LOOSEN UP! Neckties could reduce blood flow to brain, study says

A recent study finds wearing a necktie could reduce blood flow to the brain.

Researchers in Germany compared MRI results with a group of men wearing a necktie to those not wearing one.

They found that the ties squeezed arteries in the neck, resulting in 7 percent decreased blood flow to the brain.

Researchers say that could be dangerous for those with high blood pressure.
