In general, it is beneficial to cover with a cloak during a steam session.
Cloaking is a good way to stay warm while steaming and encourage a full body detox.
A blanket, towel or robe can be used as a cloak.
Cloaking with a plastic material is not recommended as it might expose the skin to toxins.
If you are in a very hot environment or showing signs of excess heat such as hot flashes, night sweats or infections, then cloaking is not recommended.
