There’s been a lot of speculation about whether or not sand has an inherent health benefit.
Now, a new study published in the journal Environmental Health Perspectives suggests that it’s the sand that could be causing the health problems.
Researchers from Columbia University, the University of Toronto, and the University at Buffalo used a large, well-controlled, randomized controlled trial to find out if sand could actually cause more health problems than conventional water and air pollution.
They looked at more than 13,000 people in the United States.
The study was designed to measure the impact of sand on the respiratory health of the participants.
The researchers wanted to know whether sand might cause health problems, but didn’t have any solid evidence to show that it did.
That’s where their new study came in.
The study showed that the average person who walks in the streets of Toronto spends nearly two hours walking on a daily basis.
That may seem like a lot, but it’s only 1.2 hours for people who live in the city center.
It also doesn’t take into account the amount of time spent outside.
But sand was a common contaminant in people’s everyday lives.
For instance, one of the largest and most polluted areas of Toronto is the east end of the city, where the city’s subway system and the city bus system converge.
People who lived in that area were also at increased risk for asthma.
To make matters worse, sand is known to have a nasty reputation for making people sick.
“Sand has a reputation as a pollutant that makes people sick,” said lead author Elizabeth E. Williams, PhD, an assistant professor of environmental science and engineering at Columbia University.
“But when we looked at the actual amount of sand we measured, we found that the amount was actually quite low, maybe 2 percent of the sand.”
Williams and her colleagues were able to estimate the health risks associated with exposure to the particles.
They were able predict that people who lived within the east side of Toronto and walked the streets were more likely to have asthma, allergies, and respiratory infections.
The researchers found that people living in the east were also more likely than those living in Toronto to have chronic respiratory diseases, such as COPD, COPD-like symptoms, and lung cancer.
Williams also said that sand has a significant effect on the human body’s immune system, and that it may even be linked to autoimmune diseases.
“Sand is a known source of allergens that may play a role in the development of chronic inflammatory diseases such as asthma, asthma exacerbations, and other chronic diseases,” Williams said.
If people in Toronto are walking on the sidewalk, the sand is in the air, but they’re not breathing in the polluted air.
That means it’s potentially contributing to a higher risk of getting asthma.
“We think that this is a potential cause for asthma,” Williams told Healthline.
“The real question is, is it really safe?”
Williams said that people with asthma should avoid walking in the street in order to avoid breathing in toxic dust particles.
And she said that if they walk on the sidewalks, they may also have more of a chance of getting a disease like COPD or COPD type symptoms, which can lead to heart disease and other complications.
Although the study looked at sand in the environment, Williams said that the study also found that walking on sidewalks in other locations was associated with increased risk of developing asthma.
“We see this in people who are older, for example, or who live near airports, where they’re often walking on crowded sidewalks,” Williams explained.
Williams and the researchers also found significant increases in the risk of asthma and COPD in people living near beaches, in particular, which has been linked to sand.
“The sand we’re talking about is coming out of the sea, and people who walk on beaches and other places that are open, especially in summer, may have an increased risk,” Williams added.
As for why sand was associated to increased risk, Williams and her team believe that sand’s ability to form a thick film in the lungs could help with the transmission of pollution.
In the long run, Williams says, the health benefits of walking in sand will depend on the size and composition of the particles and the way they are transported in the body.
“There are some chemicals that can help, and some of those chemicals are quite volatile, so people with chronic asthma can have a higher exposure,” Williams pointed out.
“And also in the long term, there’s an increased number of people that live in urban areas and that is a major factor in asthma.”
There are still a lot more questions about how sand is affecting people’s health.
Health experts said that a lot remains to be seen in order for the sand to become a major public health concern in Toronto.
There’s currently no known reason why sand should be considered a public health threat.
