Experimental: Light 1
Light 1 will have an altered color composition as compared with a standard LED bulb.
Device: Light - alternate
Light will be given during the night to determine its effects on melatonin suppression. This light will be an LED with an altered spectral distribution (different color)
Active Comparator: Light 2
Light 2 will be a standard LED bulb.
Device: Light - standard
Light will be given during the night to determine its effects on melatonin suppression. This light will be an LED with standard spectral distribution
- Melatonin suppression [ Time Frame: 4 Hours ]The amount of declination of salivary melatonin concentrations between the start of the light and the end of the light (4 hours later) will be compared between the conditions.
