hiiiiii the blanket of air around earth's surface know as atmosphere,
it contains so many gases like....oxygen carbon dioxide,,,, and so mamy others..and these are so neccesary to survive any where

Air pressure is also known as atmospheric pressure. Some common use of air pressure in daily life is inflating tires, playing musical wind instruments, drinking through straw, flushing toilet, drawing water from well, operating barometer, blowing up balloon, breathing, maintaining body shape especially abdomen.
When drinking with a straw, one has to suck the straw. This causes the pressure in hte straw to decrease.
The external atmospheric pressure, which is greater, will then act on the surface of the water in the glass, causing it to rise through the straw.
Vacuum Cleaner applies the principle of atmospheric pressure to remove dust particles. When it is switched on, the fan sucks out the air from space inside the vacuum (space A). Space A then becomes a partial vacuum.
The atmospheric pressure outside, which is greater, then forces air and dust particles into the filter bag. This traps the dust particles but allows the air to flow through an exit ath the back.
Altitude training
At high altitudes (1500m and above), there is still approximately 21% of oxygen in the air, but due to the low atmospheric pressure (B < A), the partial pressure of oxygen is reduced. Due to the pressure gradient, significantly more energy is also required for the lungs to take in oxygen. Hence, to adapt to the difficulty of obtaining and lack of oxygen, the body will increase the mass of red blood cells and hemoglobin in the blood, as well as reduce muscle metabolism to enable a more efficient use of oxygen. This effect is able to last for up to 2 weeks after returning to lower altitudes giving altitude trained athletes a competitive advantage.
ILLNESS
When the atmospheric pressure drops, tissues expand. The expansion of tissues in and surrounding joints aggravates the nerves, causing pain. Thus, patients living in geographical locations with a higher atmospheric pressure tend to experience a greater severity of osteoarthritis (pain in the joints due to expansion of tissues).
Drops in atmospheric pressure also have an impact on headaches, particularly sinus headaches. When atmospheric pressure drops (such as in an ascending airplane or before a storm), gases in the sinuses and ears are at a higher pressure than those of the surrounding air. The air pressure tries to equalize, causing pain in the face and ears. Those that suffer from chronic sinusitis or have a cold have the most issues, as the air becomes trapped in the sinuses and is unable to equalize.
Effects of high atmospheric pressure
Illnesses
Increases in atmospheric pressure (such as in a descending airplane) results in a condition called “ear popping” where air particles rushes into the ears to balance out the pressure inside and outside of the ears. This may result in pain for some people.
Other health effects of high pressures such as that during diving could be found at Effects of Hydrostatic Pressure on the human body.
