Epilogue│Old Colds, New Colds

When raising a child, there are more than one or two heartbreaking things that happen.
Usually, it's when the child is sick or injured, but after a few major events, the words 'I hope you grow up healthy' just naturally come out of my mouth.
When I see my child suffering from illnesses, including colds, from time to time, I console myself by thinking, "The child who suffered from minor illnesses when he was young is now healthy."
But this only lasts for a day or two, taking care of a sick child is really exhausting.
As I stroked the head of the child who had taken the medicine and fallen asleep, I suddenly became curious.
“Why does my child keep getting colds?”, “Why does he always get sick?”

Colds, enteritis, hand, foot and mouth disease, conjunctivitis, chickenpox, rhinitis…
If you don't get rid of the shackles of a cold, you will grow up to be a child prone to all kinds of minor illnesses!

It is the heart of every parent in the world to want to raise their precious and valuable children healthily more than anyone else.
But this yearning doesn't last as long as you might think.
A child will suffer from his or her first cold around 6 months of age, when the innate immunity received from the mother begins to decline.
As innate immunity declines and the child begins to develop his or her own adaptive immunity, all kinds of viruses can sneak in.
And once a child gets a cold, the cold never goes away, and they start going in and out of the pediatrician's office all the time.
Some days, my fever wouldn't go down easily, so I had to rush to the emergency room. Other days, my cough was so bad that I was diagnosed with pneumonia and hospitalized.


At this point, parents feel at a loss as to whether they are raising their children properly and how to raise them in the future.
However, even though their children frequently catch colds and suffer from various complications such as otitis media, bronchitis, and pneumonia due to colds, many parents do not know what a cold is.


No child is safe from a cold!
Cold Solutions You Should Never Miss for Your Child's Lifelong Health

99% of colds are caused by over 200 different types of viruses.
When secretions from the nose and mouth of a cold patient are released through sneezing or coughing, the cold viruses contained within them float in the air and cause infection when they touch the nose or hands of a healthy person.
In particular, children with weak immune systems are less able to fight off cold viruses when they enter their bodies, and thus end up catching colds.


Even if you get over a cold without any complications, it can take up to two weeks for cold symptoms such as fever, runny nose, and cough to completely disappear.
If a child catches a cold again after two weeks and then gets better, he or she will have more than 12 colds per year, or 168 days.
This is not a simple calculation number.
It means that the days of being anxious and worried because of a cold are that long.


The directors of Hamsoa Oriental Medical Clinic, who understand the feelings of such parents better than anyone else and have treated countless colds, have compiled into one book methods to raise children to be able to boost their immunity and overcome colds.
In particular, it contains cold solutions and respiratory health solutions that must not be missed for the lifelong health of children, starting from the age of 2-3, when children suffer from the most colds, and up to the age of 10, when children with sensitive respiratory systems due to frequent colds must complete treatment for various respiratory diseases including rhinitis.


Therefore, 『Colds at Three, Rhinitis at Ten』 will be the best healthy parenting book not only for parents who do not know much about colds, but also for parents of children with weak immune systems who suffer from various diseases, and parents who want to strengthen their children's immune systems through proper treatment habits from an early age.


Ham So-ah's Health Guide to Raising Cold-Resilient Children

A cold is usually cured by getting enough rest, eating well, and regulating your body temperature.
If you eat warm, easily digestible food and drink water and rest comfortably in a room with appropriate temperature and humidity, acute symptoms will subside in 2 to 4 days.
Meanwhile, the child's immune system fights off the cold virus that has invaded the body.
The inflammatory response causes fever, runny nose, and cough, but as the fight against the virus is won, the inflammation subsides and the symptoms subside.
If you catch a cold again later, you will be able to fight it off more easily based on your previous experience, and your immune system will gradually increase.

But most parents are so worried that they end up rushing to the hospital with their children in their arms.
Prescribe medications that can quickly relieve symptoms, such as cold medicine, antibiotics, and fever reducers, and give them to your child.
This hasty treatment habit blocks the child's chance to overcome the cold on his or her own.
If you repeat this process, you will eventually become unable to fight or win against any virus without the help of medicine.
A child's immune system is plagued by minor illnesses throughout his or her growth period.


It is the responsibility of parents to lay the foundation for their children to grow properly and live healthy lives throughout their lives.
How parents respond when their child catches a cold determines the child's future immunity.
If parents have a proper understanding of colds, they can reduce unnecessary medication use and raise their children to be 'children who can overcome colds well' by boosting their children's immunity.

"A Three-Year-Old's Cold, a Ten-Year-Old's Rhinitis" corrects misconceptions about colds and explains how to use cold medicines such as antibiotics and antipyretics, which can be 'medicine' when used appropriately but 'poison' when taken incorrectly, as well as proper treatment habits to boost immunity.
It provides specific treatment methods for children's illnesses experienced by parents through various actual cases.
In addition, it provides accurate information, treatment methods, and lifestyle habits for rhinitis, sinusitis, and various respiratory diseases that are similar to colds and can be easily mistaken for colds.
It will help you take care of your child's health throughout his or her life by covering all the information related to child health, including developmental characteristics, health threats, and representative diseases for each period from birth to adolescence.
