Another study by researchers from Northwestern University suggests that people with low levels of vitamin D are more susceptible to the coronavirus.
The research group analyzed hospital data for Coronavirus patients from the US, China, UK, France, Switzerland, Germany, Spain, Italy, South Korea and Iran.
The researchers found that countries with patients registering the lowest levels of vitamin D, such as Spain, France and the UK, also had the highest mortality rates from COVID-19, compared to countries with patients showing higher levels of vitamin D.
They also explained why, as they linked the vitamin D deficiency to the cytokine storm that causes a hyperinflammatory condition in the lungs.
The researchers noted:
“Cytokine storm can severely damage lungs and lead to acute respiratory distress syndrome and death in patients. This is what seems to kill a majority of COVID-19 patients, not the destruction of the lungs by the virus itself. “
The study suggested that having sufficient vitamin D may not protect you catching the virus, but it could reduce its severity and cut the chances of dying from the virus by half.
One of our biggest sources of vitamin D is sunlight that converts cholesterol into vitamin D. As a result, our vitamin D levels typically fall during the winter when there is less direct sunlight, and we spend more time inside. If this is true, would government enforced stay-at-home orders during the spring and summer actually make things worse?
It also explains why the elderly staying in rest homes are particularly vulnerable as they spend most of their time inside.
We can also get vitamin D from food and supplements, and, NOTE, vitamin D supplements are not expensive and the pills small.
