Agree on the very underrated danger of chlorinated water, whether used for showers, cooking, or drinking.
Hot showers are especially damaging due to the large amounts of chlorinated steam absorbed directly via the lungs.
There is a small book out recently published which details the health damage caused by chronic exposure:

Cyanide Poisoning, Heavy Metals, Liver Poisoning
Sodium thiosulfate is a common dechlorinator used to remove chlorine from drinking water. It is also a well known antidote for cyanide poisoning where the sodium thiosulfate reacts with cyanide to form sodium thiocyanate.
Some people who take too much apricot pits (cancer treatment) have a weak form of cyanide poisoning and found it helpful to add the sodium thiosulfate drops to reduced its side effect when they used the apricot pits, which is high in vitamin B17 or sometimes take apple seeds also somewhat high B17 to treat themselves of cancer or other immunity problems.
They have reported to me that the side effects were reduced from taking too much apricot pits, and caused them to be to nauseated, but when sodium thiosulfate drops are taken, no nausea effects from too much apricot pits is seen. Apparently the extra cyanide, if it were to exist in excess, reacted with sodium thiosulfate to form sodium thiocyanate, where the body can get rid of them quickly, but I also suspect that the sodium thiocyanate may have some antiviral, anti-cancer properties, perhaps only a tiny amount from eating apricot pits and the thiosulfate reduced effect, but its reacted components may have the same properties nonetheless. I would therefore imagine that the thiocyanate is less toxic than the apricot pits but also reduces the side effects by allowing the body to rid of them easier.
For me I used sodium thiosulfate to get rid of certain heavy metals, and accumulation of oxidative chemicals in the liver, as the sodium thiosulfate is a good reducing agent (reduces free radicals), but it is also a laxative in some respects, at least only initially in detoxification.
Most people are not aware that sodium thiosulfate is a common dechlorinator used in fish tanks, drinking water and swimming pool water, and sometimes a low amount of can be found in natural hot springs water, but they do have trace sodium sulfide too, which is why it can used to treat skin problems and some to bathe in it to relieved them of skin problems, rheumatism, although indirectly.
In other cases I used s.t. to help with sleep, as the reducing agent, especially the thiosulfate form of reducing agents helps with the sleep.
A thiosulfate form can form a weak sulfide compound which is also a component that works synergistically with the body's available nitrites to help to small extent anyway in controlling blood pressure or extend its effect for some people who take nitroglycerine tablets to treat both heart problems and high blood pressure. The effect is seen to last longer.
In my personal observation a bicarbonate formula, in alkaline form mixed with a very tiny amount of sodium nitrites works the same way based on my experiment as both the nitrogylcerine and the sodium nitrite degrades to nitric oxide in presence of organic acids. Interestingly, if the body were already suffering the acidosis conditions from lack of bicarbonates, the nitric oxide, which is the major component in controlling the body's blood pressure, does not degrade, and is more effective in killing of microbes, where its waste product, and the microbe itself are rich in organic acid. The sodium nitrite, produced by the body's own glial cells located in the brain, would degrade to nitric oxide, burning the acid forming bacteria, viruses and other microbes, much like burning them alive.
The sodium thiosulfate is also used as a photographic fixer, known as "Hypo" to prevent the chemicals of photgraphs from further getting dark and fix the pictures, much like a preservative, from preventing the pictures to be developed from further chemical oxidation.
I have also used it in the past to help sleep as well as to help concentration in event of ADHD, children's hyperactivity, and temper tantrums, and have worked remarkably well especially when a child of hyperactivity, is used to treat glutamine (amino acid) to help detoxify ammonia, and helped with brain development, is used in combination with sodium thiosulfate to reduced the resultant temporary hyperactivity that resulted from glutamine use. When those are used in combination, I have noted to cause a child to improve in leaps and bounds, which can be used for ADHD, hyperactivity, autism, and even emotional disturbances. For me, I also used s.t. as an anti-depressant and anxiety problems as well. At least for me anyway, the sodium thiosulfate has wide use, because of its unique properties as a reductant agent, it reduces free radicals, and reduces the liver accumulating actions of oxidative chemicals, where it is most dramatic as a treatment for cyanide poisoning. Still its everyday use is seen in fish aquariums and a dechlorinator for both drinking water and in use of swimming pools. In my opinion, people who used public bath cause their body to accumulate excess chlorine, the people who sells chlorine knows how much a human body uptake chlorine, which is quite a bit, but also does damages to the body. As a result, some people, like me for example, might after exposure to too much chlorinated water, will use the sodium thiosulfate solution to rinse by body of excess chlorine and perhaps some drops of sodium thiosulfate taken internally. Chickens and livestocks cannot use chlorinated water to chickens and pigs, as chlorinated water causes stunting of growth in pigs and chickens. At least in the case of chickens drinking water chlorinated in the farm, the biopsy of chicken were shown to have heart disease, and perhaps this line of chlorinated water used can be extended to human use as well. Of course human water, with chlorine and fluorine uses, is quite toxic to animals, and it is part of the many reasons why humans get sick. I imagine that the sodium thiosulfate to have much more wider use in the distant future and I have only begin to touch only just a small part of this, and not just its ability to remove heavy metals, chlorine, toxic compounds, excess cyanide, its anti-anxiety, anti-depressant effect, promotes sleep, is a laxative, used as a skin problems such as eczmea, and many other applications, I simply can't remember. There was one case of a child who reportedly got fat from swimming in a chlorinated water too long (for about a month) as the oxidative effect of chlorine tend to do that, and well at least help reduce those effect and at the very least, reduce being bloated, as the sodium thiosulfate would react with the excess blood chlorine to form a simple trace amounts of saline solution in very minute amounts instead of a more toxic chlorine.
The sodium thiosulfate is also used as a common remedy to reduce the side effects which causes deafness in some people from chemotherapy. But in my opinion, the free radicals also generated during x ray therapies, such as CAT scans can reduced such side effects just the same. I had a friend of mine who got a terrible headaches after getting her teeth x-rayed and took both vitamin C and sodium thiosulfate. Those two things stopped the headaches (and hopefully the radiation damages to her brain) the same day. It's probably the antioxidant effects from both the vitamin C and the sodium thiosulfate.
All this information I am telling is really old information (about 30+ years ago) as I found this out while doing experiments in U.S. high school. Nevertheless, with the trend in dumbing down of U.S. schools, I doubt any high school student today who studied chemistry would be aware of this as they are just too busy cramming for exams instead of doing experiments and make small discoveries for themselves. It was about the same time I think that Bill Gates was also playing computer programming at his own high school, which might be a monopoly program simulation, before becoming the world's largest software house.
