1. Your immunity is important!
Boost your immunity and proactively protect your health while on public transportation. Up your Vitamin C intake before departure, carry a water bottle to stay hydrated and use hand sanitizer to reduce the amount of germs to which you’re exposed from tray tables, door handles and bathroom facilities.
Also, bring your own relaxation essentials — like pillows, small blankets and eye masks — to avoid carrier-issued items that may be previously used and thus unsanitary.
2. Watch what you eat.
Skip the sugar and choose snacks of substance instead. While there are plenty of opportunities to indulge while you’re away from home, keep your diet in check (at least while you’re en route). Stuff your carry-on with healthy snacks like almonds, protein-packed granola bars, beef jerky and other munchies that travel well and will help you feel fuller longer.
3. Watch what you drink, too.
Limit alcohol consumption and defend your immune system against its dehydrating effects.
If you’re going to drink on the plane, California-licensed MD and nutrition expert Dr. Carolyn Dean recommends taking B1, B3 and B5 supplements pre-flight, and magnesium during the flight to support the alcohol dehydrogenase enzyme that breaks booze down and eliminates it from the body.
