Can Migraine Attacks Raise Your Heart Rate?

If you’ve ever noticed your heart pounding, your pulse jumping, or a “revved up” feeling during a migraine, you’re not imagining it. Migraine and heart rate changes can show up together sometimes as palpitations, sometimes as a higher resting heart rate during an attack, and sometimes as a heart-rate spike when you stand up.

Key Takeaways

  • Autonomic symptoms (including heart-rate changes) can occur with migraine.
  • Research using heart-rate variability (HRV) suggests autonomic imbalance may be present in episodic and chronic migraine.
  • In some cases, autonomic dysfunction can trigger migraine symptoms, rather than migraine triggering heart-rate issues.
  • Dehydration/low blood volume can worsen tachycardia and orthostatic symptoms, which may overlap with migraine flares.
  • New, severe, or concerning heart symptoms should be medically evaluated.

One big reason: migraine isn’t only head pain. It often involves the autonomic nervous system, the system that regulates heart rate, blood pressure, sweating, digestion, and more.² Understanding how these systems overlap can help you track patterns, reduce fear, and know when medical evaluation is important.

What “Migraine and Heart Rate” Usually Refers To

People typically mean one (or more) of these patterns:

  • Higher heart rate during an attack: your pulse feels elevated even at rest
  • Palpitations: awareness of heartbeat, fluttering, pounding
  • Shaky/anxious body sensations: even when you don’t feel mentally anxious
  • Heart-rate spikes when standing: sometimes paired with dizziness, weakness, or brain fog

The timing matters. Heart-rate changes during an attack can reflect pain and stress physiology. Heart-rate spikes that show up mainly with standing may point more toward orthostatic intolerance or autonomic dysfunction as a driver.

The Autonomic Nervous System and Migraine

The autonomic nervous system (ANS) has two broad modes:

  • Sympathetic (“fight or flight”): raises heart rate, increases alertness
  • Parasympathetic (“rest and digest”): supports recovery, lowers heart rate

Migraine has long been associated with autonomic symptoms, such as nausea, sweating, temperature changes, nasal congestion, light sensitivity, and sometimes cardiovascular changes.² In other words, autonomic shifts can be part of the migraine package, not a separate issue.

Some research also suggests autonomic differences may be present between attacks, which may help explain why certain people feel more reactive to stress, posture, or hydration changes even on “good days.”²³

Why Heart Rate Can Spike During a Migraine

There isn’t one single cause; heart-rate changes often reflect multiple factors stacking together.

Pain Response and Stress Hormones

Pain is a stress signal. During a migraine, the body can tilt toward sympathetic activation (more “fight or flight”), which can increase heart rate.²

Nausea, Vomiting, and Reduced Intake

Migraine commonly affects appetite and hydration. If you’re eating less, drinking less, or losing fluids through vomiting, your blood volume can drop. That can contribute to a faster heart rate as the body tries to maintain circulation.⁷

Sensory Overload and Physiological “Overdrive”

Bright light, noise, screens, and overstimulation can add nervous system load. When the system is already stressed, the body may respond with a higher pulse and a more reactive baseline.²

HRV and Migraine: What Studies Suggest

Heart-rate variability (HRV) is a measure of how much your heart rate changes from beat to beat. Higher HRV is often associated with greater parasympathetic flexibility, while lower HRV can reflect a more “locked-in” stress response.

Studies comparing people with migraine to controls have reported differences in HRV and other autonomic markers in episodic migraine.³ Research in chronic migraine also suggests patterns consistent with autonomic dysfunction, though results vary and HRV is not diagnostic on its own.⁴

The important takeaway: HRV research supports the idea that migraine can involve autonomic imbalance, helping explain why heart rate, digestion, sweating, and dizziness may be part of someone’s migraine picture.²³⁴

When Autonomic Dysfunction Can Trigger Migraine Symptoms

This is a key nuance: sometimes the sequence is reversed. Instead of “migraine causes heart rate changes,” autonomic dysfunction can trigger migraine symptoms or increase susceptibility.

