According to studies, swimmers experience higher rates of illness due to which of the following?

The higher rates of illness experienced by swimmers are primarily associated with swimming in contaminated water. Various studies indicate that pools, lakes, and other bodies of water can harbor pathogens due to improper sanitation or environmental pollution. Contaminated water sources can lead to gastrointestinal illnesses, respiratory infections, and other health issues for individuals who are exposed while swimming.

Swimming in contaminated water often involves the presence of harmful bacteria, viruses, and parasites, which can be introduced through fecal matter, urine, or runoff from nearby land. Swimmers, particularly those who ingest water, are at greater risk of contracting illnesses caused by these pathogens.

While factors such as age, regulatory practices, and swimmer density may play roles in overall health and safety, the direct link between illness and contaminated water is well-established in research. Hence, the focus on the quality of the water itself is crucial in understanding the health risks associated with swimming activities.
