How atmospheric pressure affects humans?

1.High altitude are regions on the Earth's surface (or in its atmosphere) that are high above mean sea level. The pressure and temperature of the atmosphere at high altitude is substantially different than at sea level. These differences can affect living organisms, including humans.

2.Low barometric pressure also affects us, if for example we fly in an unpressurized aircraft. At 10,000 ft and above, the air is very thin and the lack of oxygen will affect our mind. Low air pressure can be very unpleasant for humans due to an absence of oxygen, so all areas of aircraft that contain passengers are artificially pressurized.

3.Some studies have also shown that atmospheric pressure can adversely affect human health, though many question whether the small natural variations caused, for example by weather front.

-A weather front is a boundary separating two air mass of different density, and is the principal cause of meteorological phenomenon. In surface weather analysis, fronts are depicted using various colored lines and symbols, depending on the type of fronts, are significant enough to affect humans.
