Insomnia: what it is, symptoms and treatment

Insomnia is not "just" not sleeping enough. It is a sleep disorder defined by difficulty falling asleep, staying asleep, or waking up too early, with a real impact on the following day: tiredness, irritability, lapses in attention, and decreased performance.

The good news is that insomnia has effective treatment and, in most cases, does not require long-term medication. In this guide, I explain, in simple language, what insomnia is, how to recognize the symptoms, and which approaches really work.

Insomnia: what is it?

Insomnia is a persistent sleep-related difficulty that occurs despite adequate sleeping conditions and causes distress or impairment during the day. It can manifest in three main ways: difficulty in fall asleep (prolonged latency), night awakenings having difficulty falling back asleep and waking up too early unable to fall back asleep.

Duration and frequency: To be considered chronic, insomnia must occur at least 3 nights a week during 3 months or more. If the duration is shorter, we speak of acute or adaptation insomnia.

Important: Insomnia is a clinical diagnosis. That is, it doesn't depend on "sleeping X hours," but rather on the impact on the day and the consistent pattern of difficulties.

Types and classification of insomnia

To better understand the condition and choose the appropriate approach, it is helpful to know the different types that exist:

1. Insomnia at the onset – difficulty falling asleep.

2. Maintenance insomnia – waking up several times during the night.

3. Early awakening insomnia – waking up earlier than desired and not being able to fall back asleep.

4. Chronic vs. acute insomnia – depending on the duration and frequency.
   A correct classification helps healthcare professionals to determine the most appropriate treatment.

Symptoms of insomnia: how to recognize them

Before the list, some context: many people underestimate insomnia because they "get through the day." However, quality of life and mental health suffer cumulatively.

• Taking more than 30–40 minutes to fall asleep on 3 or more nights per week.

• Waking up several times and having difficulty falling back asleep.

• Waking up 1–2 hours earlier than desired and then being unable to fall back asleep.

• A feeling of light, fragmented, and non-restorative sleep.

• Daytime sleepiness, fatigue, morning headaches.

• Irritability, anxiety, depressed mood, and excessive worry about sleep.

• Disruptions in attention, memory, and performance at work/studies.

Causes and factors that maintain insomnia.

Insomnia rarely has a single cause. It usually starts with a trigger (stress, schedule change, illness) and is then maintained by a set of habits and beliefs that unintentionally fuel the problem. Here are the most common ones and why.

• Irregular schedules: Going to bed and waking up at inconsistent times disrupts the biological clock.

• Lights at night and screens: inhibit melatonin and increase surveillance.

• Counterproductive trade-offs: Spending more time in bed, sleeping in late, and taking long naps "steal" sleep at night.

• Rumination and performance anxiety: Trying to "force sleep" and watching the clock keeps the brain alert.

• Substances: Late-night caffeine, nicotine, and alcohol disrupt sleep.

• Associated medical/psychological conditions: Chronic pain, sleep apnea, restless legs syndrome, anxiety, depression.

Not all insomnia is the same: types and profiles

Understanding insomnia profile This helps in choosing the most effective intervention. A brief introduction and an objective list follow.

• Insomnia of initiation: difficulty, especially in falling asleep. Responds well to a winding-down routine, exposure to morning light, and caffeine control. stimulus control.

• Maintenance insomnia: Multiple awakenings. Benefits from environmental optimization (noise, temperature), stress management and, often, sleep compression.

• Terminal insomnia (waking up early): More common in morning types or those with a depressed mood; adjusting lighting and schedules is key.

• Comorbid insomnia: When other health problems coexist, it requires an integrated plan and, sometimes, additional medical evaluation.

Diagnosis of insomnia

Insomnia is diagnosed in clinical consultation Based on sleep history, daytime symptoms, and behavioral patterns. Sleep studies (polysomnography). They are not necessary For most cases, except when other disorders are suspected (sleep apnea, periodic limb movements) or when the condition does not improve with appropriate treatment.

Useful tools for assessment:

• Sleep diary (2 weeks) to record sleep times, wake-ups, and naps.

• Sleepiness scales and anxiety/depression questionnaires when relevant.

