Why sleep data specifically:
Sleep is when the brain consolidates memory, repairs cellular damage, regulates hormones, and processes emotional experiences.
The biological signals during sleep are richer in diagnostic information than any waking measurement.
Clinical EEG during sleep:
Used to diagnose epilepsy, sleep disorders, early cognitive decline, PTSD markers.
AI models trained on high-quality sleep EEG:
Could enable earlier disease detection,
personalised cognitive enhancement,
non-invasive mental health monitoring.
The data is generating itself.
