Are there habits that make anxiety disorders more likely?

Not Really: You might be thinking of various habits that tend to go along with worrying aobut things. These habits are actually produced by anxiety, instead of being a cause of anxiety. However, there are healthy habits related ot rest, exercise, breathing, and meditation that can decrease the severity of anxiety.

Sure: Many things can contribute: poor sleep, poor nutrition, lack of exercise, using stimulants like caffeine, nicotine, or substances (either stimulating or sedating). Problematic work environments & stressful relationships can also contribute.

As with everything: Else, not taking care of yourself makes anxiety more likely. Not sleeping well, not handling stress well, not exercising regularly and not having balance in your life will all make anxiety more likely. But some anxiety disorders also have a genetic component. Taking good care of yourself will even help your treatment.
