A circadian rhythm disorder happens when a child’s sleep-wake cycle becomes out of sync. The circadian rhythm, sometimes called the body clock, affects hormones, body temperature and sleep over a 24-hour period. Individual circadian rhythms may differ slightly, but all are influenced by exposure to light (day) and darkness (night).
An infant’s (birth to 1 year*) circadian rhythm begins to develop around six weeks of age and is usually set between three and six months. Changes in hormone levels during adolescence (age 10 to 19 years**) can affect a child’s circadian rhythm.
