Why Do We Get Sick When the Weather Changes?

Every time the temperature drops, and winter comes around everyone feels slightly worse than before, but why do we get sick when the weather changes? According to Northwestern Medicine (2022), the upper part of your respiratory system is packed with membranes that protect your body from viruses and infections but in the winter months they are welcomed with cold dry air that cause them to lose moisture. When it loses moisture, bacteria’s journey to your lungs is much easier to get you sick.

Although it may seem that the wintry weather is the reason behind getting sick, it is not. During winter, people spend more time indoors naturally due to the chilly weather. Transmission of viruses is much easier when you are in close quarters with people. Viruses also live well on surfaces inside making the transmission even easier. Seasonal allergies are also a surrounding issue due to the different pollens traveling through the air.

While you cannot guarantee that you won’t become ill, the CDC (2021) released a few ways to prevent yourself and others from getting sick. Staying home when you are sick to prevent spreading and washing your hands often to rid the viruses that live on your hands. When your hands are unwashed, avoid touching your eyes, mouth, and nose to prevent entrance of viruses.

Make sure to wash your hands and stay home in order to stay healthy this winter season!
