The reason why you're more likely to get sick when it's cold and rainy

NEW ORLEANS, Dec. 4 - As the weather turns colder and the rain settles in, many people start to notice sniffles, sore throats, and a general feeling of being run down. It might seem like the weather itself is making you sick, but the real reasons are a mix of science, environment, and the way our routines shift during the winter months.

At BCHS, we want our community to understand what is really going on this time of year so you can keep yourself and your family healthy.

Cold weather does not cause illness, but it does make it easier to get sick

Viruses like the flu and common cold spread more easily in winter because they survive longer in cold, dry air. When the temperatures drop, the protective lining in our nose becomes less effective, which makes it easier for viruses to enter our body.

People spend more time indoors

Cold and rainy days push everyone inside. Classrooms, workplaces, stores, and homes become crowded spaces. When people are close together, viruses spread more quickly. One cough or sneeze in a closed room can reach others faster than it would outdoors.

Immune systems can slow down in winter

Less sunlight means less natural vitamin D, which plays a role in immune function. Dark, rainy weeks can also affect sleep patterns and energy levels. When the body is tired or stressed, it becomes easier for illness to take hold.

More holiday gatherings mean more germs moving around

From family dinners to classroom parties, the winter season brings many opportunities for viruses to spread. Sharing food, hugging loved ones, and spending time in warm indoor spaces all increase the likelihood of exposure.

How to stay healthy during cold and rainy weeks

A few simple steps can go a long way.

• Wash your hands often. This is one of the most effective ways to prevent illness.
• Stay hydrated. Water helps your immune system work at its best.
• Keep your home clean. Wipe down surfaces that are touched often.
• Get enough sleep. Tired bodies are more likely to get sick.
• Spend time outdoors when you can. Even a few minutes of sunlight can support your mood and immune health.
• Get your vaccinations. Flu vaccinations can greatly reduce your risk of serious illness.
