Avoiding the Khumbu Cough on Your Everest Trek

Health Tips for the Cold, Arid Mount Everest Expedition Trail

The Hacking Hazard

The 'Khumbu Cough' is a dry, persistent cough that affects almost everyone who goes Everest trekking. It is caused by breathing the sub-zero, bone-dry air found near the Mount Everest summit region.

The Power of the Buff

The best prevention is to wear a buff or mask over your mouth and nose 24/7. This traps the moisture from your breath, creating a humid climate for your lungs as you approach Everest Base Camp.

Warm Drinks and Hydration

Drinking cold water irritates the throat. Successful Mount Everest expedition members stick to warm tea and soup. Keeping the membranes moist is the key to preventing the cough from starting.

Sucking on Lozenges

Hard candy or throat lozenges stimulate saliva and provide a coating for the throat. It is a simple but effective tool to keep your lungs healthy for the final push toward the Mount Everest summit view points.

Protect Your Lungs

A severe cough can break ribs or prevent you from sleeping. Be disciplined about covering your face during your Everest trekking adventure.
