Sleep Junkie, an American sleep platform, released data from a research study, by having 2012 participants wear smartwatches, limiting the time spent playing with their phones to eight minutes, and then recording periods of rapid eye movement sleep and the time spent falling asleep.

The results found that 78% of people, who played on their phones for some time before going to sleep, took an average of 60 minutes to fall asleep. When the endogenous photoreceptor optic nerve cells of the retina, are stimulated by the blue light emitted from the cell phone for up to 8 minutes, it may keep the body excited for more than an hour.

Researchers explain that when you play with your phone before bed, adrenaline is stimulated and dopamine release increases, leaving the brain in a state of arousal. Even though people know that it is not good for sleep, but still choose to play with their phones.
