Effects of Lom-Pa-Kang Steam Inhalation on heart rate variability in people with stress
Keywords:Lom-Pa-Kang Steam Inhalation, stress, heart rate variability, steam inhalation
Stress is one of the factors that cause imbalances in the autonomic nervous system. The purpose of this research was to study the effects of Lom-Pa-Kang Steam Inhalation (LPKSI) on the autonomic nervous system function in stressful conditions by measuring heart rate variability among participants with moderate to severe stress levels. The 60 participants were divided into two groups of 30 people, consisting of control and LPKSI groups. The participants in each group received 30-minute of treatments combined with stress stimulation by using mental arithmetic tasks. The heart rate variability was measured and compared during the period of pre-treatment, immediately after treatment, and after 10 minutes of treatment. The study found that after the participants inhaled LPKSI, the low frequency (LF) value decreased and significantly different from the control group (p-value < 0.05). In addition, the low frequency/high frequency ratio (LF/HF ratio) decreased immediately after treatment and 10 minutes after the treatment group (p-value < 0.05). However, no difference was found in LF value and LF/HF ratio between immediate results and 10 minutes after treatment (p-value > 0.05). This study demonstrated that LPKSI was effective in altering the heart rate variability of the participants under stressful conditions. It decreased the activity of the sympathetic nervous system, and the autonomic nervous system was involved in stimulating the heart to beat faster when the body is stressed or excited.
