Worry refers to the thoughts, images and
emotions of a
negative nature in which mental attempts are made to avoid anticipated potential threats. As an
emotion it is experienced as
anxiety or concern about a real or imagined issue, often personal issues such as health or finances, or broader issues such as environmental pollution and social or technological change. Most people experience short-lived periods of worry in their lives without incident; indeed, a moderate amount of worrying may even have positive effects, if it prompts people to take precautions (e.g., fastening their
seat belt or buying fire insurance) or avoid
risky behaviours (e.g., angering dangerous animals, or
binge drinking).
