Altitude Accommodation in Nepal: Tips for Sleeping Well at Height

Why Altitude Affects Sleep

Above 3,000 metres, reduced atmospheric oxygen causes a predictable physiological response. Breathing becomes faster at rest. Waking at night is common as the body adjusts its respiratory rate. Vivid dreams and restless sleep are almost universal in the first one to two nights at any new altitude. These symptoms are normal and usually resolve after two to three nights at the same elevation, provided you are not pushing higher too fast.

The Golden Rule: Climb High, Sleep Low

The cardinal principle of altitude acclimatisation is to spend daytime hours moving to higher elevations but return to sleep at a lower one. This means accepting that the accommodation where you sleep might be 500 to 700 metres below the highest point you reached that day. Many standard trekking itineraries build in this principle — the Namche to Everest View Hotel acclimatisation day and the Manang rest day on the Annapurna Circuit are designed around it.

Choosing the Right Room at Altitude

At high-altitude teahouses, room selection matters more than at lower elevations. Considerations include:

Heating: Above 4,000 metres, rooms become extremely cold at night. A room adjacent to the dining room (which has a central stove) retains more warmth than a distant room at the end of a corridor. Ask when you arrive which rooms are warmest.

Ventilation: Paradoxically, well-ventilated rooms at altitude support better sleep. Tightly sealed rooms with inadequate ventilation accumulate CO2, which worsens altitude symptoms. A slight crack in the window is beneficial.

Noise: Teahouses are communal. Dining room conversations, generator noise, and neighbouring trekkers' coughs all penetrate thin walls. Upper floors are quieter in most properties. A pair of foam earplugs is one of the most valuable packing items for an altitude trek.

Sleeping Equipment

Even at lodges with blankets, a sleeping bag rated to at least -10°C is essential above 4,000 metres. Temperatures inside teahouse rooms regularly approach freezing once the wood stove in the dining room dies down overnight. A sleeping bag liner adds two to four degrees of warmth and improves hygiene between washes.

What Helps Sleep at Altitude

• Arrive at your night's accommodation by mid-afternoon and rest before dinner
• Eat a light evening meal — avoid alcohol and heavy food, both of which impair sleep at altitude
• Drink two to three litres of water during the day
• Avoid sleeping tablets at altitude — they suppress the breathing rate response that protects you from hypoxia
• Diamox (acetazolamide), taken as a prophylactic with medical advice, can significantly improve sleep quality at altitude

When to Descend

Waking in the night with a severe headache that does not respond to ibuprofen, chest tightness, or significant coordination problems are signs of altitude sickness that require immediate descent, regardless of what time it is. No accommodation choice or medication substitutes for descending when serious symptoms appear.

FAQ

Is it safe to sleep at Everest Base Camp (5,364 metres)?
Experienced trekkers who have acclimatised properly through a standard itinerary (usually 12 to 14 days from Lukla) sleep one night at Base Camp. It is not a dangerous altitude for fit, well-acclimatised individuals, but sleep quality there is generally poor even for experienced trekkers.

Do teahouses above 4,000 metres have heating in rooms?
Rarely. Most teahouses provide heating only in the communal dining room. Going to bed in your full base layer, with a proper sleeping bag, is the standard practice.
