A panic attack is a sudden episode of intense fear that triggers severe physical reactions when there is no real danger or apparent cause. Panic attacks can occur frequently and unexpectedly and are often not related to any external threat. Symptoms of a panic attack can include heightened anxiety and physical sensations of fear, such as increased heart rate, shortness of breath, trembling, muscle tension, sweating, chest pain, nausea, and dizziness. Panic attacks can last from a few minutes to half an hour, but the physical and emotional effects of the attack may last for a few hours. Although panic attacks themselves arent life-threatening, they can be frightening and significantly affect your quality of life. Panic attacks can be treated with a range of therapies including medications, psychotherapy, stress management, and relaxation techniques. If you or someone you know is having a panic attack, its important to stay calm and try to take control of your breathing first. Find a place where you can sit or be comfortable, concentrate on making your breath slow and even, and try to inhale through your nose for 4 seconds, hold it for 2 seconds, then exhale through your mouth for 6 seconds. Its also important to remember that panic attacks always pass and the symptoms are not a sign of anything harmful happening.
