Is Your House WRECKING Your Brain? (Here’s How to Tell)

It starts with little things… like forgetting where you left the car keys.

Maybe you can’t remember why you walked into a room… or your grandkids joke that you’re repeating the same stories.

Too many doctors dismiss memory issues or cognitive decline as a “normal” part of aging… but there’s way more to the story.

Because the biggest threat to your brain may not be Father Time… it may be your own house.

New research is showing that a common problem occurring in millions of American households may send your risk of brain problems through the roof.

And the simple steps you take today could go a long way toward keeping your brain safe as you age.

A new study out of China looked at nearly 12,000 adults with an average age of 82 – so prime age for memory problems.

And what they found was remarkable…

People who reported musty odors in their homes – which indicates mold — were a whopping 40% more likely to be  suffering from cognitive impairment.

Mold seemed to make the difference between which seniors had brains that aged well… and which didn’t.

And, honestly, that’s not too surprising. We know that mold is toxic to brain cells and can also trigger inflammation that is unhealthy for your brain.

Mold exposure can also interfere with your sleep, which has an enormous effect on brain performance.

And if you don’t think your house has mold, well, you might be surprised. Research has shown that nearly half of American homes have some level of mold.

The problem is that too many homeowners just learn to live with it – and that can have serious consequences for your overall health, including your brain.

You can find some home mold test kits online for about $20. But it’s often a smart idea to hire a Building Biology Environmental Consultant.

These trained professionals can look for mold and other indoor toxins – such as electromagnetic fields – that could be undermining your health.
