Hydration Tips for Outdoor Adventures

While outdoor adventures offer extraordinary experiences, they can also challenge your body's hydration levels. Simple tips, like knowing how to recognise dehydration, can make a big difference. It's important to stay hydrated when hiking, camping or simply outdoors, both for your performance and your safety. In this guide, you'll discover hydration tips using expert techniques to help you make the most of your outdoor experiences.

Whether you're camping, hiking or climbing, mastering these hydration strategies will help you stay fresh and alert throughout your journey. Let's get started.

Why is hydration essential for outdoor adventures?

Hydration consists of providing your body with enough water to maintain bodily functions, especially during physical activity. Without proper hydration, your body cannot regulate temperature, transport nutrients or eliminate waste effectively, which is vital during outdoor adventures. When hiking, it's important to consider the amount of water needed for food preparation, such as the amount of water needed to rehydrate freeze-dried foods, as this impacts your daily water requirements and overall hydration during your trip.

It's essential to understand the impact of water and hydration on your backpacking trip, as well as other essential preparation items. For more information, please see our guide on planning a backpacking trip.

Importance of staying hydrated and avoiding dehydration

Dehydration occurs when the body loses more water than it takes in, leading to symptoms such as fatigue, dizziness and confusion. Outdoor adventures often involve physical exertion in hot or dry climates, making dehydration easier. It's important to stay hydrated to avoid these negative effects and ensure your body can meet the demands of the adventure. The following checklist is a good starting point for determining your daily water needs during your trip.

Water and Hydration Preparation Checklist

  • Determine the duration and intensity of your adventure to estimate your water needs.
  • Check the weather forecast to understand your needs based on the climate.
  • Plan water sources along your route, noting where you can replenish.
  • Pack enough water for drinking and meal preparation.
  • Make sure you have purification tools if you plan to use natural water sources.
  • Test your equipment before you leave to ensure it works correctly.

5 tips for staying hydrated on an outdoor adventure

Water is the body's main way to cool down and maintain energy during outdoor activities. It's important to carry enough water, especially when exposed to the elements and engaging in physical activity.

1. How much water to carry based on the duration and intensity of the adventure

Daily water needs depend on activity, environmental conditions and health. For outdoor activities like hiking or cycling, it's advisable to drink 0.25 to 0.5 litres of water per hour. This figure may vary depending on the climate and intensity of the activity. In hot weather or during intense exertion, increase your intake. To avoid dehydration, always carry extra water. To find out how much water to carry, follow this guide to stay hydrated.

Activity Water needed for a day trip (moderate climate)
Hiking 2-3 litres (depending on intensity)
Camping 3-4 litres (including for cooking and other needs)
Cycling 2 to 3 litres (depending on terrain and speed)
Kayaking 2-3 litres (to be adjusted according to duration and conditions)
Skydiving 1 to 2 litres (before and after the activity)

2. Hydration based on weather conditions

Before an outdoor adventure, always check the weather. The climate influences your water needs: in hot and dry weather, drink more to compensate for perspiration. Cool climates slightly reduce these needs, but don't neglect hydration. Adjust your consumption according to the forecast to avoid dehydration and ensure a pleasant experience.

3. Locating safe water resources and water purification methods

In the wilderness, it's important to ensure the safety of the water you drink, as natural sources such as streams, rivers and lakes can be unusual or impure. Avoid drinking stagnant water, as it can harbour dangerous bacteria or parasites. Useful water safety tips include purifying water by methods such as:

  • Boiling,
  • Using purification tablets,
  • Filtering with a portable water filter.

4. Ensuring sufficient water for preparing your meals

When planning meals for outdoor adventures, it's important to consider the amount of water needed to prepare each type of food. Freeze-dried meals are an excellent option for saving water, as they generally only require 1 to 2 cups per meal for rehydration, making them light and efficient. Other foods, such as pasta or rice, often require more water to cook. To manage your daily water needs, carefully plan your meals to stay hydrated, for example by knowing how much water is needed to rehydrate freeze-dried foods.

To help you plan your outdoor adventures effectively, the following table, taken from SLY Foods meal instructions, illustrates the amount of water needed for each meal.

Meal Water needed Equivalent in cups
Creamy Garden Soup 400 ml 2 cups
Chilli Meal 300 ml 1.5 cups
Pad Thai 330 ml 1.5 cups

5. Learn to recognise dehydration and how to treat it

Dehydration can be serious during outdoor adventures. To know how to recognise dehydration, you need to recognise common signs such as dry mouth, dizziness, muscle cramps and dark-coloured urine. Follow hydration tips such as drinking small amounts of water regularly and taking frequent breaks in the shade. If you start to feel dehydrated, finding shade, resting and drinking water immediately can prevent dehydration during your trip.

