Wearing a tie is bad, say German experts. It could be the fact that a tightened tie causes discomfort around the windpipe which may affect blood flow, or affects the jugular vein causing back pressure to the brain, thereby sending a signal that decreases blood flow to the brain.
According to a paper published last week in the journal Neuroradiology and cited by medical website Aunt Minnie, the impact of wearing neckties on people's health had largely been unknown prior to the 21st century.
For the purposes of their study, a team of researchers led by Dr. Robin Luddecke of the University Hospital Schleswig-Holstein in Kiel, Germany recruited 30 healthy young men and divided them into two groups, one group of 15 that was asked to wear open-collared shirts, and another group of 15 that was asked to wear ties.
A smooth and steady flow of blood to the brain is crucial for all our neurons and cells to continue ticking along, transmitting messages and making it possible to respond instantly to an issue, conundrum or threat. All had successive MRI scans and those in the first group were scanned wearing the tightened tie, loosening the tie but buttoning the collar, and loosening the tie and unbuttoning the collar. In the experiment involved 30 men.
The specific knot tested in this study was the popular Windsor knot, asked to be tightened to the point of slight discomfort.
Ties are something of a standard office-wear for men, from call centers to investment banks. Once the ties were loosened in these individuals, the third MRI showed that a 5.7 percent deficit in blood supply remained.
It turned out that as a result of wearing a tie cerebral blood flow is significantly reduced. The other patients also were examined, but no tie.
