Heart palpitations are a conscious perception of heartbeats, felt as an acceleration, irregularity or “skipped beat.” While often benign, they can be anxiety-inducing and affect quality of life. Identifying their cause and adopting the right natural approaches allows reducing them significantly in the majority of cases.
Understanding Heart Palpitations and Their Causes
Palpitations do not necessarily correspond to a cardiac disorder. In approximately 85% of cases, a normal cardiac work-up confirms they are functional, meaning related to extra-cardiac factors.
Stress and anxiety: this is the most frequent cause. The sympathetic nervous system (stress response) accelerates heart rate and can trigger extrasystoles (premature beats) perceived as “skips” or “jumps.”
Stimulants: caffeine (coffee, tea, energy drinks), theobromine (chocolate) and nicotine directly increase cardiac excitability in a dose-dependent manner. One extra coffee when tired is often sufficient to trigger an episode.
Fatigue and lack of sleep: sleep deprivation activates the sympathetic nervous system and increases cortisol, two factors favoring palpitations.
Electrolyte imbalances: magnesium, potassium or calcium deficiency disrupts cardiac electrical conduction at the cellular level. This is one of the most under-diagnosed causes of benign palpitations.
Hypoglycemia: a drop in blood glucose (after a skipped meal, intense exercise, or in hypoglycemia-prone individuals) triggers adrenaline secretion that manifests as palpitations, tremors and perspiration.
Menopause and hormonal fluctuations: estrogen variations in perimenopause are associated with functional palpitations in about 25% of women.
Breathing Techniques to Stop Palpitations Quickly
Two breathing techniques have demonstrated effectiveness in rapidly reducing stress-related palpitations.
Heart Coherence
Heart coherence is a technique for regulating the autonomic nervous system through breathing. It involves breathing at a rate of 5 cycles per minute (6 seconds inhale, 6 seconds exhale), which synchronizes heart rate with the breathing cycle and activates the parasympathetic system (heart brake).
A 5-minute heart coherence session reduces heart rate by 8 to 15 beats per minute on average and decreases salivary cortisol. Practiced 3 times daily (morning, noon and evening), it produces cumulative effects on heart rate variability (HRV) after 4 to 6 weeks.
4-7-8 Breathing
This technique, from Ayurvedic integrative medicine, involves inhaling for 4 seconds, holding the breath for 7 seconds, then slowly exhaling for 8 seconds. This long inspiratory/expiratory ratio powerfully activates the vagus nerve and parasympathetic system. It is particularly effective during an acute episode of anxiety-related palpitations.
Essential oils for stress and anxiety, used by inhalation during these breathing exercises, can potentiate the anxiolytic effect. True lavender and neroli are the most studied for their action on the autonomic nervous system.
Magnesium: A Key Mineral Against Palpitations
Magnesium is one of the most studied minerals in managing benign arrhythmias. Its mechanism of action is direct: it regulates ionic channels in cardiac cells (sodium and calcium channels) and stabilizes their membrane potential. Magnesium deficiency increases cardiac excitability and promotes extrasystoles.
Epidemiological studies estimate that between 60 and 75% of the French population has magnesium intake below recommended levels (420 mg/day for men, 360 mg/day for women). The causes of this widespread deficit are multiple: soil depletion, processed foods, chronic stress (which increases urinary magnesium elimination).
Bioavailable forms: magnesium bisglycinate and magnesium malate are the best tolerated and best absorbed forms. Magnesium oxide, often used in inexpensive formulas, is poorly absorbed and laxative at therapeutic doses.
Dosage: 300 to 400 mg/day of elemental magnesium, taken in two doses with food, for 6 to 8 weeks. Improvement in palpitations is generally observed after 3 to 4 weeks.
Magnesium-rich foods: raw cocoa (>200 mg/100g), almonds (270 mg/100g), pumpkin seeds (550 mg/100g), legumes, buckwheat.
Hawthorn and Gemmotherapy for Heart Rhythm
Hawthorn (Crataegus monogyna, C. laevigata) is the best documented cardiovascular plant in European phytotherapy. It acts at two levels: cardiac rhythm regulation (mild antiarrhythmic properties) and improvement of coronary perfusion.
