City dwellers may have
City dwellers may have trouble falling asleep without the familiar sounds of traffic. Or a traveler may find it difficult to sleep without the familiar tick, tick, tick of the alarm clock at home.
Some noises, although annoying at first, can gradually be ignored, allowing sleep to follow. Studies show people can get used to noises such as city traffic in about one week. However, important noises, like a parent?s baby crying, a smoke alarm or even one?s own name being called, are not easily assimilated and generally snap us awake.
Sleep Affected By Temperature/Climate
The point at which sleep is disturbed due to temperature or climate conditions varies from person to person. Generally, temperatures above 75 degrees Fahrenheit and below 54 degrees will awaken people.
Sleep Affected By Altitudes
The higher the altitude, the greater the sleep disruption. Generally, sleep disturbance becomes greater at altitudes of 13,200 feet or more.
