598 advises me 1. To drop all mental work and worry and absolutely loaf during the rest of my stay in the Arctic. 2. To take very moderate exercise, in the open air, in good weather. With the returning light and on favorable days, gentle hill work may be undertaken at a very slow gait and with watchfulness against extreme exertion or dizziness. 3. To avoid exposure to cold by wearing suitable clothing. The cold and general conditions in the Arctic and of this cruise seem to be largely responsible for the acuteness or accentuation of my trouble. 4. To reduce consumption of tobacco to at most two pipefuls daily, preferably after meals. 5. To take a light meal about an hour before bedtime, including a warm drink if possible, in addition to the regular meals.
