Staying hydrated is crucial during outdoor activities, whether hiking, biking, skiing, climbing, or running.
How to Carry Water: will depend on the activity. Hydration packs with reservoirs (i.e., a Camelbak) are excellent for hiking, backpacking, and mountain biking. If you prefer bottles, keep them accessible in a mesh pocket on your backpack. Consider handheld bottles, hydration waist packs or belts, or hydration vests for trail running.
Hydration Tips
Take small sips frequently rather than chugging large amounts infrequently.
Snack Regularly: for activities longer than an hour, eat snacks with sodium, potassium, calcium, and magnesium, or add electrolyte replacement to your water.
Higher elevations can lead to dehydration, so drink water more frequently.
Staying hydrated in cold weather is just as important, so consider packing a hot drink.
Pre-hydrate: for high-exertion activities, drink before starting.
Rehydrate Post-Exercise: drink 16-24 ounces of water for every pound lost during exercise.
Plan routes that pass by water sources to avoid carrying excessive weight. In remote areas, carry enough water or bring a water treatment option for refilling from natural sources.
Sunburn can accelerate dehydration, so use sunscreen or sun-protective clothing.
If you forget to drink, set a timer to remind you every 20 minutes.
Preventing Dehydration
Dehydration happens when fluid loss exceeds intake. Early signs include a dry mouth and decreased energy. More serious symptoms are cramps, headaches, nausea, stumbling and dark urine. To prevent dehydration, drink water as soon as you feel thirsty, taking frequent sips.
Preventing Over-hydration
It’s rare but serious. Sodium levels in the blood are depleted, impairing cell function. Symptoms resemble dehydration: fatigue, headache, and nausea. To avoid overhydration, avoid drinking more than you sweat. Eat snacks with sodium or drink sports drinks containing sodium.
Follow these guidelines to stay properly hydrated and maintain peak performance on the trail.
