multi-sensory wellbeing interiors

How to use light, sound, scent and texture in multisensory Biophilic design for wellbeing benefits

What is wellbeing interior design? 

Wellbeing interiors are simply indoor spaces that have been maximized for human health and wellness. These may or may not include consideration for sustainability as the focus here is primarily on People rather than Planet. The role of human senses is crucial in this context, as a fundamentally multisensory approach to design can enhance the overall well-being of occupants by considering a broader spectrum of human perception, including light, air, sound, and materials selection. Multisensory design is essential in creating meaningful experiences that engage users’ senses, impacting mood, behavior, and well-being.

It’s a subtle distinction and by no means one that suggests mutually exclusive concepts, in fact we would argue that the best examples manage to marry both, bridging both worlds, respecting the environment whilst also promoting enhanced health for occupants of the space.

Wellbeing design considers light, air, sound and materials selection. This is often delivered by a Wellbeing Champion either independently or as a consultant on a wider project team.

What is biophilic design?

Biophilic design combines elements of nature, health and sustainability in interiors and architecture.

Far more than just landscaping, in its finest examples, it maintains a strong visual connection between indoor and outdoor worlds through the careful selection of colours, materials, patterns, shapes and, yes, both living plants and non-living representations of nature.

Our ‘tools’ in this sense include indoor planters and mini gardens, living walls, flooring, wall decor, acoustic panels, natural artworks, furniture fabrics, even eco cleaning policies, aromatherapy, soundscapes.

Natural light in healthy indoor environments

Lighting in a home office environment is important not just for ensuring a respectable image on a Zoom call but also for its role on our mental wellbeing. Natural light is crucial for maintaining consistent circadian rhythms, promoting physical and mental health, and contributing to a healthy multisensory workspace. Digital design plays a significant role in creating multisensory workspaces that incorporate non-visual sensory aspects, such as smell, taste, and touch, to enhance overall perception and experience. Considering a broader spectrum of sensory perceptions, it may not be the first thing we think of in relation to Biophilic design and healthy indoor environments but it is a valuable component in any wellbeing interiors project.

In a workplace wellness strategy, both for home and commercial spaces, daylight exposure is key for well-being.

First up, it’s always a good idea to get a few minutes of direct natural sunlight within the first 30 minutes or so of waking in order to help regulate your circadian rhythm - use a smart light system that recreates that same spectrum of colour for you indoors during the winter months, these lights can also be used to replicate sunlight as your alarm clock all year round, assuming dogs, cats and kids do not get there first!

Similarly, when working from home place your desk set-up near a window to give you as much natural daylight during your work day as possible. When you need supplemental lighting, again a smart light system will allow you to program the colour frequency from blue-white in the morning to amber in the evening, easing you into the day and winding you down steadily at night.

In the evenings one should avoid exposure to intense sources of blue-white light. Halogen ceiling lights will struggle to create the right atmosphere mornings and evenings above all, so you’ll want to switch to a combination of standing lamps and task lighting (e.g. desk lamp) to give more flexibility.

Get this wrong and it can severely affect quality of sleep - we may even be able to fall asleep as usual but there will be less REM sleep and therefore less mental recuperation taking place during the night. Those with sleep monitors on their wrists or fingers should be able to produce their own data to verify this for themselves.

Clearly all screens, be they from a TV, computer or smartphone are possible sources of this same sleep-disrupting light, so ensure there is a program such as f.lux on your computer or just the TV brightness later in the evening - better yet allow yourself a minimum of one hour of screen-free time before bed.

In a family or work scenario where compromises need to be made for whatever reason, individually electing to wear a pair of amber-lensed glasses in the evenings does the same job. Again, it’s worth testing this out and monitoring your sleep quality if it is of interest.

Acoustics in wellbeing interiors

A healthy building needs to address acoustics and other sensory features in order to create a healthy indoor environment that does not promote stress, while aiding in concentration and, in a residential context, ensures high quality sleep at night.

Incorporating sensory integration into the design process is crucial for creating a healthy indoor environment, as it considers the impact of various senses on inhabitants and promotes well-being through a multisensory approach.

