The spaces we live in do more than just shelter us, they can also influence how we feel, think, and function.

Interior design experts say design elements from the colours on our walls to the amount of natural light, the layout, textures, and even the scent of a room can have a profound impact on our emotional wellbeing.

An ever-increasing interest in the psychology of our physical spaces has revealed for example that cluttered, poorly lit, or overly sterile environments can heighten stress and anxiety, while warm tones, thoughtful design, and personal touches can foster calm, creativity, and connection.

Carlisle Homes interior designer Jessica Hodges says a well-designed home not only considers functionality but also the owners' emotional wellbeing.

"The physical space in your home has a profound impact on your mood and emotional wellbeing. Whether you're entertaining family, working from home, or winding down on the couch, a thoughtfully designed home can lift your spirits and support your lifestyle," she says.

Melissa Penfold, the author of a new interior design book Natural Living by Design agrees.

"Our surroundings have a profound influence on how we feel. A well-designed home doesn't just look beautiful - it lifts the spirits, supports mental clarity, and enhances daily life," Ms Penfold says.

"Our homes are more than just places we live, they're powerful tools for supporting our mental and physical wellbeing.

"When a space has flow, natural light, and order, it gives us clarity. When it's chaotic or poorly lit, it can chip away at our mood. Good design creates good moods, it's that simple," she says.

Natural Light

Natural light is one of the biggest mood boosters," says Ms Hodges.

"Clever window placement, such as picture windows at stair landings or behind kitchen splashbacks, floods your home with sunlight, creating a bright, welcoming atmosphere," she says.

"Orientation matters too. Living areas that face north or northeast are ideal for capturing all-daylight and warmth, making your home feel alive and energising," she adds

Insulation

Letting in natural light is not only a mood booster but it can also help keep heating costs down in winter.

EB Interiors director Emma Buchan says a well-insulated home is also critical to increasing your comfort and wellbeing at home.

"Good insulation is key... A nice, insulated home will help it to feel cosy and therefore boost your mood," she says.

"Also, the use of soft furnishings can be helpful in insulating a room. Lined curtains and a good quality wool carpet with decent underlay, for example, not only helps for warmth, but also creates a great sound absorber," Ms Buchan says.

Hodges adds that textures can also make a home feel more inviting and increase your mood even when its cold and dreary outside.

"Texture plays a key role in how a space feels. A base of timber floors and stone-look benchtops adds natural warmth, while soft elements like linen curtains, boucle cushions, and textured throw rugs create a sensory cocoon," Ms Hodges explains.

Declutter

"Calming spaces are also clean and uncluttered," Ms Hodges says.

"Thoughtful storage solutions, like walk-in robes, a well-organised laundry, and a butler's pantry, keep everyday mess out of sight. These hidden zones allow your living areas to stay open and tidy, which promotes a sense of calm and control, especially when guests arrive or during a busy work-from-home week."

Colour

Buchan advises choosing colours that make you feel calm and positive rather than being a slave to trends.

"Select tones and colours that you are drawn to and that suit the environment," she says.

"If you are in a dark and moody environment, sometimes it is better to lean into this, rather than trying to make it bright and light, as this can sometimes end up looking drab.

"On the other hand, if you are drawn to colour, trust in that, you will always like it. If you feel like you're more tonal, then listen to that. No matter what is on trend at any time, trust your own taste."

Meanwhile, much research has been done that shows the emotional impact of certain colours.

"We know mood can be lifted with colour. Greens are universally calming, linking us to nature, while deeper hues like navy or forest green bring a sense of tranquillity and security," Ms Hodges explains.

"For a lighter touch, soft earthy tones like sage, warm greys, or muted sand help create a relaxed, restorative space."

Natural Flow

Interior design experts all agree that a home that promotes a natural, airy flow also promotes a feeling of calm

"Flow is key," says Ms Penfold.

"An open-plan layout promotes ease and generosity. When rooms feel connected, they're calmer. You should be able to move through your home with grace and lightness.

Buchan agrees.

Make sure each space flows well into the next, with no sharp right angles, where possible to walk around or pointed corners," she says.

Bring Nature Indoors

Research shows that being exposed to nature and green spaces lowers cortisol levels and activates the parasympathetic nervous system, helping us feel calmer.

It is also linked to lower rates of depression and is known to enhance focus, creativity and memory.

"Nature calms the nervous system and we all need more of that," says Ms Penfold.

"Whether it's a view of trees, a pot of greenery, or materials like stone, linen or timber, nature inside has a calming, healing effect.

"Indoor plants also clean the air and reconnect us to something larger," she says.

Meanwhile, Ms Hodges says even a garden view can improve your mood.

"Indoor greenery, whether real or artificial, adds life and depth. Even a view of a garden or courtyard through large windows can enhance relaxation and mental clarity," she says.

Listen to your instincts

Penfold adds that it is critical to listen to what makes you feel happy and calm when designing, decorating or renovating your home.

"Design to please your senses. Let in air and light. Choose colours that make you exhale. Fill your rooms with texture, quietness, and beauty.

"A well-considered home can be a daily source of comfort, energy and joy. The best spaces don't just shelter us, they restore us," she says.
