Taking a flight creates physical and emotional changes in us, something that is now being more extensively researched. Air travel can change our mood, make us emotionally weak (more crying) or sad, and even change how our senses work.

The factors responsible for this phenomenon are the high altitude, the reduced air pressure, inadequate oxygen going in the brain and overall anxiety associated with flying.

While we are on a flight, there are plenty of changes that we can experience:

• Change in brain chemistry and memory due to the deficiency in oxygen.
• Cognitive deficits in people who are already ill.
• Increased tiredness and more yawning during the flight.
• Deterioration in vision, dryness of skin, change in taste of food due to a reduction in the sensitivity of our taste buds and a decrease in the sense of smell.
• Change in air-pressure makes passengers generally uncomfortable with the sitting.
