Chlorine in your Shower

When unfiltered water is heated, the chemicals evaporate out of the water and are inhaled. They can also spread through the house and be inhaled by others. House holders can receive 6 to 100 times more of the chemical by breathing the air around showers and baths than they would by drinking water.

  1. In fact, inhalation and skin absorption of chloroform and chlorine by-products is greatest in the shower, where these gases are vaporized. Taking a shower exposes you to the equivalent of consuming an additional two litters of chlorinated water each day. Showers lead to a greater exposure to toxic chemicals contained in water supplies than does drinking water.
  2. The exposure to vaporized chemicals in the water supplies through showering, bathing and inhalation is 100 times greater than through drinking water. During long hot showers, toxic chemicals are inhaled in high concentrations.
  3. Showering is suspected as the primary cause of elevated levels of chloroform in nearly home bacuase of the chlorine in the water.
  4. Also, the total inhalation exposure (summation of the three scenarios; shower pre-post cooking acitivities and cooking) was found to be comparable with that for firect ingestion, indicating that inhalation is an important pathway for the THM exposure from drinking water (SCI TOTAL ENVIRON, 2000).

Effects Of Chlorine on Colored Hair

Chlorine salt crystallization process may also affect the hair cuticle. The cuticle is an outer layer of very hard, dead cells over the  hair surface. If the chlorine gets between the scales it could push up the scales; therefore, making it rough and prone to damage of breakage. These flaked cuticles reflect light poorly and so the hair fibre looks dull, dry and may fell rough when touched.

As a bleach, chlorine strips color from your hair. Blond hair may acquire a greenish tinge. Darker shades of hair may become dull, dry out and lose the gleam and highlights that the color treatment added. 

Chlorine has a damaging effect on color-treated hair. As a bleaching agent, chlorine doesn’t just change hair color, it can damage and dull the hair. 

Chlorine removes natural oils covering hair resulting in loss of hair shine and flexibility, as well as masking them more susceptible to mechanical damage. 

Reaction of chlorine with keratin results in creation of water-soluble chemicals and weakens chemical bonds between fibres forming hair shafts. As the crystallization process develops inside the hair, the chlorine crystals separate the hair fibres disrupting structural integrity of hair shaft. Once bonds are broken, the hair becomes weak and ends of the hairs split. 

Chlorine can change electrical charge of mineral bonded hair and oxidize those minerals. 


How does Chlorine affect my health?

According to the U.S NEWS&WORLD REPORT,1991, drinking chlorinated water may as much as double the risk of Bladder Cancer, which strikes 40,000 people a year. Also, a new statistical analysis indicate that people who drink chlorinated water run a 21% greater risk of bladder cancer and 38% greater risk of rectal cancer than people who drink water with little or no chlorine. Based on this study that there is an association between cancer and chlorinated water  (PREVENTION, Aug 1994). 

The use of chlorine for water treatment to reduce the risk of infectious disease may account for substantial portion of the cancer risk associated with drinking water (ENVIRON HEALTH PERSPECT, Nov 1995).

How does Fluoride affect my health?

Most Australians have been regularly consuming low amounts of fluoride since it was added to drinking water in the 1960s and 1970s to prevent tooth decay. However, several controversial studies ( Fluoridation Water) in recent years have suggested the mineral may be linked to lower intelligence in children and thyroid problems that can cause weight gain, fatigue and depression.

Is there an alrernative to using Chlorine in my pool?

“There is something called UV Filtration, where ultraviolet light kills off existing bacteria in the pool, but it won’t kill the bacteria brought in by people getting into the pool, neither will a similar method called ozone.  Both methods still need a low level of chlorine in the water to meet safety standards. However, Chlorine may work to kill off unwanted germs and bacteria but overdoing this can lead to many irritants and pose serious long-term health problems, if not appropriately calculated”, POOLONOMICS, 2018.
