There is a halachah that “mitzta’er patur min ha-sukkah – One who feels discomfort is patur (exempt) from the sukkah.” 

Aside from the normal interpretation, perhaps Chazal are teaching us something deeper:

A person who finds himself in distress, “patur” – is able to free himself, both mentally and physically. How? “min ha-sukkah – From the sukkah” – by correctly performing the mitzvah of sukkah!
