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

Thermacare Heatwrap Pros

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


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

How Do You Apply ThermaCare?

Ensure the skin in your pain area is clean and dry, without skin moisturizers or lotions. Then you position the wrap by lightly pressing tabs into place on your skin.

Make any needed adjustments and rub over adhesive tabs firmly to “lock” in place.

5. UTK Infrared Heating Wrap – Deep Penetrating & Weighted

Get a 15% discount on this Amazon page!

The UTK heating wrap is the only one on our list using infrared heat therapy through carbon fiber and Jade stones, though we believe 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) penetrate 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 controller. See suggestions below:

  • Warm temperature range (103°F~109°F)
  • Low-temperature range (110°F~119°F)
  • Medium temperature range (120°F ~129°F)
  • Medium-High temperature range (130°F ~139°F)
  • High-temperature range (140°F~149°F)
  • Very High-temperature range (150°F ~159°F)

Dimensions: 7 x 48 x 0.5 inches

Electric Heating Pads vs. Heat 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?

  1. a menstrual cramp heating pad should be small, but large enough to cover your low abdomen.
  2. You’ll have to decide whether you’ll need on the move, or you plan to use it at home while lying down and relaxing.

👉 If you usually 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 must function with it – I would 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.

Menstrual Heating Pads: More Options

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. 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. A great way to relax, reduce stress, and relieve your pain.

Heat for Cramps FAQ

How Does Heat Help with Cramps?
