Menstrual cramps often catch us at the most inconvenient times and make you wish you could just curl up in the fetal position on the couch all day while making sarcastic remarks at everyone (or just crying).

If you are looking for a natural solution, an electric/microwaveable heating pad for cramps is the fastest pain-relieving tool you’ll find.

In this post, you’ll find the 7 best heating pads for cramps, according to hundreds of reviews online. These include portable heating pads (microwaveable), stick-on heating pads, and traditional electric heating pads.

👉 These heat pads can also be very helpful for Endometriosis pain!

As long as you keep it on your lower abdomen – you’re good.

How to Choose a Heating Pad for Cramps

There are many kinds of heating pads on the market:

• Small electric heat pads
• Large heating pads
• Portable heating pads
• Microwaveable heating pads
• Moist heating pads
• Stick on Wraps

So, which heating pad is best for menstrual cramps and period back pain?

In our experience, a heating pad for cramps should be small, but large enough to cover your low abdomen (or lower back). You’ll need to decide whether you want to use it on the go, or you plan to use it at home while lying down and relaxing.

If you suffer from excruciating and debilitating period pain and cramps (when you can’t even move) – you may not want to choose a microwaveable wrap, because the heat may not last long enough for substantial relief.

The best choice for you would be a regular small electric heating pad (either corded or battery operated), with either dry or moist heat.

 If your pain is bearable, and you want to stay on the move – we suggest a portable heating pad that you can easily hide under your clothes and go about your day.

Regular electric heating pads are usually kept at home, and when you feel the painful cramps starting, you plug them in (or turn them on with the remote if they are cordless), choose a heat level and treatment time, and relax.

On the other hand, heat wraps (patches) are so small you can carry them in your bag, and they don’t need a power supply to provide almost immediate heat to relieve your pain, (but you can only use them once).

Comparing the best heating pads, wraps and belts for menstrual cramps, according to type, features, temperature, and price.

1. Mighty Bliss Heating Pad Most Comfortable

• Size – 12″x24″
• Weight – 1 pound
• Auto shut off – 2 hours

The Mighty Bliss large heating pad is large enough to cover your stomach and lower back (if you wrap it around you) and is made with a soft microplush cover (used in those comfy winter pajamas).

It can be used as both a dry and moist heating pad, and It is machine washable.

To use it as a moist one, you simply dampen it with water by patting the surface with a wet sponge or cloth. Or you can use a spray bottle to apply a fine mist.

However, for some customers, the heat was not consistent as promised and didn’t stay warm until the 2-hour shut-off. Customer service then replaces their pad or issues a refund.

2. UTK Infrared Heating Wrap Best Overall

• Size – 7 x 48 x 0.5 inches
• Weight – 1.02 pounds
• Auto shut off – 3 hours (3 time settings)

The UTK heating belt is the only one on our list using infrared heat therapy through Jade stones.

We’ve found that infrared technology is the best form of heat you can use at home – and the most natural one as well.

Infrared light energy (IR rays) penetrates deeper into your aching lower abdomen and lumbar back and boosts blood circulation to the area.

This promotes the speedy arrival of pain-relieving and healing blood components – without any side effects.

The corded belt is EMF-free, and you can set the temperature (up to 150 F!) with the corded controller.

Another unique benefit here is the above-average weight (caused by the Jade stones), which helps push the heat even better when you use it lying down.

3.  Sunbeam XL Heating Pad with UltraHeat Technology Budget Friendly

• Size – 24 x 2.95 x 12 inches
• Weight: 1 pound
• Auto shut off – no

The Sunbeam heating pad uses UltraHeat Technology to maintain consistent heat and has a slide controller with 3 heat settings: Low – 90 F / Medium – 95 F /High – 100 F

It’s a basic (and low cost) heating pad, with no moist heat therapy option or a timer.

It does not shut off automatically and keeps working on and on until you shut it off. Some people are looking for this exact feature.

We recommend not to use one of bare skin.

✅ Price – Check this page on Amazon to see if it’s still less than $20.

And now, the best portable (cordless) heating pad for menstrual cramps:

4. Sunbeam Body-Shaped Heating Pad Best Cordless

• Size – 11″ x 20.5″
• Weight: 1 lb.
• Auto shut off

The Sunbeam body-shaped heating pad is ideal for cramps and pain because it can be wrapped around your lower abdomen via the flexible Velcro straps (which extend up to 70 inches).

This on-the-go wearable heating pad comes with a removable hot (microwaveable) and cold gel pack or a 9 feet long cord, if you want to use it while resting, and it has 5 heat settings.

Sunbeam Body Portable S Heat Pad Pros

1. Moist heat option
2. It stays in place thanks to the Velcro straps
3. The entire pad gets heated
4. Wraps entire stomach
5. Feels comfortable
6. Heats up quickly

Cons

1. The gel pack requires heating in a microwave
2. Can’t be used on bare skin (too hot)

And now, for the ultimate portable heat wraps for menstrual pain:

5. ThermaCare HeatWraps Best Stick-On

• Dimensions: 5 x 5 x 5 inches
• Weight: 3.2 ounces

The Thermacare reusable heat pads for period pain are specifically designed for cramps, because they stick to your underwear discretely, cover the entire painful area, and no one will know they are there.

Through our research, these sticky, small, and cordless heating pads are far more comfortable than heating pads, but while they will last for 8 hours – they are made for one-time use only.

(This is why I recommend buying a few of them upfront – see the pack of 9 HERE).

The Thermacare heat wraps are air-activated. You stick them to your underwear, open the pouch and it starts to warm up immediately. They are ultra-thin, comfortable, and discreet.

I would give them my highest rating if it weren’t for the fact that you have to keep buying them over and over and the price can add up.

✅ Price – Check price on Amazon.

Thermacare Heatwrap Pros

1. Stays hot for 8 hours consistently
2. Unnoticeable under clothes allows comfortable mobility – ideal for work and house chores

Cons

1. It May feel a bit bulky
2. One time use

6. Thermalon Microwave Activated Heating Pad Best Moist

• Size: 9″ x 12″
• Weight: 1.5 pounds

The popular Thermalon microwave-activated moist heating pad is flexible (conforms to body shape) and delivers consistent heat distribution – without wires, USB, or controller.

It even has pockets to warm your hands or feet!

The material (Polyester and Spandex) deters mold or bacteria (which is a side effect of rice heating pads) and can be washed and reused for years.

Users confirm that this budget-friendly heat pad is odor-free and fast-acting, and all you have to do is heat it up in your microwave for 1-2 minutes, and enjoy the heat for 20-30 minutes.

✅ Price – best price can be found on Amazon.

Microwaveable Heating Pads for Cramps

Here are two more high-quality heating pads found during my research, both are microwaveable:

1. My Heating Pad – Hot Therapy Pack – Soothing Heat Therapy

It’s a multi-purpose heat pack (12 X 6 inches) that weighs about 2.5 lbs (to keep some pressure on your abdomen) and feels very nice on the skin.

You simply heat it in your microwave and you’re good to go. It’s handmade in the USA and is eco-friendly and pet safe.

2. Sacksy Thyme Ultra Premium All Natural Microwavable Aromatherapy Heating Pads

This natural aromatherapy sack (22 x 7.5 inches) is best for natural living enthusiasts (plus, it’s cute!).

It’s made with 100% cotton in the USA and the sack contains organic flax seed, cherry pits, and herbal filler (lavender, eucalyptus, cherry, and lemon verbena).

When you heat it in the microwave it smells heavenly, but it can also be used as a cold pack.  A great way to relax, reduce stress, and relieve your pain.
