Really? Sitting in a Sauna Can Relieve Cold Symptoms

Rate This

Scientists recently confirmed the age-old notion that hot liquids can relieve some cold and flu symptoms. But what about a dose of heat on a much larger scale — say, in a sauna?

With temperatures of 176 Fahrenheit or greater, saunas have been recommended for arthritis, asthma and chronic fatigue, among other things, since they were used by nomads in Finland centuries ago. Some reputed benefits have not been examined, but there is evidence that saunas may speed recovery from colds and reduce their occurrence.
