Comfortably dressed men may be smarter and higher-functioning than guys who wear ties — because the neckwear reduces blood flow to the brain, according to new research.
The uncomfortable office attire squeezes neck veins, potentially slowing down the brain’s processing, according to a report published last week in the journal Neuroradiology .
Scientists at the University Hospital Schleswig-Holstein in Germany scanned the brains of 30 healthy young men, according to the medical news site Auntminnie.com .
For the study, half of the men were instructed to wear comfy open-collared shirts, and the other half was told to wear Windsor-knotted ties, tightened to the point of slight discomfort, according to New Scientist Magazine .
The study found that guys wearing ties had 7.5 percent less blood flow.
In extreme cases, insufficient blood flow to the brain can kill organ tissue or cause a stroke.
