Over the height of a human, say, the pressure will be equal in all directions.
Even so, even if there were a net downward pressure of the air, this will be a lot less than the gravity attraction on your mass.
And, most seem able to withstand gravity.

Why doesnt air pressure crush an empty soda can sitting on a table in your house?
Because the air pressure INSIDE the can is the same as the air pressure OUTSIDE the can !
Does air have no weight as a result of gravity?
Air does have a weight! And it is because of gravity! Note that this is per definition true because weight is only defined in the presence of gravity. Perhaps you are confused about why the air is up in the atmosphere and not down here on the ground with us? This has to do with air pressure. You see, materials don't like to be compressed, which is what gravity tries to do. Gravity tries to compress the air to the ground, but faces increased air pressure as it does so. Basically what happens is that the air particles repulse each other and thus tend to drive them apart. This force increases if you force the particles to be closer to each other. As gravity tries to pull air down, the air pressure increases which counter balances the pull of gravity. In the end a stable system is formed where the air pressure is highest down near the ground and lowest up in the upper lays of the atmosphere. The air particles up in the atmosphere do feel gravity, but if they would move down they would feel an increased air pressure which pushes them up again!
How and why does the air pressure change as you climb up a mountain?
all the air pressure goes down, so as you get higher up, there is less in the air
Is air pressure a push or pull force?
Yes resistance would be a push force.
How does barometric pressure vary with altitude?
pressure is a physical unit that measures what we may call the density of force i.e. trhe amount of force exerted on a certain area , the atmosphiric pressure is the force exerted by the air mass on a certain area , clearly more air means more mass , thus , when we go down the air above us increases , and when we go down the amount of air decreases.
Why does air in the atmosphere pressure down on us?
It is the pull of gravity on the column of air over you.
Why doesnt air pressure crush an empty soda can sitting on a table in your house?
Because the air pressure INSIDE the can is the same as the air pressure OUTSIDE the can !
How do you test an air pressure switch?
pull off the rubber hose suck or blow down it and see if a contact is made
What does high air pressure?
air pressure is the amount of air pushing down on you and high pressure is air that rises.
What is the major cause of air pressure?
The pull of gravity.
Why doesnt air pressure crush objects?
There is air pressure on all sides, inside or outside. The air pressure pushes on the object all ways and nothing falls. If you only apply pressure on the bottom then the object will lift. If you apply pressure on the top, the object will collapse. If air pressure is pushing side ways, the object will move sideways.
Is the weight of the air pressing down on the Earth?
Air pressure
What happens to the pressure and volume inside the thoracic cavity when you pull the rubber diaphragm down the lung model?
When the diaphragm is pulled down, the volume of the thoracic cavity increases, and the air pressure in the thoracic cavity decreases. This causes inhalation.
Great masses of air molecules pushing down from adove?
It is AIR PRESSURE!!
What is the weight of air pushing down?
the answer is air pressure
Where air pushing down with less pressure it is three words?
lower air pressure
What is a low-pressure system and what is a high-pressure system?
The difference is that Low air pressure has less air molecules pushing down in one area and high air pressure has more air molecules pushing down in one area.
