Winter travel offers the excitement of new experiences, family gatherings, and holiday traditions. But for individuals managing allergies or asthma, seasonal changes and new environments can complicate travel plans. Cold, dry air, increased time indoors, and exposure to unfamiliar allergens can all trigger symptoms. With a bit of planning, however, it’s entirely possible to travel comfortably and safely through the colder months.
This guide will help you prepare for winter travel with practical advice on packing, air quality, and destination-specific considerations—so you can focus on enjoying your trip.
Understanding Winter Triggers
Many people associate allergies with spring pollen, but winter has its own unique set of challenges. Because cold weather keeps us indoors, exposure to indoor allergens such as pet dander, dust mites, and mold tends to increase. Forced-air heating systems circulate dust and can dry out your nasal passages, making them more sensitive to irritants.
For people with asthma, breathing in cold, dry air 
can constrict the airways, leading to coughing, wheezing, or shortness of breath. Even brief exposure to frigid outdoor temperatures—such as walking from the car to the terminal or stepping outside a hotel—can trigger symptoms. Additionally, respiratory infections are more common in winter and can exacerbate both allergies and asthma.
Understanding which triggers affect you most, whether it’s temperature, dryness, or specific allergens, helps you prepare your medications and routines accordingly before traveling.
Packing Essentials for Allergy and Asthma Management
A thoughtful packing list can make travel less stressful and ensure you’re ready for unexpected triggers.
Bring all prescribed medications in your carry-on bag, including both your rescue and controller inhalers. Keep them in their original labeled containers, as some airports and customs officials may require this. It’s also wise to bring extra medication in case of flight delays or lost luggage.
If you regularly use oral antihistamines or nasal sprays, continue to use them as prescribed. A saline nasal spray can be beneficial on flights or in dry hotel rooms, as it helps keep the nasal passages moist and reduces irritation.
Individuals with severe allergies can also benefit from carrying epinephrine auto-injectors and ensuring that their travel companions are familiar with their use. For overnight stays, allergen-proof pillow covers or a lightweight travel blanket can help you sleep more comfortably if you’re sensitive to dust mites or synthetic detergents used in hotels.
Finally, carry a written asthma or allergy action plan that outlines your usual medications, symptoms to watch for, and emergency steps. Keep a digital copy on your phone for reference.
Preparing for Your Destination
Check Air Quality and Climate
Before traveling, look up your destination’s air quality index (AQI) and weather forecast. Cold, dry, or polluted air can worsen respiratory symptoms.
In areas with poor air quality or high pollution, plan outdoor activities for early mornings when levels are typically lower. When it’s especially cold, covering your nose and mouth with a mask or scarf helps warm the air before it reaches your lungs.
Manage Indoor Environments
Indoor air can also pose significant challenges. If you’re staying in a hotel, request a smoke-free and pet-free room. Ask about heating systems—forced-air systems can circulate dust and dander—and consider bringing a small portable air purifier for your room. When staying with friends or family, be aware of pets, scented candles, and fireplaces that may irritate you.
If you suspect mold or excessive dust in a rental property, running an air purifier or keeping windows cracked (when weather allows) can improve ventilation. Using your own pillow encasement or washing bedding upon arrival can also help limit allergen exposure.
Be Aware of Altitude and Cold
If your trip involves mountain travel, remember that higher altitudes can make breathing more difficult due to lower oxygen levels. Those with asthma should give themselves time to adjust and avoid strenuous activity on the first day. For destinations with extreme cold, pre-treating with your inhaler before going outside can reduce the likelihood of airway constriction.
Air Travel Tips
Air travel can be challenging for those with allergies and asthma. Airplane cabins are pressurized and dry, which can irritate the airways. To minimize your discomfort, drink plenty of water and use a saline nasal spray during long flights. Applying a fragrance-free moisturizer around the nose can also help prevent dryness.
Keep all necessary medications in your personal item rather than checked luggage. Take a copy of your current prescriptions in case you need to refill while away. If you’re sensitive to cleaning chemicals or fragrances, use disinfectant wipes to clean your armrests, tray table, and seatbelt before settling in.
If air pressure changes trigger your asthma, talk to your healthcare provider about taking your controller or rescue medication before boarding. Lastly, inform at least one travel companion about your condition and what to do in case of an emergency—they can assist if symptoms worsen mid-flight.
Managing Symptoms During Your Trip
Take your medications on schedule, even if you feel well. Monitor environmental changes, such as sudden temperature drops or exposure to strong odors, and respond promptly if symptoms begin to develop.
In dry climates, use a humidifier in your room to help maintain moisture in the air; however, it’s important to clean it regularly to prevent mold growth. If you notice increased congestion or shortness of breath, rest and use your medications as prescribed. Avoid fireplaces, wood-burning stoves, or areas where smoke or strong fragrances linger, as these can irritate airways.
It’s also helpful to wash your hands frequently, especially during winter cold and flu season. Respiratory infections can mimic or worsen allergy and asthma symptoms. Prevention is your best line of defense.
When to Seek Medical Care
Even with good preparation, flare-ups can occur. Seek medical attention if you experience difficulty breathing, wheezing that doesn’t improve with your inhaler, or swelling of your lips, tongue, or throat. Before traveling, identify nearby urgent care centers or hospitals at your destination and keep this information accessible on your phone.
If you’re traveling internationally, consider purchasing travel health insurance that covers medical care and medication replacement. You can also keep your healthcare provider’s contact information on hand in case you need assistance managing symptoms remotely.
Winter travel doesn’t have to mean discomfort for those living with allergies or asthma. By preparing your medications, understanding environmental triggers, and planning for changes in air quality and temperature, you can travel safely and confidently.
