How Heat Therapy Can Improve Circulation and Reduce Inflammation


Heat therapy, or thermotherapy, is a natural way to improve circulation and reduce inflammation. It’s been used for centuries to treat many ailments and injuries.

Let’s take a look at how this therapy works and the advantages it can bring.

What is Heat Therapy?

Heat therapy is a form of treatment using heat or laser-generated waves on body parts. It helps reduce inflammation, increase flexibility, relax muscles, heal wounds, reduce pain, and improve circulation.

Sources of heat fall into two categories: deep heat and superficial heat. Deep heat penetrates skin and muscles to treat chronic pain like arthritis or joint stiffness. Superficial heat helps with muscle pain or tightness and boosts blood flow.

Popular sources of heat include:

  • Paraffin wax dips and hot water bottles
  • Infrared saunas, heating pads/blankets, and jade stone mats work for deep muscle tension and chemotherapy-related nausea.
  • Light therapy can also speed up healing.

Benefits of Heat Therapy

Heat therapy, or thermotherapy, is the use of heat to ease pain, increase blood flow and reduce inflammation. A hot water bottle, heating pads, compress packs and heated pillows are all ways it can be applied.

It works by deeply heating the muscles, ligaments and tendons around a joint. This allows more oxygen to the area, aiding in quicker healing and better flexibility. Heat therapy may also lessen stress levels, providing a calming sensation to inflamed areas caused by muscle spasms. Reducing inflammation helps ease pain and speeds up healing from injuries such as strains, bruises or soft tissue injuries.

Combining heat therapy with other therapies like massage or cold therapy can further the benefits. These therapies have distinct advantages that help the healing process.

The advantages of heat therapy include:

  • Relaxation of underlying muscles due to improved circulation
  • Reduced muscle spasm leading to better flexibility
  • Reduction in pain from inflammation or injuries due to increased movement
  • Stress relief and improved wellbeing
  • Faster recovery time for injuries.

How Heat Therapy Works

Heat therapy is a popular remedy for improving circulation, lessening inflammation, and calming muscle tension. Heat can be applied to the skin directly, or through a heating pad, hot water bottle, or moist towel. Heat is usually combined with a massage to create an even greater calming effect.

In this article, let’s discover how heat therapy works and the advantages of using this natural form of healing.

Increase Blood Flow

Heat therapy is a popular, easy-to-use way to boost circulation and reduce inflammation. It works by raising the body’s temperature, which increases blood flow to target spots. The extra blood brings oxygen and nutrients, aiding healing. Heat therapy can be applied in several ways.

Applying Heat Therapy:

  • One common approach is with a heating pad or wrap, which can go around a sore joint or tense muscle. Heating pads come in electric or microwavable versions, plus various sizes for different body parts. Hot water bottles are easy to use at home, as are warm baths with Epsom salt to soothe muscle aches after exercise. Always check the temperature before using heat to make sure it’s comfortable and your skin can handle it.

Benefits of Heat Therapy:

  • As well as improving circulation, heat therapy helps ease muscle tension and soreness. It also reduces inflammation from sprain, strain and overuse injuries. If chronic pain is a problem, ongoing treatment might be recommended but often one application of heat is enough.

Reduce Muscle Tension

Heat therapy is popular for reducing muscle tension and improving circulation. It works by increasing blood flow. This helps to relax tight muscles, easing pain, and helping them to move more easily. Improved circulation brings oxygen to the muscles, which speeds up healing.

Heat therapy is used in therapeutic massage to relax the mind and body. It offers relief from headaches caused by facial muscle tension. Athletes use heat therapy to loosen stiff muscles before workouts and help with recovery afterwards. Hot baths reduce inflammation, soreness and fatigue associated with exercise, without disturbing training.

Reduce Inflammation

Heat therapy is a common way to reduce inflammation and improve circulation. By using a heating pad or other types of heat, blood vessels in the area expand and increase blood flow. This can help reduce swelling, muscle pain, and stiffness. It also flushes away extra fluid and helps white blood cells fight infection.

Heat therapy can also help heal injured muscles, tendons, ligaments, sprains, nerve issues, bursitis, fibromyalgia pain and arthritis pain.

