What You'll Learn

Blue bedroom walls promote sleep
Blue bedroom walls can promote sleep as blue is associated with calmness and relaxation. Blue promotes mental calmness and could help you doze off faster. It is often associated with tranquility, a clear sky, or a calm body of water. Studies have shown that blue is strongly linked to words such as "relaxed", "safe", "satisfied", and "secure". Blue is also said to reduce heart rate and blood pressure.
Research has found that people with blue bedrooms had the longest average sleep per night compared to people with different colored bedrooms. This may be because blue promotes positive emotions and associations. Blue is also considered to be a cool color due to its short wavelength, which people generally prefer for interior spaces.
Blue is also a good choice for bedroom walls as it is a relaxing color that can help you get a good night's rest. It is associated with calmness and serenity and can make you feel safe, relaxed, and calm. Blue is also linked to feelings of trust, stability, and dependability.
However, it is important to note that darker shades of blue can evoke negative feelings such as sadness, loneliness, and defeat. Therefore, when picking a shade of blue, it is recommended to go for lighter colors such as a light blue or a clear blue sky.
While blue is a great color for bedroom walls, other colors such as green, purple, white, and beige can also be good choices as these colors can help you relax and put your mind at rest. Green, for instance, is associated with hope, serenity, calmness, and inner peace. White is also a good choice as it is associated with positive words such as peace, secure, safe, and relaxed.

Green is relaxing and evokes positive feelings
While personal colour preferences vary, research suggests that certain colours, such as blue and green, tend to evoke more positive emotions and associations. Green, in particular, is relaxing and has a positive impact on our minds and bodies.
Green is considered a cool colour due to its short wavelength. It is often associated with nature and is linked to feelings of comfort, peace, spaciousness, hope, serenity, calmness, and inner peace. Research has shown that green may help alleviate anxiety in high-stress situations. In one study, volunteers who wore green-coloured glasses for 15 minutes before a dental procedure experienced less anxiety, stress, and pain compared to a control group wearing clear glasses.
The colour green can also promote positive feelings of happiness and comfort. Its calming effects may help reduce stress and improve overall well-being, creating a relaxing atmosphere that is conducive to sleep.
Although the ideal sleep environment is dark, incorporating green accents or decor in your bedroom can provide a similar effect. This could include items such as cosy blankets, throw pillows, or other decorative items in soft shades of green. Alternatively, painting an accent wall green can add a calming touch to the room without being overwhelming.
In conclusion, green is a relaxing colour that evokes positive feelings and promotes a sense of calm and peace. Incorporating green into your sleep environment can help create a soothing atmosphere that prepares your mind and body for restful sleep.

Red may negatively affect sleep
While there is limited research on the direct connection between bedroom colors and sleep, some studies suggest that certain colors may promote positive emotions and associations, while others may have a negative impact.
Red is one color that may negatively affect sleep. Red is associated with high energy and can increase brain activity, making it challenging to fall asleep. It can evoke feelings of love, anger, or power, and in some cases, it may also increase blood pressure and heart rate. If your bedroom is painted red, you might feel energized and restless instead of relaxed.
Research has also explored the effects of red light on sleep. While some studies suggest that red light may improve sleep, others indicate that it can lead to increased alertness and arousal levels, negatively impacting sleep onset. Red light has been found to induce sleep in mice at intensities above 10 lux, but it is not yet clear if this applies to humans.
Additionally, the color red in the bedroom can create a stimulating environment that may not be conducive to relaxation. Mentally stimulating colors like red, orange, and bright yellow are generally not recommended for bedrooms as they can make it challenging to wind down and prepare for sleep.
When it comes to optimizing your sleep environment, it is essential to consider your personal preferences and what helps you relax. While blue and green are often recommended for their calming and relaxing effects, the most important factor is choosing a color that promotes calmness and positivity for you.

Mentally stimulating colours are not bedroom-friendly
When it comes to getting a good night's sleep, the colours in your bedroom can play a significant role. While personal preferences vary, certain colours are more likely to create a calming atmosphere and promote positive emotions, making it easier to relax and fall asleep.
Colours like blue and green are often associated with calmness and relaxation. Blue, in particular, has been found to promote mental calmness and can help you fall asleep faster. Green is associated with nature, evoking feelings of comfort, peace, and spaciousness. Cooler colours like purple, white, and beige can also have a calming effect, helping you unwind and prepare for sleep.
On the other hand, mentally stimulating colours like red, orange, and bright yellow are generally not recommended for bedrooms. These colours are associated with increased energy levels and brain activity, which can make it challenging to relax and fall asleep. Red, for example, can increase blood pressure and heart rate, creating a sense of restlessness. Orange and yellow are also stimulating and can create feelings of excitement, which may be counterproductive when trying to wind down for sleep.
While black can create a chic and dramatic aesthetic, it may be too intense for a bedroom. It can make the space feel smaller and more enclosed, potentially leading to feelings of confinement and restlessness. Similarly, purple, especially in its brighter forms, can be too stimulating for a bedroom due to its association with creativity and imagination. Dark brown can also create a gloomy and heavy atmosphere, making it challenging to achieve a restful sleep environment.
When choosing bedroom colours, it's essential to consider your personal preferences and how different shades make you feel. While certain colours are generally more calming, the most important factor is creating a space that promotes relaxation and makes you feel comfortable and relaxed.

Cooler colours help you relax
While there is little research on the direct connection between colour and sleep, it is believed that certain colours can promote calmness and positivity, helping you relax before bed. Cooler colours like blue, green, purple, white, and beige are often recommended for a good night's sleep.
Blue is often associated with calmness and relaxation. A survey found that people with blue bedrooms slept longer on average than those with differently coloured bedrooms. However, darker shades of blue can evoke feelings of sadness and loneliness. Green is another cool colour that is associated with nature and evokes feelings of comfort, peace, spaciousness, hope, and happiness. A recent study found that wearing green-coloured glasses reduced anxiety and stress in volunteers before a dental procedure.
Purple is also considered a relaxing colour, with some suggesting it is a good choice for sleep. While pink is not a cooler colour, soft shades of pink in blankets, throw pillows, or decor items can add a splash of colour to a bedroom without being overwhelming.
It is important to note that colour preferences vary among individuals and can change over time due to life experiences and learning. While the optimal sleep environment is dark, small changes like adding colour can make a big difference in how easily one drifts off.
