Why do most hospitals have green curtains and bedsheets?
Others answers (1)
Green is used in hospitals because it's thought to be easier on the eyes and to help lower the stress levels of both patients and health-care people.The reson behind this pleasant look is, as we know that daylight is made up of seven wavelengths of light (violet, indigo, blue, green, yellow, orange and red). A particular colour reflects a particular wavelength of light (to our eyes) and absorbs the rest of the wavelengths. The wavelength of green is of 550 nanometre (1 nm = one billionth of a metre) which is soothing to the eyes and helps in quick recovery.
