Just one energy drink a month can shorten sleep time and increase likelihood of insomnia, study shows

Packed with caffeine and often loaded with sugar, we turn to energy drinks when we're looking for a boost. However, that afternoon pick-me-up can have turn in to a late night sleep disruptor, with studies indicating that an energy drink buzz can linger long past bedtime. And new research has shown that it isn't just those who regularly enjoy energy drinks feeling the effect: even casual consumers might find energy drinks are causing them to miss out on sleep.

Experts surveyed a group of 53,266 students aged between 18 and 35 regarding their energy drink consumption and sleep habits. The study, published in the BMJ Open Journal, found that daily consumption of energy drinks correlated with up to a 33 minute later bedtime, a 25 minute later wake time, a reduced sleep duration, an increase in the time it took to fall asleep, and a higher chance of suffering from insomnia. That's essentially everything from when you climb into bed at night to when you drag yourself out the next morning.
