Circadian rhythm disruptions can be temporary, caused by travel across time zones or a  change in a person's working schedule. Poor sleep habits, such as late-night exposure to blue light through electronic devices, are another potential cause for a sleep disorder. Developing sleep habits can help a person get their sleep schedule back on track.
However, certain genes can determine whether an individual has an easier time falling asleep late or waking up early. While it’s possible for an individual with a preference for a late night’s rest to work hard and become an early riser, there is no way to change genetics.
