Those who use electronic devices like smartphones and tablets before bedtime end up losing sleep or getting poor nap time, a review of nearly two dozen prior studies suggested.

A review of twenty prior studies by researchers from King’s College London revealed that children who used smartphones and tablets at bedtime more frequently either lost part of sleep or got poor sleep. Those students were found to be excessively tired during the next day in the school.

Lead researcher Ben Carter warned that use of electronic devices at bed time can distract their attention and push back bedtimes, and light from the screen may confuse their body’s biological clock.

Aside from being sleep deprived, a person could face risks of developing other diseases. This conclusion hardly comes as a shocker as everyone knows importance of sleep as well as the adverse consequences of taking it for granted.

The researchers stressed that some people may underestimate a sound sleep’s importance but it may eventually make a big difference to a person’s overall health.

The study, which technically reinforces previous claims that difficulty in concentration or being moody results in sleep deprivation, appeared in a recent edition of the journal PLOS ONE.
