Wearing ties hamper productivity in office; here's why

Ученые Галстуки представляют смертельную опасность для мужчин

Interestingly, the researchers did not notice any statistically significant changes when it came to blood flow in the jugular vein.

30 men were recruited, 15 wearing a neck tie and 15 with an open collar shirt. Experts said that ties possibly cause the problem because wearing them constricts the jugular vein, the main blood vessels that returns blood from the head towards the heart. Cerebral blood flow figures were similar across all three scans for those in the control group.

The two groups were given a set of three MRI scans, with the men in the open-collared shirt group going through the last two MRI scans without a tie.

Results of the brain scans or MRIs showed that those who wore the ties had a 7.5 percent less blood flow to their brains.

The team of scientists included 30 healthy male participants (average age around 24 years) in their study and scanned their brains. Once the ties were loosened in these individuals, the third MRI showed that a 5.7 percent deficit in blood supply remained.

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.

Lack of adequate blood supply to vital areas of the brain can cause damage to the areas of the brain and also reduce the functional capacity of the brain as has been seen from earlier studies.

In 2003 a study suggested intraocular pressure could rise with the wearing of tight ties, worsening glaucoma, a leading cause of blindness.

"If the patient consistently were to wear a tight necktie as a normal preference in daily life, this could lead to a sustained increase in IOP and could predispose to the development of glaucomatous optic neuropathy, thereby rendering a tight necktie a risk factor as well as a confounder of accurate IOP measurement", the researchers wrote in their study.
