Panic Attacks: What They Are and Why They Feel So Intense
Photo by Shvets
A panic attack is one of the few experiences where your body can feel like it is in danger even when nothing around you has changed. It can start in the grocery store line, while driving, in a meeting, or at home on the couch. The shift is fast. Your chest feels tight. Your heart rate spikes. Your breathing changes. Your brain starts searching for an explanation.
Most people do not interpret it as “anxiety.” They interpret it as a medical emergency or a loss of control. That is part of why panic feels so intense. The sensations are sharp, unfamiliar, and convincing.
This article will help you name what is happening in plain terms, understand why the symptoms escalate so quickly, and focus on what actually helps in moments of panic.

Why Panic Attacks Often Start During Otherwise Normal Periods
When Your Nervous System Has Been Running Near Capacity
Panic attacks often get described as random. In real life, they tend to show up when your system is already running close to the edge.
That edge is not always obvious. It can build quietly. People are still working, parenting, functioning, and answering texts. The strain sits underneath and shows up through the body.
Physical Factors That Increase Panic Sensitivity
Common reasons panic shows up include sleep debt. If you are getting less sleep than your body needs for a few nights in a row, your nervous system becomes more reactive. Your baseline is higher. Normal sensations start to feel louder.
Caffeine is another practical factor. It increases heart rate and alertness. That is not a problem until your brain starts interpreting those sensations as danger. The same is true for nicotine, energy drinks, and some pre-workout supplements.
Illness can also trigger panic. A cold, flu, lingering cough, or congestion changes breathing. If you feel short of breath, even mildly, the threat system notices. If you have a history of panic, your brain may treat that change as a warning signal.
Ongoing Life Pressure Without Resolution
Life stress can be part of it, but not in the vague sense. The factors that tend to matter are sustained responsibility, conflict that is not getting resolved, financial pressure, job instability, grief, or ongoing uncertainty. When your brain cannot predict what is coming next, it stays on alert.
Hormonal shifts can also play a role. Many people notice increased panic symptoms around PMS, postpartum periods, perimenopause, or after stopping or starting hormonal contraception. That does not mean panic is “hormonal.” It means physiology can raise the volume on sensations your brain already monitors.
Why Panic Often Feels Out of the Blue
Sometimes the trigger is overstimulation. Too much screen time late at night, constant notifications, loud environments, or long stretches without quiet. Your system does not reset, so it becomes easier to tip into a fight-or-flight response.
In many cases, panic is delayed. The body holds it together during the busy stretch, then collapses when you finally slow down. People often have their first panic attack on a weekend, after a deadline, or after travel.
What Panic Attacks Feel Like Before, During, and After
What Happens in the Body During a Panic Attack
During a panic attack, the body sensations usually lead. Thoughts follow.
The most common description is a sudden surge of physical alarm. Heart pounding. Chest pressure. A feeling of not getting enough air. Light-headedness. Heat rushes or chills. Shaky hands. Nausea. Tingling in the fingers, lips, or face. A sense of unreality, like things look slightly off.
The mind then tries to solve the problem quickly. It lands on the most serious explanation it can find. Heart attack. Stroke. Fainting. Losing control. Going crazy. Dying.
People often feel embarrassed by these thoughts later, but in the moment they fit the sensations. Panic does not feel like worry. It feels like imminent threat.
Early Signals and the Aftermath
Before an attack, some people notice subtle signs. They may feel slightly off, keyed up, or restless. They may start checking their breathing. They may have trouble focusing. They may feel a tightness in the chest or throat that they cannot ignore.
Other people do not notice anything until it hits. That does not mean it is random. It means the early cues were small, and the threat system jumped in quickly.
After the attack, there is often a crash. People feel drained, foggy, sore, and sensitive to stimulation. Some describe it as a “panic hangover.” This matters because it can create a second problem: fear of the after-effects.
How Panic Starts Changing Everyday Choices
Day to day, panic often changes behaviour even when the attacks are not happening. People start scanning for sensations. They check their pulse. They test their breathing. They avoid exertion because they do not want their heart rate to rise. They avoid heat because it makes them feel flushed. They avoid driving, meetings, stores, or being alone.
