Well as you can see from the article i'm not very good at following the advice of the app.

However, I find it is useful a reminder that I need to keep finding ways to increase my sleep.

However, some claim that "acute sleep deprivation is not only not harmful but beneficial in some contexts and that it’s that we are able to adapt to long-term sleep deprivation." - https://guzey.com/theses-on-sleep/

So who knows whats best for us really :-)
