The straight answer: no

The facts: Some people swear by the sauna for detoxing through a good sweating session after a big night of drinking. But experts warn sauna bathing during a hangover could pose real health risks.

In particular, the risk of an orthostatic hypotensive reaction – or in layman’s terms a head rush, whereby a person’s blood pressure falls when suddenly standing up from a lying or sitting position – is increased and associated with fainting and accidents. Further, during a hangover a person’s risk of cardiac arrhythmia – or irregular heartbeat – is raised, and the sauna may further increase this risk.
