Do You Know That Ties Are Able to Reduce Blood Supply to the Brain?

Recent study from Germany shows that ties can reduce blood supply to the brain, making an ultimate excuse for men to dress more casually at work.

According to study, if you feel slightly uncomfortable after wearing a tie, your brain blood flow will reduce by 7.5% without any following physical symptoms. However, when the amount gets 10%, your body will start to react.

How is this research conducted?

Past studies show compression of the neck veins into your neck part reduces blood flow to the brain. Researchers in this new study published in the Neuroradiology tested whether the pressure on the tie could make such a change. They recruited 30 young men between the ages of 21 and 28, dividing them into two groups: worn and not worn.

The researchers used MRI to detect cerebral blood flow, total blood flow to the brain, as well as the blood flow to the neck vein. The first MRI was a baseline scan where both subjects were open neckline or wearing a loose tie. On the second scan, the men’s neckline was fastened and the tie group was worn to buckle the tie to Windsor to the extent that they felt slightly uncomfortable. The third scan was the same as the baseline scan. All scans lasted 15 minutes.

What did they find?

The authors found that wearing a tie that was slightly uncomfortable with a Windsor knot for 15 minutes resulted in a 7.5% decrease in cerebral blood flow and a 5.7% decrease in blood flow 15 minutes after the tie was released. No changes in blood flow to the venous vessels of the neck were found in either group.

What does this mean?

The study did not delve into any details about this impact, so let’s consider what might be affected. The 7.5% reduction in blood flow found by researchers is unlikely to cause problems for most men. Healthy people usually begin to develop symptoms when their blood flow is reduced by 10% – a figure larger than that found in this study. A 10% reduction in blood flow can cause an increase in local blood pressure, which can lead to dizziness, headache, and nausea.

However, even if the blood flow in the brain only drops by 7.5%, some temporary dizziness, headache or nausea may occur.

Combined with some other factors, such as smoking or aging, a 7.5% drop in blood flow can cause some people to feel more than the threshold of 10%, giving them more stress on the already tight body, increasing their loss of consciousness or developing high blood pressure.

What else do we need to consider?

Scientists also need to do more research to assess the impact of wearing a tie for a long time and different knots. Any pressure on the neck is slightly uncomfortable, and the men’s dress code suggests a tie that is “tight but not too tight.”
