Does A Link Exist Between High Altitudes And Longevity
No.: Studies done in the himalayas have been discredited because the poor written records of birth certificates. Ages are difficult to verify in those regions. Even said that nowadays is well known that hypothermia and low oxygen ( like in high place ) causes hibernation of cells in the body putting them under inanimated suspension preventing cellular damage and cell death. See what others have to say. ...Read moreSee 1 more doctor answer
As one ascends through the atmosphere, every breath contains fewer molecules of oxygen. One must work harder to obtain oxygen, by breathing faster and deeper. The % of oxygen in the atmosphere at sea level is 21%. As altitude increases, the % remains the same but the number of oxygen molecules per breath is reduced. At 12, 000 feet 40% fewer oxygen molecules per breath. Your ...Read more
Can high altitude cause hypertension or aggravate it if it already exists? If so what causes this?
No, Internal Control: Bp: a result of cardiac output vs. Average resistance of the 20, 000 to 30, 000 end arteries (arterioles) which determine blood flow to each capillary bed, both co ; size of all arterioles (degree of constriction) are under split-second control from brain ; constantly being adjusted. BP is just a momentary result. Brain integrates many variables, including perceptions/feelings ; adjusts accordingly. ...Read more
Good BP until living @ high altitude then a year later things spiralled out of control. When back @ sea level didn't need meds. Altitude reaction?
Spaced out Air!: As one ascends through the atmosphere, every breath contains fewer molecules of oxygen. One must work harder to obtain oxygen, by breathing faster and deeper. The % of oxygen in the atmosphere at sea level is 21%. As altitude increases, the % remains the same but the number of oxygen molecules per breath is reduced. At 12, 000 feet 40% fewer oxygen molecules per breath. Your body has to cope! ...Read moreSee 1 more doctor answer
Adapt and overcome.: The human body is pretty flexible and adaptable if changes are not too drastic or demanding. Anyone can live at high altitude if they acclimate slowly. La rinconada in peru has 30, 000 inhabitants at 16, 728 ft above sea level. Their bodies produce extra red blood cells to compensate for the reduced pressure of oxygen. ...Read more

When you visit, you need to make more compensations, but if you stay for more than a few weeks, your body will do it on its own for the most part.People may feel affects from higher altitudes as low as 4000 ft above sea level. Usually by 6000 ft, they will experience more fatigue. ...Read more
Prepare first,go slo: It is important to acclimate to elevation by lessening activity at the start. . Since oxygen levels are lower at elevation, we tend to hyperventilate to maintain oxygen levels. Use of acetazolamide a diuretic can be started prior to going to elevation to cause mild hyperventilation making acclimization easier. Hydration and avoidance of excess alcolhol prior to acclimating is helpful. ...Read more
Many changes: 1. You breath faster to compensate for the thinned density of oxygen. 2 body makes more oxygen carrying red cells at altitude 3. Kidneys put out more bicarbonate to keep your acid base state adjusted. Your rapid breathing blows off carbon dioxide and your kidneys adjust for this change but it takes a few days to body to alter. There are medicines to speed this acclimatization. ...Read more
Certainly, Examples:: 1.Your bone marrow will makes more oxygen carrying red cells at altitude 2.The body produces more of a particular enzyme which increases release of oxygen from hemoglobin to the body tissues 3.Your kidneys adjust the acid base state of your body by changing amount bicarbonate excreted. 4. Pulmonary capillary pressure increases, forcing parts of the lung to work that are dormant at sea level. ...Read more
