The lower your resting heart rate, the better. True? Why?
In: Biology
A normal resting heart rate for adults ranges from 60 to 100 beats per minute. Generally, a lower heart rate at rest implies more efficient heart function and better cardiovascular fitness. For example, a well-trained athlete might have a normal resting heart rate closer to 40 beats per minute [1].
A grizzly bear hibernates five to six months of the year. During that time, its heart rate slows drastically from around 84 beats per minute when active to around 19 [2].
Therapeutic hypothermia could save lives, propel interstellar travel, and expand consciousness [3].
