A stroke occurs when blood flow to part of the brain is blocked or interrupted, making it a medical emergency that requires immediate treatment. Common warning signs include sudden face drooping, arm weakness, and difficulty speaking. The B.E. F.A.S.T. method also highlights problems with Balance and Eyes, reminding people that Time is critical—calling emergency services right away can save a life.

Some strokes happen during sleep and are known as “wake-up strokes,” meaning a person goes to bed feeling normal but wakes up with stroke symptoms. These account for about 15–25% of ischemic strokes. Factors such as changes in blood pressure, increased blood clotting in the early morning, and untreated sleep apnea may contribute to this risk.

While not all strokes can be prevented, experts estimate that many are linked to modifiable risk factors. Healthy evening habits can support heart and brain health. Avoid eating heavy meals late at night, lying down immediately after eating, drinking excessive alcohol before bed, or consuming too much caffeine late in the day. A short walk after dinner and finishing your last meal two to three hours before bedtime may also help improve sleep and overall cardiovascular health.

Keeping a consistent sleep schedule is equally important. Aim for 7–9 hours of sleep each night and try to go to bed and wake up at the same time every day. Combined with regular exercise, a balanced diet, and managing conditions like high blood pressure, diabetes, and sleep apnea, these habits can help lower your overall stroke risk.
