This study was conducted to analyze the effects of a horticultural activity program on heart rate variability (HRV) in white-collar workers. The subjects enrolled in the program all worked in automotive manufacturing. Forty white-collar workers were randomly selected; 15 workers were assigned to the case group and 25 workers were assigned to the control group. The workers’ attitude toward plants and their HRV was measured before and after an 8-session horticultural activity program. Multivariate regression analysis was performed, adjusting for factors such as age, marital status, house type, job grade, monthly income, work time, drinking, smoking habit, and level of exercise. There was no statistically significant change in the worker’s attitude toward plants. However, standard deviation of NN interval (SDNN), very low frequency (VLF) values of HRV in the case group were significantly increased compared to the control group. SDNN decreases when there is discordance in the autonomic nervous system, and the VLF value isrelated to the renin-angiotensin system. These values decrease with increasing stress.
