Effects of chronic insomnia

Insomnia involves difficulty falling asleep, staying asleep or waking too early, with consequences during the day. Ongoing sleep loss may cause daytime sleepiness, irritability, slower reactions, memory problems and difficulty concentrating. It can make work, driving and caregiving less safe. Sleep and mood influence each other: persistent insomnia may worsen anxiety or depression, and emotional strain can make sleep harder. Burnout can also leave a person exhausted without restoring sleep. Jet lag, pain, medicines, breathing problems and irregular routines may contribute, so the underlying cause matters.

Keep a steady wake time, use the bed mainly for sleep, and allow a calm wind-down period before bedtime. Limit caffeine late in the day, reduce bright screens near bedtime and keep the room quiet, cool and dark. If you remain awake and frustrated, get up briefly for a quiet activity and return when sleepy. Record sleep, naps, substances and symptoms for discussion with a clinician. Cognitive behavioural therapy for insomnia may be considered; sleeping tablets are not suitable for everyone and should be discussed before use.

Arrange a medical review when poor sleep persists, affects work or relationships, or causes daytime sleepiness and concentration problems. Seek prompt help for falling asleep while driving, severe mood change, thoughts of self-harm, or unusual periods of very high energy with little need for sleep. A clinician can check for another sleep or mental-health condition.

Ask what might be keeping you awake, whether another condition or medicine is involved, and whether a structured insomnia treatment is appropriate. Bring a sleep diary and describe snoring, breathing pauses, naps, mood and daytime safety concerns.
