Expecting Moms Ask: Are Heated Jackets Safe During Pregnancy?
“Last year, I bought a heated jacket to stay warm and stylish in freezing weather. I loved its sleek design and impressive heating performance. Now that I’m pregnant, I’m unsure whether wearing a heated jacket is safe for me and my baby.”
Getting through cold winters is a challenge for many. Low temperatures can make us sluggish, reduce productivity, and even increase the risk of illness—especially among the elderly. To combat the cold and improve comfort, more people are turning to heated gear, including space heaters, electric blankets, and heated apparel.

Among these, the heated jacket has become a winter essential. It delivers targeted warmth to key areas, such as the back, chest, and shoulders, making it increasingly popular in recent years. As more people discover its benefits, one common question continues to surface: is it safe to wear a heated jacket during pregnancy?
That’s exactly why we wrote this article—to help expectant mothers understand the safety and suitability of heated jackets during pregnancy.
How Do Heated Jackets Work?
Heated jackets rely on advanced heating technology to generate warmth. They typically consist of built-in heating elements and a rechargeable battery. In simple terms, a battery connects to the jacket via a cable, supplying power to the heating elements, which produce heat at the press of a button. Most heated jackets are designed to work only with specific, compatible batteries for safety and performance.
Is it Safe to Use a Heated Jacket During Pregnancy?
Heated jackets are a popular choice for staying warm outdoors, especially thanks to their excellent performance and built-in safety features. Most manufacturers prioritize user safety to provide the best wearing experience and maintain product competitiveness. In general, experts agree that heated jackets are safe for everyday use.
However, when it comes to pregnancy, the situation is a bit different. While these jackets offer warmth and convenience, we do not recommend their use during pregnancy due to potential risks.
1. Temperature Concerns
Most heated jackets come with adjustable heat settings, allowing users to customize warmth for various weather conditions. This feature is great for general users, but it may pose a concern for pregnant women.
Pregnant women are more sensitive to external temperature changes. Sudden spikes in body temperature may impact fetal development. Health experts generally recommend that pregnant women avoid raising their core body temperature above 38°C (100.4°F), as overheating can negatively affect the baby
While many heated jackets offer low-temperature settings (e.g., 30°C), prolonged use or poor ventilation may still cause localized overheating, increasing the risk of discomfort or unintended effects.
2. Radiation and Electromagnetic Fields
Heated jackets are powered by batteries, which emit low levels of electromagnetic radiation. This radiation is typically minimal and safe for general users—it may even help with blood circulation.
However, during pregnancy, it’s wise to avoid any unnecessary exposure to electromagnetic fields (EMFs) as a precaution. Although experts consider the magnetic fields generated by heated jackets to be negligible, there’s still a possibility of mild side effects such as headaches, dizziness, or nausea in sensitive individuals.

Moreover, prolonged exposure to EMFs may interfere with the immune system or affect prenatal development, which is why healthcare professionals recommend limiting exposure during pregnancy.
3. What Do Experts Say?
Heated jackets function similarly to heated blankets. Previous studies have found that prolonged use of heated blankets during pregnancy may increase the risk of pregnancy complications or affect fetal growth.
While direct evidence on heated jackets is limited, the principles are comparable—continuous exposure to heat or electrical current near the body may pose a potential risk during pregnancy.
Conclusion
While heated jackets are generally safe and effective for everyday warmth, they may not be suitable during pregnancy due to temperature sensitivity, potential EMF exposure, and limited supporting research on long-term safety for expectant mothers.
If you're pregnant and feeling cold, it's best to stick with traditional layering techniques—like thermal wear, wool coats, or fleece jackets—that don’t involve electrical components.
Always consult your healthcare provider before using any type of heated product during pregnancy.
