Cerebral infarction, commonly known as ischemic stroke, occurs when blood flow to part of the brain is suddenly blocked, leading to oxygen deprivation and potential loss of brain function.

Research indicates that strokes often happen at night or in the early hours of the morning—when blood becomes thicker and circulation slows due to the body's resting state. People with atherosclerosis or narrowed arteries are at higher risk. Recognizing early warning signs is crucial for prevention and timely treatment.

Here are five symptoms during sleep that could indicate a higher risk of stroke. If you experience any of these, it’s important to seek medical evaluation:

---

1. Sudden Numbness or Weakness on One Side of the Body

Waking up with a tingling sensation, numbness, or weakness—particularly affecting one side of the body—or struggling to move your arms or legs could be a sign of neurological dysfunction due to reduced blood flow to the brain. Slurred speech or difficulty expressing thoughts may also occur.

---

2. Unexplained Drooling During Sleep

Drooling while sleeping isn’t uncommon if you sleep on your side. However, persistent drooling even when lying on your back—especially if accompanied by facial asymmetry, headaches, or general fatigue—may point to decreased blood supply to the brain.

---

3. Unusual Headaches or Dizziness at Night

Severe headaches or sudden dizziness while resting—especially when accompanied by a spinning sensation or imbalance—should not be ignored. These may be early neurological signs of stroke.

---

4. Frequent and Unexplained Yawning

Yawning frequently at night, even when you’re not tired, can indicate low oxygen levels in the brain due to poor circulation. If you find yourself nodding off easily or yawning excessively while seated, consult a doctor.

---

5. Blurred Vision Upon Waking

Sudden blurry vision or temporary darkness upon waking could result from restricted blood flow through the internal carotid arteries. Though the symptoms may fade quickly, recurring episodes should be taken seriously.

Stroke Can Affect Young People Too

While many associate strokes with the elderly, cases among younger adults are on the rise. In some regions, including parts of Asia, stroke onset occurs nearly a decade earlier than in many Western countries—largely due to unhealthy lifestyle choices, including poor diet.

4 Food Categories to Limit for Stroke Prevention

Certain foods can increase your risk of stroke by contributing to high blood pressure, high cholesterol, and arterial plaque buildup:

1. High-Sodium Foods

Pickled vegetables, cured meats, and dried snacks are often loaded with salt. Excess sodium can raise blood pressure and damage blood vessel linings.

2. Organ Meats

Liver and other organ meats are rich in cholesterol. When consumed frequently, they may elevate blood lipid levels and contribute to arterial blockages.

3. Trans Fats

Common in deep-fried foods, baked goods, and processed snacks, trans fats raise harmful LDL cholesterol while lowering beneficial HDL cholesterol—making blood thicker and more prone to clotting.

4. Refined Sugars

Sugary beverages and sweets contribute to obesity, type 2 diabetes, and hypertension—all major stroke risk factors.

3 Key Habits to Prevent Stroke

1. Maintain a Balanced Lifestyle

Avoid staying up late, aim for consistent sleep, exercise regularly, and manage stress. Maintaining a healthy weight and stable blood pressure is critical.

2. Manage Risk Factors

Avoid smoking and limit alcohol. If you have pre-existing conditions like hypertension, diabetes, or heart disease, ensure they’re well controlled through regular treatment and monitoring.

3. Get Regular Health Checkups

Many strokes occur with little or no warning. Routine checkups and screenings can help detect silent issues before they become emergencies.

Final Thoughts
Stroke is a medical emergency—but early warning signs often appear. By paying attention to unusual symptoms, especially during sleep, and adopting preventive lifestyle habits, you can greatly reduce your risk. Stay informed, stay healthy—and never ignore what your body is trying to tell you.
