Plan at a glance
- Keep the first days adjustable rather than fully booked
- Discuss your actual route and overnight altitudes before travel
- Save a clear contact and emergency plan before arrival
Altitude matters even on a city trip
Lhasa altitude sickness is a practical concern because the city is roughly 3,650 metres above sea level. You do not need to be trekking to be affected. Fitness is not protection, and feeling well on a previous trip does not guarantee the same response this time.
Arrange a pre-travel medical discussion if you have an existing condition, a previous altitude problem or a rapid ascent planned. Bring the actual itinerary and overnight elevations. This page provides general travel information, not a diagnosis or an individual decision about whether you should travel.

Build room for adjustment into the itinerary
Gradual ascent is preferable where possible. CDC advises avoiding alcohol and strenuous exercise during the first 48 hours at high altitude. Keep the arrival transfer simple and leave the first sightseeing plans easy to change.
Ask the planner to identify the sleeping altitude of each later stop, not just its distance from Lhasa. A lake excursion or mountain overnight can mean another substantial ascent. Reaching Lhasa comfortably does not establish that you are ready for every higher destination.
Choose flexible bookings for the early days and agree who can change them. Ask about hotel stairs, the distance from the vehicle to the room and the nearest appropriate medical service. These details are useful before arrival, when you can make decisions without pressure from a timetable.

Tell someone if you feel unwell
Headache, nausea, dizziness, unusual tiredness and sleep difficulty can occur after ascent. Tell your guide or companion promptly. Do not continue to a higher altitude while symptoms are present, and seek medical advice rather than assuming every illness is harmless altitude discomfort.
If symptoms worsen at rest or do not improve, obtain medical help and arrange descent as advised. Do not hide symptoms to keep the group on schedule. A paid booking or a desire to see the mountain is not a reason to continue upwards.

Recognise an emergency and get help
Confusion, difficulty walking or coordinating movements, severe drowsiness, or breathlessness while resting require urgent medical attention at altitude. These can indicate serious illness. Seek emergency help immediately and arrange safe descent with assistance; do not let the person continue alone.
In China, call 120 for emergency medical help. Give the exact location, symptoms and a callback number. Ask your guide or hotel to help communicate if needed, but do not delay an urgent call while waiting for an office to open. English-language support and response times cannot be assumed.
Before travel, save the hotel address in Chinese, the receiving agency’s emergency contact and your insurer’s assistance number offline. For a remote extension, ask how transport to care will be arranged. Confirm that your insurance covers the planned altitude, activities and evacuation; the existence of a policy alone does not establish coverage.

Discuss medicines and oxygen with a clinician
Ask a qualified clinician whether preventive medication is appropriate for your route and health. Do not copy another traveller’s prescription or rely on a supplement as guaranteed prevention. Carry prescribed medicines with their instructions.
A hotel oxygen facility or oxygen on a train does not prove that it is safe to continue higher. Make sure your group knows the difference between a comfort facility and medical assessment. If illness changes the trip, prioritise care and let the receiving team handle the bookings afterwards.
