Peer reviewed workplace studies show that the intensity, spectrum, timing and steadiness of light influence alertness, sleep and performance. Electric, magnetic and wireless exposures vary widely from one workplace to the next.
Workplace lightingBetter office light, better alertness and sleep
Office workers under blue enriched daytime lighting reported better alertness, performance and concentration, less evening fatigue and better sleep quality than under standard lighting.

Workplace lightingMorning light linked to better sleep and mood
Office workers who received more circadian effective light in the morning fell asleep faster, slept better and reported lower depression scores.

FlickerFlicker changed brain activity and performance
Flicker from conventional fluorescent lighting changed brain activity (EEG) in flicker sensitive people and was linked to faster but less accurate work, compared with flicker free lighting.

MeasurementExposure depends on distance and setting
Measurements across a utility workforce showed magnetic and electric fields varied widely with the equipment nearby, the task and how close people were. Exposure is something you measure, not assume.

WirelessWorkplaces carry many overlapping signals
Frequency selective measurements in public indoor workplaces found radio frequency coming from many sources at once, each identifiable by its frequency band.

Fields and lightSteady fields plus low light: lower melatonin
In 142 electric utility workers, those with the most steady magnetic field exposure had lower levels of a melatonin metabolite after work. The effect was stronger in workers who also got the least light during the day, which is why light and fields are worth measuring together.

Lighting has the strongest workplace evidence, so it comes first. Research on EMF and health is still developing, and some findings are mixed. FieldWise reports what is measured in your space, compared to Building Biology SBM-2015 guidelines. It does not diagnose or treat any condition. See the full research library →
