• Resumen

  • This study sought to compare the effectiveness of one of the top-selling activity wristbands, the Xiaomi Mi Band 5, with polysomnography in the measurement of sleep stages. Conducted at a hospital in A Coruña, Spain, this study recruited individuals already participating in a polysomnography study at a sleep unit. The study encompassed a total of 45 adults. The Xiaomi Mi Band 5 demonstrated an overall accuracy. Notably, it tended to overestimate total sleep time, light sleep, and deep sleep compared to polysomnography. Conversely, it underestimated wake after sleep onset and REM sleep measured by polysomnography. The Xiaomi Mi Band 5 holds potential as a tool for monitoring sleep and identifying alterations in sleep patterns, especially among individuals without sleep disorders. However, further research is warranted to evaluate its efficacy when used with individuals suffering from various types of sleep disorders
