Experts from the University hospital in Schleswig-Holstein (Germany) have found that the tightening of the tie increases the risk of hypertension and poor saturation of oxygen to the brain. This publication reports Science Alert.
The study involved 30 men who underwent magnetic resonance imaging. Participants were divided into two groups, one of which volunteers are asked to wear ties and tighten to slight discomfort. The other group, control, ties are not allowed.
It turned out that the blood supply of the brain in those who wore a tie, deteriorated on average by 7.5 percent compared to the control group. At the same time, scientists do not report changes in blood flow in the jugular veins.
According to the researchers, people with normal blood pressure reduction of blood flow, most likely, will not cause health problems. However, in smokers, the elderly and patients with hypertension tightening the ties can cause additional build-up of blood pressure, aggravating hypertension, as well as headaches, dizziness and nausea, associated with insufficient oxygen supply to the brain.
