Using the power of wearable data to take the mystery out of the postpartum and improve the lives of new parents everywhere.

Study quantifies the sleep loss and disruption experienced by new mothersA new study to be presented at the SLEEP 2025 annual meeting quantifies the amount of sleep loss experienced by first-time mothers in the weeks after giving birth and is the first to identify the unique type of sleep disruption that persists throughout the first months of motherhood.

Hi there! I am a Clinical Health Psychologist with 15+ years of research and clinical experience in women's health and sleep. About a year after I had my daughter, I decided to analyze my postpartum Fitbit data with the same kinds of research methods I'd been using in my sleep research studies. I was shocked by how clearly my wearable data showed what had happened to my sleep in the postpartum!

I believe that wearable devices (Fitbits/Apple Watches/etc.) are the objective tools needed to take the mystery out of the postpartum and reduce its many health disparities. But I can't get this important research off the ground by myself.

Here's how you can help:

Did you wear a wearable device after the birth of your first child? Consider donating your postpartum wearable data to my IRB-approved research study to help us get the lay of the land for what the sleep of new parents actually looks like.

Send me an email to learn how to donate your postpartum wearable sleep data:
