Medical figures have insisted there is a reason why you may feel more tearful when you're 38000 feet in the air as you can suffer from hypoxia, which can make certain people feel more weepy.
Dr. Robert L. Quigley, senior vice president and regional medical director of International SOS & MedAire, said: "At every age level, across genders, religions, races and backgrounds, many people have one of the baseline mental illnesses, from claustrophobia to agoraphobia, and other various manifestations of anxiety - they're ubiquitous. The stresses of travel are enough to trigger anyone who has a baseline mental health challenge ... There's a plethora of evidence that you go into a relative state of hypoxia [oxygen deficiency] when you're in flight. One person might feel weepy, another sleepy -- hypoxia affects people in different ways. There may even be hormones triggered by hypoxia -- it's all idiosyncratic."
And being in a smaller physical space can also increase anxiety and cause you to have a teary trip.
Dr. Jodi De Luca, a Colorado-based licensed clinical psychologist, added: "The smaller seating arrangement increases anxiety - your basic physical boundaries are encroached. It's not comforting to fly anymore. Our basic needs - food and drink, blankets and pillows, aren't provided for. You're even limited to how much you can bring on-board to comfort yourself."
