The first flaw is that it's not completely accurate, seven to eight hours of sleep, while recommended for adults is just an average.
And while messages have to be simplified for health communication to the public, sometimes important nuances get lost.
So yes, it's true that not getting enough sleep in the long term is associated with health problems like cardiovascular disease,diabetes and depression.
But fixating solely on seven to eight hours ignores the fact that there's a range of sleep that people need .
The duration of a good night's sleep can be different for different people.
The second flaw with this kind of doomsday message is that can be counterproductive especially for people who do have trouble sleeping.
But having all of that sleep data is causing some people to become obsessed with it ,so much so that it's leading to a condition some call "orthosomnia",a preoccupation with the constant need to achieve perfect sleep.
And this condition,Ironically, is causing more sleep problems.
