Dangers of Training at High Elevation: What to Know?

Altitude Sickness Risks

Altitude sickness occurs when the body cannot adapt to the lower air pressure at high elevations. Symptoms include headaches, nausea, fatigue, and shortness of breath. To mitigate this risk, ascend to high elevations gradually, allowing the body to adapt to the changing conditions. A safe ascent rate is 1,000 to 1,500 feet per day, with rest days as needed. For example, ascending to 8,000 feet in one day can lead to severe altitude sickness.

Dehydration and Heat Exhaustion

At high elevations, the air is drier, increasing the risk of dehydration. To combat this, drink at least 2-3 liters of water per day, and consider using a hydration pack. Monitor body temperature closely, as heat exhaustion can occur rapidly. Take regular breaks in shaded areas to cool off, and use cooling towels or bandanas to lower body temperature. For example, a body temperature of 102°F (39°C) can lead to heat exhaustion.

Performance and Injury Risks

High elevation training can also lead to decreased performance and increased risk of injury. The lower air pressure and humidity can cause muscles to cramp, and the body’s increased effort to breathe can lead to fatigue. To minimize these risks, incorporate strength training and flexibility exercises into your routine to build resilience. Consider training at high elevations during the cooler morning hours, when the air is less dense. For example, training at 6 AM at 8,000 feet can reduce the risk of heat exhaustion and improve performance.