Sound insulating materials are often integrated into or under flooring tiles, dry wall insulation, decorative wall panels, room dividers, planters, furniture and even wall paint.

Distracting noises in large, open-plan office spaces can have a direct impact on worker wellbeing and leave staff struggling to find a quiet corner in which to do deep work alone.

Equally, a small room with no soft furnishings in, such as a second bedroom converted into a home office, will require either carpet or a rug, furniture and fabrics - basically anything soft to help stop the sound reverberating around the room.

Once an acoustic plan has established an agreeable baseline of background noise, then we can apply acoustic Biophilic design by bringing in subtle nature sounds or other forms of white noise to mask noise from HVAC systems and elevator shafts. This may not be appropriate everywhere but can, for example, be applied in specific areas such as a reception or waiting area, or canteen.

Sounds of trickling water could be a fountain outside, allowing nature sounds from outside to come indoors, acoustic world music, ethnic, or traditional music from around the world especially drumming, those are all evolutionary aligned soundtracks that are likely to promote focus and drive without distracting.

Delos in the US, the company behind the WELL Certification for healthy buildings, amongst other things, recently launched a biophilic sounds and mindfulness app called MindBreaks that offers high-quality 3D audio to help you “Escape, Energize, Rest, Meditate, Focus and Inspire”.

Acoustic sound booths such as these ones we sourced for the HERO food group’s corporate offices in Switzerland can also be integrated into a Biophilia plan by selecting suitable colours for the acoustic fabrics inside, options for models with wood (or veneer) panelling, placing plants around the booths and generally ensuring they integrate smoothly into the overall workplace design.

Finally, music with lyrics can be distracting at least in a language that we understand and there is nothing worse in a workplace context than a playlist that prevents us from doing our best work each day but as a rule, acoustic, traditional and ethnic sounds are going to be especially good at filling the void in a workspace context without demanding too much of your mental focus and attention.

Whether that is a realistic game plan for 8-10 hours a day or not is up to you and your colleagues to decide, perhaps just as we move around a workplace for different tasks, having specific playlists (or indeed a ‘no music’ policy) that match those tasks, might be a sensible solution?

Scent in Biophilic design interiors

So, we mentioned the idea of forest bathing a corollary of Biophilic design in interiors. Forest phytoncides are a particular airborne substance given off by certain species of trees that has been shown in South East Korea to boost the human immune system too.

When combined with what we know about the mental health benefits of spending time in nature, it’s clear that aromatherapy has a role to play in a multi-sensory Biophilic design strategy. This strategy emphasizes the importance of sensory experience, incorporating all five senses: sight, hearing, touch, smell, and even taste to create innovative and memorable environments. Adding layer upon layer of nature-inspired detail in a Biophilic interior concept can significantly enhance the sensory experience.

Invest in a high-quality pine or cypress oil for your home aromatherapy diffuser, perhaps combined with rosemary and peppermint to capture some of the same health benefits of spending time outside in a forest.

Think especially of how this could be done in a home office environment, for example, where a little Biophilic design can go a long way in creating a wellbeing interior geared for productivity and calm. The impact of sound in the workplace environment should also be considered, addressing both its positive and negative effects.

Equally, citrus oils such as bergamot and lemon are especially good for focus, followed by lavender later in the evening to help you wind down when the workday is done.

Texture in healthy interiors for sensory experience

Last but not least, let’s not forget the role of texture and sensory qualities in wellbeing interiors, as designing for all the senses with a carefully chosen natural fabric or finish with just the right amount of tactility can add an additional layer of nature-connectedness to a Biophilic design.

Man-made materials tend to be impossibly perfect compared to nature, so integrating natural materials such as wool, cork, wood and cotton in carefully selected places can invite a tactile interaction with the interiors. Plastic may be cheap and easy to clean but, at least from a Biophilic design perspective, it will never be able to compete with real wood or bamboo say.

We might imagine a decorative cork wall in an office reception for example such as those by Gencork or a textured jute rug by Nanimarquina in a home office inviting the user to spend time barefoot during the day.

Not all of the strategies need to be combined in every wellbeing interior but there is magic in integrating more than one of them as a way to add interest and intrigue…
