Altitude Sickness: What You Need to Know Before Trekking to High Altitudes

🧠 What is Altitude Sickness?

Altitude sickness (Acute Mountain Sickness or AMS) can affect anyone ascending to higher elevations too quickly, regardless of fitness or trekking experience.

Symptoms can begin as low as 2,400 meters (8,000 ft) and become more severe above 3,000 meters (10,000 ft).

💡 Did You Know?
At 5,500 meters (18,000 ft), oxygen levels drop to 50% of what’s available at sea level.
