As it is quite easy to catch a cold especially during the winter season, as a traveller you should avoid large crowds like festivals (Oktoberfest, Christmas Markets, packed public transport) or flights. Where lot’s of people come toghether, you are usually exposed to viruses and bacteria.
But as a tourist, you somehow come for such events and you often also can’t just avoid your flight to Munich.

To be honest you can’t really avoid catching a common cold. But you can try to boost your immune system. Additionally you can take some precautions to minimize the chance of getting a cold.
Here are my five tips for avoiding a cold when on route to Munich:

• Two weeks before your flight or departure to Munich, eat healthy. Lots of vegetables, less fast food and less sweets.
• Additionally get some vitamins from your local pharmacy. Also supermarkets sell immune booster products.
• Fly long-haul like a pro: Have a scarf, thick socks, an additional jacket, and long trousers with you or in your hand luggage. Trust me, no matter how hot it is in Munich or at your home destination. After four hours at 18 C /64 F you will feel chilled and at least another 4 hours are still to come. The chance to catch a cold is now very high.
• Avoid ice cold beverages three days before and three days after your journey to Munich. This one is more a legend , because cold beverages do not cause a cold. But it keeps you alerted to avoid cooling down your body more than you should.
• Wash your hands regularly. Also have hand sanitizer with you and use it regularly.
