After cooling down from the first bath, one goes back into the hot room and begins the cycle again. The number and duration of hot room-cooling down cycles varies from person to person based on personal preference. Usually one takes at least two or three cycles, lasting between 30 minutes to two hours. In Finland's numerous summer cottages bathing might go on well into the night. This is especially true in the summer when there's virtually no darkness at night. The sauna session itself is finished off with a thorough wash.
