Getting out of the water as quickly as possible is the best action to take in order to prevent hypothermia after falling into cold water. When a person is submerged in cold water, the body loses heat much faster than it does in air, and prolonged exposure can lead to a dangerous drop in body temperature.

Exiting the water minimizes further heat loss and allows the individual to get to a warmer environment where they can start to rewarm their body. Additionally, once out of the water, putting on dry clothing, wrapping in a blanket, and consuming warm drinks can significantly help in rewarming efforts.

Remaining in the water until help arrives not only prolongs exposure to cold, increasing the risk of hypothermia, but also puts the individual in a more vulnerable position. Swimming vigorously to shore may seem like a proactive measure, but it can actually deplete energy quickly and may lead to exhaustion, further complicating the situation. Waiting for the water temperature to rise is impractical, as water temperatures do not change significantly in a short period and doing so might be life-threatening.
