As the altitude rises, the air thins — and your body may not adjust as fast. That’s when Acute Mountain Sickness, or AMS, strikes.
AMS is your body's response to low oxygen levels at elevations above 2,500 m (8,000 ft), common during high-altitude treks, drives, or flights.
It often begins with a persistent headache, followed by nausea, heavy breathing, lead-like legs, and restless sleep—all signs of altitude sickness.
The higher you go, the less oxygen each breath delivers. If you rush your ascent, your body struggles to cope, leading to the symptoms of AMS.
The best way to prevent AMS is to take your time. Climb gradually, especially once you cross the 2,500-meter mark. Your body needs space to adjust.
At high altitudes, your body loses moisture faster. Drinking plenty of water helps blood circulation and reduces the strain on your lungs and heart.
Don’t ignore signs of exhaustion. Rest when needed. Sleep at lower elevations if possible & avoid alcohol or sleeping pills which can worsen symptoms.
For sensitive travelers or tough treks, doctors often recommend medicines like acetazolamide. But always consult a physician before using them.
If symptoms worsen—like confusion, breathlessness at rest, or loss of coordination—descend immediately. Ignoring AMS can be life-threatening.
Climb high, sleep low, and never rush. The views are worth the patience — and your body will thank you for it.
