The devastating side effect of those “harmless” seasonal allergies

Plus, my step-by-step plan to a lasting solution

I don’t need to tell you how rough allergy season can be on your sinuses. Any longtime sufferer knows the struggle. But what you may not be as aware of is how hard it is on your brain, too.

In fact, previous studies have already demonstrated that sinusitis can impact thinking, focus, and sleep. And now, new research has strengthened the link between sinus inflammation and changes in brain activity.

And with months of seasonal allergy struggles still ahead of us, I couldn’t think of a better time to share the news—along with my step-by-step plan for a permanent solution.

The inflammatory origins of brain fog

Scientists used data from more than 1,200 adults between the ages of 22 and 35 years, which included both brain imaging and cognitive/behavioral assessments.

The researchers identified 22 people with moderate or severe sinus inflammation. Then, they compared them to 22 subjects without any sinus inflammation. And MRIs revealed some pretty major differences, including:

  • Lower connectivity in executive function, attention, and problem-solving hubs
  • Higher connectivity in areas of the brain activated during wakeful rest and mind wandering
  • Lower connectivity in areas involved in processing external stimuli, communication, and social behavior

Plus, the extent of these differences in brain activity directly correlated with the degree of sinus inflammation each subject suffered.1 And that finding makes a lot of sense.

But one thing that was surprising was that these brain changes appeared to have no bearing on the subjects’ behavioral and cognitive functioning. (That said, this study looked at a young population.)

At a minimum, these findings offer a pretty clear-cut explanation for any unusual brain fog that allergy season ushers in. And it’s more than plausible that all that’s needed to escalate these neurobiological changes into full-blown cognitive decline is time and lack of treatment.

Simple steps towards permanent relief

Obviously, as research like this shows, allergies aren’t just a nuisance… they can be downright dangerous. But the good news is, I found a way to naturally eliminate my own allergies—and I’ve been helping my patients do the same for decades.

That means nearly every miserable symptom—the annoying coughs, constant sneezing, uncomfortable congestion, irritated eyes, brain fog—can greatly improve without relying on a single drug.

Because the truth is, if you take the time to repair your body, you will reap the rewards.

That’s why I’ve spent the last several months pulling together an interactive, comprehensive protocol—including 20 years’ worth of extensive research and personal experience—to help you banish those pesky allergies… naturally and for good.

SIDEBAR: Key differences between allergies and COVID-19

I’ve already outlined some of the most common allergy symptoms—but some of these overlap with the notorious coronavirus… and even the common cold!

So, here are three key indicators that could point you more definitively to COVID-192:

1.) Loss of taste and smell. Generally, we don’t see these symptoms with other viruses. Yes, a cold (and even allergies) can blunt your sense of taste and smell, especially if your nose is stuffed up. But so far, healthcare workers on the front line are seeing more rapid and dramatic losses of taste and smell with COVID-19.

2.) Chest pressure or pain, or severe headaches. COVID-19 has a unique impact on the blood vessels and can cause blood clots. So in addition to the more common symptoms listed above, you might also feel symptoms like chest pressure or pain, or a severe headache.

3.) Fever and chills. Simply put, allergies don’t cause a fever and chills—whereas these are two common symptoms of COVID-19.
