Our bodies have evolved over thousands of years to follow a natural 24-hour light-dark cycle. We naturally sleep when it gets dark and wake when the sun rises. Eventually, the cavemen invented a fire torch of amber color to see at night. Edison invented lighting 150 years ago and caused havoc to our internal body systems. The introduction of this artificial light interferes with our master clock, which is known as our Circadian Rhythm. Conformance to an appropriate Circadian Rhythm is crucial for our overall health and wellbeing. The natural light cycle interacts with our bodies and regulates our hormone levels.

External interference with our master clock is called Circadian Disruption. Interruption with the normal rhythm puts us at risk for behavioral and physiological issues. Sleep is the bodies best antioxidant and exposure to standard white or blue lighting at night, such as during night shift work, is at odds with our natural internal body clock.

Disruptions to our natural Circadian Rhythm can trigger serious health issues such as obesity, diabetes, cancers and mood disorders. Studies have shown that exposure to the inappropriate kelvin temperatures and nanometers of light in the evening has been linked to increased risks for breast and prostate cancers as well as other issues.

Brain scientists have determined that exposure to the wrong lighting at night can suppress the body’s natural secretion of Melatonin. Melatonin is vital to our overall health and regulates our sleep-wake cycle, metabolism and immune system.

Proper lighting during daylight hours is also important. Daytime lighting tuned at the appropriate 450-490 nanometers suppresses Melatonin and promotes the release of Cortisol and other hormones which improves alertness, awareness and energy.

In the past 10 years, health experts have identified a specific spectrum of light enabling us to simulate the 24-hour natural light cycle. Thus, the birth of WalaLight Healthy Circadian Rhythm LED Lighting. Our passive ceiling mounted technology which mimics the sun/moon/torch phases marries the biological benefits of state-of-the-art controlled lighting with energy savings and long-life provided by LED lighting to bring the appropriate outside environment indoors. Further, our automated control system allows the user to schedule the exact kelvin and dimming of their lights to coincide with a healthy 24-hour circadian cycle, without user intervention.
