In general, it is beneficial to cover with a cloak while doing a steam session. Cloak cover is a good way to get a full body detox. A blanket, sheet, towel or robe can be used as a cloak. Plastic is not recommended as it might expose the skin to toxins.
In certain situations, a cloak is unnecessary. If you are in a very hot environment then the cloak is unnecessary. Cloaking is not appropriate if your body is showing signs of excess heat such as hot flashes, night sweats or infections.
