Electric Heating Pads vs. Wraps – What’s Better for Cramps?

how does heat help for cramps

There are many kinds of heating pads out there:

So, which heating pad is best for menstrual 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 also need to decide whether you’ll need it on the move, 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 don’t need a portable heating pad/wrap.

The best choice for you would be a regular small electric heating pad (either corded or cordless), 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).

Pro Tip

In long-term, the electric heating pads are more cost-effective than the heat wraps.

1. Mighty Bliss Heating Pad Most Comfortable

mighty bliss heating pad for cramps

Mighty Bliss Heating Pad – check today’s price on Amazon

  • 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 issued a refund.

2. UTK Infrared Heating Wrap Best Overall

My UTK infrared belt – View on Amazon 

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

The UTK heating wrap is the only one on our list using infrared heat therapy through carbon fiber and 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.

ThermaCare Heatwrapscheck today’s price

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.

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

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 Therapymy heating pad neck and shoulder wrap

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 is smells heavenly, but it can also be used as a cold pack.  A great way to relax, reduce stress, and relieve your pain.
