Heat Exhaustion in Pregnant Women

Heat Exhaustion During Pregnancy: Increased Vulnerability

Heat exhaustion is a condition that occurs as a result of overheating and significant loss of fluids and salts through sweating. Pregnant women are especially vulnerable to this condition because of the physiological changes taking place in their bodies. It is important to know the symptoms and take preventive measures, as heat exhaustion can quickly progress to the more dangerous heat stroke.

Why do pregnant women overheat more easily?

• Elevated basal temperature: Due to hormonal changes and an accelerated metabolism, a pregnant woman's body temperature is normally slightly higher.
• Weight gain: Additional weight requires more effort for any activity, generating more heat.
• Increased blood volume: The cardiovascular system is already working under increased load, making it harder to adapt to heat.
• Higher fluid needs: Pregnant women become dehydrated more quickly, which is a key factor in the development of heat exhaustion.

Symptoms and First Aid

The symptoms of heat exhaustion in pregnant women are the same as in the general population and are described in detail in the article "Heat Exhaustion". They include profuse sweating, weakness, dizziness, nausea, and headache. The skin is usually pale and moist.

When these symptoms appear, you should:

1. Immediately move to a cool, air‑conditioned environment.
2. Drink plenty of cool water or electrolyte‑containing beverages.
3. Loosen or remove tight clothing.
4. Apply cool compresses to the skin.

If the condition does not improve within 30–60 minutes, seek medical attention, as it can be dangerous for the fetus.
