Many of us fall into the same habit – checking our phones before heading to bed. Whether we’re reading through texts, browsing the Internet or checking social media accounts, looking at devices that emit blue light can play havoc with sleeping patterns.
A new survey has found that 78% of adults questioned regularly expose themselves to devices that emit blue light before going to bed. This number rose to an incredible 91% among respondents aged 18-24.
The University of Hertfordshire carried out the survey and commented that the blue light disrupts sleep by suppressing the production of sleep-inducing hormone melatonin.
The recommended amount of sleep for adults is between seven and eight hours a night, with teenagers requiring at least nine. The amount of people getting too little sleep has risen by a fifth since the ‘bedroom poll’ conducted in 2013 by the National Sleep Foundation. Professor Richard Wiseman commissioned the blue light survey and commented on this worrying rise:
“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.”
In the survey, respondents said they used Smartphones and tablets during the two hours just before bed. Another separate survey has also uncovered that under-25s check their phone an average of 32 times every day.
If you are struggling to sleep, limiting your time with blue light emitting devices may help. If you’re still struggling, hypnotherapy may be able to offer support. Find out more on our insomnia fact-sheet.
