Sarah Morgan, founder and CEO of the app VitaminIQ, suggested wearing blue-light-blocking glasses in the airport and on the plane.
"Have you ever seen someone walking around with rose- or yellow-tinted glasses? They're becoming more popular because they block stimulating blue light from entering our brains and telling us to wake up and be alert," Morgan said.
Blocking blue light and flooding your brain with red light allows the body to receive a calming signal to relax and rest, which in turn helps recover faster from jet lag, Morgan said.
Besides stimulating the brain, blue light also suppresses the body's production of melatonin, the hormone your body produces to help make you sleepy. If you're not up to wearing blue-light-blocking glasses, avoid phone and computer screens and in-flight TVs, all of which emit blue light.
