Red Light vs Blue Light
The light receptors in the eyes that affect the circadian rhythm are especially sensitive to blue light. Blue light suppresses melatonin and causes the body to maintain alertness. If you are regularly viewing blue light at night your body will be convinced that it is still daytime, which can disrupt the circadian rhythm and decrease sleep quality.
Circadian rhythms are not affected by red light, making it one of the best lights to use at night. Research has shown that red light exposure can improve sleep and increase melatonin.
Reducing all other lights and switching to red light at least 60 minutes before bed will signal and prep your body for sleep.
Night Shift mode on iPhones reduces some blue light, but not all. Did you know there is a way to remove all blue light completely from your phone’s screen?
