According to a study, just one hour of daily exercise can help slow the progression of symptoms associated with Parkinson’s disease—symptoms that significantly impact a person’s quality of life.
Scientists suggest that activities such as playing tennis, jogging, and even gardening can delay the worsening of the disease by up to five years.
Why Exercise Matters for Parkinson’s
Millions of people worldwide live with this neurodegenerative condition. In Parkinson’s disease, nerve cells in the brain stop producing a chemical called dopamine, which leads to symptoms such as tremors and physical stiffness.
Over time, patients may lose the ability to move, speak, or swallow, and there is also a risk of a decline in their mental and cognitive faculties.

What the Study Found
Researchers at the University of Cincinnati in the United States studied 294 patients with Parkinson’s disease over a period of seven years. The average age of these patients was 66. Throughout the study, the researchers monitored changes in the patients’ physical movement as well as their mental and cognitive abilities.
The research revealed that individuals who engaged in physical activities for eight or more hours per week experienced the slowest rate of decline in their physical and mental capabilities.
These activities ranged from more strenuous forms of exercise—such as jogging and tennis—to lighter tasks, including household cleaning, using a vacuum cleaner, and gardening.
Experts believe that exercise helps protect the brain by improving blood flow, strengthening connections between nerve cells, and reducing inflammation. All these factors can prove helpful in maintaining physical and cognitive abilities.
Cognitive and Mental Benefits
According to Dr. Dong-Woo Ryu, the lead author of the study, previous research has already established a link between physical activity and symptoms related to movement. The study suggests that physical activity offers dual benefits: it is associated with both physical movement and a slower rate of decline in cognitive and mental faculties.
In this study, a standardized 30-point test was used to assess the cognitive and mental abilities of the patients. Among individuals with the lowest levels of physical activity—those who exercised for up to four hours per week—test scores showed an average annual decline of 0.48 points.
In contrast, those who exercised for four to eight hours per week experienced an annual decline of 0.009 points, while individuals who engaged in more than eight hours of physical activity per week showed virtually no decline in their cognitive and mental abilities.
Although this difference may appear minor, Dr. Ryu notes that it can have significant real-world implications, potentially allowing patients to lead independent lives for a longer period.
Physical Movement Benefits
The study, published in the medical journal Neurology, yielded similar findings regarding symptoms related to physical movement. Regular exercise is also known to support cardiovascular health; if you have concerns about heart-related symptoms, a heart attack checker tool can provide a quick, educational assessment.
Using a standardized scale to evaluate Parkinson’s-related symptoms, researchers assessed changes in patients’ gait, posture, rigidity, and overall mobility. In this regard, too, those who engaged in the highest levels of physical activity experienced the slowest progression in the severity of their symptoms.
It is also important to be aware of other serious health conditions that can present with subtle symptoms. Learning about 8 silent symptoms of stomach cancer can help you recognize warning signs early and seek timely medical advice.

For patients and caregivers, the message is encouraging: even lighter forms of movement—like gardening or housework—can contribute to a slower decline. The key is consistency and reaching a weekly activity threshold.
Further research may help refine exercise prescriptions for Parkinson’s, but current evidence already supports staying active as a vital part of managing the disease.
Why it matters: Parkinson’s affects millions worldwide. Regular physical activity—even light tasks—may delay symptom progression and help patients maintain independence for longer.
