Cohort study, 2013

How do menstrual cycle phase and hormonal birth control affect sleep?

Women on hormonal birth control had better sleep quality and fewer breathing interruptions during sleep compared to women not on birth control. The effect of birth control was stronger than menstrual cycle phase.

Moderate study design 297 premenopausal women in São Paulo, Brazil

What they did

A study of 297 women in São Paulo, Brazil. Researchers gave them questionnaires, measured hormones in blood, and recorded their sleep overnight with equipment.

What they found

Women on hormonal contraceptives had lower breathing interruptions (1.1) compared to follicular phase (2.2) and luteal phase (2.9). Women on hormonal contraceptives also tended to sleep more efficiently. Women in the follicular phase reported more fatigue than those in the luteal phase or on birth control.

What it means for you

Birth control appears to help women sleep better by reducing breathing interruptions. However, this was one study in one country with 297 women, so results might not apply to all women or all settings.

Breathing interruptions on birth control
