Tap‐water iontophoresis (TWI) using direct current (DC) is considered by some to be the most effective therapy in palmoplantar hyperhidrosis, although it is debated that botulinum toxin injections may be better (Wade, et al. 2018).
How does TWI block sweat glands, and what are the side effects?
The mechanism of action is unknown. It is hypothesised that an ...
Sweat contains a concentration of salt:
Sweat is mostly water. A microfluidic model of the eccrine sweat gland provides details on what solutes partition into sweat, their mechanisms of partitioning, and their fluidic transport to the skin surface. Dissolved in the water are trace amounts of minerals, lactic acid, and urea. Although the ...
What you are describing is most likely hyperhidrosis, a disorder that causes excessive sweating. It This sweating usually occurs on the underarms (axillary) or the palms of the hands and soles of the feet (palmoplantar).
There is also another type of classification for hyperhidrosis. Primary hyperhidrosis (more common) is excessive sweating not related to ...
The generally accepted medical wisdom seems to be that sweat is an insignificant mechanism for toxin elimination. However, there have been studies that suggest that wisdom may not be entirely correct.
For example, Genuis et al. found that some toxic elements were preferentially excreted in sweat, including elements that were not found in blood serum. That ...
There are a number of possibilities, from benign to serious.
Sweating is under the control of the sympathetic nervous system, as is vasodilation (facial redness). Anhydrosis of only one side of the face would be due dysfunction of the trigeminal nerve (which also carries sensory and motor components) on that side of the face. The trigeminal nerve can lose ...
Head sweating and flushing after eating or just smelling or thinking about a certain food is called gustatory sweating.
Gustatory sweating: Sweating on the forehead, face, scalp, and neck
occurring soon after ingesting food. Some gustatory sweating is normal
after eating hot, spicy foods. Otherwise, gustatory sweating is most
After some more research it looks like the answers to these questions are indeed still unknown. A recent 2018 article on Proposed mechanism of action of tap water iontophoresis for treatment of hyperhidrosis summarizes:
Tap water iontophoresis is commonly used to treat hyperhidrosis, yet the mechanism of action for this treatment remains unknown.
While official government recommendations seem to indicate a very low risk:
Toxicological Risks of Selected Flame-Retardant Chemicals. (National Research Council (US) Subcommittee on Flame-Retardant Chemicals.

According to this article: http://www.huffingtonpost.com/melissa-edmonds/does-sweating-release-tox_b_8372452.html, just sweating has no clear health benefits.
The health benefits of sweating come with exercise.
Salvia is a herbal treatment with a long tradition for this indication.
The HMPC has classified sage leaves as a traditional herbal medicinal product.
ESCOP: internally for increased secretion of sweat; externally for inflammation of the mucous membrane of the mouth and throat, gum inflammation.
Commission E: internally for dyspeptic ...
What matters is the so-called wet-bulb temperature :
The wet-bulb temperature is the temperature read by a thermometer covered in water-soaked cloth (wet-bulb thermometer) over which air is passed.
If the wet-bulb temperature exceeds 35 C, then that's going to be fatal on the long run, as the human body can then no longer dump all the heat it produces ...
Getting dizzy and collapse in the sauna or during running is not enough to say that this is from heat exhaustion. Such symptoms can also occur in vasovagal syncope due to heat and the associated stress resulting in a drop in the blood pressure.
Symptoms of vasovagal syncope and heat exhaustion can be very similar (dizziness, pale and clammy skin), but in ...
This is much easier to measure than to calculate.
After urinating and before going to bed, weigh yourself. After getting up, urinating and having a bowel movement (bm is mostly water) weigh yourself in the same clothes. The difference in weight is mainly due to water loss (urine loss, sweating and insensible perspiration); this will be likely ~0.5 kg or ...
