嗯啦
If someone teleported from sea level to the top of mount evers
Things would go bad fast at an altitude of eight thousand eight hundred forty eight meters
Berometric pressure is approximately thirty three percent of what it is at sea level
This means there's significantly less oxygen in the air and our proxiported individual would likely suffocate in minutes
However for people that make this same journey over the course of a month
It's possible to survive at the peak for hours
So what can happen to our bodies in just one month
That allows us to endure this incredible altitude
Let's imagine you're one of the five point eight billion people living less than five hundred meters above sea level
When you take a breath at this altitude
Your lungs fill up with air composed of numerous gases and compounds most important among needs are oxygen molecules
Which bond to the hemogloban in your red blood cells blood then circulates throughout your body bringing essential oxygen to all yourselves
But as altitude increases the air starts to get thiner the relative amounts of each compound remain the same well into the upper atmosphere
But overall there's less oxygen for our bodies to absorb
And if you assent to altitudes above two thousand five hundred meters
The resulting oxygen deprivation can cause a form of altitude sickness known as ams often causing headaches
Fatigue and nosia fortunately ams only happens
When we asend too fast
Because our bodies have numerous ways of adapting to high altitude within minutes or even seconds of reaching altitude of one thousand five hundred meters krodted chemo receptors in your neck sense your bloods low oxygen pressure
This triggers ers responbto
That increases the rate and depth of your breathing to counteract the lack of oxygen
Your heart rate also increases and your cart contracts more typly to pump additional blood with each b quickly moving oxyinated blood around your body
All these changes happen relatively fast
And if you were to keep assending your heart rate and breathing would speed up
Accordingly
But if you stayed this altitude for several weeks
You could reap the benefits of some longer term adaptations within the first few days above one thousand five hundred meters
The volume of plasma in your blood decreases
Which increases the concentration of humo globan over the next two weeks
Your hemogloban levels will continue to rise allowing your blood to carry even more oxygen per mililater paired with your high heart rate
This new hemogloban rich blood efficiently distributes oxygen throughout your body so much
So that the volume of blood being pumped with each heart beat can return to normal levels over the same time
Your breathing also increases even further in a process called ventilatory aclimmatization
然后after this several weeks of extended acclimatization
Your body has made enough significant changes to climb even higher
However you'll still have to spend additional time aclamating along the way often climbing back down to recover before a sending even higher
Because the summit erest isn't just high
It's the highest place on earth
And that tititutuabove three thousand five hundred meters
Our bodies are under incredible ble stress orteries in vains in the brain dilate to speed up bloodflow
But our smallest blood vessels called capitariies remain the same size
This increased pressure can cause blood vessels to leak and and fu id to builup in the brain
A similar issue can occur in the lungs
Where low oxygen causes blood vessels to constrct leading to more leaking vessels and fluid build up
These two conditions known as case and heap respectively are incredibly rare
But can be life threatening
If not dealt with quickly some to debetons and south americans with family histories of living at high altitude have genetic advantages
That can prevent minor altitude sickness
But even they are immune to these severe conditions yet despite these risks
Climbers over the last century have proved people can go higher than scientists ever thought possible pushing past their bodies limitations
These climbers have redefined what humanity can adapt to
