Thirty healthy male college students (age 22.30 ± 2.26 yrs; height 174.41 ± 5.52 cm; weight 70.74 ± 8.39 kg) participated in this study. Negative magnetic fields group , positive magnetic fields group, or control group were intervened on the insomnia acupuncture points of head in counterbalance order and double blind methods. The same test was administered after 3 days. The measurement device of electroencephalography was used to measure β wave in 30 minutes of intervenient, and the measurement device of Ryodoraku was used to measure Ryodoraku value before and after the intervenient. In electroencephalography β wave data was analyzed every 30 seconds were separated as 1 epoch, and all of 60 epoches. To compare every epoches with the baseline of the first epoch were using paired-sample t test. In Ryodoraku, the difference between pre-test and post-test was tested using paired-sample t test, furthermore, any between-group differences were analyzed with one way AVONA test and subsequently with Dunnett post hoc test. The level of significance was set at p < .05. There were four results. 1. In β wave of C3, negative magnetic fields group appeared significant decline earlier than positive magnetic fields group and control group (NMF group: the 3rd epoch; PMF group: the 10th epoch; control group: the 5th epoch). Additionally, negative magnetic fields group still maintained more significant decline than positive magnetic fields group and control group (β wave was continued to the 60th epoch in NMF group; β wave was continued to 25th epoch in PMF group; β wave was continued to 40th epoch in control group). 2. In β wave of O1, its result was like β wave of C3 in "result 1". 3. In average Ryodoraku value, all of three groups significantly decresed in post-test compared with pre-test(p<. 01). but there was no significant difference between the three groups' interval of pre-test and post-test. 4. In individual Ryodoraku value, interval of pre-test and post-test in spleen Ryodoraku value was significantly higher than control groups after negative magnetic fields group intervenient(p< .05), but positive magnetic fields groups wasn't. Reversely, interval of pre-test and post-test in bladder Ryodoraku value was significantly higher than control groups after positive magnetic fields group intervenient(p< .05), but negative magnetic fields groups wasn't. The other intervals of pre-test and post-test were no significant differences. According to electroencephalography theory, β wave was named brain wave of nervousness. With the increase of β wave, physical and psychic presented nervous status, conversely, they presented relaxing status with decrease of β wave. The primary mechanism of insomnia was emphasized “yin deficiency, yang overactive” in traditional Chinese medicine theory. Positive magnetic fields could make “Bladder Meridian of Foot-Taiyang” incredibly overactive; on the contrary, negative magnetic fields group could make “Spleen Meridian of Foot-Taiyin” extremely promotional. In other words, positive magnetic fields caused yang incredibly overactive that could lead to fade out from sleeping status; however, negative magnetic fields could really supply the failure of yin deficiency. Consequently, the conclusion is that negative magnetic fields could help promoting sleeping.
