Over the centuries, this item of clothing has changed its shapes and names. Over time, it conquered first Europe and then the rest of the world. Swoj the present appearance of the ties took on in the early 20th century. Today, it is an integral part of formal attire, but as German scientists report in a publication, ktora appeared in the pages of the journal „Neuroradiology”, It can restrict blood flow to mozgu.
Researchers at the University Hospital Schleswig-Holstein in Germany based their study on earlier work by scientists at the New York Eye and Ear Infirmary – one of the world’s best-known otolaryngology and ophthalmology hospitals, ktoers linked the wearing of tiesow with the increase in eye pressure and possible associated risk of glaucoma.
– The purpose of this study was to further investigate the impact of how theob wearing a tie can negatively affect blood flow in the mozgu and blood flow in the carotid arteries – researchers wrote.
Using magnetic resonance imaging, the complexoł scientistsow analyzed scans of 15 men whooers wore ties tightened to the "a point of mild discomfort" and 15 men without a tie. It was found that the blood supply to mozg, drops by an average of 7.5 percent in men wearing ties, which was not observed in the control group.
Proper blood supply to the mozgu is essential for the proper functioning of. Blood provides comorkom oxygen, glucose and nutrients needed to meet energy needs mozgu. Blood is brought to the mozg through the four arteries – two cervical and two vertebral, and the ties, by putting pressure on them, cause a decrease in blood supply to the mozg.
The scientists behind the research and those whooThose who did not participate in the study stressed that 7.5 percent of the. decline should not pose a risk to healthy individualsob, but the elderly, smokers and people with high blood pressure may experience some problems because of it. They may experience bole and dizziness and nausea.
Now the teamoł wants to expand the study to include risk groups, the aforementioned smokers, the elderly and those suffering from hypertension. Researchers want to take the opportunity to returnohighlight the effects of prolonged pressure on the carotid arteries. This applies especially toolnie osob, from whichorych are required to wear a tie at work for 8 hours a day.
