"If a occurs during an emergency landing, the heat can cause these fabrics to melt onto the skin or result in severe burns."

The need for rapid evacuation is crucial. Ms Negroni states that in the event of a fire on board, survival may depend on our ability to escape quickly, which could be hindered if we suffer burns on our legs due to wearing leggings.

There are also vascular health concerns. Stylist Patrick Kenger adds that compressive leggings can impede mobility during long . Such garments might even restrict breathing and exert constant pressure on the skin.

Dr Hugh Pabarue warns that this could lead to deep vein thrombosis: "Wearing leggings and other restrictive garments such as skinny jeans that are too tight reduces blood's ability to flow into and out of the legs."

Although the average passenger's odds of developing a or other serious condition are low, it is still worth keeping your general health in mind as you travel.

If travelling by plane, it is best to wear loose-fitting, breathable clothing made of natural fabrics such as cotton. Shoes should also be kept on during take-off and landing to facilitate easy evacuation if necessary. Only high heels must be removed in the event of the evacuation slide being used.
