I’m pretty sure drowning while on land after leaving the water is a thing

Edit - Yup, “Secondary drownings can develop hours after a swim, bath or anything that occurs with water. Secondary drowning is without water remaining in the airways. It is a secondary injury which is often classed as a drowning incident.

It’s is a very mild form of drowning, You take a bit of water and sputter and cough, but seem OK shortly thereafter. Over time, a reaction develops in the lungs. The water itself is gone, but the lungs become inflamed. There is a change in blood flow that impacts the lung sacs.”
