"The Myth of Sweating Toxins
Does your yoga instructor tell you that the sweating is good for you because you are releasing toxins from the body? Well, this statement is not 100% true. Most of what you are sweating is water, but there are other chemicals that make up sweat including salt, potassium, ammonia, and urea. True toxin elimination comes from the kidneys and liver, and some from the colon. Doing a ninety-minute hot yoga session and sweating to death is not releasing toxins. You really are just dehydrating yourself and losing only water weight. I hate the burst the bubble, but my statement is true to the facts of body’s biological systems. If you really want to eliminate toxins from the body, it's best to talk to your physician or purchase an over-the-counter liver, kidney, or colon cleanse made out of natural ingredients."4.

"Too hot to handle?
The safety of hot yoga depends on your fitness level and overall health, among other factors. But exercising in extreme heat can lead to dehydration and hyperthermia (elevated body temperature), both of which can cause nausea, dizziness, fainting, muscle cramping, and other symptoms. And if you become very dehydrated and drink too much water afterward without consuming electrolytes, you run the risk of developing hyponatremia (low blood sodium levels), which can also cause such symptoms as nausea and muscle cramping, along with general malaise and even seizures. That’s what happened to a 34-year-old woman who was hospitalized after she did a 90-minute hot yoga workout and then drank 3.5 liters of water, as was reported in the British Medical Journal Case Reports in 2012."
