On the ground, the airplane is unpressurized and the outflow valve is wide open. During preflight, the pilot sets the cruise altitude on a cabin pressure controller. As soon as the weight is off the main wheels at takeoff, the outflow valve begins to close and the cabin starts to pressurize.

Airplanes can be breeding grounds for bacteria and viruses, from cramped conditions to the low humidity that characterizes the air circulating on board. Low humidity can dry out your nasal passages and irritate your throat.

However, in certain circumstances, such as on a plane, the brain can get confused as your eyes will indicate that you are not moving while your inner ear will perceive the fact that you are actually moving through space at incredibly high speeds. It is this dissonance that cause symptoms such as nausea and dizziness.
