The root cause of panic attacks is stress and the environment around the person. These factors finally resulted in affecting the heart and its functioning. If you have feelings of palpitations, a very fast heart beat or pounding heart beat, a very fast heart rate, etc. then it means that a possible panic attack is on its way. Sweating is one of the most obvious and significant symptoms of panic attack.

Sweating is quite normal and every person sweats in hot conditions or while doing some outdoor activity. But if the sweating takes place without you indulging in any outdoor activity or getting exposed to hot and humid conditions, then there is a cause for concern. And if this sweating becomes excessive or abnormal, then it will be advisable that you consult a doctor and start taking some advice from him.

Nervousness is one of the other symptoms of panic attacks and if this nervousness is followed by trembling and shaking of the hands and legs, then it is possible that there is something emotionally and mentally wrong with you and is a very good signal that you should start taking immediate action. There are lots of people who advocate breathing techniques for tackling all these anxiety problems. All these breathing techniques are good cures for this mental disorder and improper breathing is a signal or warning of a possible anxiety problem that might arise in the future. If there are problems with your breathing or if you believe that you are unable to indulge in deep breathing, then you must be having some problems which would require immediate medical attention.

Sometimes people feel suffocated in an open environment like a playground or they feel like someone is choking their neck. These are very obvious signals of severe panic attacks and such people should be taken to the hospital immediately.

Pain in the chest or some discomfort, feeling of nausea or abdominal distress, feeling of dizziness, fainting sensations, unsteadiness, lightheadedness, feeling things which do not exist or are unreal, feeling of detachment from people and the society, fear of losing control or feeling craziness, fear of an impending death, hot flashes are some of the more common symptoms of panic attacks.
