Why it matters
Sleep disruption in the week before your period is extremely common and completely underresearched. Progesterone drops in the luteal phase, body temperature rises slightly, and the combination disrupts sleep architecture in ways that most people don't connect to their cycle because the timing isn't always obvious. Knowing that your sleep is going to be worse in a specific cycle window means you can adjust your expectations, your evening habits, and your recovery strategy rather than spending a week wondering what's wrong with you.
When Normal helps
Normal connects your sleep quality data to your cycle if you're tracking it, or finds the pattern itself from your check-ins over two to three months. It tells you which phase of your cycle most consistently affects your sleep and by how much — so you can plan around it.
How Normal finds it
Tell Normal how you slept every morning and track your cycle. Over two to three months Normal finds the relationship between your cycle phase and your sleep quality and confirms whether it's a consistent pattern for your body specifically.
