The Science Behind the Benefits of Steam Showers

You may remember your mother telling you to take a hot shower or bath whenever you got sick. It turns out that these motherly words of wisdom may have substance based on studies suggesting that soothing steam may be an effective means of treating cold symptoms, especially a runny nose.

Studies have demonstrated that soothing steam is an effective means of treating cold symptoms, especially a runny nose.

An experiment performed by the Medical Research Council Common Cold Unit at Harvard Hospital tested whether cold sufferers who inhaled fully humidified, warm air would feel relief from their symptoms. 

The Experiment: Does steam make you feel better when you have a cold?

In one version of the experiment, people who already had the common cold used special machines to inhale warm fully humidified air at either 109F or 86F. The objective was to determine whether warm air made any difference in the severity of cold symptoms.

In a second version, brave volunteers were inoculated with the common cold virus and likewise breathed warm humid air at the two different temperatures from the machine. In this case, the objective was to determine whether warm humid air reduced the severity of the onset of symptoms.

The Results: Steam is a Good Home Remedy for Colds

No matter what temperature the warm air, many cold sufferers reported feeling better after inhaling it. There were differences, however, depending on the temperature of the humid air.

Already Sick - Steam MAY Cut Sick Days in Half

For those people who were already sick, a 20 minute session of breathing in 109F humidified air halved symptoms in the succeeding days compared with those who breathed in 86F humidified air.

Not Yet Sick - Steam MAY Lessen Symptoms

For the people inoculated with the common cold, three 30 minute sessions lessened symptoms for 32 percent of people inhaling 86F humidified air and for 93 percent of people inhaling 109F humidified air.

The conclusion, then, was that breathing in warm, humid air reduced the severity of cold symptoms such as nasal congestion and irritation. Benefits increased with temperature.

The Benefits steam can help lessen symptoms of the common cold by up to 90% of Steam Showers

These results seem applicable to steam showers, in which users also breathe in warm, humid air for a recommended 20 minute session. Dating back centuries to the Bronze Age, before modern medical studies supported steam’s physical benefits, people across the planet flocked to steam rooms —from the “Sudatorium” of the Romans, to the “Banya” steam baths of northern Russia.

But what causes these steam bath benefits? Dr. Reinhard R. Bergel of the University of Munich’s Institute of Medical Balneology and Climatology attributes the “physiologic changes that occur during the bath” to “the rise in body temperature [of the bather] and in part to the influence of the reflexes of the hormonal and nervous systems, which attempt to increase the heat loss [to cool the body down]”

Thus, the hyperthermia, or higher body temperature, combined with the body’s efforts to cool down, is responsible for the potential wellness benefits of a steam bath. It’s even believed that heat causes mechanical changes on the cellular level that may alleviate symptoms for cold sufferers.

According to Dr. Bergel, the moist heat of a steam shower can relieve the following conditions:

  • Bronchial discomfort
  • Catarrh of the upper respiratory tract
  • Coughs
  • Hoarseness
  • Expectoration (coughing up phlegm)

Using Steam Properly

To fully reap these health and wellness benefits of steam, Dr. Bergel recommends the following best practices.

  • Take a regular shower first.
  • Operate the steam shower at a temperature ranging from 110○  to 116 (Recall that this is right around the temperature that the participants of the Harvard Hospital experiment found most beneficial for their cold symptom relief).
  • Stay in the steam shower no longer than 20 minutes (Again, recall that many Harvard experiment participants found cold symptom relief after 20 minutes).
  • When you’re finished, cool off gradually using cool, fresh air and water.
