Today I've learned that "You look tired" or "You look sick" is an insult, which is not in my culture - I'm from Korea.
Sometimes I want to express my worries for example
- When some colleagues express their tiredness especially when they couldn't sleep well because of some incident in the night when they were on call.
- When someone coughs or sneezes.
What would be nice ways to sympathize or express my concern in English. "You don't look very well" or "Are you okay" would be okay?
Adding some more information here which is hidden in comments.
I was wondering about the manner in English speaking cultures. I thought "You look tired" is generally regarded as an insult as Google says so, but from the opinions in the comments, it seems it's not always true.
And this is a Dan's opinion which is in the comments,
On American professional culture at least, you don’t say anything that communicates this idea. You don’t communicate anything that conveys the idea that the person’s appearance is flawed.
