"To combat worry, Hallowell suggests that people should not worry alone, because people are much more likely to come up with solutions when talking about their concerns with a friend. As well, he urges worriers to find out more information about the issue that is troubling them, or make sure that their information is correct. Another step to reduce worry is to make a plan and take action and take "care of your brain" by sleeping enough, getting exercise, and eating a healthy diet (without a "lot of carbs, junk food, alcohol, drugs, etc). Hallowell encourages worriers to get "regular doses of positive human contact" such as "a hug or a warm pat on the back".Finally, he suggests that worriers let the problem go rather than gathering them around themselves."
