I read that some studies show social media can be prejudicial to mental health.

Really? I haven't seen much about that, but it makes sense.

Yeah, they say it can lead to unrealistic comparisons and anxiety.

That’s true; we should be mindful of how it affects us.

Root Explanation
Prejudicial is formed from "pre-" (meaning before) and "judicium" (meaning judgment). The word refers to something that causes harm or damage before a fair judgment can be made.
Memory Tip
Think of something that causes harm or damage 'before' a fair 'judgment' is made — that's why prejudicial means harmful.
