Most women experience sleep changes across the menstrual cycle. We applied the ultra‐short sleep–wake schedule to healthy females to compare their 24‐h sleep propensity rhythms in the follicular and luteal phases. The daytime (09.00–16.30 h) subjective sleepiness and the number of slow wave sleep‐containing nap trials increased in the luteal phase compared to the follicular phase, but the mean sleep propensity did not change. During the periods of 17.00–00.30 h and 01.00–08.30 h there were no differences between the two phases. These results suggest that increased daytime sleepiness in the luteal phase may be related to brain mechanisms controlling slow wave sleep.
