Our heart rate can be not only a health indicator, but also an indicator of time perception.
The heart has long been called our “stopwatch”. Now a new study shows why this may be more true than we previously thought. Researchers at Cornell University have shown that our perception of time changes with the duration of our heartbeats.

For some adults with an average heart rate of 60 beats per minute, the heart can be a pretty handy built-in timer. But a new study out of Cornell University shows that even for those who don’t have such an accurate heart rate, it can still affect the heart’s perception of time.
Saideh Sadeghi, lead author of the study, a PhD student in psychology, describes how he and his colleagues came to this conclusion. They conducted an experiment in which 45 subjects aged 18 to 21 were attached to electrocardiogram (ECG) machines designed to measure each heartbeat and the interval between them to the millisecond level. They also hooked up an EKG machine to a computer programmed to beep every 80-180 milliseconds with each heartbeat.
In humans, even with the most stable heartbeats, there is very little difference in the duration of each heartbeat. The researchers wanted to know whether this difference would alter the participants’ perception of time.
It turned out that immediately after a shorter heartbeat, the subjects perceived the sound to be longer than it actually was. The reverse is also true: when the heart beats longer, the tone is perceived as shorter. Because the response to tones is directly related to small changes in heart rate, the researchers concluded that our heart rate is very closely related to how we perceive the world, especially time. They called these changes in perception “temporary wrinkles.”
“The heartbeat is the rhythm our brain uses to sense time, and that rhythm isn’t linear—it’s constantly contracting and expanding,” said study co-author Adam K. Anderson, a professor of psychology at Cornell University and the College of Humans. Ecology. Our perception of time fluctuates over time periods. The effect of the heart from one beat to the next helps create a sense of time.”
