Should one say birchas haTorah when one wakes up Shavuous afternoon after going to sleep from staying up all night? If not, is there anything one should do to help the situation?
Answer:
Although authorities write that one should recite birkas ha-Torah after sleeping during the day (this is one opinion cited in Shulchan Aruch, Orach Chaim 47), and the Mishnah Berurah (47:25) rules that one who recites it “does not lose out,” the common custom remains not to recite birkas ha-Torah after sleeping during the day.
For Shavuos, some write that it is proper, even according to our custom, to recite the blessing after sleeping during the day, because this is the main sleep of the day (see Teshuvos Vehanhagos, Vol. 3, no. 149).
However, many still do not recite the blessing. This is presumably based on the rationale mentioned in Magen Avraham (47:12), whereby birkas ha-Torah was enacted to be recited once a day, in the morning. According to this, sleeping in the day, even when this is the main sleep of the day, does not obligate a new blessing.
To “help” in this situation, it is advisable to have explicit intention that the blessing made in the morning should exempt even the time after one awakens from the daytime sleep.
