IMO The last thing you see in your last social media task probably has an impact

So make sure you end your scrolling on a positive note as much as possible or at the very least on neutral content before going to another task or putting your phone away altogether.

It's better the last thing you see is a happy puppy after it has been rescued or a nice delicious meal. I'd rather end my scrolling on that than on a headline about someone that got murdered or stuff about war and shit.

Stay safe.
