Abstract
It is an easy way of thinking that people-plant relationships (PPR) exhibit the activation of a past long-term memory and future hope to live for.
Therefore, we decided to classify ways of thinking of people-plant relationships which help prevent dementia progress in the present, the past and the future.
We made a schematic view in current emotion and past memory and future expectation about the effectiveness of PPR for elderly people with dementia.
Furthermore, we decided to inspect the relaxation and cognitive impairment reduction effects of horticultural therapy activities by examining influence on autonomic nervous system (ANS). A spectral electrocardiogram (ECG) analysis (heart rate variance: HRV analysis) was performed using software, Mem Calc/Tarawa system (GMS, Japan), which is a non-invasive, real-time analysis system.
The low-frequency (LF: 0.04-0.15 Hz) component reflects sympathetic and parasympathetic modulation, whereas the high-frequency (HF: 0.15-0.4 Hz) component mainly reflects para-sympathetic modulation.
The LF/HF ratio represents a measure of sympathetic/para-sympathetic balance.
Electrocardiogram (ECG) was measured using a continuous wave frequency spectrum analysis.
Results indicated that the sympathetic nervous system (SNS) during a horticultural therapeutic garden visit has been retracted, the parasympathetic nervous system (PNS) was confirmed to be enhanced.
The benefits of horticultural activities in the garden have been demonstrated to have overall positive effects on the emotional health of people with severe dementia.
