How Your Monthly Cycle Affects Sleep and Mood: What You Need to Know
August 11, 2025 • 2 MIN READ
Understanding how your menstrual cycle impacts your sleep and emotions can help you take better care of your well-being.
A recent study, published in The Journal of Sleep Research, looked at how 51 healthy women experienced sleep and emotions over two menstrual cycles. The study showed the relationship between menstrual cycles, emotions, and sleep patterns.
Key findings from the study include:
- Women experience disruptions in their sleep patterns in the days leading up to and during their period (peri-menstrual phase), spending more time awake at night, with a lower proportion of time spent in bed that is asleep (lower sleep efficiency).
- During the peri-menstrual phase, women report heightened feelings of anger compared to other phases of their monthly cycle.
- Sleep disturbances during the peri-menstrual phase correlate with reduced positive emotions such as calmness, happiness, and enthusiasm.
This study tells us that hormones play a big role in how we sleep and, understanding this can help doctors give better advice and support. Tracking our monthly cycle can help with identifying some potential disturbances in our sleep, mood, and productivity.
Overall, knowing how your menstrual cycle affects your sleep and mood can help you take better care of yourself. It's a reminder that our bodies are complex, and it's okay to seek support when we need it.
