Don’t drink and trek

Trekking through the mountains can have serious risks. According to multiple government advice sources, those who plan to travel in high-altitude areas should take precautions against acute mountain sickness. The cause? Going too high too fast and not allowing the body to adjust to lowering levels of oxygen in the air. Alcohol can also exacerbate the condition, and in rare cases cause fatality.

Government advice for countries such as Peru, Nepal and even Andorra recommends that travelers should be physically fit, in good health and equipped with proper gear. They should also be aware of the risks, plan an itinerary that allows for acclimatization and follow professional advice. Traveling with an experienced guide is also recommended.

While government advice does not go into detail, there are many good online sources, such as the UK-based Travel Doctor website, that provide more information.
