Circadian and Sleep Monitoring in Blind Subjects with and without Light Perception

Eighteen blind volunteers and 26 sighted controls wore ambulatory monitoring devices for seven days in real-life conditions. The dataset, authored by David Martínez-Martínez and updated in April 2026, likely contains measurements of distal skin temperature, motor activity, light exposure, and feeding schedules to assess circadian health and sleep.

Use Cases

• Compare circadian health metrics like light exposure and physical activity between blind and sighted populations.
• Analyze the relationship between conscious light perception and sleep quality in blind subjects.
• Study behavioral circadian alterations, such as feeding schedules and night fasting duration, associated with blindness.

Strengths

• Includes data from 44 participants (18 blind, 26 controls) with a mean age of approximately 51.5 years.
• Features seven consecutive days of real-life ambulatory monitoring using the Kronowise® device.
• Published under a CC-BY-4.0 license, permitting open reuse and redistribution.

Limitations

• Row count and column-level documentation are unknown, requiring manual inspection after download.
• The dataset is very small at 13.9 KB, indicating limited scope and likely summary-level data.
• Data may reflect bias inherent to the specific volunteer cohort studied.
