Avoid a sauna if you have a fever of any level, the flu, severe respiratory symptoms, cardiovascular disease, or if you are pregnant without medical clearance.

Final Thoughts

If you feel excessively weak or are dehydrated, skip the session entirely. Saunas work through heat therapy to potentially ease cold and flu symptoms by clearing congestion, supporting immune function, and improving blood flow throughout the body. Both traditional saunas and infrared saunas offer therapeutic benefits that may help people feel better during illness. Despite potential temporary relief, using a sauna while ill, especially with the flu, carries significant risks. Dehydration is a major concern, as the flu causes fluid loss, and intense sweating in a sauna exacerbates this. Heat exposure can raise heart rate and boost fluid losses, which increases dehydration risk and cardiovascular strain during an active cold or flu.

Short rule: avoid a sauna if a fever exists, symptoms are worsening, or there is marked weakness. The warm air and low humidity in a sauna can help open your airways, making it easier to breathe and helping to clear congestion. This can offer temporary relief to the main symptoms of flu such as an irritated throat, stuffy nose and cough.
