Wearing a sauna suit does not act as a detox

Let’s get this straight. There’s no such thing as a detox. Yes, there are toxins and these are produced in our body, but we deal with these things pretty well. We certainly do not detox via sweat. 

Sweat is used to control body temperature via evaporative heat loss. It’s comprised of:

  • Water (99%)
  • Some electrolytes (sodium, chloride, potassium) 
  • Urea
  • Lactate

It’s worth mentioning that sweat is hypotonic compared to blood plasma. If it’s hypotonic that means it’s ‘less concentrated’ than blood. If sweat was used to detox then it would be hypertonic since toxins would be present in sweat. 

There’s also no evidence to suggest that wearing a sauna suit benefits immune function.
