Circadian and Sleep Data from Blind and Sighted Subjects Using Ambulatory Monitoring

Table 3_Circadian system functional status and sleep in blind subjects with and without conscious light perception.docx contains data from a study of 44 participants (18 blind, 26 sighted controls) aged approximately 51.5 years. Author David Martínez-Martínez published the dataset on figshare in April 2026 under a CC-BY-4.0 license. The data was collected using the Kronowise® ambulatory circadian monitoring device over seven consecutive days in real-life conditions.

Use Cases

• Compare circadian health metrics like distal skin temperature and motor activity between blind and sighted populations.
• Analyze the relationship between declared light perception and patterns of light exposure and physical activity.
• Investigate feeding schedule differences, such as timing of the last meal and night fasting duration, in blind participants.
• Assess the degree of chronodisruption by examining the crosstalk between internal time and external synchronizers like light and activity.

Strengths

• Data includes a specific understudied population of 18 blind volunteers with diverse blindness aetiology.
• Multimodal ambulatory monitoring captured distal skin temperature, motor activity, light exposure, and feeding schedules over seven days.
• Includes a control group of 26 sighted volunteers for direct comparison.

Limitations

• Row count and column-level documentation are unknown, requiring manual inspection after download.
• The dataset is very small at 15.4 KB, indicating limited scope.
• Geographic and institutional origins of the participants are not specified.
