ABSTRACT
INTRODUCTION:
The accumulation of fatigue and stress creates problems, including reductions in quality of life and productivity.OBJECTIVES:
To investigate the effects of a far-infrared heater that heats the feet with ceramic balls on autonomic nervous activity and mood states.METHODS:
This study was performed as a crossover trial. Participants comprised 20 women. On different days, each participant underwent 15â min of foot warming with the far-infrared heater (far-infrared group) or remained seated for 15â min (control group). Autonomic nervous activity (low-frequency component/high-frequency component, high-frequency) and mood states scales (Profile of Mood States Second Edition and Two-Dimensional Mood Scale for Self-monitoring and Self-regulation of Momentary Mood States) during the study intervention were measured and compared between groups.RESULTS:
Low-frequency/high-frequency was significantly higher in the control group 10â min after the start of intervention than at baseline (P = .033). Low-frequency/high-frequency was significantly lower in the far-infrared group than in the control group at 5â min (P = .027), 10â min (P = .011), and 15â min (P = .015). High-frequency was significantly higher in the far-infrared group at 5â min (P = .008), 10â min (P = .004), and 15â min (P = .015) than at baseline. High-frequency 5â min after the start of intervention was significantly higher in the far-infrared group than in the control group (P = .033). POMS2 scores improved significantly more in the far-infrared group than in the control group, including in fatigue-inertia (P = .019), tension-anxiety (P = .025), and total mood disturbance (P = .019). Finally, the far-infrared group showed greater improvements in Two-Dimensional Mood Scale-Short Term scores such as stability (P = .002) and pleasure (P = .013).CONCLUSION:
Using the far-infrared heater to heat the feet with ceramic balls stabilized and improved mood, reduced Fatigue-Inertia and Tension-Anxiety, and alleviated total mood disturbance. Parasympathetic nervous system activation was observed from 5â min after the start of heating, suggesting that short-duration heat stimulation of the feet is effective.Palavras-chave
