Greetings,

DID YOU KNOW that one of the simplest decisions you can make for infection protection is to optimize your vitamin D levels, which is usually attained by taking supplemental vitamin D3?

Among patients hospitalized for community-acquired pneumonia, vitamin D deficiency was linked to a more than threefold increased risk for 90‑day mortality and a similar increase in risk for 180‑day mortality compared with sufficient vitamin D levels, according to Open Forum Infectious Diseases.

A study from Nutrition Reviews suggest the capacity of vitamin D to regulate inflammation, boost antimicrobial peptide activity, and positively influence cellular immune responses may help mitigate the severity of influenza infections and related complications, such as cytokine storms.

According to a study from The American Journal of Clinical Nutrition, vitamin D levels below 15 nmol/L is associated with 33% higher risk for respiratory tract infection hospitalization compared with above 75 nmol/L.

Higher vitamin D levels were associated with significantly lower length of hospital stay from COVID-19 infection, according to a study from Frontiers in Nutrition. As an added bonus, the study also found that higher omega-3 fatty acid levels were linked to much lower odds of death from COVID-19.

Finally, a study from The Journal of Nutrition found that people who consistently take vitamin D supplements are less likely to develop long COVID symptoms weeks after infection.

Steve: Respiratory infections, everything from the common cold and sinus infections to bronchitis and pneumonia, are among the most common health problems worldwide, and young children catch them especially often.

A new study from American Journal of Epidemiology followed over 2,500 people from early childhood all the way into their late twenties, tracking whether living in a damp or moldy home made them more prone to these infections. The findings were clear and consistent: people exposed to home dampness and mold had roughly 15% more upper respiratory infections (colds, sinusitis, ear infections, tonsillitis) and nearly 50% more lower respiratory infections (bronchitis, pneumonia) than those who weren't. Of all the warning signs, a moldy smell in the home turned out to be the most telling - it was linked to some of the largest jumps in infection risk, and lower respiratory infections in young adults more than doubled or tripled when mold odor was present.

Two other patterns stood out. First, current exposure mattered most: infection risk tracked closely with mold and dampness people were living in right now, though repeated water damage over the years also left a lasting mark. Second, there was a clear "more is worse" effect - each additional period of a person's life spent in a damp or moldy home nudged their infection risk higher, suggesting the harm accumulates. The damage appears to start early and follow people into adulthood, likely because mold spores, tiny particles, and airborne chemicals from damp building materials can irritate the airways and weaken the body's defenses against germs.

If you suspect you may have mold in your home, a visit from a qualified environmental testing company is a great start.
