How to reduce your cold risk as autumn begins

As autumn begins, the risk of colds rises due to increased indoor gatherings and travel after summer. Experts recommend handwashing, ventilation, and distancing to reduce infection risk. Key protective measures include regular thorough handwashing, frequent room ventilation, and maintaining distance from people who cough or sneeze. Those with symptoms should stay home for 3-5 days, and at-risk individuals should consult a doctor. No vaccination exists for common cold viruses, but shots can protect against flu, COVID-19, and RSV. A healthy lifestyle helps, while vitamin C and echinacea show limited effect, though probiotics may reduce colds.
