Using the sauna can relieve symptoms of colds?

Scientists recently confirmed the old idea that hot liquids may relieve symptoms of flu and colds. But what about a dose of heat in a much larger scale - say, a sauna?

With temperatures of 80 degrees Celsius or more, the saunas have been recommended for arthritis, asthma, chronic fatigue, among other evils, since they were used by nomads in Finland, centuries ago. Some benefits were not considered popular, but there is evidence that saunas can accelerate the process of recovery from colds and reduce their occurrence.

Some researchers suspect that a sauna relieves symptoms by improving the drainage, while others attach to the high temperatures weaken the power of the flu virus and cold. However, the reason why this may initially prevent the disease is not yet clear. But research suggests some effect.

In a study by Austrian researchers, for example, 50 adults were divided into two groups and monitored for six months. One group was instructed to attend saunas regularly, the other group failed. At the end of the study, the group had contracted the sauna less flu.

"This was seen particularly in the last three months of the study period, when the incidence fell by half, compared to the control group," wrote the scientists.

Other studies showed similar results. However, doctors warn that saunas can be harmful for people with heart or circulatory problems.

In conclusion, there are, rather, evidence that a sauna can reduce or prevent symptoms of cold.
