Insomnia
Mild
Insomnia is a common sleep disorder involving persistent difficulty falling asleep, staying asleep, or obtaining restorative sleep despite having an adequate opportunity to sleep. It can cause daytime tiredness, poor concentration, irritability, reduced performance, and other difficulties. Insomnia may be short term or chronic and can occur on its own or alongside medical, psychological, medication-related, or sleep-related conditions.

When to Seek Medical Attention
Insomnia is usually not an emergency and can often be managed through planned medical assessment and appropriate sleep treatment. Seek care when persistent sleep problems interfere with daytime functioning, mood, concentration, or safety. Prompt assessment is important when severe daytime sleepiness creates a risk of accidents, particularly while driving.

Overview
Insomnia is a common sleep disorder involving persistent difficulty falling asleep, staying asleep, or obtaining restorative sleep despite having an adequate opportunity to sleep.

Causes 1
Insomnia may result from stress, changes in schedule, travel, an uncomfortable sleep environment, or ongoing worries. Chronic insomnia can be associated with anxiety, depression, chronic pain, breathing problems, reflux, hormonal changes, or other medical conditions. Caffeine, nicotine, alcohol, some medicines, and irregular sleep schedules can also interfere with sleep. In some cases, behavioral patterns develop that maintain sleep difficulties even after the original trigger has resolved.
Stress
Risk Factors
Risk increases with ongoing stress, irregular sleep schedules, shift work, travel across time zones, older age, and certain medical or mental health conditions. Caffeine, nicotine, alcohol, some medicines, and poor sleep habits can contribute. A previous episode of insomnia may increase the likelihood of recurrence. People who experience persistent pain, breathing problems during sleep, or other sleep disorders may also have increased risk.
Diagnosis
Diagnosis is based on a patient's medical history,
symptoms, physical examination and, when necessary,
laboratory or imaging investigations.
Diagnosis is based mainly on a detailed history of sleep patterns, daytime symptoms, health conditions, medicines, and lifestyle factors. A sleep diary may help identify patterns and triggers. Healthcare professionals may use questionnaires to assess insomnia and daytime sleepiness. A physical examination or laboratory testing may be used when an underlying condition is suspected. Sleep studies are generally reserved for cases in which another sleep disorder, such as sleep apnea, is suspected.

Key Prevention Tips
Consistent sleep and wake times, a comfortable dark and quiet bedroom, regular physical activity, and limiting caffeine and nicotine later in the day can support healthy sleep
