A new study conducted by doctors at the Yale University indicates that pumping in more vitamin D into the body could cut down the impact of respiratory illness, including the irritating common cold or influenza.  

Published media reports quote researchers associated with the project to claim that those who maintain a high level of vitamin D, in the range of 38 nanograms per milliliter or more, are less likely to even contact respiratory ailments.  

Lead Researcher Dr. James R. Sabetta suggests that since vitamin D is generally acquired through exposure to sunlight, there is a higher probability that people living in sunnier climate often have higher rates of the compound in their body, thus making them less susceptible to the influenza virus. 

People living in the southern parts of the Unites States and to the west get more sun than in the north, which results in them getting more of vitamin D, Sabetta is quoted as saying by WebMD. The study was conducted across 198 healthy adults and involved monitoring their vitamin D levels for about six months.  

The research team, led by Dr. Sabetta, found that 18 members of the group maintained a high level of vitamin D with three developing flu-like symptoms during the last winter. The rest of the sample size depicted a decline in vitamin D levels with about 40 percent of this group actually falling sick.  

In their analysis paper, the team figured out that if a person had a vitamin D level of 38, the risk of allergy came down by 50 percent. However, most people who were surveyed did not have the compound at an adequate level. It is true that level 38 is just a little about what you should have to be considered in the sufficient range, Sabetta says. 

So, the next time you feel like coming down with a flu, the best bet would be to catch some sunlight. Better still, catch as much of the sun as you can, since any dip below the prescribed levels of vitamin D in the body makes you prone to influenza.
