This episode explores the halachic discussions in Mishnah Berurah on health and medication on Shabbos. Topics include expressing milk for infants, distinctions between medical and non-medical uses of substances, oral hygiene practices, eating foods with healing properties, the permissibility of vitamins, and the use of sleeping tablets. The shiur clarifies when food and medicine may be taken by healthy individuals versus those experiencing discomfort or illness, and how rabbinic prohibitions interact with real pain or need.
