The University of Hertfordshire in the UK conducted a study that indicates smartphones may be negatively affecting the ability to sleep.
One of the university’s spokespeople said, “The blue light from these devices suppresses the production of the sleep-inducing hormone melatonin, so it’s important to avoid them before bed time.”
In other words, using your phone before bed time may keep you up longer than you want to be.
78% of the adults and an astounding 90% of teenagers in the survey said they use their phones right before going to bed.
A study from the National Sleep foundation suggests that adults and teenagers are getting significantly less sleep than recommended. More than 28 million people in the United Kingdom get less than seven hours of sleep, compared to the 8 hours recommended for adults and 9 hours recommended for teens.
“This is a huge rise, and the results are extremely worrying because getting less than seven hours sleep a night is below the recommended guidelines, and is associated with a range of problems, including an increased risk of weight gain, heart attacks, diabetes and cancer,” said Professor Richard Wiseman.
Put your phone away 30 minutes to an hour before bed time, and you may find your ability to sleep will improve significantly.
