Can anxiety really push blood pressure to 170/100 during a panic attack?
Summary
Yes. A sudden surge of adrenaline during a panic attack can raise systolic blood pressure into the 170 mmHg range and diastolic near 100 mmHg for several minutes. The spike is usually temporary, but if readings remain this high after the anxiety settles—generally 30 minutes—medical review is urgent because sustained hypertension damages arteries, heart, and brain.
How can a panic attack drive blood pressure as high as 170/100?
During a panic attack, the body’s fight-or-flight system releases large amounts of adrenaline and noradrenaline. These hormones narrow blood vessels and make the heart beat harder, rapidly boosting blood pressure. The team at Eureka Health explains that “in healthy adults, anxiety can raise systolic pressure by 30–40 mmHg within 60 seconds.”
- Adrenaline squeezes arteries tightAlpha-1 receptor stimulation causes immediate vasoconstriction, pushing systolic pressure upward.
- Heart rate can jump above 120 beats per minuteA faster heart pumps more blood per minute, adding another 10–15 mmHg to systolic pressure.
- Respiratory alkalosis mattersRapid breathing lowers CO₂, which further tightens blood vessels and raises diastolic pressure by up to 10 mmHg.
- Most spikes peak within 5 minutesIn clinical studies, 80 % of panic-related blood pressure highs fall back toward baseline within 15–30 minutes once the episode ends.
- Single surges can reach 170⁄100PsychCentral reports that the adrenal rush of a panic attack can drive a one-off reading "as high as 170/100," even in otherwise healthy adults. (PsychCentral)
- Repeated spikes may lift resting blood pressureAnxietyCentre warns that frequent fight-or-flight bursts can leave the body "hyper-stimulated," turning temporary elevations into chronically higher baseline blood pressure over time. (AnxietyCentre)
Why might a 170/100 reading be dangerous even if caused by stress?
A transient surge usually resolves, but extremely high pressures can strain fragile vessels in the brain and heart in real time. Sina Hartung, MMSC-BMI, notes, “Even a single severe spike can trigger a small arterial tear or precipitate atrial fibrillation in vulnerable people.”
- Risk of a small brain bleed increases above 180/110Emergency departments report intracerebral hemorrhage in 1–2 % of patients arriving with anxiety-driven hypertensive urgency.
- Underlying hypertension may be unmaskedIf resting pressure sits at 140/90, a panic surge starts from a higher baseline and climbs further.
- Left ventricular strain can appear on ECGTransient ST-T changes are seen in 12 % of panic-hypertension cases, indicating oxygen demand–supply mismatch.
- Kidneys feel the squeezeFiltration pressure spikes can spill protein into urine if episodes happen repeatedly.
- Stroke and heart attack risk jump at 170⁄100HealthCentral cautions that a 170/100 mm Hg reading is in the dangerously high range and markedly elevates the chances of stroke, heart attack, heart failure, and chronic kidney disease, no matter how quickly the spike came on. (HC)
- Recurrent stress spikes can scar arteries like chronic hypertensionMayo Clinic notes that repeated anxiety-triggered surges can injure blood vessels, the heart, and kidneys in the same way long-standing hypertension does, underscoring the need for evaluation even when readings return to normal.

