NEWS BRIEF: Why your heart attack risk skyrockets in the winter

The REAL cold weather culprit and the simple solution you can start TODAY

It’s well documented that more heart attacks occur during winter than summer.

These seasonal heart attacks have been blamed on everything from the cold to shoveling snow. But a compelling new study offers even more evidence for the real cause.

The researchers discovered that older adults with inadequate vitamin D levels are over 12 times more likely to suffer from heart failure than their D-sufficient peers.1

In fact, this study of 137 men and women over the age of 60 found that people with low levels of D had an even higher risk of heart failure than those who had heart arrhythmia or were obese.

The researchers suggested that the cardiovascular benefits of D could be related to the vitamin’s ability to control chronic inflammation. This is backed up by studies in Scandinavia, Spain, and elsewhere that have linked the occurrence of heart attacks to low D levels.

So what does all of this have to do with the higher incidence of heart attacks in the winter?

Well, as I’ve reported before, just 20 minutes of full-body sun exposure during the summer can help your body make more than enough of its daily D requirements. But if you live north of Atlanta or Los Angeles, the sun isn’t high enough in the sky from October through March to produce optimum levels of D.

The result? More heart attacks in winter cold when the snow flies.

How much D do you need?

The Brazilian study defined vitamin D deficiency as less than 30 ng/ml—which contrasts with the mainstream’s 20 ng/ml threshold of deficiency.

Here is yet another study that begs the question regarding the mainstream’s low recommended levels: How do you define “sufficient” vitamin consumption when it comes to human health and disease?

Of course, the mainstream only considers bone health when it comes to the Recommended Daily Allowances (RDA) for vitamin D—completely ignoring the dosage necessary to lower the risk of cancer, heart disease, and other killers.

And not only are higher levels of vitamin D key for preventing a host of chronic diseases, they can also increase survival… In fact, in the September 4, 2017 Daily Dispatch (“Breast cancer survival rates shoot up by 63% with one simple vitamin”), I reported on the ability of vitamin D to double survival in young women with difficult-to-treat premenopausal breast cancer.

So as the light stays low and the weather remains cold, help keep your heart, body, and brain healthy by supplementing with 10,000 IU of vitamin D per day.
