STONEHAM, MA ---- The American Petroleum Institute (API) has released new guidelines for nighttime lighting that have wide-ranging implications for millions of shiftworkers. As part of the revised ANSI RP-755 standard for workplace health, safety, and performance, the API is directing 24/7 workplaces to be well-lit and utilize light sources at night that minimize circadian disruption.

Human-Centric Lighting in Control Rooms
How Light Impacts Employee Performance & Health

Women who slept with the lights or TV on had a higher risk for obesity.

Sleeping with the lights on may increase the risk for obesity. Researchers prospectively followed 43,722 generally healthy women, average age 55, for an average of six years.

At enrollment in the study, the women reported whether they slept with lights or a television on in the room.

For hundreds of thousands of years, humans lived under one source of light: the sun. It rose in the morning. It set at night. And evolution programmed our bodies according to that ancient, never-changing schedule.

Then we invented electric lighting.  Now instead of spending our days under the bright sun, most of us spend them in rooms that are relatively dim.

American Petroleum Institute tells members to “minimize circadian disruptions.” That means strip down the blue, at least one expert says.

In an influential move to mitigate harmful blue-tinged LED light at night, the American Petroleum Institute (API) has issued new workplace safety guidelines directing sites to minimize circadian disruptions from light sources.

API, the trade association for the US oil and gas industry, issued the new stipulations early last month in a Recommended Practice (RP) document entitled “Fatigue Risk Management Systems for Personnel in the Refining and Petrochemical Industries,” also known as RP 755.
