Chlorine: how to get rid of the smell and the taste?


source, author, license

PROBLEM: Chlorine in tap water is NOT safe!

a toxic, irritant, pale green gas. (Symbol: Cl)

The gas was used as a poison gas in the First World War.

Chlorine is added to water supplies as a disinfectant.

Refs: Oxford Dictionary of English

What makes the smell so unbearable?
When chlorine in water met organic substances like it does when running through all surface water source (82% of water is from surface water in Ireland), it produces what is called THM or Trihalomethanes which are harmful disinfection byproducts (DPB), one of them is Chloroform which was used to knock off people at the hospital before an operation.

Chlorine World War I Ypres


Ok, looks like it's not that healthy!

Chlorine has been used as a weapon by germans troop during World War I at Ypres and this is a very deadly weapon now used in the bathroom.

Chlorine is added to tap water because it's killing bacterias, germs, microbes which would be harmful to some of us. However this is not as simple as killing the 'bad' bacteria and all is solved, read on.

Why do they use this product and not another method? Because IT'S CHEAP!

But is it really cheap? Well no, because I've a secret to reveal you: your gut is composed of trillions bacterias and those bacterias are obviously good for you, as without you can't live: they are there to produce 80% of your neurotransmitters, digest food, produce vitamins, and they are more numerous than your total number of cells! They are thus important, needed and to be cared for, this is your microbiome.

What does chlorine do to your microbiome? Well Chlorine being a toxin killing bacterias, viruses, it contributes to killing them in your gut by attacking your microbiome, which causes lots of health issues described lower.

If you're into natural health, you've learnt about probiotics, and if you're not you've learnt about antibiotics. So probiotics repopulate your gut with healthy bacterias (not too much is not better), and antibiotics are designed to kill most bacterias living in your gut, it kills viruses and fungus too so it's carpet bombing: antibiotics destroy your gut bacterias, all your viruses, and fungus, good and bad, so it don't bring back balance.

Chlorine has good sides, but it's harmful to your health: it's not selective, it kills all bacterias, all virus, not what you need for good health. It's not a balanced approach for disinfection.

Effects of Chlorine on Hair

Chlorine strips your hair of its natural oil making them dry, dull and brittle: lifeless.

Effect of chlorine on your skin

To not shock you with photos of redness, itching, eczema, and rashes and other horrible to see photos, which are produced by showering and bathing with chlorine, let's just say that: 

*warm shower or bathing filled with hot chlorinated water, one inhales chloroform: the same product which was used in hospitals to make people asleep before a surgical operation.
*Worse, warm water causes the skin to act like a sponge so one will absorb and inhale more chlorine in a ten-minute shower than by drinking eight glasses of the same water.
*This irritates the eyes, the sinuses, throat, skin and lungs, dries the hair and scalp, worsening dandruff.
*chlorine can also weaken immunity
*chlorine is aging you: it brings in free radicals which are killing your cells.

Drinking chlorinated water causes proven health issues:


The mortality rates of illnesses of all types, and in particular tuberculosis, cardio-vascular disorders and cancers, are directly linked to the quality of the water delivered to the concerned populations.
They increase, in particular, when this water is very mineralised (High TDS >50PPM, Dublin Water TDS=360PPM, London Water TDS=200PPM) and made artificially drinkable after physical treatments and the addition of oxidizing chemical products (Chlorine, Fluoride). - Louis-Claude Vincent

Before listing the health issues, let's talk about the doses to get there.
To give a picture of how minute amount of chlorine is enough to be harmful, let's define the units using two very simple to understand notions, liter and drop.
We talk in liter and drops of water.

1 Liter L = 15419 drops
1 ppm = 15.4 drops per liter
ppm stands for part per million = 1 ml / liter or 10^-6

*0.02 to 3.5 ppm = 0 to 54 drops / L : threshold of smell detection. Causes nose irritation, a weak cough or a dryness of the throat.
*1 to 2 ppm = 15 to 31 drops / L : strong cough, headache, breathing difficulties
*2 to 3 ppm = 30 to 46 drops / L : irritations of mucous membrane
*3 à 4 ppm = 46 to 67 drops / L : burning feeling of skin and nose, becoming unbearable after few minutes

Note that the WHO reference value given for sanitation by chlorine is 5 ppm / L > FAR BIGGER THAN the smallest 0.02 ppm
WHICH MEANS Health issues are guaranteed.

***Documented health issues increase coming from chlorine in tap water:


A few of those studies:

I'm confused: some studies say no issue with chlorine, some says health issues with chlorine, what's the truth?

The first think to do is to stop reading lots of studies filled with jargon and complex vocabulary and look at the facts from an historical perspective: Chlorine has been used as a weapon during World War I, then used as a disinfectant for tap water... If it kills bacterias and your gut contains trillions of bacteria, wouldn't it be logic that it causes issues there? Why studies are contradictory? Because researchers along time have different tools and different methods to assess a situation, they have a different magnifying factor to see things and they look at reality from different angles, so with time the perspective on a problem changes.

Also with time the people tested change: when Chlorine was first used for water, it was a new substance into the water, people were stronger as they had a richer food intake with more vitality and nutrients. People habits change too: are we eating today the same as we were eating 20 years ago? Are we eating the same way? Studies let you believe that for the duration of the study the people were mechanically doing all the time the same thing, do you believe that? People have emotions, aren't those also altering the way they react to what they eat? Of course they do.

From a chemical point of view: DPB / THM are bioaccumulative, which means the effect on your health may not materialize straight away, but on the long run they do. Also when a study is done, people are exposed to a certain environment and with chemical pollution growing by the day, added to electromagnetic pollution, the organisms tend to be weaker and weaker with time, and when certain weaknesses are present, the effect of Chlorine and DPB / THM tend to become more and more present.

That means that older studies are maybe not that accurate anymore and new studies with more varied way of investigation shows a different story than first thought. Also come into play habits: Scientists have habits for thinking and don't change it fast, especially if it breaks the economic paradigm which would force everything to change: like in agriculture, medicine, water.

Anyway instead of being stuck into logic alone which makes you running in loop, it's better to let your instinct and your intuition guide you: Chlorine is a killer of bacteria, you're made of bacteria, why taking a chance putting both in presence? Don't you feel Chlorine is harmful?
