We have already talked about extremely high temperature in Finnish sauna or Russian banya steam rooms. It is abt. 180° F and 20-25% average humidity in sauna or abt. 120-140° F and 70-80% average humidity in banya. It is reasonable that in hot atmosphere all of sauna's component parts are very important. Heater, rock and wood are as important as head-backrest, essence oil, bucket and thermometer.
Stones which should be placed all around the heater elements are not to store heat and produce steam when water is poured over them. It's good for a softer, more comfortable bathing experience and it provides better steam.
Using the softwood in sauna or banya steam chambers must absorb humidity into the wood for keeping the bathing atmosphere very soft and pleasant. Since buckets, pails, dippers, thermometers and hygrometers etc. are essential Sauna accessories claim attention too. Sauna accessories from stainless steel, wood and glass also help to transform the hot dry air into a comfortable moist atmosphere. Any plastic parts can mar the pleasure while you are inhaling excellent bath aromas. But aroma is the only and the most important in all of these bath procedures.
There are different means for preparing sauna and Russian banya fresh aromas. We can 'cook' them from natural product by ourselves. I have told about some experience in my previous posts. They are: Calendula aroma, fresh and energetic bath steam with Silver Fir and peppermint. Mustard is the old Oriental secret for sauna or banya; and there are some secrets with beer and absinth to lose weight and get a good mood, some great recipes to cure colds and flu: Australian method with eucalyptus; chamomile herbal extract and the best secret is about how to make a horse radish bath steam.
Moreover we can have sauna fresh aromas with pure essence oil such as: Eucalyptus aroma, Cherry aroma, Dandelion aroma, Citrus Orange aroma, Birch aroma, Lavender aroma, Apple aroma, Citrus aroma, Pine aroma etc. It is usually concentrated and you only need 5 to 10 drops to add to a bucket of water, or just one or two drops to a dipper of water. Pour this scented water slowly over the hot stones and enjoy yourselves.
But all of these secrets and aromas can wane if you do something wrongly.
All of handmade herbal extracts must be filtered out because even small parts of chamomile or horse radish are left they can cause a trouble if they get onto the rock. If accidentally you put some pure oil to the stones you get cinders instead of aroma.
Therefore I attract your attention to sauna's accessories because its incorrect using can make damage instead of restoring one's health. At the same time any trifle such as sauna's felt-cap can bring some pleasure.