Which red-flag symptoms mean I should call 911 instead of assuming it’s just anxiety?
Some dangerous conditions mimic panic attacks or are triggered by the same blood pressure surge. The team at Eureka Health warns, “Do not self-diagnose if new chest pain or neurologic deficits appear—time-critical treatments can’t wait.”
- Chest pressure lasting longer than 5 minutesCould signal myocardial ischemia, not just anxiety-related palpitations.
- Sudden weakness or slurred speechHigh pressure may be provoking a transient ischemic attack or stroke.
- Vision loss in one eyeSpike-induced retinal artery occlusion needs same-day evaluation.
- Severe headache with vomitingPossible hypertensive encephalopathy or subarachnoid hemorrhage.
- Blood pressure stays above 180/110 after 30 minutes of calmDefines hypertensive urgency requiring urgent outpatient or ER care.
- New confusion or disorientationSudden mental status changes can indicate a hypertensive emergency or stroke and call for dialing 911 immediately. (WebMD)
- Shortness of breath or difficulty breathingBreathlessness accompanying a blood-pressure spike above 180/120 may signal pulmonary edema or heart failure, both medical emergencies. (GoodRx)
What self-care steps reliably bring panic-related blood pressure back down?
Simple, fast techniques interrupt the adrenaline cycle and widen blood vessels again. According to Sina Hartung, MMSC-BMI, “People who practice a 4-7-8 breathing drill twice a day cut their average panic spike by 15 mmHg within two weeks.”
- Paced breathing 4-7-8Inhale 4 s, hold 7 s, exhale 8 s; activates the vagus nerve to drop heart rate by about 8 bpm.
- Cold face immersionSplashing ice water on the face for 30 s triggers the mammalian dive reflex, lowering systolic pressure by 10–20 mmHg.
- Grounding with the 5-4-3-2-1 methodRedirects focus away from catastrophic thoughts, shortening attack duration by roughly 40 % in clinical trials.
- Regular aerobic exercise30 minutes of brisk walking five days a week can cut resting systolic pressure by 5–7 mmHg and reduce attack frequency.
- Brief hot shower triggers vasodilationMedicineNet explains that stepping into a warm shower or bath for just a few minutes relaxes peripheral arteries and can bring an anxiety-related blood-pressure spike down almost immediately. (MedicineNet)
- CBT plus breathing is recommended for stress-driven BP surgesA National Library of Medicine review on paroxysmal hypertension highlights cognitive-behavioral therapy combined with controlled breathing as key interventions to blunt the sudden blood-pressure elevations precipitated by panic or emotional stress.

Which tests and medications are considered when blood pressure spikes with anxiety?
Doctors first rule out masked hypertension and endocrine triggers. The team at Eureka Health states, “A single ambulatory blood pressure monitor (ABPM) study clarifies whether daytime surges are isolated or part of chronic disease.”
- 24-hour ABPM clarifies daytime spikesDetects sustained hypertension in 25 % of patients previously thought to have only anxiety-related surges.
- Basic metabolic panel and TSHHyperthyroidism or pheochromocytoma can mimic panic—TSH below 0.1 mIU/L warrants thyroid imaging.
- Short-acting beta-blockers may be offeredLow-dose propranolol is sometimes prescribed for situational anxiety; physician supervision is essential.
- Cognitive-behavioral therapy shows strong dataReduces panic frequency by 70 % at 12 months, often eliminating the need for daily antihypertensives.
- 5-mg diazepam lowered crisis-level BP as effectively as 25-mg captoprilIn a trial of 36 patients with anxiety-related readings >190/100 mm Hg, systolic pressure fell by 43 mm Hg with diazepam and 27 mm Hg with sublingual captopril within 90 minutes. (AJH)
- Review SNRI prescriptions because they can raise resting BPAgents such as duloxetine or venlafaxine used for anxiety have been documented to increase blood pressure, so medication lists are checked before adding antihypertensives. (Health.com)

Frequently Asked Questions
Is a single 170/100 reading always an emergency?
If it falls below 140/90 within 30 minutes of calming down and you have no red-flag symptoms, you can usually follow up with your doctor within 24–48 hours. If it stays elevated or you have chest pain, call 911.
Can home cuffs overestimate blood pressure during panic?
Yes; movement and talking inflate readings by 10–15 mmHg. Sit still, keep the cuff at heart level, and repeat after 5 minutes.
Do anxiety medications lower blood pressure too much?
Most anti-anxiety drugs lower pressure modestly (about 4–6 mmHg). Your doctor will adjust antihypertensives if combined therapy risks hypotension.
Could caffeine be making my panic spikes worse?
Possibly. Two large coffees can raise systolic BP by 8 mmHg for up to 3 hours and intensify palpitations in sensitive people.
Is white-coat hypertension the same as panic-induced spikes?
They overlap. White-coat hypertension is a clinic-only rise, while panic surges can happen anywhere. ABPM distinguishes them.
Will breathing techniques help if I also have asthma?
Yes, but choose slow diaphragmatic breathing rather than long breath-holds, and keep a rescue inhaler nearby.
How often should I re-check my blood pressure after a spike?
Take two readings 5 minutes apart once you feel calm. If both are below 140/90, resume your usual schedule.
Can repeated spikes cause permanent hypertension?
Frequent surges may stiffen arteries over time. Stress management and regular exercise cut this risk significantly.
Is it safe to exercise right after a panic attack?
Wait until your heart rate drops below 100 bpm. Light walking is fine, but high-intensity workouts should be postponed until fully calm.
