Plants Improve Your Mental Health
It’s more important than ever to improve your mental health, how do plants do it?
Plants for mental health
Study 1 - Plants reduce Physiological and Psychological signs of stress
In a study published in The Journal of Physiological Anthropology in 2015, found that active interaction with indoor plants can reduce physiological and psychological stress compared with mental work.
The study comprised of one group of participants working on a computer task while a second group repotted indoor plants. After the groups completed their tasks, the assignments switched.
The researchers found that the subjects felt more comfortable and relaxed after the task interacting with plants rather than the computer task. They measured the participants stress response to the tasks at hand and found that the plants helped to reduce heart-rate and blood pressure while the computer task had a negative impact on these factors.
The conclusion of this study determined that “individuals could reduce physiological and psychological stress by interacting with plants”. Showing that if we all just spent a little less time on our screens and a little more time with nature we might be a little more relaxed for it on the whole.
Study 2 - Horticultural therapy in a psychiatric in-patient setting
In-patient mental health services have a duty to constantly seek to improve patient experience and to assist in the development of new skills that can aid recovery. Horticultural therapy can be implemented in an economic, social and environmentally sustainable way to achieve those goals.
The Cavell Centre in Peterborough, UK, is one of the main mental health centres in the east of England. They have implemented a horitculture therapy model to help those who are experiencing an acute detiorioration in their mental health. Their in-patient wards have various way to access plants including:
- plant in your room
- on-ward gardening (individual or in a group)
- on-site garden
- off-site community allotment
- volunteer community gardening
- paid gardening.
They found that their patients report that the project helps and supports the wider in-patient community, and describe pride and a sense of achievement when returning from these groups. Meaningful and purposeful goals are beneficial to all involved, although doing things just for the pleasure of it is an often-understated gain. Social interaction takes place in all the pathways – with services, peers or members of the public. This helps to tackle social isolation and increase social inclusion, contributing to the individual’s recovery.

A survey conducted at four San Francisco Bay Area hospitals in 2010 found that humans generally feel happier and optimistic in surroundings that contain plants. 79% of participants reported feeling more relaxed and calmer than they had felt before, with 19% claiming that they felt “refreshed and stronger” after spending time with nature.
