As the temperature drops and the leaves fall, many of us experience allergy symptoms that we usually associate with spring and summer. It’s not uncommon to hear someone say, “I have a cold,” only to find out later that it’s actually allergies. But why do we have allergies in cold weather?
Allergies are caused by the immune system’s response to allergens, which are substances that trigger an allergic reaction. In the spring and summer, pollen from trees, grasses, and weeds is a common allergen. But in the fall and winter, the culprits are usually indoor allergens like dust mites, mold, and pet dander.
So why do we experience allergies in cold weather when we’re spending more time indoors? One reason is that we’re not airing out our homes as much as we do in warmer weather. When we keep our windows closed and turn up the heat, we’re creating a cozy environment for allergens to thrive. Dust mites, for example, love warm, humid conditions, and can survive in bedding, carpets, and upholstered furniture.
Another reason is that cold weather can weaken our immune system, making us more susceptible to allergens. When we’re exposed to cold air, our blood vessels constrict, which can cause inflammation in the nasal passages. This inflammation can make it easier for allergens to enter the body and trigger an allergic response.
In addition to these factors, cold weather can also cause a condition called vasomotor rhinitis, similar to allergies but not caused by an immune system response. Vasomotor rhinitis occurs when the blood vessels in the nose react to cold air, causing a runny or stuffy nose, sneezing, and other symptoms that are often mistaken for allergies.
So what can you do to prevent allergies in cold weather? One simple step is to keep your home clean and dust-free. Vacuuming regularly, washing bedding in hot water, and using air purifiers can all help reduce indoor allergens. It’s also a good idea to keep the humidity level in your home below 50%, as this can discourage dust mites from thriving.
If you’re prone to allergies in cold weather, consider using a saline nasal spray to help flush out allergens and reduce inflammation in the nasal passages. Over-the-counter antihistamines and decongestants can also be helpful, but talk to your doctor before taking any new medications.
In conclusion, allergies in cold weather are a nuisance that can make the winter season less enjoyable. However, by understanding the causes of these allergies and taking simple steps to reduce indoor allergens, you can minimize your symptoms and enjoy the cozy season to the fullest. So, don’t let allergies dampen your winter spirit, take control of your environment, and breathe easy this winter season.
