I agree with Clare. I would be very careful to overdo any mercury detox/chelation when you still have mercury in your teeth. There is the chance that the heat itself might encourage further vaporising from your amalgams and you could be breathing this back in. It might not be so, but it's a possibility (just as with drinking hot fluids). Sweating is great, don't get me wrong, but the heat from these things, you can see the chances of more vapor coming off the fillings (I could be wrong though). Certainly regardless of amalgams or not, the sauna will encourage mercury through your pores, so you will notice worsening of symptoms. Also you can re-absorb some of it anytime you try and eliminate it. It's one of those things.

A good thing to do at this time is support for your entire body by diet and supplements. This provides the foundation for your body to cope easier, heal, detox better and after the amalgams removed, you should be able to then begin detoxing mercury more with sauna's and other things.

I don't know if you're on a candida diet, but I would highly recommend you do this as I always mention to people that diet can ruin more recoveries than anything else. Sometimes one doesn't have much choice but to go on a good healthy candida diet. No sugar, no yeast, no gluten grains, no milk, no fruit, no potatoes. This allows the yeast/bacteria in your body to reduce because it needs these things to feed off and remain at high levels.

Most people with mercury toxicity have candida. They often need to do this in order to reduce it and cope easier. EAting things like meat, eggs, vegetables, some raw nuts (brazil, almonds), acidophilus plain sugar free yoghurt, etc. and eating good healthy fats like butter, extra virgin olive oils, virgin coconut oil, etc.

Just some advice that might help your body with mercury and to prepare it for the removal. Supplemetns that are good are vitamin C, vitamin E, vitamin B complex, magnesium, zinc, milk thistle, and purified mercury free fish oil (good brands are nordic or blue ice).

As for the sauna, I don't know enough to say it's safe with amalgams still in. Perhaps it might be ok, but I'd not overdo it. Even wtihout amalgams, you have to be careful not to do more than your body can handle. Anytime you encourage mercury detox, it causes a systemic reaction as it's being moved around, some can come out, the rest gets reabsorbed again until the next bout of detox.
