The condition of the heart can be presumed by the color of nails.
(1) Squeeze the nail part of an index finger for about 5 seconds.
(2) Release the index finger in 5 seconds.
(3) Observe the color of the nail.
(4) Count the time to return to the original reddish nail from whitish nail (Fig. 1).
If the time was within 2 seconds, you could survive when the coronary artery was clogged.
If the time was more than 2 seconds, you couldn’t survive.
11 persons with the ages of 60s attended the experiment.
6 persons’ nails returned to the original reddish color within 2 seconds and according to an ultrasound examination, all 6 persons’ hearts were softer and younger than their ages.
On the other hand, 5 persons whose nail didn’t return to the original reddish color within 2 seconds had harder and older heart than their ages.
What is the relationship between the color of nail and the condition of the heart?
What is observed from the nail color returning test is the condition of capillaries.
Capillaries deliver nutrition and oxygen to the whole body. The length of capillaries, if they are all connected, is about two and a half rounds of the earth.
If capillaries can be confirmed clearly, it proves that the function of capillaries and the blood flow is maintained.
The capillaries in the nail of the person who took 1.8 seconds to return to the original color are clearly seen (Fig. 2-Left).
On the other hand, the capillaries in the nail of the person who took 4 seconds to return to the original color are not clearly seen (Fig. 2-Right).
The condition of the capillaries in the heart can be analogized from the finger.
Maintaining the function of capillaries is the secret to invigorate the heart.
The capillaries maintaining the function decrease with age.
If the function of capillaries declines, nutrition and oxygen don’t reach throughout the heart, and the risk of heart diseases becomes higher.
On the contrary, if capillaries are active, there is a possibility that you can survive even if a coronary artery is clogged.
99.9 % of blood vessels in our body are capillaries.
The heart requires large amount of oxygen to expand and contract, so the heart has more capillaries than other organs (Fig. 3).
Characteristics of capillaries
Con: The function of capillaries declines with age.
By aging, blood can’t pass through capillaries or capillaries disappear.
Pro: New capillaries can be created (Fig. 4 & 5).
When a coronary artery is clogged and the heart doesn’t have enough oxygen, new capillaries extend from another carotid artery to the clogged coronary artery in order to deliver blood to the area where oxygen is insufficient.
How to elevate the function of capillaries
There is nutrition that elevates the function of capillaries and prevents heart attack.
The nutrition is Taurine.
Taurine is rich in seafood, especially in shells, octopus, squid and blue back fishes.
