How Neckties Reduce Blood Flow to Your Brain

Neckties have long been a staple of men’s fashion, adding a touch of sophistication to formal attire. However, recent research suggests that these stylish accessories may have unintended consequences for our brain health. Studies have shown that wearing a necktie can lead to reduced blood flow to the brain, potentially affecting cognitive function. In this article, we delve into the science behind this phenomenon, exploring the research findings, potential health risks, and alternative options for those seeking a balance between style and brain health.

The Impact of Neckties on Blood Flow

A study published in the journal Neuroradiology shed light on the connection between neckties and cerebral blood flow. Researchers from the University Hospital Schleswig-Holstein in Germany conducted brain scans on 15 healthy young men before and after they wore neckties. The participants were instructed to tie their neckties tightly, causing slight discomfort.

The results were surprising. Immediately after tightening their ties, the participants experienced a significant drop in blood flow to their brains. This reduction in cerebral blood flow persisted even after the ties were loosened, suggesting that the constriction caused by neckties could have long-lasting effects on brain function.

Understanding Cerebral Blood Flow

Before we delve further into the impact of neckties on blood flow, let’s briefly discuss cerebral blood flow and its importance. Cerebral blood flow refers to the amount of blood that circulates through the brain, delivering oxygen and nutrients while removing waste products. Optimal cerebral blood flow is crucial for maintaining brain health and supporting cognitive processes.

When blood flow to the brain is compromised, it can lead to a range of issues, including decreased cognitive function, impaired concentration, and even an increased risk of stroke. Therefore, any factors that contribute to reduced blood flow in the brain should be carefully considered.

The Mechanism Behind the Reduction in Blood Flow

The researchers hypothesize that the tightness of neckties contributes to the reduction in blood flow to the brain. Neckties, when tied tightly, can constrict the arteries and veins in the neck, impeding the smooth flow of blood to and from the brain. This constriction creates a bottleneck effect, hindering the delivery of oxygen and nutrients to the brain while impeding the removal of waste materials.

The Findings: A Closer Look

Upon analyzing the MRI scans of the participants, the researchers observed a 7.5% decrease in cerebral blood flow when the ties were tightened. Even after the ties were loosened, a 5.7% deficit in blood supply remained. Notably, five out of the 15 participants experienced a decrease in cerebral blood flow greater than 10%.

While this study provides valuable insights into the impact of neckties on blood flow to the brain, it is important to acknowledge its limitations. The sample size was relatively small, consisting of only 15 participants. Additionally, the study did not consider factors such as neck size or the participants’ regular necktie-wearing habits.

Potential Health Risks

The decrease in cerebral blood flow caused by neckties raises concerns about potential health risks. Although the exact implications of reduced blood flow to the brain are not yet fully understood, there are several areas of health that may be affected:

  1. Cognitive Function: Decreased blood flow to the brain can impair cognitive function, leading to difficulties in memory, concentration, and overall mental performance. Long-term exposure to reduced blood flow may have cumulative effects on brain health.
  2. Stroke Risk: While the study did not directly investigate the risk of stroke, it is well-established that compromised blood flow to the brain can increase the likelihood of strokes. Individuals with pre-existing health conditions such as high blood pressure, heart disease, or diabetes may be particularly vulnerable.
  3. Eye Health: Neckties that are tied tightly can also impact blood flow to the eyes. Studies have shown that wearing a tight necktie can increase intraocular pressure, which may be a risk factor for eye conditions such as glaucoma.
  4. Microorganism Accumulation: Neckties, being in close proximity to the face, can accumulate bacteria, food particles, and other contaminants. This can potentially lead to skin irritation, respiratory issues, or even the spread of infectious diseases.

Alternatives to Traditional Neckties

Given the potential health risks associated with neckties, individuals may opt for alternative options that strike a balance between style and brain health. Here are a few alternatives worth considering:

  1. Bowties: Bowties are a classic and stylish alternative to traditional neckties. They add a touch of sophistication without constricting the neck or impeding blood flow.
  2. Open-Collar Shirts: Opting for open-collar shirts can provide a more relaxed and comfortable look while still maintaining a professional appearance. This allows for unrestricted blood flow to the brain.
  3. Clip-On Ties: Clip-on ties offer the convenience of a necktie without the need for tying a knot. They eliminate the risk of strangulation or accidents associated with traditional neckties.
  4. Necktie-free Dress Codes: In certain industries or workplaces, adopting a necktie-free dress code may be a viable option. Many modern companies, particularly in the tech industry, have embraced a more casual approach to workplace attire.


While neckties have long been a symbol of professionalism and style, the research suggests that they may come at a cost to brain health. The constriction caused by neckties can lead to a reduction in blood flow to the brain, potentially affecting cognitive function and increasing the risk of certain health issues. Individuals concerned about these potential risks can explore alternative options that prioritize both style and brain health. By making informed choices, we can maintain our professional appearance while safeguarding our well-being. So, next time you reach for a necktie, consider the impact it may have on your brain and explore alternatives that allow you to express your style without compromising your health.
