Behavioral performance changes according to menstrual cycle phase are affected by light exposure


  • Women in the follicular phase of the menstrual cycle had slower reaction times and more inattentional errors than women in the luteal phase, but this impairment in the follicular phase was mitigated by light exposure.

Why this matters

    Menstrual phase should be a consideration when assessing neurobehavioral performance changes and sleep loss in women.
