Allergy symptoms often seem to worsen or improve depending on the weather. Many allergy sufferers notice their sneezing, itchy eyes, or congestion shift with each new season or sudden weather swing. Here’s how weather changes affect allergies, which may help you prepare as conditions fluctuate:
Windy Conditions Spread Pollen
Windy days cause pollen to travel longer distances and linger in the air. For those sensitive to tree, grass, or weed pollen, gusty weather often leads to sneezing, nasal congestion, and watery eyes. Since pollen grains float more freely on a breezy day, outdoor activities may trigger symptoms more quickly. A simple step is to check local pollen forecasts and avoid outdoor exercise or gardening during windy afternoons. Closing windows and using a high-efficiency air filter at home may also keep indoor pollen levels lower.
High Humidity Leads to Mold and Dust Mites
When air moisture rises, mold spores and dust mite populations thrive. Basements, bathrooms, and kitchens become prime spots for these allergens. If you notice that your allergy symptoms worsen after a humid day or a rainstorm, indoor allergens might be the culprit. Running a dehumidifier can help keep moisture levels in check. Wiping down damp surfaces, washing bedding in hot water, and keeping bathroom ventilation fans on may also help reduce symptoms triggered by mold and dust mites.
Low Humidity Dries Out Nasal Passages
Dry weather, which often occurs in the fall or during forced-air heating, can leave your nasal passages dry and irritated. When the inside of your nose is too dry, it makes you more sensitive to airborne particles, which can cause irritation or nosebleeds. Using saline nasal sprays and keeping a humidifier running at night helps add moisture back into the air and soothes sensitive or irritated nasal passages. Drinking water throughout the day also helps keep your body hydrated, which may reduce this kind of discomfort.
Cold Weather Triggers Coughing
Cold air is harsh on the airways, especially for those who already struggle with respiratory allergies. When you breathe in chilly air, your body works harder to warm and moisten it, causing the throat and air passages to tighten. This often leads to more coughing and throat irritation.
Wearing a scarf or face covering outdoors helps warm the air before it reaches your lungs. Scheduling outdoor activities later in the day, when temperatures may have risen, provides extra comfort for those prone to cold-induced coughing. Using a humidifier indoors can also help alleviate dry air, reducing the likelihood of irritation and making it easier to manage cold-weather allergies.
Warm Weather Increases Pollution
During hot spells, pollution like ozone and smog rise to higher levels. These air pollutants often irritate the nose, throat, and lungs, exacerbating allergy symptoms. People living in urban or densely populated areas frequently notice this effect more strongly in the summer. To reduce exposure, check daily air quality reports and limit outdoor activity when pollution levels are high. Indoor exercise or outings to air-conditioned spaces help provide relief from polluted outdoor air.
Ask a Doctor About Controlling Allergies
Weather shifts affect each person differently. By paying attention to your triggers and planning your routine around the forecast, you set yourself up for more comfortable days. Simple changes, such as adjusting your routines or managing your indoor environment, may help reduce symptom flare-ups.
