The major factor in cold and flu season

Certain diseases rear their ugly heads at certain times of the year.

This is why we have “cold and flu season.”

We have known about this for quite some time.

Yet the reason for this seasonality of the most common viral infections has been largely pushed to the side.

The obvious inference is that some weather-related factor has an influence on immunity or the ability for viruses to survive outside of the body.

Both are true…

…but the evidence shows that changing levels of vitamin D because of different levels of sun exposure…

…are the major reason for the seasonality of pandemic and epidemic viruses.

Numerous studies show that vitamin D supplementation is enough to bring immunity back up to summertime levels.

The review was carried out at Atascadero State Hospital in California. The paper was published in Epidemiology and Infection.

It was really only back in the 1980s when people began to pay serious attention to the seasonality of infectious viruses.

“In 1981, R. Edgar Hope-Simpson proposed that a ‘seasonal stimulus’ intimately associated with solar radiation explained the remarkable seasonality of epidemic influenza.”

It seems extremely important to understand what the “seasonal stimulus” for infectious viruses is.

Vitamin D is the obvious candidate. Vitamin D is increased by strong sunlight on the skin in summer when these infections are almost unknown.

“Solar radiation triggers robust seasonal vitamin D production in the skin; vitamin D deficiency is common in the winter.

Vitamin D is absolutely essential for optimal immune function.

“Activated vitamin D, a steroid hormone, has profound effects on human immunity.”

Not only does vitamin D help to protect against infection – it also decreases the inflammatory response to infection.

The inflammatory response to infection is one of the main causes of disease and death from these pathogens.

“Vitamin D acts as an immune system modulator, preventing excessive expression of inflammatory cytokines and increasing the ‘oxidative burst’ potential of macrophages.”

Vitamin D also increases the production of protective peptides – small proteins like structures which kill viral invaders.

“Perhaps most importantly, it dramatically stimulates the expression of potent antimicrobial peptides.”

These vitamin D dependent peptides are produced by the immune system, put into blood circulation and placed at the borders between the body and the outside world.

“Vitamin D related peptides exist in immune cells, and in epithelial cells lining the respiratory tract where they play a major role in protecting the lung from infection.”

Human experiments have shown that these viruses are less pathogenic in the same individual in summer than in winter.

This shows that there is an internal factor to the seasonality of viral infections.

It is not simply that there are fewer viral particles in circulation in winter.

“Volunteers inoculated with live attenuated influenza virus are more likely to develop fever and serological evidence of an immune response in the winter.”

The research also shows that people with low levels of vitamin D are much more likely to develop these types of infections.

Even children with great immune systems.

“Vitamin D deficiency predisposes children to respiratory infections.”

The rays of light which trigger the production of vitamin D in the skin decreased the likelihood of infection.

As do foods which contain large amounts of the nutrient.

“Ultraviolet radiation (either from artificial sources or from sunlight) reduces the incidence of viral respiratory infections, as does cod liver oil (which contains vitamin D).”

(Cod liver oil is probably the worst source of vitamin D because it also contains very harmful, unstable fats.)

And we have numerous studies showing that vitamin D supplementation decreases the rate of these infections.

“An interventional study showed that vitamin D reduces the incidence of respiratory infections in children.”

There can be absolutely no doubt that changing vitamin D levels are the major player in the seasonality of viral infections.

“We conclude that vitamin D, or lack of it, may be Hope-Simpson’s ‘seasonal stimulus’.”

You should always consult your healthcare practitioner for guidance on medical diagnosis and treatment.

They don’t want you to know about these virus-killing remedies…

We live in a strange time…

When someone like me can get in trouble just for telling you about natural remedies I’ve been using to beat flus and viruses.

Heck, even doctors are losing their licenses for speaking out about these remedies.

And I won’t stand for it.

So here’s what I’m doing — check it out before THEY take it down…
