The health risks of light at night. The Good, the Bad, and the Time of Day of Bioactive Blue Light.
Edison’s invention of the light bulb conquered the night, or so we thought. Now, the night seems to be striking back. On almost a regular basis, we see headlines extolling the harmful effects of artificial light at night. “Your smartphone is making you fat!” says one headline. “Light at night is contributing to the diabetes epidemic and increases your chance of heart attacks!” says another. “Working at night increases your chance of getting breast or prostate cancer by over 50%, and if you do get a cancer, the wrong light will prevent the chemotherapy from working.” A map of light at night exposure in Israel correlates with the map of increased rates of breast cancer in Israel.
To make matters worse, exposure to the wrong light at night can lead to depression and mood disorders.
Dr. Martin Moore-Ede will be presenting new research at the "Lighting for Health and Wellbeing" Conference in a presentation titled "Taking the Obesity and Diabetes Risk out of Light at Night" inNewport Beach, CA on July 27, 2017.
The largest study ever done on diabetes levels around the world revealed last year that the global cost of diabetes has reached $825 billion. Exposure to blue light at night has been found to increase the risk of obesity and diabetes - and with the rise of conventional LEDs in recent years, part of the increased diabetes cost could be due to increased blue light exposure.
CIRCADIAN Light fixtures are autonomous, easily installed by any electrician and provide high quality white light with the optimal bio- active blue levels based on time of day, season, and location.The Health Problem with LEDs
Most LED and fluorescent lights on the market today increase obesity, diabetes, heart disease risks, and reproductive problems and cause up to a 50-65% higher rate of breast cancer, prostate cancer, and gastrointestinal cancer when used in the late evening or at night. Mounting medical evidence shows they provide too much Bio-Active Blue during the night, and too little during the day, leading to circadian rhythm disruption, mood and health disorders and low productivity.
