Also, in terms of health, the stress levels of the experiment group tended to be significantly lower than the control group. The depression index analysis showed the control group had a much higher level of depression than the experiment group with considerably significant disparity. The autonomic nervous system analysis revealed the stress index was significantly lower for the experiment group than the control group, and also, in terms of pulse diversity, the experiment group was within the range of normality, whereas the control group was exposed to the influence of chronic stress. The research results showed that urban agriculture activities applied to the elderly stabilizes the sympathetic nerve and activates the parasympathetic nerve to increase the resistance against stress.
