Dehydration risk in cold

• A. More thirst and increased intake
• B. No fluid loss
• C. Less thirst but high fluid loss
• D. Fluid loss only with hot weather

Answer: (C)

In cold environments, dehydration risk often comes from a mismatch between what your body needs and what you actually drink. Your thirst signal tends to be blunted in the cold, so you may not feel thirsty even as you’re losing fluids. At the same time, the air you breathe is dry, so you lose water with each breath, and the body can even increase urine production in the cold (cold diuresis). That combination means you can have relatively low intake but substantial fluid loss, making dehydration a real possibility. The idea that you’d have to have hot weather to lose a lot of fluid isn’t accurate here, and it’s not guaranteed you’ll feel more thirsty or that there’s no fluid loss in cold. So this option best describes the dehydration risk in cold conditions.
