Indoor plants and mental health

The average person spends more than 85% of their time indoors. Houseplants are an easy way to bring the outdoors and greenery into your home and workplace. Studies have shown that indoor plants are associated with improved mental health. Here are some specific ways that greenery can help your mental wellbeing:

Reduced stress

Having plants at your home or workplace can help reduce stress. Researchers found that undergraduates who were in a windowless computer lab had lower blood pressure levels when there were plants in the room compared to when there were no plants.

Working on plants can soothe you and lower your stress levels. Researchers asked study participants to re-pot a houseplant and also to do a task on a computer. Participants’ heart rate and blood pressure went up when working on the computer task, but their stress levels went down when they were repotting the plant.

Faster recovery and healing

The presence of indoor plants may help patients heal faster and reduce medication. In a study of 80 patients who had the same type of surgery, researchers found that those in rooms with flowers and plants had shorter hospital stays and needed less painkillers than those who didn’t have greenery in their rooms.

The patients with plants in their room also had lower ratings of anxiety, fatigue, and pain. They had more positive feelings about their hospital rooms.

Improved productivity

Having plants at your workplace is associated with higher productivity, less sick leave, and lower stress levels. Researchers found that having a plant directly in front of you may have a positive effect on your work performance when you are carrying out a creative task.

Less anxiety

Exposure to greenery can improve anxiety symptoms. Researchers studied university students who spent an average of 20 hours a day at home since the Covid-19 pandemic. Those who had indoor plants or a view of outdoor greenery had less anxiety symptoms.

The students said that having indoor plants gave them the feeling that they were away instead of at home. The presence of plants helped them see their homes as places of restoration and rest, which led to better mental health. This was in spite of having to spend more time at home because all their classes were online during the pandemic.

Improved learning environment

Having indoor plants may also help to improve a school’s learning environment. In a junior high school in Taiwan, researchers placed several plants at the back of one eighth grade classroom for one semester. Students in this classroom had significantly fewer hours of absence due to sickness and received less discipline for misbehavior. They also felt more comfortable and friendly compared to students in a classroom with no greenery.
