Hot tea may raise esophageal cancer risk
According to recent studies, drinking hot liquids, such as tea, over 140 degrees fahrenheit or especially over 142 degrees, increases the risk of esophageal cancer.

But what about sitting in a steam room or sauna and inhaling that hot vapor? Steam rooms typically are high humidity and around 113 degrees, so perhaps that is safe, but saunas are often over 200 degrees albeit at lower humidity.

Perhaps a study should be done of rates of esophageal cancer among frequent sauna bathers, such as in Scandinavia.
