Learn about the impacts human-centric lighting has on health, mood, and sleep quality

Circadian Rhythm Lighting: Does It Improve Health and Wellbeing?

Wellness is a trending topic in home design these days. And it’s a worthy conversation to have: How can we design spaces that help us feel better and healthier day-to-day? Home lighting is a key component of wellness design, and circadian rhythm lighting is the technology at its center. Human-centric solutions aim to use lighting technology that helps keep our bodies’ internal clocks in balance throughout the day.

Keep reading to learn how circadian rhythm lighting contributes to a healthier, more balanced environment in your Scottsdale, AZ, home.

Reduce the Negative Health Effects of Electric Light

The human body’s internal sleep/wake clock — the circadian rhythm — was designed to cycle in tune with the rising and setting of the sun. The rising sun tells our bodies it’s time to wake up and be productive, while the setting sun triggers the production of melatonin, a hormone that encourages relaxation and sleep. However, most of us don’t spend enough time outside under the sun or inside with the windows open. Instead, the majority of our daily light exposure comes from artificial sources.

Artificial light can disrupt the body’s natural circadian rhythm, especially at night. Prolonged exposure to electric light has been associated with headaches, eye strain, stress, burnout, and poor sleep.

Circadian rhythm lighting aims to bring the powers of natural light indoors. It uses advanced technology to generate light that mimics the correlated color temperature (CCT) and brightness of sunlight. Dynamic, tunable lighting systems adjust the CCT and intensity of light bulbs throughout the day to reflect the shifting patterns of the sun. This type of human-centric lighting can help reduce the negative effects of electric light and improve your overall wellness at home.

Feel More Alert During the Day

During the day, the sun produces bright light with cool blue and white color temperatures. A tunable lighting solution like Ketra by Lutron can generate light with color temperatures ranging between 4,000K to 10,000K (the color of a bright, blue sky) in your home spaces. Bright light with cool blue tones promotes more alertness, energy, and focus so that you can complete work tasks, chores, or relaxing activities feeling energized and motivated. 

Sleep More Restfully at Night

In the late afternoon and early evening, the sun produces soft light with warm yellow and orange color temperatures. Ketra tunable lighting can generate light with color temperatures ranging between 1,400K to 3,500K in your home spaces. Soft light with warm orange tones promotes relaxation and ease to help you wind down and prepare your body for restful sleep at the end of the day.
