Can children under the age of 5 make use of the saunas?Updated a day ago

Sauna use isn't appropriate for infants; we advise against use under age 6. Under age six, avoid sauna use. For kids older than age six, the best rule of thumb for session length is one minute per year of age, with adult supervision and provider approval. 

The only real danger here is overuse, such that the user’s body is dangerously overheated (heat stroke risk). In a sauna, you want to induce a hyperthermic state, so we heat up the internal temperature a few degrees for a period of minutes but never beyond 102°F (38°C) core body temp. The hazard is that kids over six years old have a higher surface-to-volume ratio than adult bodies, so they heat up much faster. Therefore, their session should have constant supervision with duration accordingly limited by their age.
