It was recently shown in a study which took place in Costa Rica, that having a deficiency in your vitamin D levels may actually make your asthma much worse. The study involved over 600 children all of which suffered from asthma. The researchers did various tests on the kids finding the relative severity of their asthma, how often they had to treat themselves, how often they needed to go to hospital with their conditions and what their levels of vitamin D were. It was found that those who had higher levels of vitamin D were hospitalized much less, had a generally less severe form of asthma and had to treat themselves much less often.
It’s now being suggested that if children who’ve shown deficiencies in their vitamin D levels were to take supplements then they could lessen the severity of their asthma. As you probably know, asthma is potentially fatal so anything which can lessen that danger is a fantastic advancement and with the treatment being a supplement it’s about as simple as it can be and cheap to boot!
This study was the first of its kind and as such further research will need to be done before anything overbearingly definitive is set it stone. However, nothings stopping you from having your child’s vitamin D levels tested and giving them a supplement if you find them lower than usual!
