2. Night Noises
WorldSleepDay.org notes, “intermittent sounds—such as an occasional honking or revving car—is more disturbing than continuous noise”. That’s a big deal if you live in a more urban area, as these sounds never stop. The source notes that for some people, this could lead to lack of sleep and mood disorders.
While it’s difficult to stop cars from honking at midnight (you can’t be out there in your pajamas yelling at drivers), you should at least cut indoor distractions by putting devices on silent (or removing them from your bedside) and turning off the television, suggests the source.
