Light Color and Mental Effort Intensity (02-17-17)

Lasauskaite and Cajochen linked mental effort intensity and light color.  The team “tested effort-related cardiac response under four lighting conditions and found that it decreased with color temperatures [i.e., as light got bluer].  Thus, blue-enriched light in offices and schools might . . . preserve resources during cognitive activities.”
