The mitzva to enjoy Shabbat includes getting a good night’s sleep. A person who normally sleeps for seven hours a night, on Shabbat should sleep for eight to be well-rested and refreshed. However, one should not sleep less on Thursday and Friday with the idea of making up for the lost sleep on Shabbat, as this reduces Shabbat to a catch-up day in service of the weekdays. Moreover, it is preferable not to create a pattern that enslaves oneself to mundane matters the next week, and once again enter Shabbat in a sleep-deprived state. It is best to begin Shabbat feeling refreshed, which makes it easier to concentrate when studying Torah and praying, and easier to enjoy the meals tranquilly with the family. One who does start Shabbat tired, may make up for lost sleep on Shabbat, but should not plan to do this from the outset.
