Year-Round Pool Swimming-Is Chlorine Harmful?

Swimming pools are cherished retreats, offering relaxation and recreation to individuals of all ages. Essential to maintaining these aquatic environments is effective disinfection, and chlorine tablets have long been a popular choice for pool sanitation. However, while chlorine tablets offer advantages in disinfection, they also present limitations and potential hazards. This article delves into the intricacies of chlorine tablets in swimming pool disinfection, exploring their advantages, limitations, hazards, and impact on the human body.

Disinfection Advantages of Pool Chlorine Tablets

Chlorine tablets are renowned for their potent bactericidal properties, providing continuous antibacterial capabilities and effectively eliminating algae, odors, and impurities. With mature technology and 100% effective chlorine content, these tablets are cost-effective for sewage disinfection in swimming pools, ensuring a safe and hygienic aquatic environment.

Limitations of Pool Chlorine Tablets

Despite their efficacy against bacteria, chlorine tablets may fall short in combating viruses and pathogens. They also lack the ability to oxidize complex compounds like general pesticides, and their effectiveness is influenced by pH levels. Additionally, liquid chlorine, an alternative disinfectant, poses health and environmental risks, requiring special safety measures during storage and transportation. Its acidic nature in swimming pools necessitates significant alkali adjustments to balance pH levels, adding complexity to pool maintenance.

Hazards of Pool Chlorine Tablets

Chlorine chemicals, while effective in disinfection, pose risks to human health and the environment. Prolonged exposure can lead to irritation of the eyes and skin, resulting in redness, rashes, and hair discoloration. Chlorine preparations react with organic matter in water, producing carcinogenic compounds, highlighting the importance of minimizing exposure, particularly for children in developmental stages. Moreover, chlorine’s corrosive nature necessitates stringent operational management to prevent damage to pool structures, equipment, and pipes.

Impact of Pool Chlorine on the Human Body

Chlorine’s drying effect on the skin can cause itchiness and discomfort during swimming, leading to dry, chapped skin and the formation of papules. As a hair-drying chemical, chlorine strips the hair of sebum and natural oils, resulting in dry, brittle hair prone to breakage and split ends. Furthermore, chlorine damages hair protein, diminishing its luster and potentially causing discoloration. Highly irritating to mucous membranes, chlorine in swimming water can cause dry, red, itchy eyes with a burning sensation, potentially leading to severe conditions like conjunctivitis (pink eye).


While chlorine tablets offer effective disinfection for swimming pools, it’s crucial to recognize their limitations and potential hazards. Understanding the impact of chlorine on the human body and the environment is essential for maintaining water quality while minimizing health risks, particularly for individuals engaging in year-round swimming activities. Alternative disinfection methods and diligent operational management can mitigate these risks, ensuring a safe and enjoyable swimming experience for all.
