The Connection Between Indoor Air and Flu Season
During flu season, viruses can easily circulate in enclosed spaces where fresh air exchange is limited. When a person coughs, sneezes, or even talks, respiratory droplets are released, some of which may carry viruses. Without proper ventilation, these droplets can linger in the air, creating an environment where illnesses spread more easily.
Research shows that indoor spaces with poor ventilation can see virus concentrations build up, increasing the chances of transmission. Conversely, well-ventilated spaces allow fresh air to dilute and disperse these particles, reducing the concentration of airborne viruses and, in turn, the likelihood of infection.
Why Winter Makes Ventilation So Important
Winter’s chilly temperatures encourage us to keep doors and windows tightly shut. While this keeps the heat in, it also restricts fresh air from circulating, causing indoor pollutants and germs to accumulate. Combined with the low humidity typical of winter, dry airways are more susceptible to infections. This is why improving ventilation during winter not only benefits your comfort but also supports your respiratory health.
How Improved Ventilation Reduces the Spread of Illnesses
Better ventilation has multiple health benefits beyond just reducing the concentration of airborne viruses. Here’s how it can help combat the spread of illnesses during flu season:
Dilution of Indoor Pollutants
By introducing fresh air, ventilation reduces the concentration of pollutants, viruses, and bacteria indoors. This continuous flow of fresh air disperses potentially infectious droplets more effectively.
Humidity Control
Some ventilation systems help manage humidity, which is especially important during winter when the air is drier. Proper humidity levels can keep our respiratory systems hydrated, making it harder for viruses to take hold.
Prevention of Stagnant Air
Stagnant air allows viruses and bacteria to linger longer, increasing the chance of people inhaling them. Good ventilation circulates air, preventing it from going stale and helping to clear the air of potential contaminants.
Reduction of Surface Contaminants
Ventilation doesn’t just affect the air – it can also reduce surface contaminants. Better airflow prevents germs from settling on surfaces, meaning fewer touchpoints for infection.
