What You Should Know About Heating Pads

It is a well-known phenomenon that if you sip a cup of hot coffee, soak in your warm bath or cozy up in your heated blanket; you will feel soothed instantly. The unexpected wave of ease and comfort is not your imagination because heat can help relax tense and stiff joints and muscles.

Plenty of experts suggest the use of products like heating pads or hot gel packs to relieve arthritis and chronic pain for injuries like sprains, strains, and bruises.

Whenever your muscles ache or feel sore, often the culprit is lactic acid. Your body produces this chemical when your muscles don't receive sufficient oxygen. If the blood flow to your damaged muscles decreases, the lactic acid accumulates in this area.

The application of heat to an aching area tends to facilitate the flow of blood to this spot, which removes the buildup of lactic acid waste and lowers your pain.

What Is A Heating Pad

A heating pad is a padding or cushion used to warm up parts of your body to relieve and manage pain. Application of a heating pad causes your blood vessels in the aching area to dilate and enhances perfusion to your targeted tissue.

Chemical Heating Pad

A chemical heating pad is an ideal choice especially if you are on the move as it is disposable.

A chemical heating pad warms up within a few seconds when a tiny metallic piece presses against sodium acetate which triggers a chemical reaction which leads to the crystallization process. Most of these pads stay warm for at least a few hours.

You can reuse the heating pad by simply submerging it in hot water and bringing it back to room temperature. Most of them are small in size, and you can wear them directly on your skin. But make sure you read all the instructions first because you have to wear a few models on top of the clothing.

Microwavable Heating Pad

A microwavable heating pad comprises an anti-flammable cloth usually filled with some grain, gels, or other heat-retaining material. Grains used most often are barley, rice, and wheat. For making these pads for effective and soothing, essential oils like vanilla or lavender mix with the grains.

Infrared heating pads are specifically designed to make use of Far Infrared Therapy, which often utilizes specialized and focused carbon fibers for giving off infrared rays. These rays safely penetrate your skin surface to promote circulation of blood which helps heal damaged and aching tissues more swiftly.

Infrared heating pads are safe as infrared heat does not increase blood pressure or cause burns. This reason is why they are prevalent in different medical facilities such as hospitals, nursing homes, neo-natal units and private homes.

Different Sizes Of Heating Pads

Heating pads come in plenty of different sizes. These include small, medium, large and king size. Different sizes are suitable for different situations and different parts of the body.

Dry Vs. Moist Heat

Heat therapy is quite beneficial when used correctly. It is suitable for different types of pain ranging from stiff muscles to chronic back pain. Heat therapy products are preferable to other invasive kinds of treatment.

The two main kinds of heat therapy are dry heat and moist heat. There are some differences between these two heat therapies that you should know before you choose one over the other.

Dry Heat

Dry heat therapy draws moisture out of your skin. The upside of dry heat is that a lot of people often find it extremely convenient and easy to use. The downside, however, is that it is likely to dehydrate your skin. A majority of dry heat products are usually electric. You can even find dry heat saunas.

If you prefer the feel of dry heat on the skin, make sure that you use it at an appropriate temperature. If your skin feels too dry or dehydrated, then limit the use of dry heat therapy or move to moist heat. Most heating pads offer dry heat and are more convenient and long-lasting compared to moist heating pads.

Moist Heat

Moist heat, on the other hand, is less likely to lead to skin dehydration. It is available in many different forms such as hot baths, steam towels, and moist heating pads, etc. Moist heat helps enhance tissue elasticity which makes it perfect for people with aging or dry skin.

Warm towel

A majority of experts recommend the use of moist heat over dry heat, which is because it is less likely to cause skin irritation and there is no risk of skin dehydration; also, it penetrates more deeply into your skin.

A moist heating pad is more effective as it uses moisture effectively to penetrate aching or painful areas. Also, moisture is a better at heat conduction compared to air. Many comparisons have proved that moist heat is about thirty times more effective than dry heat.

