New research has indicated that tablets, smartphones and computers are contributing to a nation becoming sleep deprived.
The survey indicated that almost six in ten people are not getting in excess of seven hours of sleep each night. It has also shown that 78% of Brits experience exposure to computer blue light before they go to bed. This light is known to be disruptive to a good night’s sleep.
Of the 2,149 adults questioned, the figure rose to a massive 91% for those aged between 18 and 24 years.
Professor Richard Wiseman, a psychologist, has stated that the blue light emitted from these computing devices is responsible for suppressing the production of a sleep-inducing hormone. This makes it important to avoid the use of these devices prior to bed time.
The number of hours’ sleep required varies from one individual to another, however, adults are said to need a minimum of seven to eight hours of sleep each night. Teenagers require about nine hours of sleep a night, but rarely reach this target.
The National Sleep Foundation conducted a poll last year about sleep patterns and it has been found that the number of people not getting sufficient sleep has risen by one fifth since then. Professor Wiseman has stated that the increase is massive and extremely worrying because less than seven hours of sleep each night is associated with many problems, including heart attacks, weight gain, cancer and diabetes.
During the survey, participants were questioned on the use of smartphones, tablets and computers two hours prior to going to bed. The survey investigated the dreams of the participants and found that they were not always good. Only 10% of the participants stated that they had pleasant dreams.
