Cold Weather Linked to Increased Stroke Risk, Experts Warn

Cold Weather Linked to Increased Stroke Risk, Experts Warn

When it gets cold outside, your body's blood vessels squeeze tighter to stay warm.

This makes your blood pressure go up, and your blood can become thicker, like syrup.

Thicker blood is more likely to form clots.

If a clot blocks a blood vessel in your brain, it can cause a stroke.

Doctors notice more people having strokes when the weather gets cold, especially after holidays like Diwali.

People who are older or already have health problems like high blood pressure or diabetes are at even higher risk.

To stay safe, it's important to stay warm, keep moving, manage your health conditions, and know the signs of a stroke like sudden weakness or trouble speaking.
