Do High Altitudes Hold the Key to a Longer Life?

Updated: Jun 1

Have you ever wondered why some of the world’s oldest civilizations, like the Andeans and Tibetans, chose to live way up in the mountains?


It’s not just for the breathtaking views! These high-altitude habitats have been home to people for thousands of years, and there might just be some health secrets hidden in those lofty peaks.

Understanding how the body works at high altitude


Have you ever thought about what "high altitude" really means?


Basically, we're talking about heights that are higher than 2,500 meters (8,200 feet). As you go up, the air gets thinner.


This means that each breath you take gives you less oxygen. It sounds hard, doesn't it? You body, on the other hand, has some pretty cool ways to deal with these.


Effects of High Altitude on the Body


Your body changes in interesting ways when you're up there, above everything else. Your blood has changed in a big way. There are more red blood cells in your blood, which means that the hematocrit levels start to rise.


That's just how your body deals with the thinner air. Even though there is less oxygen in the air, your blood can carry more oxygen if you have more red blood cells.


Advantages of Having More Hemoglobin at High Altitudes


Now, hemoglobin is the protein in your blood cells that keeps oxygen in. When you're at a high elevation, your body makes more hemoglobin to get the most oxygen and send it to all parts of your body. A study in the Journal of Applied Physiology says that this increase in hemoglobin is very important.


It makes it a lot easier for your body to get oxygen to your muscles and cells, which helps them work at their best even when the air is thin. This is very important if you live or play in the woods and want to keep your health and energy up.


And even though living at high elevations might seem hard, our bodies are very good at adjusting to handle it. Making the most of what you have is important.



Benefits of High Altitude Living


Cardiovascular Health at High Altitude

First up, your heart. Living high above sea level can actually be a big win for your heart health. Studies have shown that people living at higher altitudes have a lower chance of dying from heart disease.


This isn't just mountain talk—researchers think that the "thinner" air might help train your heart to be more efficient, reducing stress on it and helping to fend off heart disease. It's like your heart is hitting the gym without you even knowing!


Keeping Fit and Fighting Obesity


You might find it easier to stay lean at higher elevations. A piece in the International Journal of Obesity points out that folks living at high altitudes tend to have lower obesity rates.


This could be because your body works harder in thinner air, burning more calories even when you’re just going about your daily business. Plus, the active lifestyle that often comes with living in mountainous areas means you're more likely to keep moving and stay fit.


Mental Health Benefits of High Altitude


According to the Gallup Well-Being Index, being active and having strong community ties, which are common in high-altitude towns, are key for mental health.


The scenic views and the close-knit community vibe can really boost your mood and overall mental health. It’s about more than just fresh air— it’s about feeling connected and alive.


So, whether it’s boosting your heart health, helping maintain a healthy weight, or enhancing your mental well-being, living at high altitudes offers some pretty impressive health benefits.



The Hunza Community: Where People Live to 100



Have you ever heard about the Hunza community? These folks live in the mountains of Northern Pakistan and they’ve got a reputation for living really long, healthy lives.


It’s fascinating to see how their lifestyle choices stack up against what we know about health and longevity.


Hunza Longevity Secrets


Let’s start with their incredible longevity. It’s said that many Hunza people live to be over 100 years old. But what’s their secret? Well, a lot of it comes down to their diet and lifestyle.


Diet of the Hunza People


Nutritionally, the Hunza diet is a powerhouse. They consume a variety of foods rich in vitamins and minerals, particularly apricots, which are a staple for them.


Apricots are high in Vitamin A and dietary fiber, which are great for maintaining good health. The Hunza also eat plenty of leafy greens, root vegetables, and nuts, all of which contribute to their robust health profile.


Separating Myth from Science


Now, let’s tackle the myths versus the science. While the Hunza are often spotlighted for their supposed centenarian population, it’s important to approach these claims with a balanced view.


Scientifically, while their healthy diet and active lifestyle certainly contribute to longevity, genetic factors and the low stress of mountain living also play a significant role.


Additionally, record-keeping in these regions isn’t always as precise as in other parts of the world, which can sometimes lead to exaggerations about age.


In reality, the combination of diet, exercise, environment, and perhaps a bit of genetic fortune, all contribute to the health benefits observed in the Hunza community.


It's a fantastic case study of how integrating simple, whole foods into your diet and maintaining an active, community-oriented lifestyle can have profound effects on health and longevity.



Comparative Health Impacts: High vs. Low Altitude


First off, let's chat about heart health. According to data from the American Heart Association, folks living at higher altitudes often show better cardiovascular metrics.


This includes things like lower rates of heart disease and hypertension. It seems that the heart can benefit from the extra work it does in thinner air, getting a sort of natural 'workout' from just dealing with the daily grind up high.


But what about people at lower altitudes? Well, while they might not get that 'natural workout' from the altitude, they often have easier access to healthcare services and less environmental stress (think less UV exposure and less strain from low oxygen levels), which balances things out in different ways.


Adaptation and Natural Selection


Now, adapting to high altitudes isn't a walk in the park. It involves some pretty neat biological tweaks. For instance, people who have lived in these areas for generations have developed certain genetic adaptations that help them cope better with lower oxygen levels.


These adaptations can include increased lung capacity and more efficient blood oxygen utilization. It’s a brilliant example of natural selection at work, helping humans thrive in challenging environments.

Conclusion


In conclusion, the allure of high-altitude living extends beyond the immediate appeal of stunning landscapes and a sense of seclusion. As seen through the example of ancient civilizations like the Andeans and Tibetans, as well as the remarkably long-lived Hunza community, life at higher elevations offers a unique concoction of health benefits that seem to play a significant role in promoting longevity and well-being.


The physiological adjustments our bodies make to cope with thinner air, such as increased hemoglobin levels and a higher count of red blood cells, are not just responses to the challenges of high-altitude living; they are enhancements that fortify our cardiovascular health, assist in maintaining a healthy weight, and may even bolster our mental health through the sheer necessity of an active, community-centric lifestyle.


This, combined with the dietary habits and active lifestyle of communities like the Hunza, showcases a holistic approach to health that mirrors the advice of modern wellness advocates: eat a balanced diet rich in natural foods, remain physically active, and nurture strong social bonds.


While the scientific community maintains a balanced view on the direct causality between high-altitude living and an increased lifespan, incorporating elements from these high-altitude lifestyles could have universally beneficial impacts. The comparative health outcomes of high versus low altitude residents underscore the importance of our environment in shaping our health, yet also remind us of the adaptability of the human body and the potential benefits of incorporating natural physical challenges into our lives.
