We explore how thoughtful design can create spaces that not only look good but also make us feel good. Join us as we uncover the science behind the design elements that shape our mental health.

Interior design is more than just creating visually pleasing spaces. It's about shaping the environment to support our mental and emotional well-being.

Principles of Interior Design

The principles of interior design can be leveraged to create spaces that promote relaxation, stimulate creativity, or foster social interaction. The choice of colours, materials, and layout can all have a significant impact on our mood and behaviour.

Organisation & Design Choices

For instance, a cluttered room can induce feelings of stress and anxiety. On the other hand, a well-organised space can promote a sense of calm and control. Similarly, the use of natural elements in design, known as biophilic design, can reduce stress and enhance mood.

Functional Space

Understanding the psychological impact of interior design can empower us to make informed decisions. It allows us to create spaces that not only meet our functional needs but also support our mental health.

Colours play a crucial role in shaping our emotional responses. They can evoke a wide range of emotions, from calm and relaxation to excitement and energy.

Colours and Meanings

Consider the colour blue, often associated with tranquillity and peace. Incorporating shades of blue in a living space can create a serene environment, conducive to relaxation and rest. On the other hand, vibrant colours like red or orange stimulate activity and conversation, perfect for social spaces.

Psychology of Colour

The psychology of colour also applies to creating spaces for specific purposes. For instance, green has associations with nature and growth. It can feature in a home office to promote concentration and productivity. Meanwhile, a bedroom might benefit from a soothing lavender hue, promoting restful sleep.

Personalisation of Colours

However, it's essential to remember that colour perception can be subjective, influenced by personal experiences and cultural contexts. Therefore, it's crucial to consider individual preferences and reactions when choosing colour schemes. By doing so, we can create spaces that resonate with our emotions and contribute positively to our mental health.

Natural Light: The Serotonin Connection

Using lighting to change interior design

Natural light is a vital element in interior design, with profound effects on our mental health. It influences our mood, sleep patterns, and overall well-being. Exposure to natural light during the day helps regulate our body's internal clock, or circadian rhythm.

What is a Circadian Rhythm?

This rhythm affects our sleep-wake cycle, hormone release, and other bodily functions. When our circadian rhythm is in sync, we're more likely to have a good night's sleep and wake up feeling refreshed.

The Power of Light

Moreover, natural light stimulates the production of serotonin, a hormone that boosts mood, calms us and focuses us. Lack of natural light, on the other hand, can lead to lower serotonin levels. This can potentially contribute to feelings of depression or anxiety.

Bring Light Into Your Interior

Therefore, incorporating ample natural light in our living spaces can enhance our mental health. You can achieve this through thoughtful window placement, use of light-reflecting colours, and careful selection of window treatments. By doing so, we can create a living environment that promotes happiness, productivity, and a sense of well-being.

Clutter and Chaos: The Stress Nexus

The state of our living environment can significantly impact our mental health. A cluttered, disorganised space can contribute to feelings of stress and anxiety.

Stress and Reduced Productivity

Research suggests that clutter overloads our senses, making us feel overwhelmed. It can also make it more difficult to relax, both physically and mentally. Furthermore, clutter can hinder productivity by distracting us and making it harder to focus on tasks.


By maintaining a clean, organised living space, we can reduce stress and create a more peaceful home. This involves regular decluttering, efficient storage solutions, and mindful purchasing habits. Through these practices, we can create a serene space that promotes mental well-being.

It's hard to overstate the importance of personal space and privacy in residential design. Having a private sanctuary where one can retreat and recharge is crucial for mental health.

Benefits of Personal Space

Incorporating elements that reflect personal tastes and values can enhance the sense of ownership and comfort in these spaces. By creating a personal sanctuary, we can foster a sense of well-being and peace in our homes.

Biophilic Design: Nature's Embrace in Urban Dwellings

Biophilic design

Biophilic design principles are gaining traction in the world of interior design. This approach seeks to connect occupants with nature, even in the most urban of settings.

Reducing Stress

Incorporating elements of nature into our living spaces can have profound effects on our mental health. Research shows that exposure to natural elements can reduce stress, enhance mood, and improve cognitive function.

Natural Materials

We can achieve this through the use of natural materials, the inclusion of plants, feathers, and the creation of views to the outside world. Even the use of nature-inspired patterns and colours can evoke a sense of calm and well-being.

Using Feathers

The feathers we use on our lights shades and chandeliers bring another natural element into the home. The way our shades seem to float in mid air takes our gaze upwards and connects us to the animal kingdom. In particular, to the idea of birds in flight.

Biophilic design is not just about aesthetics. It's about creating living spaces that nourish the mind and soul, promoting a healthier and happier life.

Ergonomics plays a crucial role in interior design, directly impacting our physical comfort and, consequently, our mental health. The design and arrangement of furniture can either contribute to or alleviate physical strain and fatigue.

Improving Your Daily Life

In essence, a well-designed, ergonomic space can enhance our overall well-being. It allows us to perform daily tasks with ease. Contributing to a sense of satisfaction and peace in our living environment.

Scent and Sensibility: Olfactory Influences on Emotion

The olfactory elements of a space, often overlooked, can significantly influence our emotional states. Certain scents can trigger memories, evoke emotions, and even alter our mood.

The Power of Smell

For instance, the scent of lavender can induce relaxation, while citrus fragrances can energise and uplift. You can Incorporate these elements into interior design, through candles, essential oils, or even certain plants. This creates a more emotionally balanced environment.

Acoustics and Soundscapes: The Auditory Aesthetics of Peace

The soundscape of a space, much like its visual and olfactory elements, can significantly impact our mental state. Noise pollution, for instance, can lead to increased stress levels and cognitive fatigue.

The Use of Sound

Using nice sounds, such as soft music or the gentle trickle of a water, can help relaxation and mental well-being. Furthermore, the use of sound-absorbing materials in interior design can help create a quieter, more peaceful environment.

Creating Mindfulness

In essence, mindful consideration of acoustics and soundscapes in interior design can contribute to your space. Creating serene spaces that promote mental health.

Healing Architecture: Therapeutic Environmental Design

Use of Building Materials

For instance, the use of natural materials, access to outdoor views can all contribute to a sense of calm and well-being. Similarly, the design of spaces that promote social interaction can help mitigate feelings of isolation and loneliness.

Holistic Approach
