I believe that we should, in everything we do, glorify God's name.
1 Corinthians 10:31 (NIV)
So whether you eat or drink or whatever you do, do it all for the glory of God.
Therefore, hurting yourself with a reason that does not glorifies God's name is not good. It's so bad that I personally consider doing anything that does not glorifies God's name is a sin.
But that is just my opinion. Correct me if I'm wrong.
May the peace of the Lord be with you, always. God bless.
