Kids and Sauna - Yea or Nay?

I recently received an interesting press release from KLAFS GmbH & Co. KG that highlighted the benefits of sauna-going for children. According to the release, in Finland, children are brought into the sauna for the first time at the age of one, and healthy children tolerate a short stay in the sauna well. They also point out that it is important that children only stay in the sauna as long as they feel comfortable but that the beneficial aspects of sauna for children are the same as for adults. I'm a huge fan of sauna-going and  incorporating a hot-and-cold circuit that includes multiple stops in the sauna, cold plunge, and a steam to boost my circulation. But I've never seen a child in the sauna, at least in the states. What do you think? Great import idea or not an excellent option for kids?
