New airline seats could provide individualized climate controls

The video explains how airplane cabins circulate air by using compressed air from jet engines, which is then cooled and fed back into the cabin. This process results in low humidity, causing discomfort for some passengers, with symptoms like headaches and dry eyes. Researchers are developing new seat designs that offer individualized climate control by drawing heat and moisture from the body and adjusting humidity around the neck.
