Over time, regular chalk is rarely used. Most people have switched to using markers or chalk but free of dust. However, a study showed if the dust-free chalk is also still given bad effects on the health of children, let alone the regular chalk.
Chalk Dust Can Interfere with Breathing in Children Who Have Allergies
According to a study headed by Carlos Larramendi, chalk dust produced can endanger the health of children who have allergies to milk.
“Even chalk labeled as anti-dust was also still releasing small particles into the air. If the particles are inhaled by children who have allergies to milk, they will experience sneezing, coughing, hard to breathe. Chalk dust that is inhaled can make a child’s breathing becomes impaired, they will be a runny nose and sneeze”, said Larramendi.
Until now, ACAAI has been noted that there are approximately 300,000 children who have milk allergies in the United States. Most of them can eliminate milk allergy when they are three years old. Even so, not a few of them who still have an allergy to milk until they hit the age of 16 years.
Chalk is Not the Only Factor
Back again to the problem of chalk, chalk is not the only factor to look out for children who have a milk allergy. Some items such as glue, ink, and paper can also trigger allergies in children.
Although it’s been a lot of schools that do not use chalk, parents should also remain aware of this. Generally, there is kids who still play using chalk, especially colorful chalk. Therefore, parents are always encouraged to supervise their children who have a milk allergy or allergic to dust, to be kept away from the chalk in their everyday lives. Make sure they are not too affected by exposure to the dust from chalk.
