In polar environments or high mountains, the need for water remains as vital as in warm climates. However, the cold deceives the sensation of thirst, and access to water becomes a real challenge.
In this article, discover 4 simple and effective techniques to hydrate safely in cold weather.
1. Melt snow carefully
Clean snow can be melted to obtain water, but never consumed directly: it drastically lowers body temperature.
Melt it gently over a flame or in a water bottle under your clothing. Do not fill your container completely with snow: it must first be packed down.
2. Use ice instead of snow
Compact ice contains more water than snow. It melts more slowly but more efficiently.
Prefer clear blocks or surface frozen water from lakes or rivers. Filter it afterwards if you suspect contamination.
3. Protect your reserves from freezing
Once you have stored water, keep it close to your body in a water bottle or an insulated pocket.
Never leave a bottle exposed to the open air, even in a bag: water freezes quickly there. Wrap it in a warm cloth or place it under your clothing.
4. Drink regularly, even without thirst
The cold suppresses the sensation of thirst, but dehydration remains a real danger.
Force yourself to drink small sips every 30 to 60 minutes. Avoid icy drinks, and prefer lukewarm or body temperature water.
Conclusion
Water remains the key to survival, even in freezing weather. By anticipating melting, insulating your reserves, and drinking regularly, you ensure your hydration and physical efficiency, regardless of the conditions.
