Chlorine is the number one contaminate in our drinking water! This chemical is added to our water supply as a way to purify water and kill off microorganisms and other waterborne pathogens. Chlorine has several side effects as well. The municipality does not simply use chlorine because it is the safest and most effective means of disinfection, rather because it is the cheapest method. Discover the Health Risks Of Chlorine below:

1. Risk of Cancer

Researchers have found that people who drink and bathe in chlorinated water over a long period of time have a greater risk of getting bladder, rectal and breast cancers. Studies have shown that by-products created in the chlorine disinfection process create trihalomethanes (THMs). When THMs are ingested they encourage the growth of free radicals that can destroy or damage vital cells in the body. This can cause cancer. Below is a list of by-products that caused cancer in lab animals.

  • Haloacetic acids (HAAs)
  • Trihalomethane (THMs)

2. Hazardous To Your Child’s Health

Some studies have shown that drinking and bathing in chlorinated water can potentially increase the risk of asthmatic attacks in children. In other studies, mice that were exposed to chloramines and chlorine grew tumors in their intestines and kidneys. If the skin is exposed to chlorinated water, irritation and burning may occur.

3. Cell Damage

It’s no secret that chlorine kills living organisms. Drinking and bathing in water that has chlorine will destroy cells and tissue in our human bodies. We are just complex organisms. This could explain the carcinogenic behavior of chlorine.

4. Asthma Risk

Drinking, bathing and swimming in chlorine contaminated water will increase your chance of developing respiratory problems. In some Florida cities, the concentration of chlorine in tap water is just as high as in swimming pools. This can cause irritation of the airways. Chlorine contaminated water causes the following symptoms:

  • Sneezing
  • Tightness in your chest
  • Weak cough
  • Mild sore throat
  • Increased dryness in your throat
  • Irritation in your nasal passages

5. Heart Problems

Studies have shown that exposure to chlorine can cause some serious threats to your cardiovascular system. Scientists conducted a test where they used two groups of animals to test on to find out the basic cause of atherosclerosis that eventually leads to strokes and heart attacks. One group of animals was giving chlorine contaminated water while the other got filtered water. The results of this experiment confirmed that the animals who drank the chlorine contaminated water showed some levels of heart and circulatory diseases.
