Children under the age of 6 are generally advised to avoid using saunas due to their bodies' limited ability to regulate heat. For kids aged 6 to 12, sauna sessions should be brief—typically no longer than 5 to 10 minutes—and closely supervised by an adult. It's important to keep the temperature lower than usual, around 110°F to 130°F, to ensure safety. Always encourage children to listen to their bodies and leave the sauna immediately if they feel dizzy, uncomfortable, or overheated. Safety first means keeping sauna sessions fun and chill, not a steam-powered endurance test!
