This question has long been, answered more than 2000 years ago in the Yellow Emperor's Internal Canon. Huang Di asked Qibo ah, he said, what is the diagnosis of the pulse.

What is the diagnosis?

Qibo said: Diagnostic method is often to Pingdan, Yin gas is not moving, Yang gas is not scattered, diet is not in, the meridians are not full, the collateral veins are well adjusted, the qi and blood is not messed up, so it is possible to diagnose the pulse of the past.

The translation of this passage is that this pulse diagnosis is the best for Pingdan, which is just after dawn, in the morning.

At this time the Yin Qi has not yet moved, Yang Qi has not been scattered, diet has not entered, so the meridians are not yet full, the veins are uniform, but also relatively calm, this time is the most reflective of the body's original situation.

Take the pulse, mainly to take the pulse of disease? That is, too much and too little, that in such a calm state, and without the interference of diet and exercise, etc., the most reflective of the person originally this body's condition.

What can you do at this time? It is also possible to diagnose the sick Mai.

Or is it our reality that pulse diagnosis, it's not possible to do that. It's an ideal state of affairs, unless a doctor on the ward has the opportunity to take a pulse like that.

Therefore, in the absence of such an ideal state, pulse diagnosis requires the patient to be calm, physically and mentally quiet, so that it can be closer to reflecting the original state of the patient.

Being that many people are eating, well reach over and want to ask a Chinese medicine practitioner to take their pulse. In fact, this time to eat, take the pulse out is not very accurate.

Because you've eaten something in, then say there's, grain qi, and food qi, there's something in the body, then it's possible at this time to put out that it's a slippery vein, a vein that's full of qi and blood.

The pulse will beat very fast when you have just exercised. When you are tired after a day's work, your pulse will beat weakly.

Then of course when you take the pulse the pulse responds to the state of the body in the moment.

So many times the usual problems won't be put out and will be covered up.

That is why Chinese medicine practitioners recommend taking the pulse again on Pingdan, that is, in the morning, at the moment you open your eyes, before you even get out of bed.
