As temperatures drop, illnesses like the flu, colds, and respiratory infections spike. While anyone can catch a winter illness, certain populations are at higher risk of getting sick and experiencing complications. Understanding these vulnerabilities can help you and your loved ones take proactive steps toward staying healthy this season.
So, who is more vulnerable to winter illnesses, and how can you protect those around you?
Why Winter Increases the Risk of Illness
Before diving into specific populations, let’s understand why winter heightens the risk of getting sick:
- Cold Weather: The drop in temperature can weaken immune defenses and make respiratory viruses more stable and infectious.
- Indoor Crowding: More time spent indoors leads to closer contact, making it easier for viruses to spread.
- Dry Air: Dry winter air dries out the mucous membranes in the nose and throat, reducing your body’s ability to trap and fight off germs.
7 Groups of People More Likely to Get Sick in the Winter
1. Infants and Young Children
Why They’re at Risk:
Young children, especially those under 5 years old, have developing immune systems, making it harder for their bodies to fight off infections. Babies and toddlers are also more likely to touch surfaces and put their hands in their mouths, increasing exposure to viruses and bacteria.
Common Illnesses:
- Respiratory Syncytial Virus (RSV)
- Influenza (flu)
- Colds
- Pneumonia
- Bronchiolitis
Prevention Tips:
- Keep up with vaccinations, including flu shots and childhood immunizations.
- Encourage frequent handwashing.
- Avoid crowded places during peak cold and flu seasons.
- Limit exposure to sick individuals.
2. Older Adults (65 and Over)
Why They’re at Risk:
As we age, our immune systems weaken, making it harder to fight off infections. Older adults are also more likely to have chronic health conditions, such as diabetes, heart disease, or COPD, which can worsen illness outcomes.
Common Illnesses:
- Influenza (flu)
- Pneumonia
- COVID-19
- Shingles
Prevention Tips:
- Get annual flu shots and pneumococcal vaccines.
- Practice good hygiene and avoid large crowds.
- See a healthcare provider promptly if you experience symptoms of a respiratory illness.
- Maintain a healthy lifestyle with balanced nutrition, exercise, and adequate rest.
3. People with Chronic Illnesses
Why They’re at Risk:
Chronic conditions like diabetes, heart disease, asthma, and autoimmune disorders can weaken the immune system, making it harder to recover from infections. Certain illnesses, like asthma or COPD, may also flare up in cold weather.
Common Illnesses:
- Flu and colds
- Pneumonia
- Bronchitis
- COVID-19
Prevention Tips:
- Manage chronic conditions with the help of a healthcare provider.
- Stay current with vaccines, including flu and COVID-19 shots.
- Avoid smoking and exposure to secondhand smoke.
- Stay active and eat a balanced diet to support overall health.
4. Pregnant Individuals
Why They’re at Risk:
Pregnancy naturally suppresses the immune system to support the developing baby. This makes pregnant individuals more susceptible to infections and more likely to experience complications from illnesses like the flu.
Common Illnesses:
- Influenza (flu)
- COVID-19
- Colds
Prevention Tips:
- Get recommended vaccines, including the flu shot and Tdap vaccine.
- Practice good hand hygiene and avoid close contact with sick individuals.
- Stay hydrated, eat a balanced diet, and get adequate rest.
5. People with Weakened Immune Systems
Why They’re at Risk:
Individuals with weakened immune systems—such as those undergoing chemotherapy, taking immunosuppressive medications, or living with HIV/AIDS—have a reduced ability to fight off infections.
Common Illnesses:
- Flu and colds
- Pneumonia
- Fungal infections
Prevention Tips:
- Stay up-to-date with all vaccines.
- Avoid large gatherings during flu season.
- Follow medical guidelines for managing your immune condition.
- Wash hands frequently and disinfect high-touch surfaces.
6. Healthcare Workers and Caregivers
Why They’re at Risk:
Those who work in healthcare settings or care for others are regularly exposed to illnesses. Constant contact with patients or family members who are sick increases the risk of infection.
Common Illnesses:
- Influenza (flu)
- COVID-19
- Common colds
- RSV
Prevention Tips:
- Get vaccinated, including flu shots and COVID-19 boosters.
- Follow infection control measures like wearing masks and gloves.
- Practice regular handwashing and disinfecting surfaces.
- Monitor your health closely and take sick days if you have symptoms.
7. People Experiencing Homelessness
Why They’re at Risk:
Lack of access to adequate shelter, nutrition, and healthcare increases vulnerability to winter illnesses. Exposure to cold, damp environments and crowded shelters heightens the risk of infections.
Common Illnesses:
- Pneumonia
- Influenza (flu)
- Respiratory infections
- Tuberculosis
Prevention Tips:
- Community efforts to provide shelter and healthcare services.
- Access to vaccines and basic hygiene resources.
- Warm clothing and blankets during cold weather.
How to Stay Healthy During the Winter
No matter your risk level, there are steps everyone can take to stay healthy during the winter months:
Get Vaccinated
Flu shots, COVID-19 boosters, and pneumococcal vaccines offer critical protection.
Practice Good Hygiene
Wash hands regularly, cover coughs and sneezes, and disinfect high-touch areas.
Stay Active and Eat Well
Support your immune system with regular exercise, balanced nutrition, and hydration.
Dress Appropriately
Wear layers and protect yourself from the cold.
