A symphony for our senses

Humans traditionally recognize five senses, but we actually possess many more. These senses work together to interpret the environment, essential for survival. Modern urban settings can overwhelm our senses, leading to stress. Biophilic design aims to restore sensory balance by incorporating nature, enhancing comfort and overall well-being, much like the harmony of an orchestra.

Introducing the sense orchestra

Consider vision. What do we actually sense with our eyes?

We use our eyes to see shapes, estimate distances, perceive colour, determine brightness, work out which way is up, detect movement, tell us about the direction we are facing, or moving towards, and estimate speed. Changes in brightness and daylength tell us about passing of time and the change of the seasons.

Our eyes are very much our primary sense, but what we see makes more sense if it is confirmed by what we hear, smell, touch and taste.

Our stereophonic hearing helps us to know where we are in relation to the source of the noise. Is it to our left or right, or even behind us? Is it moving towards us or away? And other tiny organs in our ears work in harmony with our eyes to tell us which way is up and how fast we are moving and turning.

Our eyes, nose and mouth working together are critical for telling us whether something is safe to eat, and our tongue is more than just a collection of taste buds – it is full of sensors that inform us about textures and temperatures.

We have sense organs inside our body. They tell us if we have indigestion or when we have an infection, or have sustained damage. Understanding and interpreting our internal senses is called interoception – a new word for me.

Our biggest sense organ is, of course, our skin. It tells us so much about our environment. We detect temperature, texture, hardness, malleability, size, shape and the quality of materials. The hairs on our skin can respond to changes in static electricity and there is no doubt that touch can generate the most intense pleasure.

Composing the piece

Human senses work together to help us to understand our environment, or rather the environment that we spent well over 90% of our existence (maybe as much 99% if you include our immediate hominid ancestors).

Our senses evolved to allow us to survive in a particular environment: open savannah. This environment is characterized by open vistas, undulating terrain, scattered and clustered vegetation and plenty of water. It was quite warm, although there were some seasonal variations. In our ancestral, natural environment, our senses told us about opportunities and threats. However, they need to work in harmony to give us the full picture.

The modern, urban environment is quite a long way from those open plains. Buildings mean that sounds echo around so the direction we hear from is not the same as where we see the source. We bombard some of our senses whilst simultaneously dull others. After all, we cover most of our largest sense organ, most of the time, and deprive ourselves of gaining vital information about our environment.

These confusing, discordant inputs cause stress. We have to make a lot of mental effort to understand what is going on.

Melody and harmony

The practice of biophilic design – bringing a sense of nature into our built environment – is a step towards correcting this sensory discord. It often focuses on the visual sense by incorporating natural views, plants, and natural light, and it is becoming increasingly commonplace in modern design.

However, an aletheic environment brings a new level of comfort and restoration by going even further. The idea is to provide complete, harmonious sensory stimulation that restores the connection our ancestors once had. While it may not be possible in every space (office naturism is probably a step too far for most), we can create restorative environments in our places of leisure and living that allow us to experience this deep reconnection.

The orchestral score

The metaphor with music is a good one. By thoughtfully designing spaces that appeal to all of our senses in an unfiltered way, we can go beyond simply adding plants. We can compose a full symphony, where every input works together to create an experience that is far more than the sum of its parts.
