Infrared saunas can be a useful adjunctive treatment for lowering blood pressure, but individuals with cardiovascular conditions should use them with caution and under medical supervision. When using an infrared sauna, it's essential to follow certain guidelines to minimize potential risks.
- A typical session should involve 15-30 minutes at temperatures between 120-140°F (49-60°C), starting with shorter sessions and gradually increasing as the body adapts 1.
- For those with hypertension, it's advisable to start with just 5-10 minutes and monitor how the body responds.
- The heat from infrared saunas causes blood vessels to dilate, improving circulation and potentially reducing blood pressure temporarily, as seen in studies on sauna use and its effects on the cardiovascular system 2, 3.
- This vasodilation effect may last for several hours after use, but the sudden temperature change can also cause a drop in blood pressure that might lead to dizziness or fainting.
- It's crucial to stay hydrated before, during, and after sauna use, and to exit the sauna immediately if feeling lightheaded or uncomfortable.
- People taking blood pressure medications should be particularly cautious, as the combination of medication and sauna-induced vasodilation could cause blood pressure to drop too low 4, 5.
- Regular sauna bathing has been associated with reduced risk of hypertension, which may be a mechanism underlying the decreased cardiovascular risk associated with sauna use 4. Always consult with a healthcare provider before using an infrared sauna, especially if you have hypertension, heart disease, or are taking cardiovascular medications.
