If you have problems sleeping, it might not just be your habits that are causing a problem — something might be wrong with your body's natural clock. There are a number of signs that you have a circadian rhythm disorder, and generally these involve issues falling asleep and waking up when you need to. Your body operates on a daily rhythm of temperature and hormone levels that regulate when you go to sleep and wake up, and when this rhythm is off course, it can severely disrupt your sleep patterns.
"[A circadian rhythm disorder] is when your biological clock is out of sync with your environment, like jet lag when you are not traveling" clinical psychologist and sleep doctor Dr. Michael Breus, tells Bustle. "There are many types, including Advanced Sleep Phase Syndrome, Delayed Sleep Phase Syndrome, non-24 hour sleep syndrome, etc."
Although each disorder differs slightly, they all involve a problematic shift in your sleep/wake cycle. This can be caused by something going on internally, but it can also be a result of something external, like jet lag or shift work, according to Merck Manual. Getting to the root of your circadian rhythm disorder is important, as it can have long-term effects, including greater risk of cardiovascular and metabolic disorders.
If your sleep is out of whack and your schedule has been off, you may have a circadian rhythm disorder. Here are six signs to watch out for, according to experts.
