Nail polish can help you feel more comfortable when you are sitting down to write, but research suggests that the chemical can actually make you more prone to a stroke.
A new study published in the American Journal of Epidemiology found that people who applied nail polish to their nails, including the ones who had a history of stroke or diabetes, were at increased risk of developing a stroke, as well as having a stroke of their own.
Researchers from the University of Wisconsin-Madison, in the US, compared the blood levels of people who had strokes with those who had never had one.
The team found that individuals who had had at least one stroke were twice as likely to have a stroke than individuals who did not.
“The more people have had a stroke and are at risk, the greater the risk that you’ll have a subsequent stroke,” Dr Jennifer A. DeGraaf, one of the study’s authors, told the BBC.
“We know that if you have a heart attack, stroke is a risk factor.
The more strokes that you have, the higher the risk.”
The researchers were also able to find that a person who had at most three strokes in their lifetime had a fourfold increased risk for a subsequent one, and a person with a history to diabetes had a threefold increase risk.
“It appears that people with diabetes are more at risk for stroke, and people with a stroke may be more at a risk of stroke,” said Dr DeGraaeaf.
Dr DeGraaaf said the study was the first to look at the impact of nail polish use on stroke risk.
“It’s important that people are aware of this risk and be aware that it can increase the severity of a person’s stroke,” she said.
“I think it’s very important that the community understand that nail paint can be a contributing factor to strokes.”
Dr Degraaf said more research was needed to understand the mechanisms by which nail polish affects the risk.
Dr Andrew E. Hager, a professor of preventive medicine at the University at Buffalo, said he was not surprised to find a link between nail polish and stroke risk because the chemical was a common household ingredient used in nail polish, even if it wasn’t approved for use by the US Food and Drug Administration (FDA).
“Nail polish is a widely used household product that has been used in many ways by millions of people around the world for decades,” Dr Hager told the ABC.
“But the FDA approved nail polish for use in certain areas of the body and approved it for the purpose of reducing pain, not preventing it.”
Nails are not very well known as a way to prevent a stroke in general.
So it’s important to get the details right.
“Dr Hager added that the FDA’s approval process for nail polish was complex and it was a “challenging” process for the company to get approval for the product.”
This research suggests nail polish might actually be a risk for an individual with a family history of a heart condition, so they should be aware of that risk,” Dr DeGraf said.
