From the Research
Yes, sauna and cold plunge use can potentially exacerbate premature ventricular contractions (PVCs) due to the extreme temperature changes that can trigger or worsen PVCs in susceptible individuals. The underlying mechanism relates to how temperature extremes affect autonomic nervous system function, electrolyte balance, and cardiac electrical conduction, all of which can influence PVC frequency 1. Saunas cause vasodilation and increased heart rate, while cold plunges prompt vasoconstriction and can trigger a vagal response - both of these rapid cardiovascular changes may serve as triggers for PVCs.
Key Considerations
- People with existing heart conditions or frequent PVCs should be particularly cautious when using saunas or cold plunges.
- If you experience palpitations, dizziness, chest pain, or shortness of breath during these activities, exit immediately and seek medical attention.
- Before incorporating sauna or cold plunge therapy into your routine, consult with your cardiologist, especially if you have diagnosed PVCs or other cardiac conditions.
- They may recommend avoiding extreme temperatures, limiting exposure time, or gradually acclimating to temperature changes to minimize cardiac stress.
Clinical Evidence
The most recent and highest quality study on PVCs, published in 2024, highlights the importance of evaluating and managing PVCs to prevent cardiomyopathy and other adverse outcomes 2. Another study published in 2020 emphasizes the need for individualized treatment approaches, considering factors such as PVC frequency, symptoms, and underlying heart disease 1.
Recommendations
- Consult with a cardiologist before using sauna or cold plunge therapy, especially if you have diagnosed PVCs or other cardiac conditions.
- Monitor your heart rate and symptoms during these activities, and exit immediately if you experience any adverse effects.
- Consider alternative therapies or modifications to minimize cardiac stress, such as avoiding extreme temperatures or limiting exposure time.
