How wearing ties may raise your risk of eyesight and health issues

While many agree that ties are unnecessary and outdated, they can actually be harmful to your health.
Tie-dying can increase intraocular pressure and increase your risk of developing glaucoma or cataracts.

Hospitals are also a breeding ground for pathogens, and ties can be easily spread.

Many people accept that ties are an obligatory, but uncomfortable part of work attire.

Richard Branson and other leaders have highlighted the ubiquity of ties and suits.

Many would agree that ties are not functional. But worse, this seemingly innocuous piece of clothing can actually cause you to have a heart attack.

New Scientists investigated the effects of ties on blood flow to brain.

The study involved 15 men with ties and 15 without. Researchers found that subjects who wore ties received 7.5% less cerebral blood flow than those in the control group.

Scientists attributed lower blood flow to narrowing of carotid vessels, which transport blood away from the heart under the pressure of the tie.

Although a 7.5% decrease in blood flow might not seem significant enough to cause health problems, those who have other health issues such as high blood pressure, pensioners, or smokers should be careful. You could experience headaches, dizziness and nausea if your tie is too long.

Kiel's study on the effects of ties in the head is not a large one. According to research published by The British Journal of Ophthalmology (The British Journal of Ophthalmology), ties can also restrict blood flow to the jugular vein and carotid vessels.

This can lead to blood clots and raise eye pressure.

According to the study, elevated intraocular pressure is a risk factor in glaucoma or cataracts and could increase the likelihood of developing it.

According to Yonsei University researchers, wearing a tie can increase your risk of musculoskeletal injury. Those who wear ties report that their range of motion is "significantly reduced" when they have a tight necktie.

This causes an increase in some muscles and tension in the upper trapezius, increasing the chance of injury.

Hospital-borne diseases can be spread by ties.

Worse than straining your muscles at work, the fact that ties can be dangerous for others in health-focused settings could put them at risk. A Texas A&M Health Science Center College of Medicine study found that nearly half of the 42 male surgeons at New York Hospital had contracted infection-causing pathogens from their ties.

According to Orly Tamir and Daniel Henderson, "Hospital-acquired Infections account for a large percentage of high rates morbidity and mortality."

"We estimate that there are about 440,000 of these infections per year among adult US inpatients, and that their annual cost is $9.8 billion."

Given the fact that hospital-borne diseases are putting such a strain on healthcare systems and causing significant disruptions to healthcare, it is possible that ties containing pathogens could be contributing to an ever more serious healthcare problem.

We may have to give up on this deceptively dangerous and expensive garment and get rid of ties.