In gemmotherapy, hawthorn bud macerate is used for functional rhythm disorders combining palpitations, anxiety and mildly elevated blood pressure. The active ingredients in the bud (proanthocyanidins, flavonoids, vitexin) are present at higher concentration than in the leaves and flowers used in classical phytotherapy.
Gemmotherapy and its applications for the cardiovascular system details the protocols for using buds in practice.
Lemon balm (Melissa officinalis) is an interesting complement to hawthorn for predominantly anxious palpitations. It combines anxiolytic properties (mild GABA-A receptor inhibition) and antispasmodic action on smooth muscle.
To improve sleep quality, often disturbed by anxious palpitations, the best herbal teas for sleep suggest documented plant combinations (valerian, passionflower, hops) that also act on overall nervous tone.
Lifestyle: Reducing Palpitations Daily
Several simple lifestyle modifications reduce the frequency and intensity of functional palpitations.
Reduce stimulants: decrease coffee consumption to 1 to 2 cups per day (or switch to decaffeinated), limit black tea and energy drinks, avoid dark chocolate in the evening.
Stabilize blood glucose: space meals, do not skip breakfast, avoid isolated fast sugars. Stable blood glucose reduces reflex adrenaline spikes.
Practice regular physical activity: paradoxically, regular aerobic activity reduces functional palpitation frequency long-term, even if it sometimes triggers them short-term in deconditioned individuals.
Limit alcohol: alcohol, even in moderate quantities, can trigger episodes of atrial fibrillation (AF) in predisposed individuals (the “holiday heart” phenomenon). Regular consumption increases heart rate and disrupts sleep.
Natural techniques for relieving a migraine without medication also include approaches for stress management and autonomic nervous system regulation that are relevant for anxiety-related palpitations.
When Should Palpitations Be a Warning Sign?
While functional palpitations are benign and manageable with natural approaches, certain signs require urgent medical consultation.
Seek immediate care for palpitations accompanied by chest pain or pressure, shortness of breath at rest, dizziness or faintness, brief loss of consciousness, or palpitations occurring after intense physical effort.
A resting electrocardiogram (ECG) and blood panel (CBC, TSH, serum electrolytes including magnesium) allow ruling out organic causes (rhythm disorders, thyroid dysfunction, anemia, severe electrolyte imbalances).
Regular palpitations in a person with family history of sudden cardiac death, known cardiomyopathy or multiple cardiovascular risk factors should be evaluated by a cardiologist.
Frequently Asked Questions
How to stop palpitations quickly?
The fastest and best documented method is the vagal maneuver: breathe deeply, hold the breath and press gently on the abdomen (Valsalva maneuver), or plunge the face into cold water for 15 seconds. Heart coherence (5 breaths per minute for 3 to 5 minutes) is effective for stress-related palpitations within minutes. If palpitations are accompanied by chest pain, shortness of breath or faintness, call emergency services immediately.
What are traditional remedies to calm palpitations?
Lemon balm, passionflower and valerian herbal teas are the most commonly used traditional remedies for stress and anxiety-related palpitations. Lemon balm has documented anxiolytic and mildly antispasmodic properties. Hawthorn, as a herbal tea or bud macerate, is the traditional reference remedy for heart rhythm. Magnesium in the form of magnesium salt foot baths or magnesium-rich mineral water is also used.
Why do palpitations occur during menopause?
Palpitations are a common symptom of menopause, affecting about 25% of women in perimenopause. They are linked to the drop in estrogens, which modifies autonomic nervous system regulation and increases sensitivity to cardiac stimuli. Hot flashes are often accompanied by palpitations. Stress management and sleep optimization are the first recommended approaches.
Does magnesium help with palpitations?
Yes, in the context of magnesium deficiency, which is common. Magnesium is a natural calcium antagonist and regulates cardiac cell excitability. Deficiency promotes minor arrhythmias including extrasystoles and palpitations. Bisglycinate or magnesium malate supplementation (300 to 400 mg/day) for 4 to 8 weeks can significantly reduce palpitation frequency in deficient individuals.
