This study examined college student reports of how often they used various methods to cope with sleepiness, as well as students' rankings of the relative effectiveness of these methods. Results varied with circadian preference. Evening types coped with sleepiness by taking long naps or listening to music more often than intermediate types. Intermediate types coped by exercising or time outdoors more often than evening types. Compared to intermediate types, evening types were less likely to exercise in the morning and more likely to consume caffeine in the evening. Evening types ranked long naps as more effective than intermediate types. Intermediate types ranked exercise and time outdoors as more effective than evening types. Compared to intermediate types, evening types were sleepy more often, exercised less often, and rated their fitness level as poorer. Implications for chronic sleepiness are addressed.
