As one goes to high altitude? Pressure on the body increases or decreases? And why?

Question

Does it have to do with gravity? Or are pressure and gravity diferent forces?

Answer 1

Gravity is different, it's constant on Earth.
Imagine air pressure, as a column of air that reaches all the way up the atmosphere, pressing down on you. So at sea level, that column will be taller, than at high altitude. Hence, more pressure on your body at sea level than at high altitude.

Answer 2

As you go up
The pressure on the body decreases because The air becomes thinner and thus exerts less pressure

but u have not quite mentioned whether u want air pressure or overall pressure

so the force of gravity also decreases because then you are more distant from the centre of attraction

Answer 3

The more air above you, the more gravity pulls it down to create the 14 lbs of air preasure we experience. It is the same as if you had a column of air that went clear to space.

As you go up, the amount of air above you is reduced, and therefore the amount of preasure, while the gravity is pretty close to the same.

if you go 5 miles up, there is only 5 miles of air on top of you, and it is pretty thin, you might be at 4 lbs per square inch, because a column of air, 1 inch square would weigh 4 lbs from there to space. You and I would still weigh about the same. But the air would not be pulled down.
This is why you can get altitude sickness in Big Bear or in some mountains at 8,000 feet.

Answer 4

A good answer before me, but I can supply more detail.

The columnof air reaches up to space. In a column 1 cm2, the air weights about 1kg. This pressure (1kg / cm2) is known as a bar. Because of gravity acting on the air, the reduction with height is not linear. If you were to go up half way to space, the pressure would be lower that 0.5 bar.

Answer 5

The 122 sounds good however the 60 could be somewhat too low- possibly your healthcare expert can decrease the meds only abit to get the backside type up above 70- in many cases something below 60, you could desire to get lightheaded collectively as making use of or pass out!!!! so communicate on your MD suited away- I even have viewed blood pressures like 4 hundred++/one hundred fifty!!!! that is a hypertensive disaster!! however the guy unquestionably walked into the ER with a persistent headache and not something with a blood rigidity that top!! See a blood rigidity could desire to spike that top and reason a stroke, it is risky whether that's only as risky to have reasonably severe blood rigidity because of the indisputable fact that top rigidity continuously could desire to weaken the blood vessels on your head, eyes, and kidneys the place the blood vessels are incredibly fragile, and finally that could desire to hold approximately a stroke, blindness or kidney failure- so as subsequently blood rigidity could be stored the utmost around a hundred thirty-one hundred forty/80-ninety, something larger could desire to reason injury in the long-term

Answer 6

it decreases, because the temperature decreases, and also the density of air atoms decrases

Pressure and Gravity are two different kinds of Force.

Answer 7

The pressure increases and decreases relative to your frame of reference. From the viewpoint of outside preasure, it is decreasing. If your viewpoint is from the inside then the pressure is increasing.

MDP

Answer 8

it decreases because as you go up the temperature decreases and as given by the Gay-lussacs law that with the constant volume pressure is proportional to temperature

Answer 9

less pressure on the body allows more from the inside
