“Over the River and Through the Woods… Eating to ENERGIZE” Kelly Streit, MS, RD Instructor, Food and Nutrition OSU Extension Service Clackamas County
The Great Pacific Northwest Hard physical activity done in a cold/dry/damp environment can result in DEHYDRATION & HYPOTHERMIA
Dehydration = excessive loss of body fluid Symptoms: Fatigue, headache, low/no urine production, elevated HR, lightheadedness, dry mouth, and muscle cramps Contributing Factors: Diuresis, overdressing, fluid deprivation/restriction
In a cold/dry/damp environment, sweat can evaporate so quickly that one does not have a good sense of fluid loss from the body
Fluid losses can exceed 1 quart/day through the respiratory passages
Q: Why do you feel the need to “pee” in the middle of a snowstorm? Blame it on “cold-induced” diuresis
Over dressing Excess body heat production Overdressing excess body heat production profuse sweating Profuse sweating
Fluids are often not readily available during cold weather activity; lack of thirst, fluids may freeze, or intake may be restricted
A cold/dry/damp environment, diuresis, overdressing, and lack of fluids DEHYDRATION
Hypothermia = excessive loss of body heat; decrease in body core temperature <97 degrees F Symptoms: Shivering, euphoria, and confusion lethargy, weakness, slurred speech, disorientation, combative behavior shivering ceases, delirium, coma Contributing Factors: Prolonged exposure to the cold/damp, inactivity, improper dress, low glycogen stores
Hypothermia can develop in relatively mild temperatures (50-65 degrees F)
Begin the day well fueled and hydrated. Rise & Shine & Dine! • Drink 1-2 glasses of water upon arising • Eat a high-carbohydrate, low-fat, and moderate-protein meal to “break the fast” before heading out
Feed your PACE • Balance calorie intake with physical activity • Consider the terrain, clothing, equipment being carried, and changes in temperature
Be Your Own “Pack Mule” • Plan 3-5 meal/snack breaks throughout the day • Include a variety of carbohydrates at each meal/snack • Keep a water bottle with you at all times • Drink BEFORE you are thirsty • Avoid caffeine, alcohol, and other diuretic substances • Drink until you pee clear
Rest, Refuel, & RENEW • Consume a high carbohydrate meal at the end of the day • Rehydrate • Rest
