Chlorine Side Effects In Drinking Water | How Much Is Too Much?

Too much of a good thing can have some nasty side effects. And that includes chlorine in your drinking water.

Since we get a lot of our drinking water from open sources like lakes and reservoirs, it is necessary to kill all the pathogens.

Nobody is suggesting that killing the bacteria and pathogens in the public drinking supply is a bad thing. But, is too much chlorine actually bad for you? And how much is too much? Knowing the side effects of chlorine in tap water is the first step towards treatment.

Many people are starting to take a closer look at what is in their water and are beginning to have second thoughts about that chlorine. From the effects on your hair and skin to even more serious problems, it seems like chlorine is a double edged sword.

Once you understand the chlorine side effects in your tap water then read on to find out how to remove it from your drinking water and shower.

Is Chlorine in Tap Water Safe?

The short answer is, yes, it is safe to have chlorine in your drinking water. The safe level of chlorine in drinking water is up to 4 parts per million according to the EPA. (Source)

The EPA, though also reports that there are side effects even at lower levels. So even though it is technically safe to drink water with that maximum limit, many people will react differently.

Here are some side effects reported by the EPA:

  • Potential irritant to the lungs, upper respiratory tract and the eyes.
  • Under 0.054 parts per million (ppm) can exhibit tickling of the nose and throat.
  • 0.06 to 0.3 ppm shows stinging and dryness of the nose and throat.
  • 1 ppm and over can lead to coughing, shortness of breath and headaches.
  • Over 30 ppm can result in burns to the skin, vomiting and diarrhea.

Some have claimed that high doses of chlorine can lead to cancer, but it is unclear if there is a link. The EPA does acknowledge, however, that studies show an association between bladder and rectal cancer linked to the organic compounds found in chlorinated water.

When chlorine reacts with the presence of organic matter in the water it produces Trihalomethanes which are possible carcinogens.

Chlorine and your Gut Health

People are trying to get more and more probiotics in their diet lately, but the problem is that too much chlorine actually kills a lot of the beneficial bacteria in your system. 

That’s how effective chlorine is at killing bacteria that it even takes away those that we need.

Because of this our immune system gets weakened and causes us to get sick more often. If you are getting more and more susceptible to colds, stomach bugs and other common ailments, it may mean that your immune system is weak and chlorine might be the reason why.

Chlorine Effects on the Skin and Hair

One of the many effects of chlorine on your skin and hair is that it strips them of your natural oil. This leads to dry, flaky and often irritated skin and scalp. And as for your hair, it can end up brittle and hard to manage.

If you have acne you may see it begin to go away if you’ve only just started showering in a new place that has highly chlorinated water. But, over time your acne will actually get aggravated and end up causing more painful acne than before.

Read this article to learn all about if it’s safe to drink shower water.

If you have dyed or treated hair, you may really end up worse for wear if you shower with a lot of chlorine in the water supply. In fact, you may see your hair turn different shades of green in some extreme cases.

You can just deal with the excess chlorine and its side effects on your hair and skin by using moisturizers and other skin care products. Or, you can solve the problem at its source and go for shower heads that remove chlorine from your water as it passes through the head. 

More on that later in the article. If you want an in-depth article about the best shower head filters then click that link to read all about them.

Chlorine and Eczema

There are different types of eczema and the chlorine in your water will have different effects depending on the reason why you have it.

What I mean by that is if you get eczema or dermatitis as a rash from contact like from a plant, then the chlorine may actually help your eczema. It dries out your skin and washes away the cause of the irritation so it could actually calm the dermatitis in this case.

If you have an autoimmune eczema then you’re likely to see your itchy spots become even worse. This is why people with chronic eczema are wary about swimming in pools. 

It is hard to avoid showering or bathing in the water in your home, however.

How to Remove Chlorine from Tap Water

Removing chlorine from your drinking water and shower is easy, cheap and fast. You don’t need a plumber or any special knowledge. All you need is a filter. Which kind depends on your needs.
