ISLAMABAD: One hour a day on social media can derail your sleeping pattern, a recent study warns.
The report by Canadian researchers was commissioned to assess why so many young people struggle to sleep eight hours.
They found the root problem to be social media: those who spent at least 60 minutes on WhatsApp, Facebook or Snapchat suffered more sleep issues than those who did not.
The more time they used the apps and sites, the less sleep they got.
The study, carried out by the Children's Hospital of Eastern Ontario Research Institute, found teenage girls were the most addicted to social media and were therefore more likely to be sleep deprived, but it affects boys just the same.
'Waking up during light sleep will leave you feeling refreshed and alert. However, waking during deep sleep will not. If you sleep too long and miss the light sleep at the end of a nap, chances are you will wake up feeling sluggish and drowsy.
'If you do experience feeling drowsy after a nap, don't worry – this feeling is temporary and will go away after a while.'
She says that another option is to have a brief 'power' nap of 10-15 minutes – which can significantly improve alertness, cognitive performance and mood almost immediately after waking. The benefits typically last for a few hours.
'Power naps are great because you won't experience any sluggish or drowsy feelings after waking,' said Dr Lovato.
'This is because you do not enter any deep sleep during this brief time.
Research suggests, a brief, early-to-mid-afternoon nap provides the greatest rejuvenation when compared to naps at any other time of the day.
However, if you're struggling to stay awake, a brief nap taken at any time can be help keep you alert.
