The relaxation brought about by "fluctuation"
Posted by 良請川
Have you ever felt your own pulse?
I'll show you how easily.
Find the pulse of your radial artery on the thumb side of your left wrist.
Then, using the tips of your 2nd, 3rd, and 4th fingers of your right hand, can you feel it as shown in the diagram on the right?
As an internist, I understand subtle sensations.
By slightly pressing with the second finger, and feeling the degree of pulsation with the third and fourth fingers, one can generally determine blood pressure.
1. Three Pulse Patterns Indicating Psychological State
~Relaxation indicated by heart rate variability~
Here's a simple experiment.
First, try to slowly and deeply inhale.
At that time, how does the speed of your pulse rhythm change?
Next, slowly exhale.
Observe the change in your pulse then.
When you inhale deeply, the pressure in the right atrium of the heart becomes negative, and a large amount of blood from the entire body returns to the heart.
Therefore, the heart sends blood to the body slightly earlier.
The opposite happens when you exhale.
The important point is "fluctuation."
The rhythm is mostly regular, but there's a slight instability and irregularity.
In fact, this "fluctuation" becomes a healing rhythm for humans.
Simply saying, "I see, I understand!" is not quite enough.
In medical research, some factor must be measured, recorded numerically, and compared.
Three Patterns Indicated by Heart Rate Rhythm Fluctuation
The heart contracts because electricity flows through it, and I will show the waveform of an electrocardiogram.
When we examine and analyze 100 intervals between the peaks of the highest R waves,
three patterns can be observed.
1. Healthy individuals: Heart rate rhythm slightly speeds up and slows down, with appropriate "fluctuations."
2. Diabetic patients: People with reduced nerve function cannot regulate subtly, resulting in fewer "fluctuations."
3. Relaxed individuals: The parasympathetic nervous system is dominant, leading to larger "fluctuations."
Recently, it has become possible to measure the degree of tension and relaxation in this way.
2. Healing brought by swaying and vibration
~The pleasant sensation of the body trembling~
Now, try to recall when you were a baby.
You might not remember, though.
However, you'll understand if you observe the behavior of infants of family or acquaintances.
Babies are held by their mothers, gently rocked, and sleep comfortably.
Swaying approximately 30cm back and forth, with a rhythm of about two seconds per round trip, is pleasant.
Imagine a baby in your arms and rock it to this rhythm.
"Oh, this feels just right."
Next, try rocking it at twice the distance, 60cm, and one second per round trip.
You'll get dizzy and laugh, won't you?
For everything, there's a perfect timing.
Children love toy trains.
They follow things moving in front of their eyes.
When they get a little older, they enjoy riding in cars or trains.
This is because they feel the engine sounds and vibrations with their ears and bodies, and these stimuli are comforting.
Some people yearn for trains during adolescence and youth.
Perhaps it's because it's an opportunity to escape daily life and travel, to experience a "new world."
