World Stroke Day 2025: Strokes are often seen as sudden medical emergencies that strike without warning. But neurologists say that in most people, a stroke is not an accident, it is the end result of years of quiet damage to the brain’s blood vessels. This damage is happening more than ever before. Stroke has become a major public health crisis in India, claiming a life approximately every four minutes. Based on the latest reports from the Indian Stroke Association, the country records an estimated over 1.8 million new stroke cases annually. This high incidence rate confirms stroke’s position as one of the top three leading causes of death and disability across the nation.
As per experts, the major reason behind the rise in stroke cases especially in India is due to a combination of three everyday factors: excess salt, excess sugar and never ending stress.
According to Dr. Pinky Chhatterpal, Consultant – Neurology at Fortis Hospital Noida, strokes don’t happen out of nowhere. In most cases, a stroke comes after years of stress on the brain’s blood vessels, not all of a sudden. “Most strokes are built slowly over years, not in a day,” she said. “People think it is sudden, but the body is always giving warning signs.”
Salt-heavy diets are pushing blood pressure to dangerous levels
Salt has been part of the human diet for centuries, but modern eating habits have sharply increased its intake through packaged and restaurant food. Dr. Chhatterpal explained that this extra sodium gradually makes blood vessels stiff and narrow, which raises blood pressure which is the single biggest risk factor for stroke.
Due to hypertension, the heart and arteries work harder, and over time the inner lining of blood vessels weakens. Even a small clot or blockage under these conditions can stop blood flow to the brain and trigger a stroke.
She said the issue is no longer limited to senior citizens. Many people in their 30s and 40s, especially those working long hours and eating quick, ready-made meals are now showing very high blood pressure. Regular intake of processed foods like chips, namkeen, instant noodles, rolls, cloud-kitchen curries and frequent restaurant food keeps salt levels high in the body. Unless people make a conscious effort to cut down salt, the risk keeps increasing with age.
Sugar is silently attacking blood vessels
Apart from salt, excessive sugar intake has become another major driver of stroke risk. Added sugar is present not only in desserts and cold drinks, but also in ‘healthy-looking’ items like breakfast cereals, protein bars, juices and packaged breads. Over time, high sugar intake leads to weight gain, inflammation and type 2 diabetes, all of which directly damage blood vessels.
Dr. Chhatterpal said that increased blood sugar narrows and weakens arterial walls, including those supplying the brain. When combined with high blood pressure, the damage becomes more rapid and severe. People with uncontrolled diabetes are significantly more vulnerable to both clot-related and bleeding strokes.
“The mix of hypertension and diabetes is particularly dangerous,” she said. “These two conditions together accelerate the damage to arteries at multiple levels,” she further added.
Chronic stress increases the risk
Even if people manage their diet, stress still acts as a major hidden trigger. Today’s work culture keeps many adults in a constant state of alertness because of deadlines and lack of rest. Dr. Chhatterpal explained that stress hormones like cortisol and adrenaline raise blood pressure and heart rate. When stress continues for months or years, the heart and blood vessels stay under constant strain.
The body also repairs itself more slowly during prolonged stress, which allows more damage to build up. Stress further adds to stroke risk by pushing people toward unhealthy habits like eating processed food, skipping exercise, sleeping less and depending on caffeine or sugar to get through the day.
“Stress is not just mental,” Dr. Chhatterpal said. “It has very real physical effects on blood vessels and the heart. When you combine stress with unhealthy food habits, that is when the danger rises sharply,” she further added.
The stroke burden is rising because daily habits are worsening
Neurologists say the lifestyle of urban adults today is such that it will increase stroke risk. Long sitting hours, irregular meals, takeaway food, fewer vegetables, high sugar beverages, late nights and constant phone-driven stimulation this becomes a loop. Unhealthy food choices raise BP and blood sugar, stress worsens both, poor sleep blocks recovery, and the brain gradually loses vascular resilience.
This results in more people reaching emergency rooms with paralysis, sudden speech loss, facial drooping or confusion which are all signs of a stroke.
Preventing stroke is far easier than treating one
Dr. Chhatterpal explains that the effects of a stroke can be disabling as it affects speech, movement, coordination and memory. Rehabilitation may take months or years and may still not restore life like before. Preventing the damage in the first place is far more effective than trying to reverse it later.
She said prevention does not require extreme measures. Simple and consistent steps are enough to reduce the risk significantly:
1) Cut down salt and processed food
Cooking at home, reading labels, avoiding daily packaged snacks and reducing restaurant meals can bring sodium levels down over time.
2) Reduce sugar intake
Replacing sweetened beverages with water, limiting desserts to occasional treats and avoiding products with hidden sugars lowers vascular stress.
3) Move every day
Even 30 minutes of walking or short breaks during work hours improve blood flow and blood pressure regulation.
4) Consciously manage stress
Brief breathing exercises, quiet pauses between tasks, reduced screen noise and protected sleep hours allow the stress response to calm down.
5) Monitor health parameters regularly
Checking blood pressure, blood sugar and cholesterol every few months helps detect silent risk before it turns into disease.
Strokes are preventable in most people
Dr. Chhatterpal said that many strokes can be prevented through basic lifestyle changes. “You do not need a drastic transformation. Small and steady corrections can protect the brain over time,” she said.
She added that brain health decides how well a person can think, work, move and live independently. Daily choices like what we eat, how we rest, and how we handle stress decide whether the brain stays safe or becomes weak. Her message is that the mix of salt, sugar and stress is not harmless just because it is common. It is silently increasing stroke risk in millions of people. Noticing this connection early, and acting on it, can protect both life and long-term quality of living, especially after the age of 40.
