Ep207 - Sleep Data Revolution: Using AI to Detect Patterns, Health Risks, and Improve Sleep Quality with Mikael Kågebäck, PhD

AI Revolutionizing Sleep Health: "Everyone's sleep is different and everyone needs different suggestions to optimize their sleep to make it better if they want to."

In this episode, Dr. Yishan explores the intersection of cutting-edge technology and sleep health, diving deep into the ways artificial intelligence is shaping the future of sleep research and care. Joining the conversation is Mikael Kågebäck, Chief Technology Officer at Sleep Cycle and a specialist in AI and machine learning. Together, they discuss how large-scale AI-powered data collection—using just the audio from your phone—can help us understand sleep patterns, pinpoint global trends, and even potentially identify early warning signs of health issues like respiratory illness and sleep apnea.

Mikael Kågebäck, Chief Technology Officer at Sleep Cycle, holds a Ph.D. in AI and Machine Learning from Chalmers University of Technology, Gothenburg. Steering Sleep Cycle's technical direction, he spearheads essential machine learning research, leveraging his extensive background in tech, AI and ML, with a particular focus on deep neural networks. Bringing diverse experience as a seasoned system architect and software engineer, Mikael actively drives Sleep Cycle's technological innovation, shaping the future of sleep technology.

Mikael Kågebäck shares fascinating insights from Sleep Cycle’s global user base, including how sleep habits vary around the world and what the pandemic taught us about sleep regularity. He also opens up about the rigorous privacy and security protocols that keep users’ data safe, and gives us a peek into the app’s innovative features, such as its real-time “cough radar” and advanced sleep staging.

Whether you’re curious about the technology behind sleep trackers, the benefits (and limits) of AI in sleep medicine, or the future of personalized sleep coaching, this episode is packed with expert knowledge and intriguing possibilities. So get ready to find out how your phone could become your best ally in achieving better sleep—thanks to the power of AI!

Here are 3 key takeaways:

Privacy-First AI Sleep Analysis:
Sleep Cycle uses on-device processing to ensure user audio stays private and secure. All neural network-driven sleep analysis happens on your phone—your audio never leaves the device.

Global Sleep Insights at Scale:
By aggregating anonymized data from millions of users across 180 countries, Sleep Cycle can identify sleep trends (like pandemic-related changes and cultural differences in sleep patterns) and support large-scale research, including studies on Alzheimer’s and respiratory health.

Health Monitoring Beyond Sleep:
AI tracks breathing rates and nightly coughing, creating real-time, location-based “cough radar maps.” These insights enable early detection of respiratory illnesses and can even serve as public health tools—helping predict outbreaks and allocate resources days or weeks ahead.


“And sleep is one of the pillar of our health. Right. And I think if we sleep better and impact our mood, our physical health, our mental health is just so important." - Mikael Kågebäck, PhD
