Sleep deficit is a global problem, with Omagh, Northern Ireland residents being kept awake by a persistent hum and vibration. The Worldwide Hum is only heard by 2-4% of people and is related to low-frequency noise from human or industrial sources such as traffic, ventilation systems, and airplanes. Low-frequency noise disrupts sleep, causing increased light sleep, decreased deep sleep, REM sleep, heart changes, heart disease, depression, anxiety, stress hormone increases, and structural brain changes. Traveling and unfamiliar settings can also disrupt sleep quality, with experts recommending stable wake times, light exposure, and using earplugs or masking sounds to help. Improving sleep quality can mitigate stress and enhance daily functioning, especially during the holidays.
