Golf courses evoke images of manicured lawns and a quiet, leisurely lifestyle.
But new research published in JAMA Network Open suggests that living near one could sharply increase your risk of developing Parkinson’s disease.
The closer you live, the worse it gets.
How does that make sense?
In the U.S., golf courses are drenched in pesticides — up to 15 times more than in most European countries.
These chemicals keep the grass green and pest-free, but they can also seep into the soil, contaminate water supplies, and possibly harm nearby residents.
Since pesticide exposure has long been linked to Parkinson’s, researchers wanted to see if the risk was higher for those living near golf courses.
They used health records from the Rochester Epidemiology Project, which includes data from residents in 27 counties across Minnesota and Wisconsin.
They studied 419 people diagnosed with Parkinson’s between 1991 and 2015, along with over 5,000 similar individuals without the disease.
Then they mapped how far participants lived from golf courses and whether they lived in areas served by water sources near or on golf courses.
Especially where groundwater was considered vulnerable to contamination.
They also accounted for age, race, gender, income, and whether someone lived in a city or rural area.
The results? Alarming.
-
● Living within 1 mile of a golf course raised the odds of Parkinson’s by 126%, compared with living more than 6 miles away.
● Each mile beyond 3 miles from a golf course reduced Parkinson’s risk by 13%.
● People using water from areas with a golf course had nearly double the odds of Parkinson’s.
● If that area had vulnerable groundwater, risk jumped by 82%.
● Those using municipal water in golf course areas had 49% higher odds than people with private wells.
But it’s not just pesticides on golf courses that cause Parkinson’s.
There are several types of chemical buildup in your brain that are causing your Parkinson’s to progress.
Which is a good thing (in a weird way) because it’s pretty easy to naturally clear out this chemical, and with that stop the progression of your condition.
