What are the potential effects of extremely high chlorine levels in pool water?

Extremely high chlorine levels in pool water can lead to skin irritation and respiratory issues for swimmers. When chlorine concentrations rise significantly, it can irritate the skin, causing rashes and discomfort, especially for individuals with sensitivities. Additionally, inhaling high levels of chlorine vapors can result in respiratory problems, including coughing, throat irritation, and exacerbation of asthma symptoms. This underscores the importance of maintaining appropriate chlorine levels to ensure swimmer safety and comfort.

In contrast, while cloudy water and algae growth are common concerns in pools, they are typically associated with insufficient chlorine levels rather than excess. The statement about more frequent chemical treatments being needed may be misleading as high chlorine levels could actually reduce the need for additional chemicals for a brief period. As for increased water temperature, chlorine levels do not directly affect the temperature of the water.
