There’s a hormone called melatonin that’s produced in our brains that’s partially responsible for regulating our sleep-wake cycle. Melatonin makes us sleepy and prepares our bodies for sleep. Exposure to blue light suppresses the production of melatonin in our brains, so that signal for our bodies to get ready for sleep and for us to feel sleepy is missing or weaker than it should be.
