How does LifeWatch Generation 2 measure my sleep mode?


Based on your heart rate, blood pressure and motion, LifeWatch Generation 2 will determine your sleep mode, specifying the percentage of deep and light sleep.

LifeWatch Generation 2 can also monitor your REM Sleep time when the 24h Atrial Fibrillation (AFib) feature is on.

Please note: The REM Sleep service is only available if you have an active monthly subscription.
