A Tight Necklace May Reduce Brain Blood Flow by 7.5%

Wearing a necktie, especially when tied too tightly, can unexpectedly have an effect on blood circulation, which eventually reduces blood flow to the brain by up to 7.5%. This phenomenon occurs because a tight necktie can compress the jugular veins and other blood vessels in our neck. When these vessels are constricted, blood flow from the brain back to the heart is restricted, which in turn can cause a reduction in the amount of oxygenated blood which circulates to the brain.

Many researches suggests that the pressure exerted by a tight necktie can cause discomfort and even lead to a sensation of dizziness or lightheadedness. This constriction affects venous return, which is the process by which deoxygenated blood returns to the heart. This slows the overall circulatory system, and in turn, reduces the brain's access to the oxygen that it needs to function properly.

While the impact may seem very little, long-term wearing of tight neckties may contribute to subtle cognitive effects, such as decreased of concentration or fatigue. This has led to discussions about the potential health risks associated with wearing neckties for extended periods, especially in formal or office settings. Adjusting the tightness of the necktie, or even opting for a looser, more comfortable style, can help you to maintain proper blood flow and prevent the negative effects on brain function.
