Less oxygen with every metre
Above roughly 2,500 metres, the lower air pressure means each breath carries less oxygen. The body can adapt, but it needs time. Climbing too fast is the main cause of altitude sickness, which is why our itineraries build in gradual ascents and, on longer programmes, rest days.
Simple habits that help
- Walk slowly, even when you feel strong
- Drink regularly and eat well, even without much appetite
- Climb high during the day and sleep lower where the route allows
- Avoid alcohol in the first days at altitude
- Tell your guide about symptoms early; never hide them
Know the warning signs
Headache, nausea, dizziness, and unusual tiredness are common early signs. Our guides monitor the group closely, and descending is the most effective response if symptoms worsen. Ask your doctor for advice before travelling, especially if you have a medical condition or are considering medication.
