Blue light tells your brain it’s daytime, which suppresses the production of a relaxing hormone (melatonin) that’s naturally released by the body at bedtime. While this is fine during the day, looking at your phone at night tricks your brain into thinking it’s daytime, making it harder for you to switch off and fall asleep.
