[ Color and Circadian Rhythm ]

24 different simulations were conducted to show the effect of room color on melanopic flux as an indicator for occupants’ circadian rhythm. Half of the simulations were performed in low-intensity mode and half of them used high-intensity lighting mode in an unfurnished room at night. The results suggested that:

• Far from what interior designers suggest, that cold colors in the bedroom will have a soothing effect on occupants, they will adversely affect occupant’s circadian rhythm by suppressing melatonin secretion at night.

• High CCT LEDs and high light intensity at night can also suppress melatonin secretion that can adversely affect occupants’ health.
