A cardiology consultant has revealed that excessive exercise may increase the risk of stroke in rare cases, mostly among individuals with underlying health conditions.

Dr. Harnish Singh Batia, Interventional Cardiologist at Fortis Hospital in Greater Noida, India, said that “regular exercise remains one of the most effective ways to reduce the risk of heart disease and stroke.”
However, he emphasized that “extreme or prolonged physical exertion may temporarily increase the risk of stroke in some individuals with pre-existing medical conditions,” according to NDTV.
When is the risk higher?
During high-intensity exercise, heart rate and blood pressure rise significantly. Although this is generally safe for healthy individuals, it may pose a risk for those with uncontrolled high blood pressure, heart rhythm disorders, diabetes, or vascular diseases.
Experts warn that certain groups should exercise caution before engaging in strenuous training programs, including individuals with uncontrolled hypertension, atrial fibrillation (irregular heartbeat), diabetes, long-term smokers, people with cardiovascular disease, and those who have previously suffered a stroke or transient ischemic attack.
In such cases, sudden changes in blood pressure and circulation may increase the likelihood of an ischemic stroke caused by a blood clot, or in less common cases, a hemorrhagic stroke caused by bleeding in the brain.
Atrial fibrillation
Studies indicate that endurance athletes who engage in long-duration strenuous activities such as marathon running, long-distance cycling, and triathlons may have a higher risk of developing atrial fibrillation.
This condition is a known risk factor for stroke if left untreated. Dehydration and electrolyte imbalances during intense exercise may further increase these risks.
When should you stop?
Experts emphasize that exercise-related strokes remain rare and should not discourage people from being physically active.
Dr. Batia notes that “the health benefits of regular moderate to high-intensity exercise far outweigh the potential risks,” adding that consistent physical activity significantly reduces the risk of stroke, heart attacks, obesity, and diabetes.
Recommended physical activity
Health guidelines for adults recommend at least 150 minutes per week of moderate-intensity physical activity, or 75 minutes per week of vigorous-intensity activity.
Recommended activities include brisk walking, cycling, swimming, running, dancing, and strength training.
Individuals over the age of 40 or those with cardiovascular risk factors are advised to undergo a medical evaluation before starting intensive exercise programs, especially if they experience symptoms such as chest pain during exercise, unexplained shortness of breath, dizziness or fainting, palpitations, or extreme fatigue.
Experts stress that a simple health check can help detect hidden risk factors and ensure safe and effective exercise practices.
While very intense exercise may slightly increase the risk of stroke in limited cases, regular physical activity remains one of the best ways to protect heart and brain health and improve overall wellbeing provided it is done gradually, with proper hydration, and under medical guidance when needed.
