why do i always get sick after traveling

Traveling is a wonderful experience that allows us to explore the world, create lasting memories, and take a break from our daily routine. However, for some people, traveling can also mean getting sick. Nothing can ruin a trip quite like falling ill, especially if it happens frequently. In this article, I will delve into the reasons why some individuals seem to always get sick after traveling, and offer some tips on how to stay healthy while on the go.

1. Change in Climate and Environment

One of the most common reasons for falling ill after traveling is the dramatic change in climate and environment. Our bodies are accustomed to a certain temperature, humidity, and allergens in our local environment. When we travel to a different destination, especially one with extreme temperatures or unfamiliar allergens, our immune system may struggle to adapt, making us more susceptible to illness.

1.1 Tip:

Research the climate and common allergens of your travel destination in advance, and pack appropriate clothing and medications to minimize the impact of the change in environment on your health.

2. Stress and Fatigue

Traveling can be stressful, especially when dealing with flight delays, lost luggage, or navigating unfamiliar places. The stress of travel can weaken our immune system, making it easier for bacteria and viruses to take hold. In addition, the physical and mental fatigue from long flights and jet lag can further compromise our body’s ability to fight off illness.

Plan your travel itinerary to allow for rest and relaxation, and practice stress-reducing techniques such as deep breathing or meditation. Stay hydrated and prioritize sleep to combat travel fatigue.

3. Exposure to New Germs

When we travel, we come into contact with a myriad of new germs and viruses that our bodies may not have encountered before. Airports, public transportation, and crowded tourist attractions are breeding grounds for pathogens, increasing the risk of getting sick.

3.1 Tip:

Practice good hygiene by washing your hands frequently, using hand sanitizer, and avoiding touching your face to reduce the risk of coming into contact with new germs. Consider wearing a mask in crowded areas to protect yourself from airborne pathogens.

4. Dietary Changes

Trying new foods is an exciting part of travel, but it can also lead to stomach upset and foodborne illnesses. Our digestive system may not be accustomed to the spices, ingredients, or food preparation practices of a different culture, leading to gastrointestinal issues.

4.1 Tip:

Be mindful of what you eat and drink while traveling. Avoid consuming uncooked or undercooked foods, and opt for bottled water to reduce the risk of food poisoning. Consider bringing probiotics to support your digestive health during travel.

5. Lack of Exercise

Travel often involves long periods of sitting, whether on a plane, train, or bus. This sedentary lifestyle can weaken our immune system and lead to aches, pains, and even blood clots. Lack of physical activity can also contribute to feelings of lethargy and fatigue, making us more susceptible to illness.

5.1 Tip:

Stay active while traveling by taking short walks, stretching, or doing simple exercises in your hotel room. Consider incorporating physical activities into your travel plans, such as hiking, cycling, or swimming, to maintain your fitness level.


While getting sick after traveling can be frustrating, it is important to remember that our bodies undergo a lot of stress and changes during the travel process. By being mindful of the potential health risks associated with traveling and taking proactive steps to mitigate them, we can increase our chances of staying healthy and enjoying our adventures to the fullest.

1. How can I boost my immune system before traveling?

Prior to your trip, focus on maintaining a healthy lifestyle by eating a balanced diet, getting regular exercise, and ensuring an adequate amount of sleep. Consider taking immune-boosting supplements such as vitamin C, zinc, and probiotics to support your body’s defenses.

2. What can I do to minimize the impact of jet lag?

To ease the symptoms of jet lag, gradually adjust your sleep schedule to match the time zone of your destination before departing. Stay hydrated, avoid alcohol and caffeine, and expose yourself to natural sunlight upon arrival to help reset your body clock.

3. Is it safe to drink tap water in foreign countries?

While tap water safety varies by country, it is generally advisable to drink bottled or filtered water when traveling to a foreign destination to avoid the risk of waterborne illnesses. Use bottled water for drinking, brushing your teeth, and washing fruits and vegetables.

4. How can I prevent motion sickness while traveling?

To alleviate symptoms of motion sickness, avoid reading or using electronic devices during transit, sit near the front of a vehicle or over the wing of an airplane, and focus on a fixed point in the distance. Over-the-counter medications such as meclizine or dimenhydrinate can also be effective for preventing motion sickness.

5. Should I get travel insurance to cover medical expenses abroad?

It is highly recommended to purchase travel insurance that includes coverage for medical emergencies and evacuation while traveling abroad. This can provide peace of mind and financial protection in the event of unexpected illness or injury during your trip.
