Why do they happen?
The drop in oestrogens affects the autonomic nervous system that regulates the heart. Hormonal changes alter the balance between the sympathetic and parasympathetic nerves, causing episodes of tachycardia or irregular heartbeats — especially during hot flashes and night sweats.
Associated symptoms
- Sudden rapid or irregular heartbeat
- Sensation of "fluttering" or thumping in the chest
- Frequently coincide with hot flash episodes
- Greater intensity when lying down or at rest
- Associated anxiety or restlessness
Scientific evidence
Magnesium bisglycinate (400 mg/day) regulates cardiac electrical conduction and reduces the frequency and intensity of palpitations related to hormonal stress by 38% according to controlled clinical studies.
Recommended habits
- Reduce caffeine, alcohol and refined sugars — main triggers
- 4-7-8 breathing to activate the vagus nerve during an episode
- Magnesium + vitamin B6 taken before bed
- Moderate, regular physical activity — improves heart rate variability
- Consult a doctor if episodes are very frequent or accompanied by pain
