Great curiosity make children love to touch various things, including what adults think is gross. Actually, as far as what the child be allowed to play dirty-dirt?
Various studies have shown, letting toddlers exposed to bacteria can actually protect them from allergic diseases and asthma in later life. The rationale is also called the “hygiene hypothesis”.
According to the hygiene hypothesis, since young children are rarely exposed to bacteria, parasites, or viruses, as adults they are more susceptible to allergies, asthma, and autoimmune diseases.
Other facts also said children who have a brother, a large farm in the neighborhood, and is in daycare (day care) early on, more rarely exposed to allergen.
Just like a baby’s brain needs stimulation, input, and interaction that perfect growth, a child’s immune system will be strong also by exposure to germs every day so that the immune army can learn, adapt, and create your own settings.
What germs they could be beneficial to the immune system of the child, it is not clear, but recent studies provide clues.
In a study conducted Thom McDade, PhD, director of the Human Biology Research Laboratory at Northwestern University, children who are exposed to animal feces and suffering from diarrhea before the age of two years, the incidence of inflammation in the body has a little more when they are adults.
Inflammation itself is associated with chronic diseases such as heart disease, diabetes, and Alzheimer’s.
“His understanding has shifted from the immune system associated with allergies and autoimmune diseases, but also an important role in inflammation and other degenerative diseases,” said McDade.
In line with McDade, according to Martin Blaser, prosefor medicine from the University of New York, most of the germs that are around or living in our bodies not only harmless but also has been with us for millions of years.
However, in line with changes in human behavior, some microbes, such as those living in the gut, to be reduced or lost. “The loss of microbes that give a result, there were good some were bad,” said Blaser.
Fear of parents are realized by keeping the child’s environment may by Blaser will eliminate their chance of exposure to naturally occurring microorganisms that are actually good for the immune system. Coupled with the use of antibiotics, which only made us weaker.
So, what should parents do? Blaser recommends that parents and doctors more prudent in giving antibiotics to children. Excessive use will weaken the child’s immune against the disease.
Maintaining cleanliness is important, but McDade suggested that parents are not obsessed with cleanliness. “Not everything needs to be washed or sterilized,” he said.
