Think you can "sweat out" the alcohol and other toxins you may have consumed during a night of partying? Think again.

Researchers from the Finnish State Alcohol Company's Research Laboratories, in Helsinki, warn that sauna bathing while hung over carries "real health risks," including dangerous drops in blood pressure and abnormal heart rhythms.
