Inhibitory Effects of Far-Infrared Ray-Emitting Belts on Primary Dysmenorrhea

<table>The average abdominal temperatures before and after treatment. Expression values are the mean and standard deviation, and the statistical difference was analyzed by Wilcoxon signed-rank test. Double asterisk mean that this group was highly significantly different from control group (<svg height="11.375" id="M6" style="vertical-align:-0.1638pt" version="1.1" viewbox="0 0 58.712502 11.375" width="58.712502" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink">
