Olivia Munn does exercise to fight OCD

London: Actress Olivia Munn works out every morning to combat obsessive compulsive disorder (OCD).

The `Deliver Us From Evil` actress said she found the daily sessions with a personal trainer help ease the symptoms of the anxiety disorder, reportedly.

"To combat my OCD, a trainer helps me work out every day 6 am. I don`t know what he does, but it helps. We talked over the weekend," she said.

The 33-year-old actress also admitted she never brushes her hair and isn`t faithful to using any particular product on it. "I`m Chinese so I have thick hair, which I don`t brush, and use different products. I love vintage shopping."
