Cloth color preference under the influence of menstrual cycle.

The aim of this study is to know the effects of the menstrual cycle on cloth color preference in 10 normal menstruating subjects. They were instructed to choose a single one out of 41 cloth colors (24 x 52 cm), preferred by themselves, every five minutes from 06:30 h to 08:00 h under the ambient temperature (Ta) of 28 degrees C. A warmer cloth color was preferred in the luteal phase compared with the follicular phase. The findings that the warmer cloth color preference occurred in the luteal phase could probably be interpreted in terms of an establishment of a higher setpoint for core temperature.
