Recent research highlights both the health benefits and risks of sitting in a hot sauna:
- Benefits:
- Sauna therapy can improve cardiovascular health, reduce risks of dementia and Alzheimer’s disease, and enhance vascular function. Regular sauna use is linked to lower morbidity and mortality rates and may be beneficial for conditions like flu, headache, and arthritis (Sandell & Davies, 2023).
- Repeated sauna exposure can lead to improvements in bone and muscle mass, indicating potential benefits for physical fitness and strength (Toro et al., 2021).
- Sauna use has been associated with reduced aortic and carotid artery stiffness, which is beneficial for cardiovascular health (Nguyen et al., 2021).
- Risks:
- Excessive heat exposure in saunas can increase the risk of cardiovascular events, especially in individuals with compromised cardiovascular systems. When core body temperature exceeds 1.5°C, cerebral blood flow may be reduced, posing a risk to brain health (Raven & Romero, 2020).
- Saunas can challenge cardiovascular homeostasis, potentially posing risks to individuals with certain health conditions. The mode of heating in saunas can influence cerebral blood flow and intracranial pressure, which may have implications for brain health (Gibbons et al., 2021).
Conclusion: Sauna therapy offers various health benefits, particularly for cardiovascular and cognitive health. However, it is important to consider individual health conditions and monitor sauna duration and temperature to avoid potential risks, especially for those with cardiovascular concerns.
