Setting a timer to signal yourself to practice deep breathing every hour or half hour is a good way to remedy frequent panic attacks. Set aside a few minutes to concentrate on taking some deep, relaxing breaths. This will level out your oxygen intake and prevent hyperventilation. Maintaining this activity will create a habit after a while.
Figuring out what triggers an attack is a good step in handling it. If you are upset about something that someone has done and you are worried about speaking with him or her regarding the situation, a panic attack could be triggered. It is important to express your views in a healthy and productive manner, so that you do not feel overwhelmed and have a debilitating panic attack.
