Baby's Immune System
5 Ways to Give Baby's and Toddler's Immune System a Boost
By Donna Smith
Smoking affects not only the user's health, but the health of everyone around him or her – especially babies and toddlers.
"Secondhand smoke has bad effects on the immune systems of infants, especially the immune system in the lungs," Dr. Cole says. "Secondhand smoke contains substances that interfere with normal immune development in the lungs. For example, children exposed to secondhand smoke have more serious lung infections and are more likely to develop asthma. Secondhand smoke also reduces the amount of vitamin C in a child's system, and this deficit may also contribute to immune problems."
Dr. Renna agrees. "Secondhand smoke destroys the lining of the respiratory tract," she says. "This lining is one of the first defenses when we breathe in germs, and if the system is compromised it can't protect us as well."
Have you been smoking around your child? It's never too late to stop. "Once the exposure to smoke has ceased the cells and the hair-like projections called cilia (these cilia push debris and germs that we breathe in out of the respiratory tract) grow back and start to protect again," Dr. Renna says.
"Stopping smoking is one of the best things a parent can do for her/his baby – quitting smoking not only improves a baby's immune system but also ensures that the baby will have a healthy parent," Dr. Cole says.
