**Struggling with pounding headaches, nausea, or dizziness on the second day of a trek?** You’re in the right place. Below is a step‑by‑step, day‑by‑day schedule that lets your body adapt to thin air, keeps you hydrated, and eliminates those dreaded mountain‑illness symptoms—so you can enjoy the summit without the pain.

## Why Headaches Happen at High Altitude

Moving up too quickly is the main trigger. When you ascend from base camp to a much higher camp in a single day, your body can’t produce enough red blood cells to carry the reduced oxygen. Add **inadequate hydration** and **skipping rest days**, and the symptoms snowball into a throbbing headache and nausea.

## 3‑Day High‑Altitude Acclimatization Schedule

| Day | Elevation Gain | Activities | Hydration & Nutrition |
|-----|----------------|------------|------------------------|
| **Day 1** | 0 → Low camp (≤ 2,500 ft) | Light hike to trailhead, set up camp, **rest** | Drink **≥ 3 L** water, add a pinch of salt to meals |
| **Day 2** | +1,000 ft | Moderate hike to mid‑camp, stay overnight | Continue **≥ 3 L** water, electrolytes, monitor for any headache |
| **Day 3** | +1,000 ft (or stay) | Slow ascent to high camp, **pause** if symptoms appear | Same hydration routine, rest fully before any further climb |

**How it works:** Each night you give your body a full 24 hours at a new altitude, allowing it to increase red‑blood‑cell production and adapt to lower oxygen levels. The built‑in rest days also give you a chance to **re‑hydrate** and **replace lost electrolytes**, which are crucial for preventing altitude headaches.

### Quick Checklist for Each Day
- **Hydrate:** Aim for **3 L of water** plus electrolytes.
- **Salt:** Sprinkle a pinch of sea salt on meals to retain fluids.
- **Pace:** Treat the ascent like a **leisurely walk**, not a race.
- **Monitor:** If you feel any headache or nausea, **stop, rest, and hydrate** before continuing.

## Key Tips for Successful Acclimatization

- **Never skip a rest day.** Even if you feel fine, the body still needs time to adjust.
- **Listen to your body.** Early dizziness is a warning sign—ignore it at your own risk.
- **Carry a hydration pack.** Easy access to water makes reaching the 3‑liter goal effortless.
- **Use salty snacks.** Pretzels, nuts with added salt, or electrolyte tablets keep sodium levels stable.

By following this **simple three‑day schedule**, most trekkers see a dramatic drop in altitude‑related headaches and can keep climbing with confidence.
