Why you do not feel air pressure although there is a tall column of air above us?

If the human body was hollow and contained a vacuum, we would then feel the air pressure. However, our lungs contain air, so the internal pressure is the same as the external pressure. Air pressure is perfectly balanced everywhere it is in contact with us, and all of our internal fluids, blood, lymph, etc., are under pressure, and balance the pressure that the air exerts. If a human being were to be exposed to the vacuum of outer space, our pressurized internal fluids would explode. We can only feel a difference in pressure, we do not feel perfectly balanced pressures, within and without.

Why atmospheric pressure nearest to the earth surface?
Imagine this scenario: a pyramid of cheerleaders. The ones at the bottom feel more pressure, because there's more people on top. The ones on top feel less pressure because there's less stuff on top of them. Now think about your question, if you're @ the bottom, there's more stuff on top of you.
How does atmospheric pressure change with height?
Think of the air pressure on any horizontal surface as the weight of all the air above it, all the way to the top of the atmosphere. As you increase altitude (go higher, on a mountain or in an airplane), there is steadily less atmosphere above you, and the air pressure steadily decreases with altitude.
Is the throat inferior to the shoulders?
No. It is above the shoulders. Feel it and you will see that is is superior.
Why do you not notice atmospheric pressure on your body?
We do not feel the atmospheric pressure - roughly 101kPa - because our bodies have adapted to it, to the point where the pressure in our bodies exactly balances the external pressure, resulting in no net force on your body.
Why is there no pressure on your body?
We do not feel net pressure on our body, since the pressure imposed on our body by atmosphere is equal to our body's blood pressure. That why we do not feel any pressure on our body. But if go inside deep in the sea, or above mountains of significant hight, then we start feeling either lack of pressure or more pressure. And start getting problems due to unbalance of pressure, and related diseases.
Would a fly flying inside an aeroplane add to its weight?
No. A fly hovering above you doesn't make you feel heavier does it? Although you probably would'NT feel it anyway.
How will a person feel liquid pressure as she goes at different depths in a swimming pool?
the deeper she goes there is more weight above her thus greater pressure which results to pain in the eardrums
When was Feel the Pressure created?
Feel the Pressure was created on 2010-08-23.
If water pressure does not change why does it feel like more pressure when it comes out of the shower head?
Although water pressure is constant, when other pressure is put on it, air for instance it will be forced through an open. this is much like an aerosol or propellant filled can that forces product out of the container.

How do submersible pumps work?
While it's easy to push on water, it's hard to pull on water. When you drink soda through a straw, you may feel like you're pulling on the water, but you're not. What you are actually doing is removing some air from the space inside the straw and above the water, so that the air pressure in that space drops below atmospheric pressure. The water column near the bottom of the straw then experiences a pressure imbalance: the usual atmospheric pressure below it and less-than-atmospheric pressure above it. That imbalance provides a modest upward force on the water column and pushes it up into your mouth. So far, so good. But if you make that straw longer, you'll need to suck harder. That's because as the column of water gets taller, it gets heavier. It needs a more severe pressure imbalance to push it upward and support it. By the time the straw and water column get to be about 40 feet tall, you'll need to suck every bit of air out from inside the straw because the pressure imbalance needed to support a 40-foot column of water is approximately one atmosphere of pressure. If the straw is taller than 40 feet, you're simply out of luck. Even if you remove all the air from within the straw, the atmospheric pressure of the water below the straw won't be able to push the water up the straw higher than about 40 feet. To get the water to rise higher in the straw, you'll need to install a pump at the bottom, or a submersible pump. The pump increases the water pressure there to more than 1 atmosphere, so that there is a bigger pressure imbalance available and therefore the possibility of supporting a taller column of water. The submersible pump can boost the water pressure well above atmospheric and thereby push the water to the surface despite the great height and weight of the water column. Multiple stage submersible pumps are arranged in series so that the discharge from the first stage becomes the intake for the next stage with each successive stage adding its pressure to the previous one. Surface suction pumps are really only practical for water that's a few feet below the surface; after that, deep pressure pumps are a much better idea.

What changes in air pressure would you expect if you carried barometer down a mineshaft?
the air pressure would increase because the amount of atmosphere above you increases
What is the definition of atmospheric pressure?
Air pressure is the force (weight of Earth's atmosphere) exerted on you by the weight of tiny particles of air, the air molecules above and around you. This is also referred to as "barometric pressure" (measured with a barometer) and will change with altitude or elevation. The standard pressure is 1 ATM (atmosphere), equal to 101325 pascals or 1013.25 mbar.
What causes pressure above the eyebrows on the entire forehead but does not feel like a headache just the pressure?
Pressure in the head can be many things, including a mild tension headache. It may also be related to an allergy, as there are sinus cavities above the eyebrows, or hypertension. It the pressure does not resolve within a few days, or if you begin to have blurred vision or other neurological symptoms, you definitely need to see a doctor to get it checked out, possibly emergency care.
What does it mean when you feel cramping a litte above your pelvic area and it feels like a lump and when you put pressure on it it hurts a little bit?
I have this problem too, it might be a cavity.
