What factors contribute to the risk of drowning?

The factors that contribute to the risk of drowning include strong currents, lack of supervision, and fatigue. Strong currents can overpower even skilled swimmers, making it difficult to stay afloat or swim back to safety. Lack of supervision is critical, as designated lifeguards and attentive adults can help prevent accidents and quickly respond in emergencies. Fatigue can affect a swimmer's ability to maintain performance in the water, leading to decreased strength and coordination, which increases the risk of drowning.

The other options present elements that could either mitigate risk or are not associated with increased risk. Swimming in shallow water does not inherently increase drowning risk compared to deep water, and wearing life jackets is a safety measure that helps prevent drowning. Staying within designated swimming areas is a practice that enhances safety by ensuring that swimmers are in environments where lifeguards can monitor their activities. Regular swimming practice and training improve swimming skills, which reduces the risk of drowning.
