Sleep is a cornerstone of health, occupying roughly one-third of our lives—about 25 years for someone who lives to 75... The Withings App 7.5 introduces advanced metrics such as Heart Rate Variability (HRV), Respiratory Rate, and Sleep Movement Rate... By monitoring these metrics with devices like ScanWatch 2 and Sleep Analyzer, and combining them with professional medical advice, we can optimize health and promote a longer, healthier life.
