How the Colour of the Bedroom Affects Sleep

The quality and quantity of sleep were linked by the Harvard Medical School to decision-making skills, long and short-term health conditions, memory, and immunity. With so much of our wellbeing at stake, it is important to create environments that are conducive to having a good night’s rest.

While there are many external conditions that affect the quantity and quality of sleep – such as temperature, light, and noise – one surprising factor that people are now beginning to consider is the colour of the bedroom.

As it turns out, researchers have found that certain colours of bedroom walls are more beneficial to sleep. Lifehacker relayed that specific hues have corresponding effects that could contribute to a better quality of rest. Although there is no definite causality, it certainly doesn’t hurt to whip out your paint brushes and rollers and start painting your bedroom.


The study found that 58 percent of British homeowners with blue bedroom walls report regularly waking up feeling happy. This positive emotion is no surprise, seeing as this group of respondents had the highest amount of time sleeping, at an average of seven hours and 52 minutes of sleep every night.

In relation to this observation, Leesa pointed out that it might be due to the association of blue with images of the sky and water, as well as the abstract ideas of trustworthiness and stability. Lighter hues, such as sky blue or cerulean, are known to evoke feelings of tranquility. On the other hand, warmer blues like periwinkle or ultramarine, can promote a good mood.

Those who slept in bedrooms with yellow walls clocked in an average of seven hours and 40 minutes of sleep per night, coming in at second place. The colour encapsulates sunshine, smiley faces, caution lights, and rain boots. It can also evoke feelings of cheerfulness and warmth.

Because it is the same colour as streetlights and reflects a lot of light, some shades are a little too attention-grabbing and tiring for the eyes. Lushome recommends using lighter, more faded shades for decorating an entire room, with bolder yellow hues to be limited to a single accent wall or focal point.

In contrast, green is widely considered as the most relaxing colour for the eye to gaze at. Ranking at third overall, sleepers in green rooms had an average of seven hours and 36 minutes of sleep per evening and reported feeling ‘upbeat and positive’ in the mornings.

Combining the benefits of blue and yellow, green is associated with ideas of the outdoors, freshness, nature, money, and agreement. It is also used to communicate ideas of new beginnings and wholesomeness.

Lighter hues tend to feel more peaceful, while darker and more bluish greens are more complex and bold. The Verdure colour palette, which was explored in a previous blog post here on Moretti Interior Design, uses celery greens, herbal-tea hues to symbolize health, abundance, and vitality.
