Depends on the person,social media can be an addiction and you can reduce it by deleting social media that you don't use,be mindful on the time spent online and if you want turn off the notifications
I think it's good to avoid looking at your phone in social settings. The amount of times I've been with friends and the moment conversation dies we all go to our social media to pass the time, it becomes reflexive. So definitely need to work to keep it in it's place
Biggest thing is turning your notifications off for all your apps and turn your phone to silent so you only look at it when you are choosing to. Will reduce your screen time massively
