My child is getting cold always in winter but why it is for child not for elders?

3 Doctors Answered
Any one can catch cold irrespective to age.
It is because the child had not got immunity like elders. As he grows up it will be OK.
Resistance through an airway is inversally proportional to fourth power of radius (Bernoullie's principle). Children has narrow airway which make it more susceptible for wheezing. Also the immunity at extremes of ages is less making them both children and old aged people more susceptible for infections.
