Okay, so you want to know how to prevent panic attacks.
In this article I am to clearly and concisely cover the main points.
I will take a look at the common symptoms you may experience, techniques for coping, and treatment options available to prevent them happening in the future.
Symptoms There are a wide range of symptoms, both physical and psychological/emotional that can indicate that you are suffering from a panic or anxiety attack.
These symptoms usually come on suddenly, without warning, and can be very frightening for the person experiencing them.

• Sweating and trembling.
  
• Palpitations or a thumping heart.
  
• Feeling short of breath, sometimes with choking sensations.
  
• Hot flushes or chills.
  
• Feelings of unreality, or being detached from yourself.
  
• Chest pains.
  
• Feeling dizzy, or faint.
  
• Fear of dying or going crazy.
  
• Feeling sick.
  
• Numbness, or pins and needles.
  

How To Cope With Panic Attacks There are a number of techniques you can use to calm yourself down when you have an attack like this.
These include:

• Breathe into a paper bag - This is good for calming down your hyperventilation (breathing too fast).
  It causes you to inhale your own carbon dioxide, and helps to re-balance the acid level in your blood.
  
• Breath as deeply and slowly as you can.
  This will calm you down, both physically and emotionally.
  

How To Prevent Panic Attacks In order to prevent these kinds of attacks of anxiety from happening in the future, there are a number of things you can do:

• Learn to live more in the moment.
  By being more aware of the present moment, you will be less worried about what may or may not happen in the future (even in the very near future).
  
• Become more aware of your breathing throughout your day.
  Whenever you remember, take a moment or two to just become aware of the natural flow of your breathing.
  This will naturally keep you calm throughout the day, and also keep you more focussed on the present moment as mentioned above.
  
• Consider joining a Yoga class or learning how to Meditate.
