Autonomic nervous system, cortisol response influenced by horticultural activities
A study examined how horticultural activities affect stress relief for patients who are mentally challenged. Two experiments conducted at a rehabilitation center and a residential home in South Korea measured heart rate variation and cortisol levels of mentally challenged adults. The researcher concluded that indoor horticultural activities have an effect on the subjects’ stress relief. Participation in planting activities resulted in the greatest positive influence on subjects’ autonomic nervous system responses.
