What can be a possible consequence of drowning?

A possible consequence of drowning is permanent brain damage due to the lack of oxygen to the brain. When a person is submerged in water and unable to breathe, the brain cells can begin to die within a matter of minutes. This is particularly critical because the brain relies heavily on a continuous supply of oxygen to function properly. If the oxygen deprivation continues for too long, it can result in lasting neurological damage, which may affect cognitive functions, motor skills, and overall quality of life.

The other options do not adequately align with the serious repercussions associated with drowning. Improved swimming skills and enhanced lung capacity are not typical outcomes of drowning; instead, they are associated with effective swimming practices and training. Increased heart rate can occur during stressful situations, such as when someone is struggling in the water, but it is not a direct consequence of drowning itself.
