Altitude Sickness Behind the Wheel: Prevention and Safety
Driving through the Andes is an unparalleled visual experience, but Altitude Sickness (Soroche) can turn a pleasant trip into an unnecessary risk.
Ascending above 3,000 meters (approx. 10,000 feet) reduces available oxygen pressure. For a driver, this doesn't just mean physical fatigue; it leads to slower reaction times and decreased concentration. Understanding how your body reacts is your first line of defense.
Prevention: Preparing Your Body
The key isn't curing altitude sickness, but preventing it from appearing. A hydrated and well-nourished body processes the lack of oxygen much better during long climbs.
Essential Recommendations
Constant Hydration: Drink water even if you aren't thirsty. High altitude dehydrates you quickly through respiration.
Light Meals: Avoid fatty or heavy foods before ascending. Digestion is much slower at high altitudes and consumes vital energy.
The Power of Coca: Coca tea or chewing the leaf (chacchar) helps oxygenation naturally without affecting your reflexes.
What to Do if You Feel Dizzy While Driving
The first symptom is usually a slight throbbing headache, followed by heavy eyelids or dizziness. Never try to "tough it out" until the next town if symptoms appear.
Emergency Driving Protocol
- Pull over immediately: Find a safe spot off the road. Turn on your hazard lights.
- Breathe deeply: Take long inhalations through your nose and exhale slowly. This helps calm the nervous system.
- Portable Oxygen: It is highly recommended to carry a small oxygen canister (oxygen shot) in the glove box for emergencies.
- Switch drivers: If traveling with others, it's time to hand over the wheel. If alone, wait at least 20 minutes before attempting to descend.
Finally, remember that altitude isn't negotiated; it's respected. Ascending gradually and taking breaks at intermediate points is the best technique to enjoy the world's finest views without putting your life at risk.
