The teacher said it was cold, so put on more clothes. How to reply?

The possible response to this situation is:

1. Thank you for your concern. We will wear more clothes when we go out. You should put on more clothes, too, teacher. Don't catch cold.

Yes, teacher, we have put on thick down jackets, and now we feel very warm. We also wear gloves. I hope the teacher will pay attention to his health and not catch a cold. Thank you for your concern.
