#1 – Skinny jeans
If you interview experienced travelers about what they think of wearing skinny jeans on a plane, they’ll either give you a blank look and walk away or smile sagely and tell you this:
Due to the low air pressure, and therefore lower oxygen levels in the plane cabin, wearing tight clothes like skinny jeans is a bad idea. Why?
Because skinny jeans or any tight pieces of clothing restrict your blood flow and increase your risk of deep vein thrombosis, a blood clot that usually develops in legs, especially during long-haul flights.
That is why doctors recommend wearing loose-fitting clothes made of cotton for your utmost comfort and well-being.
If you’re pregnant, wear baggy trousers with drawstrings or an elastic waistband, in addition to compression socks which reduce the risk of poor blood circulation and swelling, unlike regular socks or stockings that are too tight.