Types of Heat Therapy

Heat therapy is a great solution for reducing inflammation, improving circulation, and easing tight muscles. There are many forms of heat therapy available. These include:

  • Moist heat
  • Dry heat
  • Infrared light
  • Ultrasound
  • Electric stimulation

All bring their own advantages and treat different issues. Let’s take a closer look at each type!

Hot Water Therapy

Hot water therapy is a form of heat therapy to increase blood flow and reduce inflammation. Submerge your body in warm/hot water to calm muscles, relieve stress and promote healing. The temperature should be 103-105°F (39.5-40 C). Adding Epsom salt may aid in relaxation and reduce soreness through enhanced magnesium absorption.

However, stay hydrated while using hot water therapy as dehydration causes more pain. Consult a doctor before trying hot water immersion as some medical conditions need to be considered.

Heat Pads

Heat pads are a popular form of heat therapy. They come in different materials and sizes, such as gel packs, wheat bags, hot water bottles, rice bags, and electric heating pads.

Apply the heat pad to the area with caution. It can burn if left too long or set at a high temperature. Test it on a small area of skin before using.

Heat pads can help reduce minor aches, increase circulation, reduce inflammation, and relax tight muscles.

Infrared Therapy

Infrared therapy is gaining popularity due to its potential benefits. It uses infrared radiation to stimulate the body’s cells and increase blood flow and nutrients. This helps reduce joint stiffness, inflammation, pain, and muscle spasms.

Infrared radiation is found naturally in our environment. Heat is applied directly to the body through thermal devices like lamps or electric pads that emit infrared light. This light penetrates the body’s soft tissue layers, producing a warming response to targeted areas. Electrical currents may also be used to further increase muscle stimulation.

Infrared therapy has a variety of uses for treating physical ailments. Heat can help with faster relief than other forms of physical therapy. It can

  • buffer pain signals
  • relax tight muscles
  • speed up injury healing time
  • ease back soreness

More research is needed, but this treatment is becoming popular for managing chronic or acute pain without medication or surgery.

Safety Considerations

Heat therapy can be beneficial, however it can also be dangerous. Before use, assess any medical conditions and decide if it is safe. Also, take precautions to stop potential burns or injuries. Consider these safety considerations:

  • Check for medical conditions
  • Assess safety
  • Reduce risks

Avoid Burns

Heat therapy can be a great way to manage circulation and reduce inflammation. But, beware – burns can happen if skin is exposed to extreme heat for too long. To avoid this, use moist and dry heat properly and in small doses.

When using moist heat, like a hot pack, wrap it in cloth first. Don’t let the temperature get above 113°F (45°C). With dry heat, like an electric heating pad, stick to the manufacturer instructions. Temperature should not exceed 149°F (65°C). If treating larger parts of the body, be extra careful – higher temperatures are possible. Cover only a third of the body with a heating pad at a time.

People with diabetes or circulatory problems should take extra precautions when using heat therapy.

Monitor Temperature

When using heat therapy, it’s important to keep an eye on the temperature. Too much heat can cause irritation and burns. Use a thermometer if you’re using hot water or compresses. If you’re using an electric blanket or heating pad, set it low and stay nearby. Make sure the areas being treated with heat remain uncovered, so the body heat can increase evenly. Monitor how your skin reacts to the heat in different areas. If you feel faint or dizzy, immediately remove the heat source. Allow time for your body temperature to return to normal.

Pay attention in a sauna; never exceed 15 minutes due to dehydration risks.

Seek Professional Advice

Before using heat therapy, it is vital to get professional advice from a doctor or qualified health expert. It can be hazardous with potential complications like burns. Those with conditions such as diabetes, hypertension, or heart disease should talk to their healthcare provider prior to treatment.

The environment for heat treatment is also essential. Ensure there are no flammable objects or furniture. Moisture could increase the risk of shock or electric current, so make sure the area is dry. It should be done in the presence of a caregiver or trained health professional. Do not use without proper instructions.


Heat therapy is gaining traction. People are recognizing its potential to help with blood flow, reduce inflammation, soothe muscles, improve joint mobility, calm the mind & body, and lower stress.

One must consider the intensity of the treatment to get the most out of it. It’s vital to consult a medical professional before taking heat therapy because it can cause harm if done wrong.