Some people start building “escape plans” for normal situations. They sit near exits. They map the closest hospital. They keep water, gum, mints, a paper bag, or a medication close by. These behaviours can bring short-term relief, but they also train the brain to treat panic sensations as dangerous.
Over time, the fear shifts. It becomes less about the original trigger and more about the possibility of having another attack. This is how panic grows legs. The panic attack becomes the event you are managing your life around.
What’s Driving Panic Beneath the Surface
The Body’s Threat Response Activating Too Fast
A panic attack is a threat response. The problem is not that your body has a threat system. The problem is that it activates when there is no external danger, then treats the internal sensations as proof that danger exists.
When the threat system turns on, adrenaline increases. Heart rate rises. Blood flow shifts. Muscles tense. Your breathing changes. Your body prepares to act.
It’s basic human physiology. The reason it feels unbearable is that the system ramps up quickly and changes multiple sensations at once.
How Breathing Changes Amplify Panic Symptoms
Breathing plays a major role in how intense panic feels. During panic, many people start breathing faster or more shallowly. That can drop carbon dioxide levels in the blood.
When CO₂ drops too low, you can feel lightheaded, tingly, shaky, and unreal. Your chest can feel tight. Your mouth can feel dry. Your hands can cramp.
Those sensations are not dangerous, but they are alarming. They feel like something is going wrong. The brain interprets them as confirmation of threat, which pushes the threat response higher.
Chest pain is another driver of fear. During panic, chest tightness can come from muscle tension, altered breathing, and the effort of a racing heart. Again, it is not automatically dangerous, but it is scary because it overlaps with cardiac symptoms.
Dizziness is similar. It can come from breathing changes, adrenaline, and blood vessel shifts. If you interpret dizziness as “I’m about to pass out,” fear spikes, and the cycle accelerates.
Why the Brain Assumes the Worst
There is also a cognitive driver: the brain’s pattern-matching. When sensations feel unfamiliar and intense, your brain searches its library for meaning. It does not start with the calm options. It starts with the serious options.
That is a survival feature. In panic, it becomes a false alarm system.
This is why telling yourself “I’m fine” often does not work. The part of the brain running the show is not interested in reassurance. It is interested in safety. It changes course when the body stops feeding it threat signals and when you stop responding as though escape is required.
What Helps Reduce Panic While It’s Happening
The best short-term goal is not “calm.” It is “lower the load.” Panic often worsens when you add effort, add checking, and add urgency.
Simple Ways to Prevent Panic from Escalating
Change the objective: aim to let the wave pass rather than stop it. “Stop it” creates a fight. “Ride it” reduces resistance.
Slow the exhale slightly: do not force deep breaths. A longer exhale helps signal downshift without creating air hunger.
Drop the monitoring: stop checking your pulse, breathing, or symptoms. Monitoring keeps the brain locked on threat.
Stay where you are if possible: leaving instantly teaches your brain that the situation was unsafe. Staying teaches the opposite.
Use a simple anchor: feet on the floor, hands on thighs, name five objects you can see. Keep it concrete and boring.
Reduce stimulation: lower screen brightness, step away from noise, loosen tight clothing, sip water slowly if your mouth is dry.
After the wave, go gentle: do not “make up for it.” Eat something simple, hydrate, and keep the rest of the day lighter.
If your capacity is low, avoid piling on a complicated routine. A complex plan becomes another source of pressure. The most effective response is often the most minimal one.
When Panic Begins Limiting Your Life
Signs Panic Is No Longer Just Occasional
Panic becomes a bigger problem when it starts changing your life.
A single panic attack is frightening, but it does not always turn into a pattern. The pattern forms when fear of the sensations becomes central, and avoidance grows around it.
It may be time to get support if you notice panic attacks becoming more frequent, or if the fear of having one is affecting your choices. Examples include avoiding driving, skipping work meetings, reducing social contact, or avoiding exercise because you fear the physical sensations.
