How Plants Improve Your Mental Health
Why Office Air Affects More Than Just Your Lungs
Throughout human history, we have lived closely with plants. Lately, that relationship has quietly reversed. Most office workers now spend more than 90% of their working day indoors, breathing somewhere between 10,800 and 11,000 litres of air. Much of that air is shaped by the room itself: furniture, carpets and electronics all release trace compounds known as Total Volatile Organic Compounds, or TVOC. When motivation and focus dip in a sterile office, the room itself, not the person in it, is often the real cause. Biophilic design offers a quiet, practical answer: bringing living plants back into the spaces where we work, improving air quality and mood at the same time. A green wall, plants arranged vertically across an office wall, is one of the simplest ways to do this.
The Research: How Plants Change The Way We Feel, Think And Work
Stress Reduction
A study published in the Journal of Physiological Anthropology found that office workers using computers often feel restless and disconnected from their surroundings, a state researchers call technostress. When the same workers were given access to potted plants, that discomfort eased. They reported feeling calmer, more soothed and more connected to their environment, simply through the presence of greenery nearby.
Mood And Wellbeing
Time spent near indoor plants brings a measurable lift in mood. The effect reaches the body's stress response directly, calming the sympathetic nervous system that would otherwise stay alert to a perceived threat. Plants achieve this through several senses at once: what we see, hear, touch and smell in a green space. The same pattern appears in forest therapy research, where simply being among trees produces similar physiological calm.
Cognitive Function
The benefits are not limited to stress. A study from the American Society for Horticultural Science found that ornamental plants are linked to greater efficiency at work. Some employees even reported looking to nearby plants for inspiration during difficult tasks, suggesting a genuine link between greenery and creative performance. Our own data, drawn from Market Monthly Overview reports, OxygenX sensors and employee surveys, points to the same conclusion: offices with well placed plants tend to see sharper attention, better memory and stronger problem solving. You can find more on this in our Plant Science Research category.
Getting It Right
These benefits depend on how plants are used, not simply whether they are present. The same American Society for Horticultural Science research found that plant condition, species and personal preference all shape the outcome, which is why a greening concept works best when designed for the specific space rather than applied generically. A few principles matter most:
- Position plants with an eye on natural and artificial light
- Care for them consistently, so they stay healthy
- Group plants together in a dedicated plant island rather than scattering single pots
- Match the number of plants to the size of the office and the number of people in it
- Choose species known for absorbing pollutants and CO2, such as Howea Forsteriana and Strelitzia Nicolai
If designing and maintaining this yourself feels like too much, a personal greening concept handles it for you.
The Takeaway
Office plants are not decoration. The evidence points to a clear role for greenery in mental health, cognitive performance and job satisfaction alike. As more companies bring plants into the workplace, backed by measurable improvements in air quality, the case grows harder to ignore. Healthier air and a livelier space tend to arrive together, and both make it easier for people to do their best work.
Being near potted plants calms the body's stress response and eases the restlessness linked to long hours at a screen. Employees exposed to greenery report feeling calmer and more connected to their surroundings.
Yes. Research from the American Society for Horticultural Science links ornamental plants to greater efficiency, and some employees use nearby plants as a source of inspiration during demanding tasks.
It depends on the size of the office and how many people work there. A greening concept designed for your specific space, rather than a generic plant order, gets this balance right.
Species known for absorbing pollutants and CO2 tend to perform best, such as Howea Forsteriana (Kentia palm) and Strelitzia Nicolai (giant white bird of paradise).
Placement should take natural and artificial light into account. Grouping plants into a dedicated plant island tends to work better than scattering single pots around the room.
Yes, ongoing care matters as much as placement. Plants that are not maintained lose much of their effect on mood, air quality and cognitive benefits, which is why most companies choose a full service greening concept over managing it themselves.
