These days, it may seem like there’s a million different data points that you’re supposed to keep track of—hello, steps, sleep, and recovery scores!—and it’s difficult to know which ones are worth ...

New research links warmer nighttime temperatures to impaired heart recovery in older adults, highlighting a critical health ...

The estimation of respiratory rate (RR) using photoplethysmography (PPG) and electrocardiogram (ECG) signals has emerged as a critical research area with substantial implications for clinical ...

Heart rate, an essential indicator of overall health and well-being, is traditionally measured by counting the number of cardiac pulses within a specific timeframe. Existing methods, however, require ...

What Does a High Resting Heart Rate Mean? The ups and downs of HRV can be so tricky to navigate, in fact, that most doctors, even cardiologists, don’t factor it into treatment plans for their patients ...

Heart rate variability (HRV) is the variation in the time between two consecutive heartbeats over a specific period. Doctors may use HRV as an indicator for certain aspects of a person’s health, ...

Heart rate variability typically decreases during stressful situations, although the heart rate increases. Managing stress levels can mean a more variable heart rate. Exercise and relaxation ...

A recent study showed that the heart rate variability of a dog and its owner adapt to each other during interaction. High heart rate variability is associated with relaxation, while low heart rate ...
