Editing Sleep (section)

== In Halacha ==
Before sleep, we customarily say the bedtime Shema and the blessing of Hamapil, after which one should not speak. The Rambam wrote in his book that one needs to relieve oneself before and after sleep.

It is accepted from Chassidim that before sleep, they are particular about the order of action, speech, and thought: Preparing netilas yadayim by the bed - action, saying the bedtime Shema - speech, and after the blessing of Hamapil thinking Tanya by heart until falling asleep - thought.

And waking up in the order of thought, speech, and action: When awakening, thinking about how the King of kings stands over him - thought, saying Modeh Ani - speech, and washing hands - action.

The sleep that a person needs is one-third of the day - eight hours.
