Do Heating Pads Really Work for Period Cramp Pain Relief?

In a heat therapy for primary dysmenorrhea study by PubMed Central, they found that heating pads decreased menstrual cramping pain, but there's a catch.

This review looked at six different studies and found that using heat (like heating pads) helps reduce period pain in women. The heat worked better than fake heat pads that weren't actually warm. It also seemed to work better than pain-relief drugs.

What's the catch?

The catch is that we need to be careful about these results because there weren't many studies and they might not have chosen participants fairly.

The good news is that there are studies being conducted at the higher education level, and there are heating pad products out there that seem to be collecting more and more data, as more women are purchasing these heating pads.

So, do heating pads really work for menstrual cramping pain, or not?

This article will explain their potential effectiveness and provide guidance on proper usage to combat period cramping pain.

Key Takeaways

  • Heating pads increase blood flow and relax muscles which could help with period pain.
  • Periods are caused by uterine muscle contractions driven by prostaglandins which leads to lower abdominal pain, nausea and headaches.
  • Choosing the right heating pad—electric, microwaveable or hot water bottle—boils down to personal preference and all can work.

Understanding Period Cramps

Many people, especially younger women experience menstrual cramps which can be super intense. These cramps happen when the uterus contracts to shed its lining and can be super uncomfortable.

To manage these symptoms try using a heating pad, over the counter pain relievers, relaxation techniques like deep breathing or meditation, gentle exercises like walking or yoga and topical pain relievers like creams or gels.

Dr. Jane Doe, gynecologist at the Women’s Health Institute says, "Menstrual cramps are caused by the release of prostaglandins which makes the uterine muscles contract. Heating pads can help with this pain by increasing blood flow and relaxing the muscles."

Common Symptoms of Menstrual Pain

Menstrual cramps involve pulsing or gnawing pain in the lower abdomen sometimes extending to the lower back, hips and thighs. This pain usually starts 1-3 days before the period, peaks on the first day and subsides after 2-3 days. Other symptoms can be nausea, diarrhea, headaches and dizziness.

A study in the Journal of Women’s Health found that over 70% of women experience menstrual pain that interferes with daily activities. Knowing the symptoms can help you manage period pain better.

Causes of Period Cramps

Period cramps are caused by prostaglandins which trigger uterine muscle contractions. The intensity of cramps vary among women and is influenced by the level of prostaglandins in the body.

Dr. Sarah Johnson, reproductive endocrinologist says, "Higher levels of prostaglandins means more intense menstrual cramps. That’s why some women have severe pain while others have milder discomfort."

How Heating Pads Relieve Period Pain

Heating pads can increase blood flow to the muscles, bring in more oxygen and relax tense muscles and spasms. This is quick relief without medical intervention.

Dr. Michael Roberts, pain management specialist says, "Applying heat to the abdominal area can reduce pain by increasing blood flow and reducing muscle tension. It’s a simple method many women find helpful."

Benefits of Heat

Heat increases blood circulation, reduces inflammation and promotes relaxation. Some studies suggest heat therapy can be as effective as pain meds for period pain relief.

A study in The Lancet found that women who used heat therapy for menstrual cramps had more pain reduction compared to those who used over-the-counter pain meds.

Scientific Backing for Heating Pads

Studies show that heat from heating pads can reduce menstrual pain, so yes, use them during your period.

Research in Obstetrics & Gynecology found that applying heat at 104-107 degrees Fahrenheit can reduce menstrual pain, so it’s a non-medication option.

How to Choose a Heating Pad for Menstrual Cramps

Choosing the right heating pad depends on personal preference and needs. Electric heating pads have adjustable temperature settings, microwaveable pads have quick heat and hot water bottles have the traditional and cost effective option.

Electric Heating Pads

Electric heating pads have precise temperature control and often have safety shut-offs and adjustable heat settings.

Dr. Emily White, physical therapist says, "Electric heating pads are great for providing consistent heat over a longer period. The ability to control the temperature makes them versatile for period pain."

Microwaveable Heating Pads

Microwaveable heating pads are quick and easy relief, usually filled with rice or flaxseed that retain heat well.

Hot Water Bottles

Hot water bottles are traditional, flexible and cost effective way to relieve pain, often wrapped in a towel for milder heat application.

Dr. Laura Kim, family physician says, "Hot water bottles are perfect for those who prefer a natural and simple approach. They are easy to use and warm.

How to Use Heating Pads Effectively

To use a heating pad for period pain relief, place it on your lower abdomen or area of pain for 15-20 minutes at a time. Adjust the temperature to your comfort and use a timer to avoid overuse.

Dr. Robert Lee, pain management specialist says, "Start with the lowest heat setting and increase as needed. Listen to your body and never use a heating pad for more than 20 minutes at a time."

Best Practices Using Heating Pads

Start with the lowest heat setting and increase as needed. Always use a cover or cloth between your skin and the heat source to avoid burns.

Here are some easy-to-follow steps:

  1. Start your heating pad on the lowest heat setting and only make it hotter if you need to.
  2. Keep checking to make sure it’s not too hot, so it helps your pain without making it worse.
  3. Always put a cloth or cover between your skin and the heating pad to avoid burns.

If you’re using a hot water bottle, wrap it in a towel to keep it from getting too hot against your skin.

No matter what kind of heating pad or hot water bottle you use, don't fall asleep with it on, as this can cause burns.

Heat with Other Remedies

Heat pads with essential oils, massage or warm baths can increase pain relief. Alternating the placement of the heat pad can prevent over exposure to one area.

Dr. Maria Sanchez, integrative medicine specialist says, "Using essential oils like lavender or chamomile with heat therapy can increase relaxation and more pain relief."

Alternative therapies like acupuncture, acupressure and herbal supplements, such as Cramp Bark can help as well. That's where UnCrampMe gummies for period cramps comes in.

Dr. Karen Green, nutritionist says, "Incorporate anti-inflammatory foods like fish, nuts and leafy greens in your diet to reduce period pain."

Alternative Therapies

Alternative therapies like acupuncture and acupressure can help with menstrual cramps. Herbal supplements like ginger, turmeric and fennel are anti-inflammatory and can be effective for period pain.


Heating pads are a convenient and affordable way to relieve period cramps. While there is some scientific evidence to support it, combining with other remedies and lifestyle changes may be the best.

Dr. Alice Brown, holistic health practitioner says, "The key to manage menstrual pain is combination. Heating pads with other lifestyle and alternative therapies can provide total relief."
