Studies have shown that 20% of people who fly subsequently catch a cold a few days later. This may be due to the poor quality of the air in a plane cabin - a mixture of pressurised, thin fresh air from outside and recycled cabin air.
However, the next time you fly, try the following tips to help you minimise the risk of catching someone else's cold.
- Take an immune booster, such as echinacea and vitamin C, for a week before you fly.
- Avoid using the pillows or blankets offered by airlines; bring your own pillow instead.
- Drink plenty of water during, and after your flight.
- Avoid drinking alcohol on the flight.
- Keep your nasal passages moist by using a nasal spray.
- Wash your hands as often as you can, before, and during the flight. Use anti-bacterial soap if possible; you could also consider bringing some antibacterial hand wipes to use on the flight.
- During the flight, do not touch your face with your hands.
- If you are seated next to someone who is coughing and sneezing, ask the cabin staff (politely and tactfully) if you could possibly be moved to another seat.
