14. Temperature in the plane

According to research there is a connection between pressure and the temperature in the plane, and consciousness loss caused by a lack of oxygen usually referred to as hypoxia. The reason for this could be overheating of that air found in the plane’s cabin. As such, the pilots ensure that the temperatures in the aircraft are at the lowest levels which is why many complain of freezing in planes.

So the next time you’re flying, make sure you carry a warm jacket with you. In case you want to be even warmer, the warmest places in the plane are in the queue.
