Severe Symptoms — HACE / HAPE
Above 3,000m: gain no more than 300–500m altitude per day. "Climb high, sleep low." In Iceland this applies above 1,500m.
Drink 3–4 litres of water per day at altitude. Dehydration worsens AMS symptoms dramatically.
Alcohol suppresses breathing during sleep and dramatically worsens acclimatisation. Avoid the night before and during ascent.
Sleep at a lower altitude than your highest point of the day. Your body acclimatises during sleep.
For peaks above 2,000m, ask your doctor about acetazolamide (Diamox). It speeds acclimatisation but has side effects.
For Hvannadalshnjúkur and other glacier peaks, a certified IFMGA mountain guide is essential for safety.
