Why do I keep getting colds in winter?

Recurrent winter colds are usually linked to increased viral exposure, indoor crowding, and seasonal immune changes. In this episode, we explain why colds are more frequent in colder months and how risk is assessed in Europe.

In this episode, we cover:

• What the common cold is (a viral upper respiratory tract infection)

• Why viruses spread more easily in winter

• The role of indoor heating and low humidity

• Reduced sunlight and vitamin D considerations

• Sleep, stress, and immune function

• When recurrent infections may suggest an underlying condition

• Differences between colds, flu, and sinus infections

• When antibiotics are not appropriate

• Red flag symptoms requiring medical review

Doctors assess frequency of infections, duration, fever pattern, underlying conditions (asthma, diabetes), smoking status, medication use, and immune risk factors before advising treatment. Persistent high fever, shortness of breath, chest pain, or symptoms lasting beyond typical duration require in-person evaluation.

This episode reflects how seasonal respiratory infections are reviewed within structured medical assessment in European telemedicine at Mobi Doctor.
