Ties restrict blood flow to the brain, study finds – suggesting men who wear t-shirts in the office may produce BETTER work

Ties are something of a standard office-wear for men, from call centers to investment banks.
But a new study warns the accessory could be hampering their work performance but compressing veins that are key for bloodflow to the brain.
The small study on 30 young men in Germany found a statistically significant drop in brain functioning among men who wore neckties during an MRI scan, with bloodflow down 7.5 percent.
While that kind of decrease would not trigger obvious symptoms, experts warn it will be enough to impact cognitive functioning.
The findings are something of an endorsement for the increasingly popular tech-bro uniform championed by Mark Zuckerberg and the late Steve Jobs, doing away with ties in favor of stretchy attire.Prior to the study, published in the journal Stringer, other researchers had found evidence that a necktie increases pressure in a wearer’s eyes.
However, there was little more published about what they dubbed ‘this socially desirable strangulation’ and how it affects the brain.
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.
While Silicon Valley has been chided for its uniform of ‘ath-leisure-wear’, it fits in well with research that shows relaxation and exercise are crucial for improved bloodflow to the brain.
And this study by Robin Lüddecke at University Hospital Schleswig-Holstein is the latest evidence.
Lüddecke recruited 30 young men, 15 of whom were told to put on a tie and 15 of whom did not wear a tie.
He scanned the brains of each.
Those who put on ties were told to tie it into a Full Windsor – one more twist than a simple tie formation – and to pull it tight.
The research team saw an immediate drop in cerebral blood flow.
