What action should individuals with poor health take before using the sauna?

Individuals with poor health should consult a physician before using a sauna to ensure their safety. Saunas can impose substantial physical stress due to high temperatures and humidity, which may exacerbate certain health conditions such as cardiovascular issues or respiratory problems. A physician can assess an individual's medical history and current health status to provide personalized advice regarding the use of saunas.

While taking a medical test may provide insight into someone's health, it does not directly address the immediate concerns about using a sauna. Reading sauna guidelines can offer useful information about the safe use of saunas but does not replace professional medical advice tailored to an individual's specific health situation. Skipping the sauna altogether may seem like a safe choice, but without consultation, a person might miss out on potential benefits or safe practices they can follow while using the sauna. Consulting a physician is the most proactive and informed action to ensure both safety and health.
