Spoiler alert: Sitting for hours on an airplane will make you feel like sh*t. OK, no spoilers there. That's obvious. But there are a couple simple tricks that can help with both circulation and the inevitable soreness you'll feel after a long flight.
Cardiology fellow at Boston's Brigham and Women’s Hospital Dr. Aaron Aday recently revealed to Conde Nast some good tips for alleviating circulation problems when flying. His tips, coupled with some notable pre-boarding stretches, should help you survive that flight to Paris and come out ready to take on that walking tour, or at least in better shape for that walking tour.
First, Dr. Aday says you should get up once every hour when in the air, which means it would be helpful to book the aisle seat. While seated, Aday suggests doing little stretches like flexing and relaxing your calf muscles, rolling ankles, and clenching and spreading toes. This will all help to get the blood flowing.