Another sign is constant body scanning. If you are repeatedly checking your breathing, heart rate, or dizziness throughout the day, your brain is treating your body as a threat zone. That tends to increase panic sensitivity over time.
When to Rule Out Medical Factors
It is also worth thinking calmly about medical factors if symptoms are new, unusually severe, or different from your typical pattern. This is not about alarm. It is about ruling out conditions that can mimic panic, such as thyroid issues, cardiac rhythm problems, medication side effects, low blood sugar, or respiratory illness. Many people feel relief once a medical check confirms there is no acute danger, because it reduces uncertainty.
If you have repeated panic attacks and your world is shrinking around them, that is a clear sign the cycle is established and worth addressing directly.
How Therapy Helps Reduce Panic Attacks Over Time
What Treatment for Panic Focuses On
Counselling for panic focuses on changing the panic cycle, not just coping in the moment.
That usually includes learning how your panic pattern works in your body, identifying the safety behaviours that keep it going, and gradually reducing avoidance. A key part is increasing tolerance for the sensations that trigger fear, so your brain stops treating them as proof of danger.
Approaches often include CBT and exposure-based work. ACT can help reduce the struggle with sensations and the constant attempt to control internal experience. The goal is functional freedom, not perfect comfort.
Accessing Counselling Across Alberta
Phone and online counselling can be a practical fit for panic, especially when leaving home or sitting in an office feels like part of the problem. Support is available across Alberta through video and phone sessions.
Frequently Asked Questions About Panic Attacks
What are the most common panic attack symptoms?
People commonly report a racing heart, chest tightness, shortness of breath or air hunger, dizziness, nausea, shaking, sweating, tingling in hands or face, and a sense of unreality. The exact mix varies. The common thread is that the sensations feel urgent and hard to ignore, which pushes the brain toward catastrophic interpretations.
What’s the difference between a panic and anxiety?
Anxiety is often a sustained state. It can build over hours or days. Panic is usually a spike. It peaks quickly and brings a cluster of intense physical symptoms. People often feel panic in the body first, then fear follows. With anxiety, worry and mental tension are often more central, even if the body also feels activated.
Can a panic attack make you pass out?
It is uncommon. Panic usually increases heart rate and blood pressure, which makes fainting less likely. People often feel like they will faint because of dizziness, breathing changes, and adrenaline. The sensation is real, but fainting is not the typical outcome.
How long do panic attacks last?
The strongest part of a panic attack often peaks within about 10 minutes, though it can feel longer. The body can stay keyed up afterward, leaving you tired, foggy, or sensitive for hours. That “after” period is part of why people start fearing the next one, even when the peak is brief.
Do panic attacks come out of nowhere?
They can feel that way. Often there are practical contributors in the background, like sleep loss, illness, caffeine, dehydration, hormones, conflict, or prolonged stress without recovery. The trigger can be a body cue you would normally ignore, like a skipped breath, a flutter in the chest, or a moment of dizziness. If your system is already loaded, that cue can set off the threat response.
Why do panic attacks feel like a heart attack?
Because the symptom overlap is strong. Panic can cause chest pressure, a pounding heart, shortness of breath, sweating, and dizziness. Those are also symptoms people associate with cardiac events. Panic also escalates fast, which adds urgency. If you have never experienced panic, “heart attack” can be the most available explanation your brain reaches for.
When should I seek help for panic attacks?
If panic is recurring, if you are changing your life to avoid it, or if you spend a lot of time monitoring your body, it is worth getting support. It is also worth talking to a medical provider if symptoms are new, significantly different from your usual pattern, or if you have risk factors that need to be assessed. Seeking help is not about severity. It is about how much space it is taking up in your week.
Can panic attacks go away on their own?
Some people have a short cluster of panic attacks that resolves when life stress decreases and sleep stabilizes. For others, panic persists because avoidance and safety behaviours keep the brain treating sensations as dangerous. When the pattern is established, it usually improves most when the cycle is addressed directly, not when you wait it out.
