Medical effects of the Ion House *1

*1 The Ion House was used to conduct this experiment. The Medical Ion Mini will produce a similar result as it has the same negative ion generation method as the now discontinued Ion House.

Test result by Dr. Watabe, Assistant Professor of Hokkaido University Hospital *2

*2 Currently Professor of Aomori University of Health and Welfare

This experiment was conducted in cooperation with Dr. Ichiro Watabe, Assistant Professor of Hokkaido University Hospital Rehabilitation Department.

Conclusion
Tension of the sympathetic nervous system eases. Stress is endocrinologically/immunology alleviated.

Result
No. Test Measured item The result shows Test result
1 Tension of the sympathetic nervous system Finger temperature change by cold water The recovery speed of the finger temperature, which goes down by cold water, shows the tension of the sympathetic nervous system. The finger temperature recovers quickly, so the tension of the sympathetic nervous system is alleviated.
2 Endocrinological test (Blood test) PT value Numerical value which shows the hemostatic time The lower value shows a higher hemostatic capability.
Cortisol value Numerical value which shows the stress hormone balance The lower value shows less stress.
3 Immunological test (Blood test) Number of NK cells The number of cells which kill cells infected with bacteria and cancer cells. They decrease as stress is alleviated. It is thought that immunological stress is alleviated as the number decreases.

Conducted in Mar 2003

Data 1: Cold water test
Fig.1 shows the finger temperature, which goes down by cold water, recovers quickly. It is thought that the tension of the sympathetic nervous system is alleviated.

Test procedures
8 healthy persons, who are 21-24 years old, participated in this test. It was conducted at 25C/50% in a temperature/humidity-controlled room. The finger temperature of the left hand was measured after immersing in 15C cold water for 3 minutes with and without negative ions. It was also measured after doing a simple calculation, reciting given numbers in the reverse order and breathing deeply.


Data2: PT value, Cortisol value, Number of NK cells
Measured value Without the Ion House With the Ion House p-value
PT value 11.26±0.378 10.9±0.568 0.001
Cortisol value (4-18) micro-g/dl 14.28±4.774 10.93±3.661 0.057
Number of NK cells (1) NK(CD16)cell 19.19±9.371 13.13±3.712 0.019
Number of NK cells (2) 16+56+ 16.61±8.112 11.35±3.573 0.015

*1 n=8
*2 Generally, it is statistically thought to be significant when the p-value is below 0.05.
