Wikipedia Meaning and Definition on 'Worrywart'
Worry is thoughts and images 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, usually personal issues such as health or finances or broader ones 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).
Excessive worry is the main component of Generalized anxiety disorder.
One theory of anxiety by Liebert and Morris in 1967 suggests that anxiety consists of two components; worry and emotionality. Emotionality refers to physiological symptoms such as sweating, increased heart beat and raised blood pressure.[See more about Worrywart at Dictionary 3.0 Encyclopedia]
