Final answer:
It is true that performing treading water correctly enables a person to keep their head above water for breathing. Recognizing real drowning signs and delivering timely rescue and CPR are critical for water safety.
Step-by-step explanation:
It is true that when treading water is performed correctly, a student will be able to keep their head above water and breathe for minutes at a time. Treading water is a fundamental skill for staying afloat and being able to breathe while in the water, which is essential for safe swimming practices. It requires the swimmer to use their limbs in coordinated movements to create enough lift in the water to keep their body afloat and their head above the surface, thus allowing for breathing.
However, if someone is drowning, it's important to understand that shouting or calling for help might not be possible due to a muscular spasm that seals the airway, preventing both air and water passage. Instinctive drowning responses may not be visually dramatic as often depicted. Therefore, recognizing the real signs of drowning and understanding the importance of prompt rescue and administering CPR, only after the individual is removed from water, is crucial for saving lives.
