#Chlorination of drinking water is statistically associated with #cancer (bladder, colorectal). On the other hand it has reduced waterborne infections. Fortunately, there are ways out of this dilemma. https://www.theguardian.com/us-news/2025/feb/17/water-chlorination-cancer-risk-us-eu
Water chlorination levels in US and EU likely increase cancer risk, study finds

Bladder cancer risk increased 33% and colorectal cancer by 15% in using chlorine to disinfect water

@Daniel_Hoffmann Thanks for boosting this @TalktoBeverley
Oddly I was only wondering a few days ago, whether there could be a link between my chlorine sensitivity and other illnesses. I can't go anywhere near a chlorinated swimming pool anymore. I do wonder whether drinking water chlorination might cause other conditions too.

Oh, I do hope it helps solve a few issues for you Lee, though obviously I'm sorry you have these conditions.

I can't quite recall how I came across @Daniel_Hoffmann but definitely worth a 'follow'. I think someone else I follow boosted something of his...

Wishing you well.

@TalktoBeverley @Daniel_Hoffmann Getting the NHS to take things like this seriously is always a challenge. If it doesn't give you anaphylactic shock, they rarely want to investigate further. I don't get the distinction they make between allergies and sensitivities, both cause unpleasant symptoms/reactions that can often be quite disabling.

@LJClements8 @Daniel_Hoffmann

I need to look into this. I'd never considered the difference between allergies and sensitivities.

A family member has a range of peculiar symptoms and I can't get anyone to take their situation seriously. I've suggested dysautonomia to our GP but beyond wearing a heart monitor for a day and finding nothing, that's been the end of it.

I'm banging my head against a brick wall. They're not exactly in immediate danger, but their life is miserable at times.

@TalktoBeverley @LJClements8 @Daniel_Hoffmann An allergy is always an immune (over-)reaction. Sensitivity is broader and can but doesn't need to involve immune responses. For instance, if I had a defect in a gene for an enzyme that removes a product of a normal biochemical reaction, that product will accumulate and eventually become a problem. In that case I would be sensitive to that product.

@Daniel_Hoffmann @LJClements8

Daniel, thank you for taking the time to explain. I appreciate the interaction.

In relation to my family member, they have so many symptoms it's really difficult to disentangle them. Web searches can be helpful, but often create more questions than answers, especially for a lay person.
