How Can Older Adults Prevent Coughs and Colds?
Older adults can reduce respiratory infection risks through handwashing and recommended vaccinations, alongside supportive habits such as sufficient sleep and good nutrition.
Although it is not possible to avoid every cold, it is possible to reduce the risk of developing one.
- Regularly wash your hands.
- Stay hydrated and eat a balanced diet.
- Get enough sleep.
- Stay up to date with the vaccinations, including influenza and pneumococcal vaccines, if advised by your doctor.
Most coughs and colds improve with rest and supportive care. However, older adults are at a higher risk of complications.
Recognizing warning signs early and seeking timely medical care can support a safer, smoother recovery.
