Sauna vs. Steam Room: What Is The Difference?

Before going any further as to which is better for your illness, it’s important to know the mechanics of each environment. When people ask, “is sauna or steam room better when sick” they are usually comparing two very different types of heat therapy.
The Dry Heat of a Sauna
A traditional Finnish sauna is dry-heat, generally in the range from 150° F to 195°F. The humidity is very low (normally less than 20%). This high, dry heat makes the body sweat profusely. If you are arguing over a sauna or steam room for flu symptoms I know that the dry heat can be suffocating if your sinuses are already dried up, but it’s great for relaxing into aching muscles.
The Wet Heat of a Steam Room
A steam room is a lower temperature, typically between 110°F to 120°F, however, 100% humidity. The moist air is produced by a generator that boils water. Many users asking is steam sauna good for cold symptoms prefer this environment, because the warm moist air will help hydrate the mucous membranes, making the phlegm looser and making it easier to breathe.
Is Steam Room Good For a Cold and Cough?

If you are struggling with an upper respiratory infection then at some point you have wondered, “is steam room good for a cold and cough?” The answer is a resounding yes as long as you do not have a fever.
The warm, moist air works the same way as a humidifier or a steam inhalation treatment. Here is how a steam room if you are sick with a cold can help:
- Loosens Mucus: The high humidity helps to thin out the mucus in your throat and lungs, making it easier to get rid of.
- Clears Sinuses: The steam will penetrate the nasal passages, providing relief to the sinus pressure and helping clear the blockages.
- Soothes the Throat: Although dry air causes irritation in a sore throat, moist steam is soothing (unless the heat is too high).
Many people on forums such as Reddit arguing “sauna or steam room for cold Reddit” threads often argue for the steam room simply because it is easier to breathe in a humid environment rather than a dry one if you have a compromised respiratory system.
Sauna or Steam Room for Flu, What’s Best?

When the flu comes along, it brings with it body aches and fatigue. So, who is the winner in the sauna or steam room for flu fight?
The main advantage of sauna for sickness, flu, is the relief of muscles. The high heat in the body causes blood to flow to the skin and muscles, which may relieve the body aches often associated with the flu. Some studies have even suggested that the fake fever which the sauna causes might stimulate the production of white blood cells, which could boost the immune system.
However, the question remains; sauna good for cold and cough or the flu?
While this may assist with aches, the dry sauna or steam room when sick comparison may tend towards steam for respiratory symptoms. Dry heat can dehydrate you at a faster rate, which is dangerous when you are already struggling with an illness.
Important Warning: If you have the flu, and the fever, avoid both. Overheating a body that is already fighting with a fever can cause heat exhaustion or heat stroke.
Sauna or Steam Room for Sore Throat

A sore throat can make swallowing painful and talking difficult. When considering a sauna or steam room for sore throat relief, the steam room is generally the superior choice.
Dry heat in the form of a sauna may actually worsen an already inflamed throat by drying out the mucous membranes further. Conversely, the steam room helps to create moisture that can lubricate the throat and help relieve the scratchiness temporarily.
If you are trying to choose “is it better to sauna or steam room when sick” just based on the comfort of your throat, choose the steam room. Just make sure you are breathing in through your nose because it filters the airflow a little to your throat.

When in the midst of a debate on the topic of “is the sauna or steam room good when your sick,” medical professionals often make reference to the “Neck Check.”
- Above the Neck (Go Easy): If symptoms are “above the neck” – such as runny nose, sneezing, minor sore throat – you can probably go for a steam room or a mild sauna visit. In this case, a question of “what’s better when you’re sick sauna or steam room” usually leads towards the steam room for its decongestant properties.
- Below the Neck (Skip It): If you have chest congestion, upset stomach, body aches or fever skip the heat therapy. These are the systemic symptoms which indicate your body is in need of rest, not stress.
Does Sauna and Steam Room Help a Cold? (The Scientific Perspective)
The question of many users: does sauna and steam room help with a cold” after all, cure the illness? It is important to establish expectations: Heat therapy is symptomatic treatment, not the virus itself.
