Qigong science belongs to the field of traditional Chinese medicine with a long history of several thousands of years. Qigong can improve one's health and dispel one's diseases by adjusting one's breathing, posture and spirit. It has been proved by lots of historical experience that qigong exercise is surely beneficial to health, and that is the reason why qigong science has been so prosperous and spread so widely through centuries. But the mechanism of effect of qigong was not known and in nowadays the flourishing of qigong has been attracting more and more people to study its mechanism of effect and many data and facts have shown that Qigong both from inside and from outside of one's body has great subjective and objective affection. Here is a testing result reporting how qigong effects the brain blood supply.

About the tests:

The testee, male, 67 years old, with over 10 years of exercising qigong, who has no addiction to smoking and drinking and has no any particular hobby. He seldom takes meat and did not take any medicine for cardiovascular diseases in recent years. He does qigong exercise about two hours every day.

Adopted instrument and testing method:

A transistorized bridge-type RG-2B Flowgraph (made in Shanghai Medical Electron Instrument Factory) is used, with oscillating frequency of 75 kg, standard signal resistance of 0.1 and recording rate of 25 mm/s. Room temperature: around 20 C; electrodes were put at bilateral frontal-mastoid and occipital-mastoid points, the man sitting in peace, for observing changes of wave shape and wave scope of brain blood flow.

Testing sequence and results:

The testee received two tests. The first test was made separately before exercising qigong and then 10 minutes after entering qigong state; the second test was made 10 days later, also separately before exercising qigong and then 15 minutes after entering qigong state. We got the results from the two tests that there were no obvious changes in wave shape, but there were great changes in wave scope, as follows:

Changes of wave scope:

state frontal-mastoid point occipital-mastoid point
left right left right

before entering 0.130 0.120 0.100 0.110
Qigong state

10 minutes after 0.140 0.122 0.130 0.123
entering Qigong

before Qigong 0.130 0.130 0.173 0.173

15 min. after 0.136 0.158 0.152 0.182
entering Qigong

The average change value of wave scope:

state frontal-mastoid point occipital-mastoid point
left right left right

before Qigong 0.130 0.125 0.136 0.141

after Qigong 0.138 0.140 0.141 0.152


From above data we can see that the wave scope was obviously increased after entering qigong state, which strongly indicates a dilatation and blood flow increase of the brain vessels and that exercising qigong can improve the brain blood flow, therefore it is helpful for prevention and cure or encephalovascular diseases.

As only a few testings like this have been made, this can be a tentative attempt. Advices from same field will be welcome.
