ResumoThe present study investigated some differences between ‘morning’ and ‘evening’ types in life habits, particularly concerning meals, ingestion of caffeine and alcohol, and smoking. The Life Habits Inventory and the Japanese version of Home and Östberg Morningness-Eveningness Questionnaire were administered to approximately 1500 students, and data on life habits of the morning types were compared with those of the evening types. Significant differences between these types were found in frequency of night meals, smoking, and ingestion of caffeine and alcohol. Although significant differences were not found for mealtimes, 34.8% of the evening types typically did not eat breakfast. These differences were discussed from viewpoint of chronopharmacology and personality.
