The purpose of the present study was to examine the relationships of frequency, duration, and intensity of hot flashes with daily stress, ambient temperature, and caffeine, alcohol, and nicotine intake in menopausal women. Ten menopausal women suffering from hot flashes monitored these variables daily for 6 weeks. Intrasubject correlational analyses revealed significant relationships between hot-flash activity and stress for half of the sample; few women exhibited significant relationships between hot-flash activity and other variables. The results are discussed with respect to theoretical implications and treatment strategies.
