New research reveals Galaxy Watch4 can be used to measure Obstructive Sleep Apnea (OSA)

A study published by Sleep Health, the National Sleep Foundation medical journal, has recently suggested the Samsung Galaxy Watch4 could potentially be used to measure Obstructive Sleep Apnea (OSA). OSA is a common sleep disorder, generally characterized by repetitive narrowing or collapse of upper airway during sleep, resulting in oxygen desaturation, frequent arousals, and increased sympathetic activity. The study found that wrist-worn trackers, like the Galaxy Watch4, were accurate in continuously measuring oxygen levels in trial patients, enabling researchers to screen for OSA by analysing data collected by the wearable. 

In brief, the study compared Galaxy Watch4’s SpO2 measurements to traditional sleep tracking methods. It was conducted by a joint research team at the Samsung Medical Center and Samsung Electronics. The study monitored 97 adults, with sleep disturbances from ages 13-44. Participants were classified with normal, mild, moderate or severe OSA. 

The findings from both the Galaxy Watch4 and conventional methods, were aligned, proving that the Galaxy Watch4 accurately measures oxygen saturation during sleep and that it can be used to screen for OSA. The study concluded that the Galaxy Watch4 could help overcome the high cost and in-hospital requirements associated with traditional measurement tools by monitoring daily sleep patterns directly from a wearable device.

If you’re someone who is concern of your daily health and sleep, the Galaxy Watch4 is excellent for tracking patterns or trends in sleep, and detecting underlying health problems. You should start tracking your sleep using Galaxy Watch4 and utilize its helpful sleep coaching program to improve your sleep quality.
