Drowsiness after a heavy meal is due to

Options

A. Increased blood pressure
B. Decreased pulse rate
C. Reduced blood pressure
D. Increased pulse rate

Answer

**Step-by-Step Solution:**

1. **Understanding the Context**: After consuming a heavy meal, many people experience drowsiness. This phenomenon can be attributed to physiological changes in the body.

2. **Digestion Process**: When we eat, our body directs more blood flow to the digestive system (stomach and intestines) to aid in the digestion process. This increased demand for blood in the digestive organs can affect blood circulation in other parts of the body.

3. **Blood Flow Redistribution**: As blood is redirected to the digestive organs, there may be a slight decrease in blood flow to other areas, including the brain. This redistribution can lead to changes in blood pressure.

4. **Blood Pressure Changes**: The redirection of blood flow can cause a temporary drop in blood pressure. When blood pressure decreases, it can result in feelings of drowsiness or lethargy.

5. **Conclusion**: Therefore, the drowsiness experienced after a heavy meal is primarily due to reduced blood pressure as the body focuses on digestion.

**Final Answer**: Drowsiness after a heavy meal is due to reduced blood pressure.
