What often occurs when a drowning person attempts to breathe?

When a drowning person attempts to breathe while underwater, they often instinctively inhale, which leads to swallowing large amounts of water instead of air. This inhalation reflex occurs because the body's natural response to the lack of oxygen and the urge to breathe can overpower the instinct to hold one's breath. In attempting to breathe, the person inadvertently takes in water into the lungs, which can contribute to the drowning process. This situation is critical because the presence of water in the lungs can lead to asphyxiation and decrease the chances of survival. Understanding this physiological response is essential for lifeguards and rescuers, as it highlights the urgency of performing rescue techniques or providing assistance to prevent water ingestion during a drowning incident.
