Muscle pain, joint pain, stiffness, and body aches can limit your daily activity and impact your quality of life. Luckily, there's no need to suffer in silence or rely solely on habit-forming medication!

Purpose of Guide

Heat and cold therapy (sometimes referred to as ice and heat therapy) are non-pharmacological and cost-effective treatments for sports injuries, joint stiffness, muscle cramps, back pain, and aches.

In this essential guide, you'll learn about the science behind cold and heat therapy for pain relief. We'll show you how to soothe your pain without side effects.

What is heat therapy?

Heat therapy – thermotherapy – is the practice of applying superficial heat to joints, tendons, ligaments, and muscles. Heating treatment relieves stiffness and muscle spasms by dilating the blood vessels and encouraging relaxation. It stimulates your self-healing mechanisms by improving the flow of oxygen and nutrients to your tissues and the removal of waste products. Heat may also enhance relaxation and relieve stress, taking the edge off your pain.

Hot water bottles, gel packs, microwavable wheat bags, and booties evenly distribute heat to reduce inflammation and improve circulation and flexibility. 

However, heating treatment isn't suitable for a new injury or acute inflammation.

What is cold therapy?

In some cases, heat therapy isn't enough to soothe the pain. Joint inflammation, acute injuries, and migraines respond better to cold therapy. Cold therapy – also known as cryotherapy – is the use of ice or cold packs to treat pain and inflammation.

Our gel packs, eye masks, microwavable wheat bags, and foot warmers double as ice packs when you put them in the freezer. However, always put a cloth between your skin and the cold pack to avoid freezer burns!

What is the science behind it?

Heat and cold therapy relieve pain and promote healing – but they work in opposite ways1.

Heat therapy increases blood flow by dilating blood vessels2. It relaxes muscle fibres, increasing range of motion and reducing soreness and stiffness. Research shows applying heat deactivates pain at a molecular level by blocking pain signals to the brain3. Studies have found it helpful for back pain4, sore muscles after exercise5, and joint pain – including temporomandibular pain6.

Cold therapy stimulates vasoconstriction, slowing blood flow and reducing tissue damage. Research shows applying cold to the body relieves pain by temporarily slowing nerve signals and increasing pain tolerance7. It's useful for joint inflammation, acute injuries, and pain following intense exercise8.

You can also alternate hot and cold therapy to stimulate circulation, stop inflammation, and numb pain. This is known as contrast therapy.

When to use heat and cold therapy to relieve pain?

Let's understand the many heat therapy benefits by exploring the issues that may improve as a result of heat and cold therapy.

Uses of Hot & Cold Therapy

Arthritis and joint pain

Joint pain and inflammation respond well to both hot and cold therapies. Our microwave body wraps and products can be heated or frozen. We also sell adjustable aromatherapy packs with flexible gel beads that mould to your joints.

Using gel packs for heat therapy: Place the gel pack in the microwave for 1-3 minutes before strapping it to your knee or elbow for 20-30 minutes. You can reapply this several times per day.

For cold therapy: Place the gel pack in the freezer for 1-2 hours, then strap it to your painful joint for 15 minutes at a time. Place a cloth on your skin before using the cold pack to avoid freezer burn. Take a two-hour break before applying cold therapy again.

Backache and neck ache

Superficial heat therapy for back pain and neck aches works by relieving muscular knots and improving flexibility. Hot water bottles, microwavable gel packs, body wraps, and soft toys are easy to heat and apply to achy muscles.

We also have microwavable warmers shaped for your neck that are effective for wearing across your shoulders to relieve neck and shoulder pain. Place it in the microwave for 1-3 minutes. Let it cool for 30 seconds before holding it against your back, neck, or painful muscle for 20-30 minutes. It's best to do this while lying down and relaxing.

Heat therapy for back pain works well in conjunction with essential oils. Peppermint, lavender, eucalyptus oil, and rosemary essential oils are some of the most effective aromatherapy oils for pain and tension. For an anti-inflammatory blend, combine 2 drops of lavender oil, 2 drops of peppermint oil, and 2 drops of eucalyptus oil. Add this to your microwavable wheat bag or body wrap for topical and aromatic pain-relief benefits. You can reheat and reapply as needed.

Pregnancy aches, stomach cramps, and period pain

When heated, hot water bottles, microwavable bean bags, and body wraps relax muscles in your abdomen and alleviate cramps and period pain9. Heat therapy also works wonders for muscle, joint, and ligament pain during pregnancy.

Rest a hot water bottle or microwave body warmer on your abdomen for 20-30 minutes while relaxing. You can put a few drops of your favourite calming or anti-inflammatory essential oil onto the heated bag for extra heat therapy benefits. However, make sure the bag or hot water bottle has a cover on before it touches your skin.

Nasal and sinus congestion

Allergies, nasal congestion, and sinus infections create pressure, which may cause headaches and facial pain. Heat therapy can open the sinuses and relieve pain. In addition, many aromatherapy eye masks and heat packs are infused with anti-inflammatory and decongestant essential oils.

Place an eye mask, gel headband, or wheat bag in the microwave for 1-2 minutes before gently holding it to your sinus area for 10-15 minutes.

Migraines and headaches

Cold therapy can help eye strain, headaches, and migraines by constricting blood vessels and lowering inflammation.

We suggest freezing a migraine-relief headband or eye mask for 1-2 hours before holding it to your forehead, eyes and temples for 15 minutes. These are infused with lavender, mandarin, and geranium essential oils to soothe your mind and body.

Diabetic neuropathy

Diabetic neuropathy – nerve damage – often causes painful, tingling, cold feet. Our microwavable foot warmers and booties keep your feet warm and reduce discomfort to your extremities. They have removable pouches filled with dried rice or wheat that can be heated. Remove the pouches from the slippers and microwave them for 2 minutes before putting them back in the slippers and sliding them on your feet. They can keep your feet warm for up to an hour!

Acute injuries

Cold therapy is the best treatment for acute soft-tissue injuries – such as muscle or tendon sprains, bruises, and inflammation – in the first 72 hours. It constricts your blood vessels, slowing down tissue damage and numbing the area.

Place a wheat bag or body wrap in the freezer for an hour or two before holding it to the affected area for 15-20 minutes. It's best to apply cold therapy immediately after the injury has occurred.

Ongoing injuries

When the initial trauma of an injury has resolved, it's time to apply heat therapy. The heat helps with lingering injuries by increasing blood flow to the area and releasing tension.

Using a hot water bottle, microwaveable body wrap, or wheat bag is useful before you engage in stretching and rehab exercises.

Stress

Heat promotes relaxation by stimulating blood flow and improving circulation around the body. It also has the effect of making you more comfortable in your surroundings. Heat products such as a hot water bottle or microwave body warmer perhaps with a touch of essential oils are all you typically need.

Conclusion

Heat and cold therapy could be just the thing you are looking for to find relief from aches and pains and get back to living your life to the fullest!
