Earlier this year, the World Journal of Biological Psychiatry published a paper by a group of prominent psychiatrists that warned of the potential effects of LED lighting on mental illness.

They deal about the influence of blue light on sleep, use of digital healthcare apps and devices, and the higher sensitivity of teenagers to blue light.

John Gottlieb, Clinical Assistant Professor of Psychiatry and Behavioral Sciences at Feinberg School of Medicine in Chicago and an author of the paper said that “My concern about LED lighting followed from a larger, earlier concern about the relationship between light exposure and the occurrence of manic and mixed symptoms in bipolar disorder.”

Excess and poorly-timed light exposure could have adverse effects on manic states and the sleep-wake cycle, he added. The paper has implications for the treatment of mental illness.

Smartphones represent the larger public health hazard,” said Gottlieb. “Streetlights, though, are not benign and together with the entire set of nocturnal lighting for entertainment, traffic, reading, etc contribute to the phenomena of light pollution, which we are becoming increasingly sensitized to.”

Previous studies of sleep disorders in children and adolescents shows an unmistakable and reliable connection between sleep disorders and the and the recurrence of computerized gadget utilization.

Currently, the National Sleep Foundation guidelines suggest not using technology 30 minutes before bed and removing technology for the bedroom. However, there are currently no specific guidelines for people with an underlying mental illness or sensitivity to circadian disruption.

As LED technology has rapidly spread across the globe, the focus has been on the visual element and the energy-saving element. Now, scientists, health professionals, and the LED industry are working to minimize the blue light in LEDs and create customizable lights that won’t harm those suffering from psychiatric disorders.
