Abstract：Objective To investigate the interventional effect of regular far-infrared irradiation on excessive proliferation of red blood cells at high altitudes via changes in red blood cell counts and regular far infrared irradiation.Methods After rigorous screening,the subjects were randomly divided into the far-infrared intervention group and control group.Patients with chronic high-altitude diseases were excluded.The intervention group received 50 days of far-infrared radiation at the intensity of 200 W once a day.Before and after interventions,peripheral blood was collected and biochemical analysis was conducted.Self-control and intra-group comparison methods were used for statistical analysis.Results Far infrared irradiation at a wavelength of 3.5～16.0 μm and an intensity above 200 W had no adverse effects on the subjects.The intervention group showed a significant decrease in systolic blood pressure,but an increase in blood oxygen saturation,diastolic blood pressure,and heart rate(Z=-3.184,-2.919,t=3.200,3.983;P＜0.001,=0.004,0.007,0.002).After interventions,the red blood cell count in the control group was increased(P=0.001).The results of intra-group comparison showed that there were statistically significant differences in hemoglobin,red blood cell counts,and HCT between the two groups before interventions(U=74.000,49.000,79.500,P=0.002,＜0.001,=0.004)and after interventions(Hgroup=10.010,13.370,9.381,P=0.002,＜0.001,0.002).Conclusion Whole-body far-infrared irradiation or local irradiation for more than 30 minutes per day for 50 days can effectively curb the increase in red blood cells caused by high-altitude exposure,suggesting that regular far-infrared radiation can effectively alleviate excessive proliferation of red blood cells caused by chronic diseases related to high altitudes.
