Sweat Houses were very common in old times. They were used to cure Rheumatism and Penumonia and other diseases.
The house was small and the walls were made of mud the roof was tatched [sic] with rushes. There was a small door leading into the house.
A big fire was lighted in the house and it was well heated. When the fire was dead and the house heated the person was put into the house and was left there as long as he was able to bear the heat. The door was closed and the house was airtight.
The ruins of an old sweat house can be seen in a field of Joe Mulvey's in the townland of Murhaun. This story was related to me
