Should you use night mode to reduce blue light?
Blue light - whether from the sun or from the screens we use - wakes us up and stimulates us. This also means too much blue light exposure late at night from phones, tablets or computer screens can disrupt our ability to fall asleep.
Because blue light has been proven to affect the body’s circadian rhythm, our natural wake and sleep cycle, limiting screen time to one to two hours before bed and using night mode on electronic devices is a good idea for minimizing blue light exposure affecting our ability to fall asleep.
Although blue light does not cause any damage to the eye, decreasing blue light exposure and limiting screen time and brightness can help people sleep better and feel more comfortable.
