One hour of exposure to bright light before bedtime almost completely shuts down the production of melatonin in preschoolers and keeps it suppressed for at least 50 minutes, a US study has found.

In response to the proliferation of digital technology, researchers assessed the physiological impact night-time light exposure has on the circadian system of children.
