Summary
Rav permitted Rav Acha Bardela to sleep in a canopy bed in the sukkah [the canopy was flat roofed and 10 tefachim high, which is considered problematic according to all opinions (see 8.5-9.2)] because the mosquitoes were bothering him.
Rava permitted Rabbi Acha bar Ada to sleep outside of the sukkah because he was bothered by the odor of the soil. This is in accordance with the opinion of Rava: One who is distressed is exempt from sukkah.
Challenge: The mishna says that only people who are sick and their attendants are exempt, not just anyone who is distressed?
Resolution: When someone is sick his attendants are exempt as well, when he is in distress, only he is exempt.
Mishna 21.2: Eating and drinking casually is permitted outside of the sukkah.
Question: How much is considered ‘casual’?
Rav Yosef: The volume of 2-3 eggs.
Abayye to Rav Yosef: People are often satiated with that amount and it should be considered a full meal?
Abayye: The amount that a talmid chochom eats as he rushes out to the shiur (Tosfos explains that it’s the volume of 1 egg).
Beraisa: Eating a little bit, casually, is permitted outside of the sukkah but sleeping a little bit is forbidden.
Question: Why is a little sleep forbidden?
Rav Ashi: Because we’re concerned that he may end up oversleeping.
Abayye to Rav Ashi: What about this beraisa: “One may take a quick nap in his tefillin, but he may not go to sleep in them”. Why isn’t the beraisa concerned he may oversleep?
Rav Yosef brei D’rav Ilai: The beraisa of tefillin is discussing a case where he asked someone to wake him.
Rav Mesharshia: “Your guarantor needs a guarantor!” The waker may also fall asleep.
Rabbah bar bar Chana quoting Rabbi Yochanan: The beraisa of tefillin is discussing a case where he put his head between his knees (he is sleeping in an uncomfortable position and is bound to wake up).
Rava: There is no differentiating between “sleep”s [a nap and a sleep are the same thing].
We learn in one beraisa (1) “One may take a quick nap in his tefillin, but he may not go to sleep in them”. Another beraisa (2), “You can even sleep a real sleep”. Another beraisa (3), “You can’t even nap”. 3 refers to a case where he’s holding the tefillin in his hands so he can’t even nap lest he drop them. 1 refers to a case where he’s wearing the tefillin, if he sleeps for a while we’re concerned he may pass gas while wearing the tefillin. 2 refers to a case where the tefillin are near him and he covered it.