Hydration equipment for outdoor adventures

The right equipment can make a big difference in how easily you stay hydrated during your adventure. Discover the best options for carrying and filtering water on the go.

Hydration packs or water bottles: Which is the best solution?

Hydration packs are backpacks with an integrated water bladder that allows you to drink hands-free using a tube. They are ideal for hiking or cycling, as they evenly distribute the weight of the water and allow easy access. Water bottles, on the other hand, are simpler and better suited for short trips. The choice between a hydration pack and a water bottle depends on the duration and intensity of your adventure.

Portable water filters

Portable water filters are lightweight devices that can remove harmful bacteria, parasites and sediment from water in the wilderness. These filters are important for long trips where access to drinking water may be limited. Consider a filter that can treat at least 2 to 3 litres of water at a time, so you have enough water for drinking and cooking.

Expert tips to know

It's important for your health and performance to stay properly hydrated during long hikes or strenuous outdoor activities. Here are some practical tips to keep in mind:

  1. Start hydrating early: Start drinking water before your hike to ensure your body is well-hydrated from the outset.
  2. Drink regularly in small sips: Drink small amounts of water frequently instead of waiting until you're thirsty. This helps maintain your water levels throughout your hike.
  3. Carry electrolytes: Add electrolyte tablets to your plan to balance your fluid levels and prevent dehydration. This is especially useful when you're sweating a lot.
  4. Avoid over-hydration: To avoid over-hydration, balance your water intake with electrolytes and listen to your body's thirst signals.

By following these tips, you can ensure your body gets the water and electrolytes it needs to stay energised and safe during outdoor adventures. Avoid dehydration and over-hydration by staying prepared and attentive to your needs.

FAQ

Do you have questions about SLY freeze-dried meals? Below you'll find answers to the most frequently asked questions about the process, preparation, storage, ingredients, and outdoor use.

Freeze-dried food is a cooked dish from which water has been removed under vacuum. The food is first frozen at very low temperatures, allowing the solid water to turn directly into gas through sublimation. It becomes lightweight, stores for a long time, and regains its texture once rehydrated with hot water.

Freeze-drying removes water in the cold, while dehydration uses heat. With freeze-drying, the texture is more pleasant, the flavors are better preserved, and the nutrients are better retained.

Yes. Contrary to popular belief, freeze-dried meals can be very tasty. Freeze-drying preserves the flavors and texture of food. Once rehydrated, the meal regains a texture similar to a home-cooked dish.

At SLY, every recipe is cooked before being freeze-dried, so once rehydrated with hot water, you get a real meal.

Freeze-dried meals are lightweight, quick to prepare and have a long shelf life. They are a simple solution, offering a complete and nourishing meal for outdoor activities or everyday use.

Yes. Freeze-drying preserves vitamins, minerals, and proteins in food—much better than traditional dehydration. At SLY, nutritional quality starts with the ingredients: legumes, grains, vegetables, and plant proteins, for hearty and nourishing meals, whether on a trail or a weeknight.

Yes, but it takes longer (30 to 40 minutes) and the flavor will be less developed. Hot water is recommended for a better result.

Some meals are designed to be rehydrated with lukewarm or cold water. Always refer to the instructions on the packaging.

This can happen if the water is not hot enough, if the rehydration time is too short, or if the meal has not been mixed enough. The water should ideally be boiling (100 °C) for proper rehydration.

Note: altitude reduces the boiling point of water, which can extend the rehydration time required.

They can be stored for up to 5 years at room temperature, in a cool, dry place. For an optimal experience, we recommend consuming them within the first 3 years.

The small sachet in the packaging is an oxygen absorber. It removes residual oxygen from the sachet to preserve food freshness, extend shelf life, and prevent ingredient oxidation.

This sachet is not edible and must be removed before preparing the meal.

Our recipes primarily use legumes (split peas, beans), cereals (rice, wheat, corn), plant-based proteins (soy protein), vegetables, and spices. We also use canola oil, known for its digestibility and richness in unsaturated fatty acids.

Yes. All SLY meals are 100% plant-based. They are suitable for people on a vegan or vegetarian diet.

Some meals may contain common allergens, including wheat, soy, or peanuts. We recommend checking the ingredients list on each product.

All SLY meals are prepared in Quebec, in the Laurentians, specifically in Saint-Agathe-des-Monts. Most ingredients come from Canada or local suppliers. Some recipes use imported ingredients—such as coconut or certain spices—that do not grow here.

Yes. They are lightweight, compact, easy to prepare, and suitable for outdoor activities.

Because water is removed from the food, a freeze-dried meal is much lighter than a conventional meal.

By removing the water, you save approximately 300 to 400 g per meal.

It all depends on the intensity of the activity. An active day may require between 2,000 and 3,000 calories, while an intense expedition can demand up to 6,000 calories per day. Meals rich in protein and calories are recommended to sustain effort over several days.
