When the heart beats fast, we perceive time as long. when the heart beats slow, we perceive time as short. Time and the world are relative.

【Turns out that the instantaneous time a person feels stretches and shrinks under the influence of their heartbeat!】


・In a new study, a team of researchers from Cornell University in the U.S. reports that human perception of “very short periods of time, less than one second,” varies depending on heart rate.

・The cardiac cycle of an elephant is 3 seconds, that of a human is approximately 1 second, and that of a normal mouse is 0.2 seconds. These differences in heartbeats also affect the perception of time.

・The study found that the same person perceives time differently depending on changes in heart rate

・Since a person’s perception of time inevitably reflects his or her state of mind in relation to time, we tested the time in a very short period of time (less than one second), with no room for emotions or thoughts, in order to eliminate these various factors and to examine whether the physiological rhythm of the heartbeat is enough to change the sensation of time.

・Participants perceived the sound as longer than it actually was immediately after their heart rate increased, and perceived it as shorter immediately after their heart rate decreased

・In other words, the perception of time was found to stretch and contract in response to slight changes in heart rate

・It seems that we humans experience more fluctuations in our sense of time in a shorter span of time than we think.



The above is a quote and reference from the article.




Time and the world are relative (differential). What is more important to our sense of time may be our emotions rather than our heart rate.


We often hear that elephants, humans, and rats have different speeds of feeling time. (Heart rate speed affects)


In this study, it was found that even in the same person, if the heartbeat speed changes, the speed of time felt also changes.



Indeed, for example.

It is somewhat imaginable that a person with a 60 Hz (heart rate 60) hearing a 100 Hz sound would hear the sound differently than a person with a 120 Hz (heart rate 120) hearing a 100 Hz sound.


Is this imagination (feeling) possible because I am a musician? Do you think the general public would understand this feeling?


To use a different metaphor.

The way you see a train going 60 km/h while looking at a train going 100 km/h alongside you is different from the way you see a train going 120 km/h while looking at a train going 100 km/h alongside you.

、It’s like that.^^


Your analogy sounds like the theory of relativity.

This study may be something that touches on that area.

This research may also explain the slow-motion sensation of encountering an accident, the sensation of an athlete’s ball coming to a stop, and various other such sensations of time.

This world of relative and differential senses may not be just about time!


When I am sad, the world seems to be happy; when I am standing still in shock, the world seems to be busy moving without me.


This is a world of relativism and difference in emotion.


Since emotions also have a significant impact on our sense of time, it makes sense that in the above study, you tried to eliminate emotions (thoughts).


So, I was just thinking about it.

Exciting and fun times go by so fast, don’t they?

When you are excited and having fun, your heart rate is likely to be elevated, so from the perspective of the above study, you may feel that time is slowing down, but it is not. That is a contradiction. But we can assume that this is because the feeling of excitement and fun has a greater influence.


Taking all of this into account, I think


Time and the world are determined by the relativity (differentiality) of heartbeats and the relativity (differentiality) of emotions (thoughts), but emotions (thoughts) have a greater impact than heartbeats

This hypothesis might be made.


Once again, feelings and thoughts are still important in determining how the world should be.


as above

Somehow, from talking about heart rate and time, we ended up talking about how feelings and thoughts are still important.^^


See you then.



A fast heart rate makes time (sound) feel longer, and a slow heart rate makes time (sound) feel shorter.This seems to apply to my various phenomena.
