I think...when we think negatively about ourselves hearing compliments or praises make us feel uncomfortable. Maybe, Not always the case just my personal observation...
A long time ago when my self-esteem was low...I don't like compliments...when people say nice things about me I don't believe them...compliments make me feel uncomfortable.
I also find it a bit annoying because I feel like they are not sincere about it... And all the nice things they say about me are lies and not true and they only want to make me feel good about myself Or maybe they want something from me that's why they shower me with compliments
It changed when I learned to appreciate and embrace myself praise God

Now I can receive compliments with a happy heart and a thank you...I think it is nice not only it can improve your mood it can improve the other person's mood also most especially when it's sincere ☺
