True or False: Swimming in cold water will warm you up and increase your chances for survival.

• A. True
• B. False
• C. It depends on duration
• D. Not enough information

Answer: (B)

In cold water, heat is lost from your body very quickly because water conducts heat away about much faster than air. Moving and swimming might generate some warmth from muscle activity, but that warmth is temporary and the surrounding cold water continually pulls heat away, so your core temperature can drop faster than you can compensate. Fatigue from swimming in frigid water further reduces your ability to stay afloat and increases the risk of drowning, which hurts survival chances more than it helps. The safer approach to survive is to conserve energy and heat—stay with a flotation device or get out of the water if possible, minimize movement to reduce heat loss, and hope for rescue. So, the statement is false.
