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 ...

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, ...

It’s been known for decades that heart rate variability (HRV) during labor signals how a fetus is responding to stress. Lower HRV—a lower variation in heartbeats—is even a risk factor for sudden ...

Scientists have a lot to learn about the connection between sleep and stress, but one thing is clear: They're both trending in the wrong direction. As revealed in a recent Gallup poll, the proportion ...

It’s no secret that alcohol inhibits overall health, but for runners and other athletes, the risks are even more adverse. Drinking alcohol negatively affects your heart-rate variability (or HRV) and ...

Heart rate variability (HRV) typically increases with parasympathetic activation (rest-and-digest response) and decreases with sympathetic activation (fight-or-flight response). The autonomic nervous ...

It may sound dramatic, but the rate at which your heart is beating plays a key role in how long you’re likely to live. According to expert cardiologists and academic researchers, resting heart rate ...

A post hoc analysis found that the effect of transcutaneous auricular vagus nerve stimulation (taVNS) on cardiac and inflammatory stress responses was critically dependent on variability in baseline ...
