People with panic disorder have sudden and repeated attacks of fear that last for several minutes or longer. These are called panic attacks. Panic attacks are characterized by a fear of disaster or of losing control even when there is no real danger. A person may also have a strong physical reaction during a panic attack. It may feel like having a heart attack. Panic attacks can occur at any time, and many people with panic disorder worry about and dread the possibility of having another attack.
There remains a chance of panic symptoms becoming triggered or being made worse due to increased respiration rate that occurs during aerobic exercise. This increased respiration rate can lead to hyperventilation and hyperventilation syndrome, which mimics symptoms of a heart attack, thus inducing a panic attack. Benefits of incorporating an exercise regimen have shown best results when paced accordingly.
Social anxiety disorder (previously called social phobia): People with social anxiety disorder have a general intense fear of, or anxiety toward, social or performance situations. They worry that actions or behaviors associated with their anxiety will be negatively evaluated by others, leading them to feel embarrassed. This worry often causes people with social anxiety to avoid social situations. Social anxiety disorder can manifest in a range of situations, such as within the workplace or the school environment.
