The U.S. Army Survival Manual Fm 21-76 contains some important facts about maintaining hydration while being outdoors:
- Eating increases dehydration because your body uses water to carry off wastes from food and, thus, you can maximize your body’s water supply by eating less.
- Thirst is not an indication of how much water your body needs and, thus, drink regularly to prevent hydration but do not base your drinking regiment on your thirst.
- At 68 degrees Fahrenheit, an average adult loses/requires two to three liters of water daily. What’s more, in situations with high altitude, heat, and/or cold, your body requires more water.
- You should urinate approximately one pint a day.
Hikers and mountain bikers can stay hydrated and maintain performance by using hydration backpacks, eating energy gels, and carrying BPA-free water bottles. What’s more, hikers can bring collapsible travel pet bowls for their dogs.
