A panic attack is a brief period of extremely high anxiety that results in the visceral feelings of fear. These can include tense muscles, lightheadedness, shaking, racing heartbeat, and shortness of breath. Frequent and unplanned, panic attacks are frequently unrelated to any outside threat. A panic attack may linger anywhere from 30 minutes to several minutes. The attack's psychological and physiological impacts, however, might not go away for a few hours.

signs of a panic episode
Anxiety-related symptoms could include:

increased awareness of potential threats and physical signs
A sharp sense of dread, danger, or foreboding fear of losing control, going insane, or dying feeling lightheaded and dizzy tingling and shivers, especially in the hands and arms.

The brain commands the autonomic nerve system to trigger the body's "flight-or-fight" response when it perceives immediate threat. Numerous chemicals, including adrenaline, are released into the body, causing physiological changes. For instance, in order to get ready for physical conflict or fleeing, the heart rate, respiration, and blood flow are all increased.

When the body's "flight-or-fight" reaction is activated when there is no imminent threat, it is said to be a panic attack. When watching television or falling asleep, for example, or when under other seemingly stress-free circumstances, an individual may suffer the symptoms of a panic attack.

Chronic stress, or chronic stress, makes the body release more stress chemicals, such adrenaline, than usual.
Acute stress, which includes going through a traumatic incident, can cause the body to quickly release a lot of stress chemicals.
Chronic hyperventilation: this causes the blood's carbon dioxide levels to drop, which throws off the blood's gas balance.
intense physical activity: this could trigger strong emotions in certain persons.
Overindulgence in caffeine: a potent stimulant, caffeine is found in coffee, tea, and other beverages.
Physical changes may be brought on by illness.

Always consult a professional
If you are unsure whether your symptoms or those of another person point to a panic attack, you should always consult a doctor. To summon an ambulance in an emergency, dial triple zero (000).

It's crucial to visit your doctor for a checkup to rule out any illnesses as the cause of any persistent physical symptoms similar to panic attacks, such as:

diabetes asthma
complaints of the inner ear
hyperthyroidism, or an over active thyroid
cardiac complaints

Steer clear of "self-talk" that draws attention to your symptoms; don't urge yourself to "calm down" or "stop worrying."
Remind yourself that while uncomfortable, panic attack symptoms do not pose a threat to your life. Tell yourself that nothing horrible occurred to you and that you have experienced similar emotions in the past.
