What Is The Best Color Light For Sleep?

Did you know that there are specific calming colors for sleep? Light plays an important role in our sleep cycle so it’s important to carefully select the best color light for sleep. Lights that have bright white or light-hued bulbs make it more difficult to fall asleep.

If you often find yourself laying in bed struggling to fall asleep, or waking up in the middle of the night, it might be a good idea to look into what you can do to resolve this issue. Having a good night's sleep is super important for your overall well being.

A simple change in your choice of night light for sleeping can make a huge difference. So why not give it a try? The effect light has on our sleep might be underestimated. However, there have been studies that show that the color of the light you see when you wake up in the middle of the night or before falling asleep has a large impact on your internal biological clock.

So what colour light is best for sleeping and how does light affect our sleep?


Best color lights for sleep


●     Amber light

This light is an appropriate calming light color for better sleep. Amber light helps us feel calmer and promotes the secretion of melatonin. It may also be related to an improved overall mood and mental health.

We might not realize how we are constantly surrounded by modern light sources that emit blue light including electronic devices such as laptops, TV’s and smart phone screens. All of these devices emit a high level of blue light that disrupts melatonin secretion and confuses your natural circadian rhythms.

Opting for amber light in your house protects your eyes from harmful blue light and can help you fall asleep easier. The warm amber-spectrum light demonstrates no negative effect on melatonin secretion. Amber light mimics the amber-wavelength light of candlelight which makes it an ideal calming light color for sleep allowing you to fall asleep quickly.


●     Red light

Red light is by far the best calming light color for sleep. Choosing a red light as a nightlight ensures that you don’t disrupt your circadian rhythm. So switching to a red light a few hours before going to bed will surely help you fall asleep easier. Additionally, if you wake up during the night, being exposed to red light will make it easier to fall back asleep than being exposed to blue or green light emitted from white light.

So what makes red light the best color light for sleep? Our eyes have photosensitive cells which are receptive to light and control our body’s internal biological clock. These photosensitive cells are sensitive to different wavelengths which send signals to our brain. A recent study by Ohio State University concluded that our eyes are most sensitive to blue-green light which is emitted from white light.

Blue light absorbed by our eyes sends a signal to our brain indicating that it is daytime. So our internal biological clock gets confused and inhibits melatonin secretion. Melatonin is a chemical released in the brain that makes you feel sleepy. A study also shows that red light also removes green light which makes it the most relaxing light color for sleep as green light also inhibits natural melatonin secretion.


When should you use amber light and red light colors?

Amber lights specifically designed to block blue light should be used as a general-purpose bulb to use throughout your house. It will provide you with sufficient brightness and color while still avoiding 100% of the harmful blue light. So you can replace the common light bulbs in your house with amber lights which provide a nice warm relaxing atmosphere that protects you against harmful blue light.

Red light bulbs that are specifically created to emit zero blue and green light are slightly dimmer. Ideally these are used in bedrooms and bathrooms as reading lamps and night lights. Using a red light bulb will provide you with enough light to read and see during the night and give off a sunset deep orange to red glow. These red light bulbs ensure that you get the best possible sleep.

The best is to have a combination of both amber and red light bulbs in your house. The amber light bulbs can be used in your overhead lighting throughout the home, and the red-light bulbs can be used a few hours before bedtime.


What are the benefits of calming colors for sleep?

If you’re a restless sleeper or a sleep-deprived parent you know better than anyone how valuable it is to have a good night’s sleep. It’s a widely known fact that a bad sleep and the resulting tiredness have a negative effect on our overall health and make us less productive. The light we are exposed to plays a huge role in our capacity to sleep.

Let’s have a closer look at some of the main benefits of using the most relaxing light colors for sleep:

  • Natural melatonin secretion
  • Feeling calm and in tune with your internal biological clock
  • Sleep inertia prevention
  • Feeling more alert and concentrated when you wake up
  • Better and more restful sleep
  • Muscle relaxation

When it comes to using red light and amber light, it’s important to note that having a red coloured light bulb or an amber coloured light bulb is not enough. It’s not about the visual color visible to our eyes. Red or amber lights that haven't been specifically designed to help with sleep still emit blue and green light even though you can’t see it with the naked eye. Using these kinds of lights can still disrupt your sleep as your eyes will absorb the blue and green light emitted from them.

To have a blue light and green light free light bulb, you need to have a pure amber light and pure red light which emit zero blue and green light. So the lights need to be specifically designed to only emit the specific wavelengths without emitting blue light and green light wavelengths which are high energy colors.
