You may think your e-reader is helping you get to sleep at night, but it might actually be harming your quality of sleep, according to researchers. Exposure to light during evening and early nighttime hours suppresses release of the sleep-facilitating hormone melatonin and shifts the circadian clock, making it harder to fall asleep at bedtime.Ummmm.... this is probably facilitated a lot by orexin too. Orexin production is stimulated by the same optical neurons as melatonin.
So... "internet addiction" may not be a reward system malfunction as psychologists would like you to believe... but some sort of intuitional self therapy for sugar poisoning?
I'm shocked. Shocked I tell you.
