You know, those times when you _mean_ to go to sleep but instead you stay up to watch just one more episode of _Orange Is the New Black_.

They define it as “failing to go to bed at the intended time, while no external circumstances prevent a person from doing so.” Translation: Unlike insomnia, which is when you can’t fall asleep, bedtime procrastination is when you _could_ go to bed, but you willingly put it off and, as a result, you don’t get enough sleep. **Health.com:**[12 Ways We Sabotage Our Mental Health](http://www.health.com/health/gallery/0,,20694928,00.html?xid=Time-procrastination-061614) [_This article originally appeared on Health.com._](http://news.health.com/2014/06/13/how-procrastination-is-messing-with-your-sleep/?xid=Time-procrastination-061614) How Procrastination Is Messing With Your Sleep ```json [{"@context":"https://schema.org","@type":"NewsArticle","@id":"https://time.com/2907373/procrastination-is-messing-with-your-sleep/","mainEntityOfPage":{"@type":"WebPage","@id":"https://time.com/2907373/procrastination-is-messing-with-your-sleep/"},"headline":"How Procrastination Is Messing With Your Sleep","datePublished":"2014-06-22T17:00:29.000Z","dateModified":"2026-02-21T08:33:04.787Z","description":"Whether you’re a night owl or an early riser, sometimes it can be hard to stick to your bedtime.
