Agnirva Space Premier League - Expedition #30414: Monitoring Sleep in Space: A Student-Led Innovation in Heart Health Research

Getting a good night’s sleep is important for everyone—even astronauts. But how do you monitor sleep in space, especially when the body behaves so differently without gravity? That’s what the experiment “Cardiac Adapted Sleep Parameter Electrocardiogram Recorder” set out to explore. What’s even more remarkable? This was an educational project led by university students.

Guided by Principal Investigator Dr. Marc O’Griofa at University College Dublin, the experiment was developed in collaboration with the University of Limerick. As part of Expedition 14 aboard the ISS, it aimed to develop and test a wearable electrocardiogram (ECG) device designed to track both heart activity and sleep parameters in astronauts.

In microgravity, the heart doesn’t work the same way as it does on Earth. Fluids shift, the workload changes, and astronauts experience altered sleep patterns. The device created by the students recorded these physiological changes, giving researchers real-time data on how space affects cardiovascular health and sleep quality.

This data is valuable not only for current astronauts but also for planning longer missions, such as trips to Mars. Ensuring that space travelers can rest effectively and maintain heart health is a key step in sustainable human exploration.

Beyond its scientific impact, this project is a stellar example of how students can contribute meaningfully to space research. It highlights the power of educational initiatives to deliver real-world innovation.
