Schleswig-Holstein, Germany (4E) – If you want to be more creative at work and be more productive, lose the necktie.
A new study shows that formal man’s favorite accessory, the cravat, limits oxygen supply to the brain of its wearer. The result: a reduction in blood flow to the brain by 7.5 percent. The new study was published in the journa,l Neuroradiology.
Why? That’s because wearing a tie squeezes the neck veins. This constriction limits blood flow and can slow down the processing of the brain, thereby limiting a person’s thinking skills and creativity.
Thirty men were recruited men for the study, half of whom were asked to wear ties, said researcher Robin Lüddecke from University Hospital Schleswig-Holstein in Germany.
After scanning the brains of the participants, researchers found the ties squeezed the veins where blood passes to reach the brain, cutting off circulation by 7.5 percent. The percentage is sizable enough to make a fatal difference for those with high blood pressure.
“The examination resulted in a statistically significant decrease of cerebral blood flow (CBF) after tightening the necktie (p < 0.001) while the venous flow did not show any significant changes,” wrote the researchers in their study. “It appears that wearing a necktie leads to a reduction in CBF.”
This isn’t the first time a potential health hazard is associated with wearing neckties. An earlier study showed that wearing a tie too tight might increase a person’s risk of blindness. It found wearing a tie boosts intraocular pressure (the fluid pressure inside the eye), which is associated with glaucoma.
Glaucoma is one of the top causes of irreversible blindness. It occurs when increases in pressure cause damage to the eye. Experts said that neckties probably cause the problem because wearing them constricts the jugular vein, the main blood vessels that return blood from the head toward the heart.
