This study aimed to observe the effects of head massage on electromyography (EMG) biofeedback, blood pressure and heart rates in 16 volunteers who worked as massage therapists. The participants were selected using the purposive sampling from those who were 30-50 years old, had no pain in the back and neck and could participate until the end of the project. On average, the participants’ age, weight and height were 40.5 ± 8.91 years , 58.4 ± 8.87 kilograms, and 157.3 ± 3.56 centimeters, respectively; and they worked 32.2 ± 2.74 hours per week and had 25.8 ± 21.83 months of work experience. Each of the subjects received Indian head massage (Shirobhyanga) for 60 minutes, including head massage and acupressure in the supine position for 30 minutes and head-neck-back massage as well as acupressure in the prone position for 30 minutes. Data on EMG biofeedback, blood pressure and heart rates were recorded before, during (30^th minute) and after massage (60^th minute), and were then analyzed using the one-way analysis of variance for the data on repeated measurements. The significance level was set at 0.05. Results showed that 60-minute Indian head massage could significantly reduce the levels of EMG biofeedback heart rate and systolic blood pressure (p = 0.000), but made no change in diastolic blood pressure (p = 0.507). Thus, Indian head massage can relax the body and mind.
