Does falling asleep with your T.V. on negatively affect your circadian rhythm? 

I've done it for quite a few years now, and don't have the best sleeping habits (being a Redditor doesn't help either). Just curious if it would help to stop the habit.

Are you asking if the light coming from the tv set is messing with your circadian rhythm? 

There are some studies in teens showing that the more electronic equipments kids have in their room, the less they sleep. This considers tvset, computers, videogames etc. The rationale is that having a distraction in your bedroom will delay your sleep time. 

If you have problems sleeping, then it's probably for a similar reason rather than for the light emitting from your tv screen. It is possible to affect circadian output (as measured with melatonin in the urine) by modifying light exposure but it's controversial how important that is. For instance you can adjust circadian rhythm in shift workers by reducing their "bedtime" light exposure but this will not improve their overall feeling.