This effect implies that moist heat usually penetrates deeper into painful and sore areas that dry heat may not reach. A moist heating pad provides faster and deeper healing. Also, sore or aching tissues tend to tolerate moist heat better at higher temperatures compared to dry heat.

Different Reasons For Using A Heating Pad

Heating pads are usually considered one of the most effective treatments for different types of body aches. However, not a lot of people know how convenient and valuable they can be lowering various body pains. Here is a list of different uses of a heating pad.

Reduces Lower Back Pain

Lower back pain is one of the most common ailments that people suffer in their life. A majority of cases of lower back pain are muscle-related; meaning the increase of blood flow to the region will bring quick relief.

Reduces Lower Back Pain

A heating pad warms the muscles, which relaxes and dilates the blood vessels. This effect helps bring more oxygen, blood flow, and nutrients to the aching area. This effect not only reduces pain in your muscles, but also in the tendons, joints, and ligaments. The heat also helps reduce muscle spasms.

Lowers Headache

Most people experience headaches frequently. It is a throbbing on the side or front of the head. The nerve endings in the body are conductors that transmit pain signals to your brain.

A heating pad reduces a headache by generating extreme temperature. When your nerve endings are under stress, high temperature eases the pain as the nerves respond well to fluctuations in temperature. Heat relaxes muscles and reduces inflammation.

Reduces Neck Pain

If neck pain is induced by overworked or tired muscles, using a heating pad can arouse sensation in your skin, decreasing the neck pain. If triggered by stress and your neck muscles remain tense for long periods of time, applying a heating pad will help your muscles relax.

Lowers Knee And Hip Pain

Knee and hip pain are often debilitating and are typically triggered by joint problems. When these pains are caused by soft tissue or damaged muscle, applying a heating pad tends to lower the sore stiffness and enhance the flexibility around the damaged joint or area.

How To Use A Heating Pad

You can use a heating pad for different types of body pains.

For example, if you have pain in your upper or lower back, you can lie down flat, on any firm surface such that the back makes complete contact with your heating pad so that it covers the region where the pain originates. Always place a piece of fabric or clothing between the heating pad and your skin to prevent burns.

Lie down slowly on the heating pad so that your body can get accustomed to the change in temperature. Then sit up and maintain this position for 5 seconds every time during the initial 2 minutes of this treatment; this will allow your back muscles to absorb the heat effectively.

Do not use a heating pad for over an hour at a time irrespective of the nature of your injury.

  • Unplug it when the pad is not in use.
  • Follow the manufacturer’s instructions.

Safety Issues

There are several concerns and issues about the safety of heating pads. These issues range from getting burned to more grave ones like being electrocuted by the improper use of heating pads.

The quality of heating pads is of paramount importance, and you should know that many substandard models do not come with built-in overheating protection.

One chief health issue is an electromagnetic field; it is radiation emitted by the heating pads. Although most electrical devices emit some level of the electromagnetic field, it is often quite low to pose serious health risks.

However, heating pads tend to emit more radiation, and this is why it is important that you pay attention to a heating pad’s specifications when you are buying one. Exposure to radiation can impair your immune system.


Another issue is related to the extended use of heating pads. You can attribute this to the efficacy the heating pad and of the treatment itself.

You should bear in mind that not all models of heating pads improve efficiency, which mainly happens because of the lack of proper research and development, the use of cheap materials or, at times, even flaws in the production process. The prolonged use of heating pads can lead to inflammation of tissues which can defeat its purpose.

Heating pads can also cause a fire if you don't use it with caution. There are many reasons why this may happen such as:

  • Sparking from the plug or wiring
  • Frayed wires
  • Holes in the cloth covering
  • Absence of auto shut off mechanism
  • An inadequately functioning off/on switch or improper temperature control

Therefore, when you buy a heating pad, make sure it has all the necessary safety features. It is also important to read all the manufacturer's guidelines before use and to use the product with caution.
