While swimming is one of the best activities to beat the summer heat. For some, swimming can sometimes cause issues for people who deal with allergies. Besides normal allergies, such as mold, dust, and pollen, it might seem like you’re allergic to swimming pools. In fact, many people are adversely affected by chlorine and other chemicals that are present in pool water.
Allergic to Swimming Pools: Is My Swimming Pool Affecting My Allergies?
But, just because you’re being affected doesn’t mean you are allergic. In fact, no one can be allergic to chemicals like chlorine. That being said, you can be more sensitive to these kinds of chemicals than most. The most common complaints include itchy eyes and skin, fatigue, and feeling miserable. The good news is that even though it’s not technically an allergy, an allergist can still help alleviate symptoms and help you get back in the water.
Chlorine Sensitivity and Chemical Congestion
Chlorine itself is a toxic chemical that can cause fatal exposure in certain forms. It’s only used to control bacteria and micro-organisms in minimal amounts that generally won’t affect larger animals. Without chemicals like chlorine, pools, fountains, and aquariums would become hot spots for water-borne diseases such as cryptosporidium and E. coli. The amount of chemicals needed is calculated by how dirty the water is; one widespread method to clean pools is to “shock” the water with too much chlorine to eradicate any organic buildup.
Common symptoms of chemical congestion include:
• Itchy and watery eyes
• Hives or rash on the skin
• Asthmatic reaction
• Runny nose and congestion
Even when chlorine isn’t present, alternative pool chemicals that are used to adjust the water’s pH balance can cause similar effects. As well as the pH balance, anything above or below the safe area between 7.2 and 7.8 can also cause adverse reactions.
You Can Do a Few Things to Help Lessen These Events:
- Limit exposure
Limiting your time in the water can help reduce the severity of reactions.
- Shower afterward
It’s important to shower immediately after swimming to remove any chemicals.
- Stay outdoors
Chlorine vapor can build up around indoor pools, increasing the severity of any reactions.
- Try saltwater
Saltwater pools don’t require as much chlorine or chemical intervention to stay clean.
- See an allergist
Only a doctor can pinpoint any specific sensitivity or reaction. Treatment options vary depending on the frequency and severity of reactions.
People with severe reactions and events should be taken to an urgent care clinic to help bring the symptoms under control. Exposure to chlorine or chemicals can contribute to adverse allergy events by irritating the sinuses, respiratory tract, and lungs.
Frequently Asked Questions
Technically, people cannot be allergic to swimming pools themselves or to chemicals like chlorine. However, some individuals are more sensitive to these chemicals, which can cause symptoms such as itchy eyes, skin irritation, fatigue, and general discomfort.
Common symptoms of sensitivity to pool chemicals include itchy and watery eyes, skin rashes or hives, asthmatic reactions, runny nose, and congestion. These reactions occur due to chemical irritation rather than a true allergic response.
Chlorine is used in pools to kill harmful bacteria and pathogens but can irritate the eyes, skin, and respiratory system in sensitive individuals. Irritation from chlorine or other pool chemicals may worsen allergy-like symptoms or asthma.
Swimmers can limit their time in the water, shower immediately after swimming to remove chemicals, choose outdoor pools to avoid chlorine vapors, and consider saltwater pools which use fewer chemicals. Consulting an allergist can also help manage symptoms effectively.
Chlorine and other chemicals are essential to maintain pool hygiene by killing bacteria and pathogens that cause waterborne illnesses like cryptosporidium and E. coli. Without these chemicals, pools would become unsafe and breeding grounds for diseases.
Yes, alternative chemicals used to balance pool water's pH can also cause irritation and sensitivity reactions. Maintaining a proper pH range between 7.2 and 7.8 is important to minimize adverse effects on swimmers.
If you experience severe reactions such as difficulty breathing, intense skin rashes, or prolonged congestion after swimming, you should seek urgent medical care. An allergist can assist with diagnosis and treatment for ongoing sensitivity to pool chemicals.
