Actigraphy

Actigraphy is a non-invasive method used to monitor and measure sleep and activity patterns using a small device called an actigraph, usually worn on the wrist like a watch. It detects and records movement over time, helping to assess sleep quality, duration, and daily activity levels. This data provides insights into a person's rest habits and can aid in diagnosing sleep disorders or monitoring lifestyle changes. Actigraphy is convenient, objective, and useful for capturing real-world behavior over extended periods.
