Have you ever fallen asleep watching a YouTube video and then, hours later, woke up to find that the following video kept playing automatically? If so, you most likely require a sleep timer, which is fortunately something that YouTube now offers.

However, only YouTube Premium subscribers may access it. Moreover, it is a test feature that is experimental. Most unpleasant of all, the test is only available until September 2. It's completely unknown at this point if the function will remain experimental or permanently disappear after that and eventually make its way onto YouTube.


Go to this page to enable the sleep timer if you have a Premium subscription and would want to give it a try. After that, you can adjust the sleep timer to the desired frequency after which playback should cease by navigating to the settings menu when a video is playing on your phone or laptop. That's how simple it is. Now, let's hope that this continues and is more than a one-time experiment.
