Quick Answer
Carrying extra food in whiteout conditions is crucial for survival, as it increases the chances of staying warm and alive in case of prolonged navigation delays or getting lost.
Preparing for Whiteout Navigation
When venturing into whiteout conditions, it’s essential to pack extra food, specifically high-calorie, high-energy snacks like dried fruits, nuts, and energy bars. Aim for at least 1-2 pounds (0.45-0.9 kg) of extra food per person per day, considering the physical demands of navigating in harsh weather. This amount can help sustain energy levels for 24-48 hours.
Caloric Intake in Whiteout Conditions
In extreme cold, the body’s metabolic rate increases to maintain warmth, requiring additional calories to function. A 2,000-calorie diet is common for most adults, but in whiteout conditions, the recommended caloric intake can increase by 50-100% to account for the added energy demands. Packing extra food with high caloric density, such as 2,500-3,000 calories per pound, will ensure adequate nutrition during extended navigation.
Food Storage and Accessibility
When selecting food for whiteout conditions, choose items that are easy to consume while wearing gloves and goggles, such as energy bars, jerky, or canned goods. Store the extra food in a waterproof, easily accessible container, like a backpack or a small dry bag, to prevent damage and ensure quick retrieval in case of an emergency.
