Overview
- Blue light from phones, tablets, and TVs at night suppresses melatonin and delays the body clock, which leads to later sleep and more wake-ups, according to Harvard Health.
- Specialists recommend an “analog” hour before bed with dim lights and no screens to lower mental stimulation, and they suggest testing this change for a week to see results.
- Progressive muscle relaxation and slow, deep breathing calm the nervous system and help people fall asleep faster and keep sleep more stable.
- Morning daylight plus steady bed and wake times help retrain the circadian rhythm and improve morning alertness after several days of consistency.
- Mayo Clinic and WHO guidance flags late caffeine, alcohol, heat, and noise as common disruptors, and the CDC advises medical evaluation if problems persist or if loud snoring, breathing pauses, restless legs, or severe daytime sleepiness appear.
