The use of heat for comfort in labor is not a new thing at all. Though most hospitals do not have ready access to sources of heat for comfort in labor. The most common type of heat is a heating pad, water bottle or rice sock. With the exception of the heating pad, these actually lose heat as they go, meaning that they need to be reheated, but are safe to sleep with because of this fact.

Heat is also great for helping you relax.

This might be a specific location, like a tight muscle or it might be just used generically to help you relax, such as a warmed blanket or a warm tub or shower. You need to figure out what works for you at the moment, but you might already have a good idea from your everyday life. If you are a big fan of a heating pad or other source of warmth, this might be a great thing to add to your birth plan.

Where to Use Heat in Labor

Heat can be used at any point in labor or even for comfort at the end of pregnancy. Common places to put heat sources would be:

  • Back: If you are experiencing back labor, using a heat source can feel better and relieve your pain. You can also use this in conjunction with cold, alternating them for even better pain relief.
  • Pubic Bone: You might feel a lot of tightness or pressure at your pubic bone. This is particularly true if you've suffered from Symphysis Pubis Dysfunction (SPD) in pregnancy. Heat can help you relax and increase your mobility.
  • Neck: Using warm compresses on the neck is something that many people use to help them relax. There is no greater time that you need for relaxation than in labor.

"I was really hot in labor, but having a hot pack on my lower back felt amazing," said Ash, a new mom. "My doula suggested it and I didn't think it would help but it felt amazing.

She would change it as it lost it's heat. My husband used a cool rag on my face. It sounds weird, but it was crazy helpful."

Keeping Warm in Labor

Sometimes you may get chills in labor. Heat can help warm you in labor and reduce feeling chilly. Simply take your heating pad or rice sock and cuddle up with it, wherever it feels best. Hospitals may also be able to offer you heated blankets for full body coverage. Remember to test the heat source with your hand. Sometimes you need to wrap it with a towel or two to make it more comfortable to the touch.

If you don't have access to a rice sock or heating pad, there are other choices for you:

  • warm blanket (open or closed)
  • hospital glove filled with warm water
  • warm shower or tub

When Not to Use Heat in Labor

The good news is that we don't believe that there is a risk to using heat in labor as far as your labor progress goes. There have not been a lot of studies on the topic specifically, though a very small study showed it was not problematic, nor do we believe it will cause problems with the fetal monitoring.

Remember not to use heat or cold on skin that does not have feeling, such as areas that are numbed from an epidural. This can cause you to burn yourself accidentally.  It is important to be very careful using any source of heat if you have an epidural. You should never put something heated on skin that is numb from an epidural, you may get a burn if you do that. It can also cause you to overheat, since an epidural changes how your body dissipates heat. The same warning goes for a mother with a fever in labor, heat may not be appropriate.
