From Sunday, the temperatures are again high. But before cooling off in a swimming pool, you should be careful about the effects of chlorinated products on the skin. Dr Didier Coustou, dermatologist at Clinique La Croix du Sud, explains how to avoid chlorine-related skin problems this summer.
– Why doctor: On July 16, several people were victims of chlorine poisoning in a swimming pool at the Espiguette campsite in Grau-du-Roi, in the Gard. Some residents who had bathed in the large bath presented a skin reaction. How often can this type of incident occur?
Didier Coustou: Chlorine is a product used by pool owners to disinfect pool water. In most cases, when respecting the standards and the dosage of chlorine, there are no problems for the skin. On the other hand, if the pH (potential Hydrogen) is basic or too acidic, it is possible to suffer from a skin reaction after swimming. This reaction is not necessarily linked to chlorine but to the pool water which is not suitable.
– Can you be allergic to chlorine?
Chlorine allergy does not exist. But we can speak of hypersensitivity to chlorine. Clearly, some have skin that is more sensitive than others to exposure to these disinfectant products. Those at risk are infants and patients with eczema and skin diseases.
– What are the consequences of prolonged skin contact with chlorinated swimming pool products?
In people with sensitive skin, prolonged contact with chlorine can cause irritation, stinging, tightness and red patches. This product can also make hair dry and brittle and irritate the scalp. Exposure to this disinfectant may cause asthma and respiratory tract irritation, i.e. feeling of itchy eyes and nose.
– When should a doctor be consulted?
It is advisable to go to a health professional if an abnormal reaction occurs after prolonged contact with chlorinated products and prevents us from swimming in the pool. Another case: if the red patches are very visible and persist, medical advice should be sought.
– What steps should be taken to prevent the occurrence of chlorine-related skin problems?
To avoid suffering from irritation, it is recommended not to take a dip directly after the chlorine has been poured into the pool. After having bathed, one must always rinse with fresh water and insist on the face, more precisely the contour of the eyes, the mouth and the scalp. Another tip: put on a moisturizer to prevent the skin from drying out.
Patients affected by eczema should apply a barrier cream before going to the swimming pool. This product will help isolate the skin, protect sensitive areas and prevent stinging and irritation. Chlorine-sensitive people can also wear goggles and a swim cap when swimming.