If you need a structured assessment and a tailored plan, schedule an appointment. sleep therapy. A guided intervention accelerates results and avoids months of trial and error.

Treatment of insomnia

The basis of effective treatment is... Cognitive-Behavioral Therapy for Insomnia (CBT-I). This is the first-line approach recommended by scientific societies and shows lasting benefits without tolerance effects. Medication may be used in specific phases and for short periods, but it does not address the underlying causes of insomnia.

Pillars of CBT-I (simple and practical explanation)

Before the list, a key idea: CBT-I reorganizes habits, beliefs, and the environment to restore the association between bed and sleep.

• Sleep education: to understand how sleep pressure and the circadian rhythm to adjust expectations.

• Stimulus control: The bed is for sleeping and intimacy; if you are awake and frustrated, leave the room and return when you feel sleepy again; always get up at the same time.

• Sleep restriction/compression: Temporarily reduce time in bed to consolidate sleep. As efficiency improves (> 85–90%), the window is widened.

• Cognitive intervention: Working on catastrophizing and rigid beliefs ("if I don't sleep 8 hours I get sick"), training more functional responses.

• Sleep hygiene focused: Bright light in the morning, dim light at night, limit caffeine, optimize your bedroom, avoid long naps.

• Relaxation techniques: Slow breathing, progressive muscle relaxation, body scan.

And what about medication for insomnia?

Hypnotic and sedative drugs they can They can be useful in the short term (stress crises, acute insomnia), but They are not a lasting solution.. They should be evaluated on a case-by-case basis and used for the shortest time possible, ideally with a weaning plan. in parallel with TCC-I.

Immediate strategies to start today.

If you want to reduce the time you spend awake in bed tonight, start with 3 practical steps. The introduction summarizes the goal: lower arousal and strengthen the bed-sleep association.

1. Set a fixed wake-up time. (including on weekends). It's the anchor of your biological clock.

2. 30–45 minute slowing-down ritualLow light, personal hygiene, light reading, breathing exercises 4-6. Avoid screens, work tasks, and arguments.

3. Rule of getting out of bedIf you don't fall asleep within ~20 minutes (without checking the time), get up and do something calm in low light. Come back when you feel sleepy again.

Insomnia and other disorders: when to investigate further

There are signs that require further evaluation, as they may point to underlying causes that require specific treatment.

• Loud snoring, pauses in breathing, nighttime choking: suspected sleep apnea.

• Uncomfortable sensations in the legs at night and the need to move them: restless legs syndrome.

• Marked anxiety or depression, night panic attacks: To request coordination with mental health services.

• Chronic pain, reflux, dysregulated thyroid: medical conditions that fragment sleep.

Myths about insomnia

Good intentions can solidify bad habits. Here are some common beliefs that hinder efforts to improve insomnia.

• “"Spending more hours in bed pays off." In cases of insomnia, more time in bed increases frustration and worsens sleep.

• “"If I don't sleep 8 hours, I get sick." The need for sleep is individual; focus on regularity and functionality.

• “"Alcohol helps you sleep."” Fall asleep faster, However, sleep becomes fragmented and less restorative.

• “"I have to force myself to fall asleep." Sleep cannot be forced; the right context must be created for it to happen.

When should you seek professional help?

Consult a doctor or sleep specialist if:

• Insomnia persists for several weeks or recurs frequently.

• There is a severe impact on daily life (extreme exhaustion, difficulty concentrating, accidents).

• It is suspected that the cause may be another health condition (e.g., sleep apnea, chronic pain, psychiatric disorder).

• You've already tried applying good sleep hygiene practices and haven't seen any improvements.
  A specialized evaluation helps to rule out complications and determine the appropriate treatment.

Conclusion

Insomnia isn't solved with a single trick. It's solved with a... method which realigns the clock, reduces hyperactivity, and rebuilds the bed-sleep association. CBT-I is the foundation because it addresses the underlying causes of insomnia and teaches lasting skills.

If after 2–4 weeks of consistent practice results have not yet appeared, a consultation with sleep therapy You can transform knowledge into real results with a plan tailored to your life.
