Sleep deprivation

=== The Internet ===
A study published in the [[Journal of Economic Behavior and Organization]] found that broadband internet connection was associated with sleep deprivation. The study concluded that people with a broadband connection tend to sleep 25 minutes less than those without a broadband connection; hence, they are less likely to get the scientifically recommended 7–9 hours of sleep.<ref>{{Cite news|title=Broadband internet causes sleep deprivation, a new study finds|work=ScienceDaily|url=https://www.sciencedaily.com/releases/2018/08/180802102340.htm|access-date=10 August 2018}}</ref> Another study conducted on 435 non-medical staff at [[King Saud University]] Medical City reported that 9 out of 10 of the respondents used their smartphones at bedtime, with social media being the most used service (80.5%).
