Why Does Cold Water Increase Survival Rates in Drowning Incidents?

[K.E]

People who have been submerged in very cold water, and presumed drowned, have sometimes been revived. By contrast, people who have been submerged for a similar period of time in warmer water have not survived. Suggest reasons for this difference.

I know this has to do with the fact that higher temperatures increase the rates of reaction because more particles collide with enough energy to react. But I am not sure of how to relate that to this question.

Thanks!

Think how fast oxygen is used by the tissues.

Is it because oxygen dissolves more easily in cold water than in warm water? Also because when the water is warmer, its molecules move and vibrate faster, making it easier for oxygen molecules to escape from solutions?

No, it is not about amount of oxygen dissolved in water. It is about oxygen in the body.
