Hydration Hacks for Trekkers: The Science Behind Water and Salts
“Dehydration doesn’t knock. It creeps up on you — one step, one breath at a time.”
Imagine yourself Trekking in The High Himalayas. The sun is gentle, the breeze is cool, and you’re not sweating at all — so you skip a few sips of water. By the time you actually feel thirsty, you have waited too long. Your body is running out of hydration, and the mountain runs on its own schedule.
Hydration isn’t just drinking water. It’s a science: a fine balance of fluids and electrolytes that keeps your engine running. This blog is an overview of the science and some hydration options for trekkers and trek leaders.
Why Hydration is More Important While in the Mountains
Trekking — especially at high altitudes — exposes your body to unique stressors.
- You breathe faster, and you lose water in the air you exhale.
- Humidity is lower, so even if you aren’t visibly sweaty, you’re losing moisture.
- You will urinate more frequently while trekking at elevation; urinating frequently is a natural reaction to altitude.
- You are more susceptible to Trekking in The High Himalayas.
Feeling fatigued, dizzy, or cramping can start with as little as a 1 – 2% change in hydration, and it can become incapacitating in certain terrains.
The Science of Hydration: H20 Doesn’t Always Equal Hydration
Water is simply not enough. In addition to water, we also lose electrolytes when we sweat or urinate. Electrolytes are basically minerals, some of the more common ones are:
- Sodium: Maintains fluid and balances electrolytes in the body and helps nerve function
- Potassium: Regulates muscles contraction and heart rhythm
- Magnesium: Homoeopathy – The primary function of magnesium is to prevent cramps.
- Chloride & Calcium: they aid hydration in addition to electrolytes in the body cells.
Without these, drinking plain water can actually dilute your electrolyte levels, making things worse — a condition called hyponatremia.
Hydration Hacks That Actually Work
1. Start Hydrated — Don’t Chase It Later
Begin your trek fully hydrated. Drink water regularly the day before and on the morning of your trek. A dehydrated start leads to a fatigued finish.
2. Follow the “Sip Don’t Gulp” Rule
Avoid large intakes at once. Sip 150–200 ml every 20–30 minutes. Your body absorbs fluids better in small, consistent quantities.
3. Use Oral Rehydration Salts (ORS) or Electrolyte Tablets
Carry packs of ORS, Electral, Enerzal, or Nuun tablets. Add them to your water once or twice a day to replenish lost salts.
4. Eat Hydrating Foods
Cucumbers, oranges, bananas, soaked raisins, and even simple dal-rice offer both fluid and electrolyte support.
5. Carry a Hydration Bladder
Unlike bottles, hydration packs (like CamelBak) allow hands-free sipping and encourage more consistent hydration.
6. Know the Signs of Dehydration
- Dry lips and mouth
- Headache or dizziness
- Dark yellow urine or reduced urination
- Loss of appetite or cramps
If you spot these, pause, hydrate, and rest.
7. Hydrate Before Bed
Night-time dehydration is common at altitude. A warm glass of ORS water before bed can help prevent early morning fatigue or AMS.
Hydration at High Altitude: Special Tips
- Drink more than you feel you need. Thirst is not always a reliable signal at altitude.
- Avoid diuretics like caffeine or alcohol during treks — they increase fluid loss.
- Trekking in The High Himalayas that mimic dehydration (headache, nausea, low appetite).
Trek Leader’s Tip: Monitor Your Team
If you’re leading a group:
- Check that everyone is drinking — especially first-time trekkers.
- Ask about urine color (it’s a great hydration indicator — pale is good, dark is bad).
- Always carry extra ORS for emergencies.
Bonus: Himalayan Herbal Hydration
Local herbs like rhodiola, tulsi, and seabuckthorn (used in Ladakh) are often added to teas or soups for hydration and altitude adaptation. These traditional remedies can be a great natural addition to your hydration kit.
Final Thoughts: Hydrate Like Your Life Depends On It — Because It Does
In the world of trekking, your bottle is as important as your boots. Every drop you sip fuels your steps, sharpens your mind, and shields you from the harsh elements.
So next time you hit the trail, don’t just pack water — pack knowledge. Understand what your body needs, and give it the right mix of hydration and salts.
