Blue Monday, Meet Green Monday: The Science Behind How Plants Can Make us Happier

January can be a tough month in the workplace.

All the delayed December tasks rush back onto your agenda, the festive break feels like a distant memory, and the days are still painfully short. Dark mornings and dark evenings have a way of creeping into our mood, whether we notice it or not.

As more and more people are returning to the office, the quality of space in which we spend our days in more important than ever. Our working environment does not just shape how we work. It influences how we feel, both during the day and long after we have logged off. This is where a small change can make a meaningful difference.

A splash of green can have a huge, tangible effect on  how a space feels. Not just visually, but emotionally too.

Plants soften hard lines, bring life into sterile environments and help offices feel calmer and more human.

There is also something deeper at play. Caring for living things encourages us to slow down and notice our surroundings. That sense of care often leads to a stronger feeling of comfort and connection with the space we work in.

Of course, happiness looks different for everyone, and no single solution works for all. But research consistently shows that greenery supports wellbeing in subtle, meaningful ways. From lifting mood to making everyday spaces feel more welcoming, plants have an important role to play, especially during the darker months of the year.

Below, we take a look at some of the specific science of how plants help us remain healthier and happier in our places of work.

Scientific research suggests that plants influence wellbeing through a mix of physical, psychological and behavioural effects. These changes are often subtle, but they add up, particularly in indoor working environments. It is estimated that we spend about one third of our lives in work, taken with a typical hybrid working model, we could reasonably assume that people typically spend about one fifth of their life in their office building…So any way that it can be elevated to elevate you, is incredibly valuable.

Here are a few of the key ways in which plants can contribute to our happiness.

A Healthier Environment Is a Happier One

First of all, there are the physical health benefits of bringing plants into a space. Multiple studies suggest that plants can help improve indoor air quality, contributing to environments that feel fresher and more comfortable.

Research also indicates that better air quality, combined with the psychological benefits plants provide, can support faster patient recovery times in hospital settings. In workplaces, these same effects have been linked to fewer sick days and a reduction in symptoms associated with “sick building syndrome”. This term refers to a range of issues caused by chemicals released in newly built offices, including dry eyes, headaches, and throat irritation. While these symptoms may seem minor, over time they can significantly affect focus, energy levels, and mood.

A healthier physical environment supports a more positive emotional one. When people feel comfortable, they are better able to concentrate and engage with their work.

Greenery Supports Mood and Emotional Wellbeing

The presence of plants is consistently linked with improved mood and reduced feelings of stress and fatigue. Greenery has a way of softening spaces psychologically, making them feel more supportive and less demanding. This can be seen in the work of

This matters in offices, where emotional wellbeing and productivity are closely connected. Even relatively small amounts of greenery have been shown to make a difference, which is why thoughtful planting often has more impact than large, unmanaged displays.

Natural Elements Help Restore Focus and Mental Clarity

Plants also support cognitive function. At a time of year when refocussing your mind, is the focus of your work, this can have a huge effect.

According to Kaplan and Kaplans study of Attention Restoration Theory, natural elements allow the brain to recover better from mental fatigue. Unlike screens or artificial stimuli, plants engage our attention gently, giving our minds space to reset.

This can lead to clearer thinking, improved concentration and reduced feelings of overwhelm. In a busy office, that mental clarity can quietly transform how the working day feels.

Beyond passive benefits, plants invite interaction, and engender a level of care and respect for our environment. According to Edward Wilsons landmark book The Biophilia Hypothesis, plants also help to build a sense of responsibility for our environment. We feel that we, as biological creatures, feel an innate desire to interact with the nature around us.

Looking after a plant introduces small routines and moments of responsibility. Watering, noticing new growth or simply checking in on a living thing can provide a sense of progress and purpose.

Research into gardening and plant care links these micro moments with improved mental wellbeing, including reduced anxiety and increased feelings of self worth. During slower or more challenging periods of the year, these small interactions can be quietly uplifting.

When combined, these effects reinforce one another. Improved comfort supports focus. Better focus supports mood. A calmer environment encourages care and connection.

Buying plants for the first time can feel intimidating. Nobody wants to feel responsible for a struggling plant tucked away in the corner of the office. If you would like to learn more about how to get started, head over to our guide for first time plant buyers.

These concerns are completely normal and are some of the most common reasons people delay introducing plants at work. The good news is that with the right choices, office planting does not have to be difficult or high maintenance.

Bringing plants into your office does not need to be complicated, risky or expensive. With thoughtful choices, even first time buyers can create greener, calmer spaces that support wellbeing over time.

If the new year is about fresh starts and small positive changes, office plants are a wonderful place to begin. Start small, choose well and let the plants do what they do best.
