Running and Altitude Sickness


When it comes to running, nothing beats the scenic views and the exhilarating sense of adventure that comes with high-altitude trails. However, high altitudes can present certain challenges. One such hurdle is altitude sickness, a topic that warrants discussion for anyone planning to take their runs up a notch, literally.

Altitude sickness, also known as Acute Mountain Sickness (AMS), occurs when you cannot get enough oxygen from the air at high altitudes. This can result from rapid exposure to low amounts of oxygen at high elevations. Runners, especially endurance runners, are prone to AMS, hence understanding its effects on your performance and health is critical.

Recognizing the Symptoms of Altitude Sickness

Identifying AMS symptoms early can be lifesaving. Symptoms usually appear within hours after arrival at high altitude and may resemble a hangover – nausea, headache, and fatigue. Other signs such as dizziness, lightheadedness, decreased appetite, shortness of breath, rapid pulse, and sleep disturbances may also be evident.

Altitude Sickness and Running Performance

When you run at high altitudes, the air is ""thinner"", meaning it has less oxygen and pressure than at sea level. The body, in turn, has to work harder to deliver the necessary oxygen to your muscles, which can affect your performance. It could negatively impact your strength, speed, and endurance, hampering your running momentum.

Acclimatization: The Key to High-Altitude Running

Experts recommend slow and gradual acclimatization before venturing into high altitude runs. This process includes spending a few days to weeks at intermediate altitudes allowing your body to adjust to the less oxygen-rich environment. Consider doing lower intensity workouts initially before increasing the intensity and duration.

Preventing Altitude Sickness: Hydration and Nutrition

Staying hydrated is critical during high-altitude runs. The body tends to lose more fluids through respiration in thin air environments, increasing the risk of dehydration. Remember to consume electrolyte-filled drinks to replace the lost minerals and salts during perspiration. Proper nutrition also helps the body cope better with high altitude stress. Consume carbohydrates-rich foods as they are easier to convert into energy.

Running in high-altitude locations can be a thrilling experience, but understanding the health implications, particularly altitude sickness, is essential. Always remember to listen to your body. If the symptoms of AMS set in, there’s no shame in descending to a lower altitude. Happy high-altitude running!
