I've read in one article that says that using a light which emits a natural-like light is advisable for studying. white light may be too harsh and it also suppresses melatonin production five times more than yellow light. Currently I am using a a study lamp with a white LED light.
Ganahan unta ko ug light na medyo mo emit ug daylight effect ba kanang makita gani nimo sa buntag, when the sun is still young...
Do you prefer to use a white light or a yellow light specifically during studying?
