Halachot of Sleep: Difference between revisions

# One is not meant to sleep longer than 8 hours or less than 6 hours, one may vary within those parameters according to one's needs. <ref> Some sources suggest that one should sleep 8 hours such as the Rambam (Deot 4:4) and Orchot Rabbeinu (1 pg 189, biography of the Steipler). Some quote Mishna Brurah 1:9 to argument that one should sleep as much as one needs. If one however reads the whole sentence, one will see that the Mishna Brurah is speaking there about someone who is weak and afraid should they not get enough sleep it will result in them falling asleep during [[davening]]. Baer Heitev 1:6 says the correct amount of sleep is a subjective measure and some people may need more than others. Yalkut Yosef (edition 5764, vol 1 pg 64) writes that it is unhealthy to sleep more than 8 or less than 6 hours. Aruch HaShulchan says that some learn from the pasuk "Yashanti Az Yanuach Li" that one should sleep 8 hours because the gematria of Az is 8 and others maintain since the gematria (mispar katan) of Li is 4 one should sleep 4 hours, but concludes that it all depends on the health and age of the person. </ref>
