Maimonides' Regimen of Health, a treatise on hygiene,was written in 1198 for the Egyptian sultan Afdal Nur al-Din Ali, who suffered from attacks of depression accompanied by physical symptoms. Maimonides teaches that physical convalescence is dependent on psychological well-being and rest. He stresses the necessity of hygienic conditions in the care of the body, physical exercise, and proper breathing, work, family, sexual life, and diet, and suggests that music, poetry, paintings, and walks in pleasant surroundings all have a part to play toward a happy person and the maintenance of good health.
