Worldwide , more than 80 million peoplelive at least 8,202 infantry ( 2,500 beat ) above ocean stage , mainly in South America , Central Asia and East Africa .
Some of thehighest lasting settlementsinclude Wenquan inChina ’s Qinghai responsibility , at a astonishing 15,980 metrical foot ( 4,870 m ) above sea level , and Korzok in India , around 15,000 ft ( 4,572 m ) above ocean level .
La Rinconada in Peru is the highest permanent settlement on Earth, situated between 16,000 and 17,000 feet (4,900 and 5,200 meters) above sea level.
However , one plaza towers above them all . nestle in the Peruvian Andes is a township that is nicknamed " Devil ’s Paradise . " Officially named La Rinconada , its 50,000 habitant live between 16,404 foot ( 5,000 m ) and 17,388 feet ( 5,300 m ) above sea story , making it the highest permanent liquidation on Earth .
lifetime in La Rinconada is extremely difficult . There isno running water , sewage system or garbage disposal . intellectual nourishment is imported from lower EL regions and electricity was only set up in the Ithiel Town in the 2000s .
The townspeople is known for Au mining , having started out as a temporary minelaying settlementmore than 60 years ago . But the price of atomic number 79 is that habitant must live in extreme conditions with up to half the oxygen pressure that exists at sea grade .

Mountain sickness
If you were not born at high altitude and ventured to EL like that of La Rinconada , one of the first change that you ’d discover is your external respiration pace andheart rategoing up . This is because less atomic number 8 is uncommitted in the air , so the lungs and heart need to work harder to nurture tissue .
" By the time you ’re at about 4500 cadence [ 14,763 foot ] , the same breather of air travel that you take here [ at sea level ] has about 60 % of the oxygen molecules , so that ’s a bounteous stress,“Cynthia Beall , a prof emerita of anthropology at Case Western Reserve University in Ohio , secern Live Science .
At first , the portion ofhemoglobin — the protein within red rakehell cellphone that post oxygen — in the pedigree would also plummet , Beall said . The high the altitude , the stronger all these response would be , she say .
A village at 11,480 feet (3,500 meters) in the Simien Mountains of Ethiopia.
Some people may develop a condition calledacute mountain sickness(AMS ) as the consistence endeavor to correct to lower oxygen levels . This can have symptom such as headaches , tiredness , nausea and a loss of appetite .
commonly after about a week or two at gamey EL , a person ’s heart rate and breathing will quieten down slightly as the body begins to make more red lineage cells and hemoglobin to compensate for the downhearted oxygen levels in the air , Beall said .
Adapting to altitude
However , highlanders , like those living in La Rinconada , have on the face of it adapted to low-spirited - oxygen environments in many ways .
" There ’s pretty good grounds from around the world that there are either slight or very largeincreases in lung volumefor people who are display to high altitude , particularly before adolescence , " Beall say .
Andean highlanders , for exercise , generally have ahigh concentration of hemoglobinin their rakehell which makes their blood thicker . While this countenance Andeans to carry more oxygen in their profligate , it also means that theyare vulnerableto developing a condition called continuing mountain malady ( CMS ) . This happens when the body producesan excessive amountof red lineage cells .
CMS can go on to masses who live at altitudeshigher than 10,000 feet(3,050 m ) for many months or years and causes symptoms such as fatigue , shortness of breath and aches and pains . Around one in four people in La Rinconada are guess to suffer from CMS .
The best intervention for CMS is to go to a lower EL , Tatum Simonson , an associate prof of medicinal drug at the University of California , San Diego , told Live Science . However , this is n’t always a workable root if someone has their whole livelihood in a special region , she sound out . unconstipated bloodletting and need a drug called acetazolamide , which reduce ruby line of descent cell product , may provide some relieffor patients with CMS , although the safety and efficaciousness of these treatment in the long run is still unsung .

Tibetan highlanders , on the other bridge player , despite also living at high altitudes , don’t have elevated hemoglobin concentrationsand are therefore atlow risk of infection of grow CMS . or else , they ’re believed to have adapt to low - O environments by havinga higher blood flowthrough their trunk , Beall said .
Specifically , Tibetans transport a mutation in a gene calledEPAS1that lowers the amount of hemoglobin in the blood . This mutation is believed to have beeninherited fromour extinct human cousins , the Denisovans . Mutations in EPAS1 have alsorecently been foundin a mathematical group of Andean highlanders , which scientists are now trying to investigate further .
