A landscaper's advice for making your backyard more peaceful - and the science behind it

Having a tranquil natural retreat at home can be important for mental well-being. A 2017 study conducted by Brighton and Sussex Medical School in England suggested that nature sounds could positively alter physiological functions.

Researchers analyzed functional magnetic resonance imaging and the heart rates of 17 participants to study the link between nature sounds and bodily reactions. They found that natural soundscapes dimmed the sympathetic nervous system, which is responsible for the "fight or flight" instinct, and strengthened the parasympathetic nervous system, which helps evoke feelings of rest and relaxation.

If there were any seeds of doubt keeping you from revamping your outdoor space, consider this a sign to sow seeds of inspiration instead.

Incorporate natural sounds and elements to inspire peace in your outdoor space

There are several ways to enhance an outdoor area to make you feel more serene. Ryan Trudell, the vice president of landscape architecture at Creative Environments, told Insider that one of the best tactics is to incorporate water. "Water elements are the typically desired method to achieve tranquility in the garden," Trudell said.

Whether it comes from waterfalls or small bubbling fountains, water adds beautiful auditory and visual features that can greatly affect the spirit of a space. Some research suggests that listening to water can induce a meditative state.

Using shade also helps create a calming, intimate space with minimal money and effort. If you have naturally shaded areas from tree canopies, Trudell recommended placing a hammock or a daybed underneath.

Planting a sensory garden, which stimulates the senses through plants and other materials, is another wonderful way to relax. If you want to stimulate your senses of sound and smell, fill your sensory garden with aromatic plants that make calming noises when the wind passes through them. You can do this with a food garden as well.

"Countless reports show connection to nature is a leading method to reduce stress," Trudell told Insider. Sensory gardens in particular can alleviate stress by encouraging you to slow down and enjoy your surroundings.

Incorporating more vegetation in your space could also lure interesting wildlife. Trudell suggested planting a butterfly garden designed to attract the vibrant insects. You could also plant a few tubular flowers to attract hummingbirds if you don't have space for a full garden.

Furnish your outdoor area in a way that fosters collective comfort and serenity

Another important technique for creating a soothing outdoor area is having comfortable furniture to make it more inviting. "Gathering in comfortable furniture is a critical feature in enjoying life outdoors," Trudell said.

Creating a setting that you and others want to be a part of can enhance your overall well-being. Research led by the University of York suggests that relishing nature in groups can lead to more mental-health gains than doing so alone.

Trudell said you could incorporate designated nooks and intimate spaces around your yard by building a charming shed, adding a potting bench, setting up a reading garden, or arranging art pieces in a particular spot - whatever helps strengthen your connection to nature.

"For peaceful or tranquil gardens, I find that more whimsical or abstract pieces are a great fit," Trudell told Insider. If whimsy isn't your forte, find pieces that evoke equanimity for you.

Create indoor-outdoor cohesion with your decor

Trudell also recommended incorporating patterns, materials, and colors featured inside your home. This generates a synergy between your indoor and outdoor lodgings. "Bringing in those materials that unify the sites in and of itself kind of creates a peaceful harmony to design, because everything feels cohesive," he said.

You can achieve a harmonious effect through motion-driven outdoor equipment, such as hanging furniture or a swing, Trudell said, adding that having the ability to sit and sway enables you to composedly move and breathe in that space.

To continue enjoying the outdoors throughout the evening, install dim lighting that creates an intimate, relaxed nighttime ambiance. Trudell recommended stringing bistro lights or installing a fireplace or pit to set a warm, solacing atmosphere.