One example is postural orthostatic tachycardia syndrome (POTS) and related orthostatic intolerance conditions. These are characterized by abnormal heart-rate increases on standing and symptoms like dizziness, fatigue, brain fog, and sometimes headache. A narrative review describes migraine as a common comorbidity in POTS and explores shared autonomic mechanisms.⁵ An American Headache Society research summary also discusses the POTS-migraine relationship and why the overlap matters clinically.⁶

Practical pattern clue:

  • If your heart rate spikes mostly when you stand, and migraine symptoms follow (rather than leading), it may be worth discussing orthostatic intolerance or autonomic dysfunction with a clinician.

The Role of Hydration and Electrolytes in Heart Rate Stability

Hydration status influences blood volume. When blood volume is lower due to dehydration, inadequate sodium intake, heat, sweating, illness, or poor intake, heart rate can increase to compensate, especially when upright.⁷

A clinical review on hydration interventions in orthostatic conditions discusses how increasing fluids and electrolytes can support circulatory stability by improving volume and vascular response.⁷ This doesn’t mean hydration “treats” migraine, but it does support a key piece of physiology that often overlaps with migraine flares: feeling depleted, lightheaded, and tachycardic.

For people who notice migraine symptoms clustering with dehydration, heat, travel, or upright intolerance, hydration strategy (including electrolytes) may be a meaningful variable to track.

A Migraine-Aware Routine for Heart Rate Swings

This is not medical treatment, just a practical approach for pattern tracking and baseline stability:

  • Hydrate early: many people wake up mildly dehydrated after overnight fluid loss.
  • Use micro-sips during high-risk windows: long meetings, travel, heat, sensory overload.
  • Pair fluids with electrolytes on depletion days: especially when sweating, sick, or prone to upright symptoms.⁷
  • Track timing + posture: note when heart rate spikes happen (rest vs standing), what preceded it (stress, caffeine, missed meals), and whether migraine symptoms follow.

Tracking helps you and your provider answer the most important question: Is the heart-rate shift primarily a migraine-phase symptom, or is autonomic dysfunction a trigger that’s raising migraine risk?⁵⁶

How Rescue Drops Fit Into Migraine and Heart Rate Support

If you notice that heart-rate swings and migraine symptoms overlap most on depleted days that include heat, sweating, illness, long travel, or flare-prone weeks, supporting hydration and electrolytes can be a practical part of your routine.

Rescue Drops are Buoy’s most concentrated electrolyte formula, designed for intense depletion and rapid recovery. They’re positioned to support hydration when you’re particularly depleted by providing a higher-sodium electrolyte profile alongside additional electrolytes and trace minerals.

This is not a treatment for migraine or autonomic disorders, but it can be a convenient way to support hydration and electrolyte balance when you’re working to restore a steadier baseline.

When to Talk to a Doctor

Because heart-rate symptoms can have many causes, seek medical evaluation if you experience:

  • New or worsening palpitations
  • Chest pain, fainting, severe shortness of breath
  • Persistent dizziness or heart-rate spikes with standing
  • Major changes in migraine pattern with neurological symptoms

If your symptoms strongly cluster around standing (tachycardia + dizziness/brain fog), ask your clinician about evaluating orthostatic intolerance or autonomic dysfunction.⁵⁶

Support a Steadier Baseline When Migraine and Heart Rate Collide

Migraine and heart rate changes often share a common thread: the autonomic nervous system. For some people, the heart-rate shift is part of the migraine phase; for others, autonomic dysfunction may be the trigger that pushes the system toward migraine symptoms. Tracking timing, posture, and hydration patterns can help clarify what’s happening. On depleted days, consistent fluids and electrolyte support, such as Rescue Drops, may help you feel more stable as part of a migraine-aware routine.
