This temperature variation highlights the importance of dressing in layers when spending time in Machu Picchu, both in the mountains and in towns like Aguas Calientes at the foot of the ruins.

    Study on Temperature and Physiological Adaptation in High-Altitude Environments

    • A study examining the effects of temperature on human physiology at high altitude found that exposure to cold temperatures can lead to an increased metabolic rate, which helps the body to maintain thermal homeostasis. This increased metabolism can provide energy needed for muscle and brain function, but it can also be an energy burden on the body. To adapt to extreme cold temperatures, the body undergoes several physiological changes, including vasoconstriction, where the blood vessels narrow, reducing blood flow and heat loss.

    Additionally, a study noted that acclimatization to high altitude and low temperatures is crucial for individuals visiting Machu Picchu or similar locations. Acclimatization allows the body to adjust to new circumstances by changing physiological responses to the environment, helping individuals to conserve energy, maintain body temperature, and prevent hypothermia or other related health issues. This includes adjusting metabolic rate, improving blood flow and oxygenation, and increasing red blood cell production to cope with the demands of high altitude.

    A research paper published in Nature highlights the importance of gradual acclimatization to high altitude, stating that individuals who ascend rapidly to high altitude may experience more pronounced negative effects, such as reduced cognitive function, impaired physical performance, and a higher risk of dehydration and other health issues.
