The Dane is out for the season with a knee injury.
Vlaar told Villa's website: "I will talk to him, I talked to Gary Gardner last year. It's little things, you have to try to give yourself a good feeling.
"Make yourself happy even if it's hard, because it's a way of helping yourself recover on your own.
"You do have to do things on your own but we'll try to help him as much as we can."
