One thing is certain: we are in the heart of cold and flu season. But have you ever wondered why we seem more susceptible to getting sick during the winter months? Research shows that spending more time indoors, dry air, and frigid temperatures could all be to blame. Let’s dive deeper into these factors and how we can minimize our chances of illness this season.
As we navigate through this cold and flu season, understanding the factors that make us more susceptible to illness can help us take steps to protect ourselves.

Germs Spread More Easily Indoors
Colder temperatures can lead us to spend more time indoors, where it’s warm. However, pathogens spread more rapidly in enclosed spaces, so when we spend more time in places like theaters, malls, restaurants, and coffee shops, our exposure to illness increases. What can we do about this? For one, don’t be afraid to go outside! Healthy children and adults can all benefit from bundling up and getting active outdoors. Just be sure to dress appropriately to protect your skin and immune system. You can also protect yourself while indoors by avoiding overcrowded buildings or wearing a face covering.
Viruses Spread More Easily in Dry Air
Cold temperatures lead to dry air, which encourages the spread of viruses. Combat this problem by running a clean humidifier in your home or office space. Humidifiers may help dampen air, which can help restrict the transmission of viruses. Keep in mind that if you have underlying health issues or allergies, be sure to discuss this with your healthcare provider first to ensure extra moisture won’t aggravate these conditions.
Cold Temperatures Can Weaken the Immune System
Studies have shown that cold air can weaken the body’s defense system, particularly in the nose, making it harder to fight off germs and stay healthy. While we can’t completely avoid going outside during winter (nor should we!), there are other ways to reduce exposure to germs. Frequent and thorough handwashing is one of the best ways to protect against illness. Also, avoid touching your eyes, nose, and mouth, including that nail biting habit. Another important step to prevent the spread of germs is disinfecting high-touch areas in your home regularly. Doorknobs, light switches, faucets, phones, and toys are just a few items that fall into this category.
As we navigate through this cold and flu season, understanding the factors that make us more susceptible to illness can help us take steps to protect ourselves. By limiting our time in crowded indoor spaces, using humidifiers, and supporting our immune system with proper hygiene practices, we can reduce our chances of getting sick this winter.
