What is Insomnia?
Insomnia is a sleep disorder characterized by difficulty in falling asleep, staying asleep, or waking up too early without being able to return to sleep. It can be acute (short-term) or chronic (long-term), lasting from a few days to several months or even years.
Types of Insomnia
- Acute Insomnia: This is usually temporary and often triggered by stress, changes in sleep habits, or environmental factors.
- Chronic Insomnia: Lasting for months or more, chronic insomnia can be caused by underlying medical conditions, psychological factors, or lifestyle habits.
- Onset Insomnia: Difficulty in initiating sleep, often linked to anxiety or stress.
- Maintenance Insomnia: Trouble staying asleep, often waking up frequently during the night.
- Early Morning Awakening Insomnia: Waking up too early and being unable to return to sleep.
Causes of Insomnia
Psychological Factors
- Stress: Work pressure, financial issues, or personal problems can trigger sleep disturbances.

- Neurological Disorders: Diseases like Parkinson’s and Alzheimer’s can contribute to insomnia.
Lifestyle Factors
- Irregular Sleep Schedule: Shift work or frequent travel across time zones disrupts the body's circadian rhythm.
- Excessive Screen Time: Blue light exposure from screens inhibits melatonin production, making sleep difficult.

Effects of Insomnia on Health
- Physical Health Issues: Chronic insomnia is linked to heart disease, high blood pressure, diabetes, and weakened immune function.

- Cognitive Impairment: Poor sleep affects memory, decision-making, and problem-solving abilities.
- Decreased Productivity: Insomnia leads to lower efficiency at work or school, contributing to stress and burnout.
- Weight Gain: Lack of sleep affects hormones that regulate hunger, leading to unhealthy eating habits.
Diagnosing Insomnia
If sleep disturbances persist for more than three nights a week over several months, consulting a doctor or sleep specialist is crucial. Diagnosis involves:
- Reviewing medical history
- Maintaining a sleep diary
- Undergoing sleep studies (polysomnography) to assess brain activity, breathing, and movement during sleep
Treatment Options for Insomnia
Lifestyle Changes

CBT-I is a structured, evidence-based approach that helps individuals identify and change thoughts and behaviors that contribute to insomnia. It includes:

- Over-the-Counter Sleep Aids: Antihistamines and melatonin supplements can help but should not be used long-term without medical guidance.
- Alternative Therapies: Herbal remedies like valerian root, chamomile tea, and acupuncture have been reported to improve sleep quality.
Natural Remedies for Insomnia
- Aromatherapy: Essential oils like lavender and chamomile promote relaxation.
- Herbal Teas: Drinking warm herbal tea before bedtime can aid sleep.
- Magnesium & Calcium: These minerals play a role in muscle relaxation and sleep quality.
- White Noise & Relaxing Sounds: Background noise or soothing music can create a calming sleep environment.
When to See a Doctor
If insomnia becomes chronic, affects daily functioning, or is linked to other medical conditions, seeking professional help is necessary. A sleep specialist can provide a tailored treatment plan.
