Overview
- Physicians caution that pressing on through an infection can lead to sinusitis, bronchitis, pneumonia, and in rare cases myocarditis.
- Red flags for medical evaluation include fever persisting beyond four days, new or worsening symptoms, facial pain, productive cough, shortness of breath, chest pain, marked fatigue, or dizziness.
- Experts advise rest, no sport during an acute infection, and delaying high‑intensity training for up to two weeks after recovery to allow the body to heal.
- Colds are caused by viruses rather than cold air, with infection typically incubating for two to seven days and spreading via droplets and contaminated surfaces.
- Preventive steps highlighted for the winter peak include distancing, thorough handwashing, gloves on public transport, adequate sleep, stress reduction, hydration, warmth, and keeping hair dry or wearing a hat in freezing conditions to avoid mucosal cooling.
