How Lights Affect Sleep

Your sleep environment has a bigger impact on the quality and quantity of your slumber than you may realize. Today we’re focusing on one aspect of the slumber environment – light – and how it can affect your sleep. All light from the sunlight that streams through your window to the lamp on your nightstand can change or alter your rest patterns. First, we’ll take a look at how light affects the slumber cycle and move into how you can use light to get the full seven to nine hours of sleep you need.
Run Down on Light and the Sleep Cycle
Sunlight acts as the body’s natural slumber regulator. Special cells in the eyes absorb the blue spectrum light that filters through the Earth’s atmosphere from the sun. The cells then send direct signals to the circadian region of the brain, which then suppresses sleep hormones. As the sun starts to go down and blue light levels decrease, relax hormone levels rise and preparation for the slumber cycle begins.

However, sunlight isn’t the only source of blue light. High-efficiency (HE) light bulbs and electronics like televisions and laptops are just a few of the other sources of blue light that could affect your slumber cycle. Because the brain is highly sensitive to all kinds of light, it has to be managed carefully in the bedroom.

Paint the Room for Sleep
A paint’s sheen, no matter the colour, affects light. Any paint in a semi-gloss will reflect more light than a satin, matte, or flat finish, especially pastel and neutral shade. If your bedroom is flooded with natural light, opt for a sheen that will absorb rather than reflect light and brighten the room.

You have to think carefully about the color too because colour has a psychological impact. Certain shades like blue, green, and cool neutrals like gray calm and soothe the mind, enhancing the relaxation needed for sleep. A survey of 2,000 Britons found that sleeping in a blue room increased nap times by 17 minutes. Other shades that performed well were gray/silver and pale yellow.

Manage Natural Light
At night, the bedroom should be kept as dark as possible. But, the sun may rise much sooner than you actually need to be out of bed. Blackout curtains, heavy drapes, blinds, and even shutters are options to help you keep light levels low at night, but still, let you control light levels.

If you’re looking at a remodel situation, think about the placement of your windows. The sun rises in the east and sets in the west. If you have the option, west-facing windows will let direct evening light into the room when it’s less likely to interfere with your rest since most people go to bed after dark. That doesn’t mean you have to skip east-facing windows altogether but they’ll have to be managed with window treatments more so than their west-facing counterparts.

Keep Tabs on Other Light Sources
All artificial lighting has the potential to disrupt the rest cycle. We suggest using incandescent rather than high-efficiency light bulbs. Watch out electronics too. Of course, there are some that enhance your sleep like a CPAP or white noise machine, but televisions, smartphones, and laptops can be sleep disruptors even when they’re not in use. Twenty-four-hour notifications and the temptation to watch another episode or scroll through social media can keep you from getting a full night’s rest.
Conclusion  on how lights affect sleep
Your room doesn’t need to feel dark and uninviting to promote good rest. It’s a matter of understanding how to manage the light so that it gives you the ambiance and feel you want with the light control to promote healthy sleep. Sometimes it’s a small change and other times it’s the opportunity to change the entire look and feel of your room so that it truly is a sanctuary from the of the outside world.
