The comfy item you shouldn't wear if you're traveling by plane, according to an expert: "It's a risk."

Comfort is essential when traveling on any type of transport , especially when the journey lasts for hours. However, there is one basic item of clothing, chosen by many travelers, that could put you in danger.

The moment you choose what to wear while traveling could save your life , even though it may seem difficult to imagine. This is according to aviation safety specialist Christine Negroni, who gave an interview to HuffPost .

The expert stated that leggings , a garment most commonly used by the population, are made with synthetic fibers derived from petroleum and are highly flammable.

For his part, the specialist warns that "if a fire breaks out during an emergency landing, the heat can cause these fabrics to melt onto the skin or cause severe burns . It's a risk."

But fire isn't the only thing that could cause problems in the event of a fire accident, as this garment can cause damage to vascular health by impairing leg mobility .

Leggings, by pressing on the skin for so long, can also impair breathing and blood circulation, and can even lead to blood clots.
