by stress or environmental changes.
- Chronic insomnia occurs at least three times a week and lasts more than three months. It usually requires medical attention and structured treatment.
How Common Is It?
Insomnia is more common than you think. Studies show that around 10–15% of Europeans suffer from chronic insomnia, while up to 30–35% experience short-term sleep disturbances each year.
Why It Matters
Sleep is connected to almost every system in the body. Chronic insomnia increases the risk of:
- Heart disease
- Diabetes
- Workplace and driving accidents
- Mental health issues like depression and anxiety
Types of Insomnia
Insomnia isn’t one size fits all. Knowing the types of insomnia will help you identify patterns and find the right solutions.
1. Sleep-Onset Insomnia:
Trouble falling asleep at the beginning of the night. Often caused by anxiety, stress or poor sleep habits.
2. Sleep-Maintenance Insomnia
Trouble staying asleep through the night. You wake up frequently or lie awake for hours.
3. Early-Morning Awakening Insomnia
Waking up way earlier than you want to and can’t get back to sleep. This type is common in depression.
4. Comorbid or Secondary Insomnia
Occurs with other medical or psychological conditions like chronic pain, depression or sleep apnea.

A rare lifelong sleep disorder that starts in childhood and has no cause. Knowing the types of insomnia you’re dealing with is the first step to finding the right treatment.

Even with enough hours in bed, insomnia sufferers often wake up feeling unrefreshed and experience:
- Fatigue
- Poor concentration

1. Lifestyle & Environmental Triggers
- Shift work or jet lag
- Noise, light or temperature extremes

Diagnosis & Understanding the Problem
1. Clinical Assessment & Sleep Diary
Doctors start with a medical history, symptom discussion and often ask for a 2-week sleep diary to track bedtime, wake time and disruptions.
2. When to Get a Sleep Study
Polysomnography (overnight sleep study) may be recommended if other conditions like sleep apnea, are suspected. These tests monitor brain waves, heart rate, breathing and movements.
3. Identifying Underlying Causes
Thorough evaluation helps to differentiate between psychological, medical and behavioral causes to tailor treatment accordingly.
Evidence-Based Treatment Strategies

CBT-I is the gold standard treatment for chronic insomnia. It includes:
- Stimulus control: Associate the bed with sleep only
- Sleep restriction: Limit time in bed to actual sleep duration
- Relaxation techniques: Breathing, meditation, muscle relaxationCBT-I is recommended by major sleep organizations and has long term benefits, not like sleeping pills which only provide short term relief.
3. Medical & Alternative Treatments
- Prescription medications: Like Zolpidem, Temazepam—best for short term use
- Over-the-counter aids: Like melatonin (limited evidence)
- Alternative options: Acupuncture, mindfulness, CBT-I apps, and acupressure have shown promise
