What causes difficulty sleeping?

Trouble falling asleep or staying asleep may follow travel, shift work, late screens, caffeine, alcohol, noise, or an irregular bedtime. Burnout and Generalised Anxiety Disorder can keep the mind alert, while depression may change sleep timing, energy, and early-morning waking. Acid reflux can cause burning or coughing when lying down. Restless Legs Syndrome can create an urge to move the legs that becomes stronger at rest. Hyperthyroidism may be associated with heat intolerance, tremor, palpitations, and reduced sleep. Pain, breathing problems, menopause symptoms, and some medicines can also disturb rest.

One difficult night is different from a recurring pattern. Keep track of bedtime, waking, naps, substances, symptoms, and daytime sleepiness; this helps distinguish a short-lived trigger from a problem that needs assessment.

Keep a regular wake time and allow enough time for sleep. Use the bedroom for sleep and wind down with dim light and a quiet routine. Limit caffeine later in the day, avoid heavy meals close to bedtime, and keep alcohol from becoming a sleep aid. If you are awake for a long time, move briefly to a calm activity and return when sleepy. Insomnia Management can help build a structured approach. Review new medicines with a clinician rather than changing them yourself.

Arrange an appointment when poor sleep keeps returning, affects concentration or mood, or leaves you struggling to function safely. Seek prompt help for severe anxiety, hopelessness, thoughts of self-harm, several nights with unusually high energy and little need for sleep, or sleepiness that makes driving unsafe. Snoring with pauses in breathing, choking at night, chest symptoms, or persistent palpitations also deserves medical assessment.

Could my symptoms, medicines, mood, hormones, reflux, or leg sensations be disrupting sleep? Should I keep a sleep diary? Which treatment is suitable for my pattern?
