So the experts have been saying for years that it would be better if we all put our phones away long before bedtime, but now researchers have found some data that may prove that true. The findings in Acta Paediatrica involved a study of 5,242 Canadian youths ages 11 to 20 and showed that those who used social media apps like WhatsApp, Snapchat and Facebook for just one hour a day had their sleep affected. 63.6% of those in the study who said they used social media for an hour or less every day received less than the 10 to 11 hours of recommended amount of sleep for their age, while 73.4% of whom said they used social media for an hour or more daily showed even worse sleeping habits.
