Heat Rash During Pregnancy: Causes, Symptoms and Prevention

Updated on 27 December 2023

There is no denying that the journey of pregnancy is no less than a metamorphosis for a woman. Her body undergoes a multitude of changes and adapting to these transformations can be challenging. As the mercury rises and your body undergoes remarkable changes, the risk of developing a heat rash during pregnancy increases.

In this article, we will explore the causes, symptoms, remedies and effective prevention strategies for pregnancy-related heat rash.

Symptoms

Heat rash, medically known as "miliaria," can be a bothersome skin condition that typically occurs in hot and humid weather. During pregnancy, this condition may be more common due to increased body heat and sweating.

Recognizing the symptoms of a heat rash is crucial to addressing the issue promptly:

1. Red Bumps

One of the primary symptoms is the appearance of small, red bumps on the skin. These bumps can be itchy and uncomfortable.

2. Prickling Sensation

Expecting mothers may experience a prickling or tingling sensation in the affected areas.

3. Increased Sweating

Heat rash often occurs in areas where sweat becomes trapped under the skin, such as in skin folds.

4. Irritation

The rash can be quite irritating and may lead to discomfort or a burning sensation.

Pregnant women may notice a heat rash in the following areas:

  • The crease between and beneath your breast

  • The crease where the lower abdomen bulge rubs against the top of your pubic area

  • The crease of your elbows

  • On your back, inner thighs or armpits

What are the Causes of Heat Rash During Pregnancy?

Understanding the causes of heat rash is essential for effective prevention and management. Here are five common culprits:

1. Hormonal Changes

Pregnancy leads to hormonal fluctuations, which can affect the body's ability to sweat and cool down efficiently.

2. Hot Weather

High temperatures and humid conditions can exacerbate heat rash, making it more likely to occur during the summer months.

3. Tight Clothing

Wearing tight or restrictive clothing can trap sweat against the skin, increasing the risk of heat rash.

4. Excessive Sweat

As pregnancy often leads to increased perspiration, the sweat can become trapped in skin folds, creating an ideal environment for heat rash.

5. Inadequate Ventilation

Poorly ventilated living spaces or clothing that doesn't breathe can contribute to the development of heat rash.

2. Loose Clothing

Opt for loose-fitting, breathable clothing to reduce friction and promote ventilation.

3. Stay Hydrated

Drink plenty of water to help regulate your body temperature and encourage proper sweating.

4. Cool Showers

Take cool showers to soothe your skin and reduce irritation.

5. Avoid Excessive Heat

Stay out of direct sunlight and reduce outdoor activities during peak heat hours.

6. Cornstarch or Oatmeal Powder

Apply these talc-free powders to keep skin dry and prevent friction.

7. Gentle Cleansing

Use mild, fragrance-free soap to avoid further irritation.

8. Pat, Don't Rub

When drying off after a shower, gently pat your skin instead of rubbing it.

9. Avoid Creams and Ointments

These can trap heat and exacerbate the rash.

10. Consult Your Doctor

If the rash during pregnancy persists or worsens, seek guidance from your healthcare provider.

Other Types of Skin Rashes During Pregnancy

4. Pemphigoid gestationis

This is a rare autoimmune skin disorder that can cause a hive-like rash on your midsection. It tends to appear suddenly during the second or third trimester and turns into blisters.
