The Mental Health Effects of Houseplants

Let’s discuss the mental health effects of houseplants in today’s blog.

There’s something about a houseplant that can just brighten up a room. Adding a little potted plant to your window sill or creating a plant shelf near a window of your home may be an exciting prospect, but can these houseplants actually make you happier? 

You may or may not be surprised to find that house plants can actually have a positive impact on your mental health. Let’s discuss the mental health effects of houseplants in today’s blog.

The Science Behind Houseplants and Mental Health

Back in 2015, a study was published in the Journal of Physiological Anthropology about the impact of houseplants on the mental health of young adults. 24 young adults were studied. 12 were given the task of transplanting an indoor plant; 12 were given a task on the computer. By studying their heart rate variability and blood pressure, the study found a healthy heart rate and decrease in blood pressure from those who worked with the indoor plant. The opposite was true of those with the computer task.1 The 12 taking care of the indoor plant also reported feeling more comfortable and at ease throughout the task.

Both of these tasks took place indoors. So how was the indoor plant task so much more soothing than the computer task? The conclusion was that the interaction with the indoor plant caused a suppression of the sympathetic nervous system, responsible for stress responses, and diastolic blood pressure. This leads to more feelings of calm and happiness.

The Mental Health Benefits of Houseplants

So there has been solid evidence that time spent around houseplants can have an impact on your mental health, and that benefit is a positive one. But what are some of the other benefits of houseplants on your mental health? Here are a few that stand out:

Reduced Stress and Anxiety

An article from Time Magazine entitled “Indoor Plants Have Surprising Health Benefits. Here They Are” referenced the same study that was posted in the Journal of Physiological Anthropology. They also interviewed Melinda Knuth, an assistant professor of horticultural sciences at North Carolina University. 

According to Knuth, “We see a clear connection with the fact that being around plants improves cortisol levels in our body.”2 She states this is because we hold cortisol, the stress hormone, in our saliva, which is decreased around plants. Another study conducted on patients in a hospital waiting room found that their stress was reduced looking at both real plants and photographs of plants or artificial plants.3

Increased Attention

Multiple studies on elementary school students2 have shown that their attention span and concentration is increased when in the presence of plants. In this case, it tends to increase in the presence of real plants rather than artificial plants or pictures of plants. Students in classrooms that have real plants have scored better on tests for selective attention and have generally had more focus in class. With many adults now working from home, this speaks to the benefits of keeping a plant on your desk.

Increased Happiness

We see this in the 2015 study as well as the 2012 study. However, there have been numerous experiments that have proven time and time again the satisfying impact of spending time around some greenery. In a recent 2019 study, it was proven that comfort and positive emotions increased the longer the subjects spent in the presence of plants — especially purple and green plants.4 They’ve even been shown to increase self-esteem.

A Sense of Responsibility

Plants can help you feel more calm, happy, and concentrated. They are also a responsibility. You have to care for houseplants to keep them healthy and vibrant. They need the right amount of sunlight, water, trimming, and so on. While the care is minimal, it can also give you a sense of pride. You are nurturing a life, however small. For those who want to take care of something but don’t feel ready for a pet or in a place to have children, a plant can be a great way to motivate you not to fall into a vegetative depression.

Houseplants have a number of benefits on your mental health. However, of course, they are not meant to be a replacement for therapy or medication management. If you are struggling with your mental health, it’s always best to reach out to a mental health professional to receive treatment. A houseplant can be a supplemental help.
