# The Benefits of High Frequency Heat Therapy

Studies show that passive heat therapy induces favorable health-promoting adaptations in skeletal muscle. For example, a 4 week protocol of passive heating improved knee extensor maximal isometric torque in young healthy subjects.

 Local heat therapy improves many aspects of human health and performance. This includes cardiovascular, metabolic, and mental health.

 

## Pain Reduction

 When you apply heat to the skin’s surface, it activates temperature-sensitive nerve endings and blocks pain signals from travelling up the spinal cord. Heat also increases blood flow and delivery of oxygen and nutrients to muscles and tendons, which flushes away chemical irritants that may be contributing to your pain.

 [![Rejuvenate your whole body & balance your health without medications - now remotely!](https://alsuprun.com/blog/wp-content/uploads/BioresonanceTopAd.png)](https://www.bioresonance.rent) Superficial heat modalities include hot packs, heating pads, infrared light therapy and fluidotherapy. These modalities transfer energy via conduction (direct contact), convection (friction of heated liquid or gas flowing over the surface of the body) and conversion (changing one form of energy into another; example, electricity to thermal energy).

 Low frequency electrical stimulation (TENS, TMS) and pulsed shortwave diathermy are high-frequency modalities that produce deep thermal heat by passing an electric current through a capacitor and inducer cable electrodes. These modalities deliver intense heat to the injured tissues without burning your skin. These modalities can treat chronic pain in addition to musculoskeletal injuries, including fibromyalgia, arthritis, tendinitis and soft tissue damage.

 Both HIPER-500(r) and SonoStim (brand name of an experimental new device) were used in this study to deliver a new type of high-frequency deep heat treatment. The researchers confirmed the exact location of each patient’s shoulder lesion using ultrasound imaging before deciding which modality to use on that session. During each session, the researchers lowered either the power output or the contact area between the small ceramic transducers and the skin, depending on how much heat the patients could tolerate.

The results showed that both HIPER-500(r) and the traditional ultrasound device SonoStim produced similar improvement on the VAS, UCLA, SPADI and Constant scores for shoulder pain.

 Understanding the differences between these three different types of electrotherapy can help you ask more informed questions when discussing what modality your physiotherapist or rehabilitation specialist will choose to use on your next treatment visit. Each modality has its own strengths and weaknesses, depending on the condition being treated. For example, a superficial knee ligament probably responds well to TENS while a deeper hip joint capsule needs IFT or PSWT.

 

## Muscle Relaxation

 When muscle tissue becomes stiff or tight, it can be difficult for the body to relax those muscles. [High frequency heat therapy](https://alsuprun.com/) encourages the muscle to relax by increasing blood flow. This helps improve circulation, delivers oxygen to the injured area, and reduces pain by removing the buildup of metabolic byproducts like lactic acid. When muscle tissue is relaxed, pain signals are decreased, and the muscles can return to their normal resting tone.

 When a patient experiences soreness after exercise, a massage therapist may apply a heating pad to the affected area. Alternatively, a warm bath or shower can help ease the pain by warming up the tissues and helping them stretch more easily. This is because the warming effects of heat increase elasticity and flexibility in muscle tissue, which allows for safer stretching and increases range of motion.

 In addition, a recent study compared the effectiveness of an advanced therapeutic deep heating device, called the HIPER-500(r), to ultrasound as an established method for treating shoulder pain and dysfunction. The results showed that the HIPER-500(r) provided comparable pain relief, increased range of motion, and improved function to ultrasound. This study shows that the HIPER-500(r) is an effective alternative treatment for shoulder pain and discomfort.

 One of the reasons why ice can be counterproductive for some patients is that it causes the muscles and surrounding tissues to guard against further damage. Unless the initial injury has significant bruising, ice should be avoided for muscle injuries and instead gentle heat should be used.

 [![](https://alsuprun.com/blog/wp-content/uploads/RadionicMerch.png)](https://alsuprun.com/merch.html) The reason why heat is so much better for chronic stiffness, day-to-day soreness, and nagging muscle aches is that it triggers vasodilation in the targeted tissues, opening up the blood vessels to allow a new supply of oxygen and nutrients to reach the injured tissue. This helps to flush away the metabolic byproducts that accumulate in tight, overworked muscles, and it helps accelerate muscle repair.

 The patented heat cell technology in the ThermaCare Muscle Pain Therapy HeatWraps works to unlock tight, sore, and stiff muscles at the source by delivering long-lasting, drug-free pain relief with every use. The wraps are easy to use, portable, and thin enough to wear discreetly under clothing.

 

## Stress Reduction

 One of the most beneficial effects of passive heat therapies, especially Finnish sauna baths, is stress reduction. The warm environment activates the parasympathetic nervous system that supports rest and recovery, allowing the body to shift out of stress mode into a more calm internal state. This relaxation is often felt as a decrease in heart rate, deeper breathing, muscle tension release and feelings of calm. The benefits of these changes are cumulative and may be sustained for longer periods of time when sauna use is repeated on a regular basis.

 In fact, studies have shown that those who regularly use saunas on a daily or weekly basis have lower rates of high blood pressure, heart disease and other conditions [1, 2, 3].

 Another way in which heat therapy can relieve stress is by activating the endocrine system. The physiology behind this is that when the body is exposed to thermal energy, the adrenal gland releases hormones to help control the fight or flight response, reducing stress and anxiety. In fact, a small study that randomly assigned 28 mildly depressed inpatients to receive either far-infrared sauna sessions or usual care over four weeks showed that the patients who received the sauna experienced improved mental health symptoms compared with those who did not.

 The same calming effect of heat therapy has been observed in individuals with chronic heart failure. A study that analyzed 64 eligible trials found that patients with heart failure who used traditional or infrared saunas regularly (three to seven times per week for 30 to 90 minutes) experienced improvements in NYHA classification, systolic and diastolic blood pressure, left ventricular ejection fraction, cardiac geometry and levels of natriuretic peptides and noradrenaline.

 Adding to these benefits, high-frequency heat therapy is an excellent tool for pain management and is also helpful for those with other chronic or inflammatory diseases of the muscles, joints and spine. During the course of a treatment session, patients are able to communicate with their therapist about the temperature and intensity of the heat, so that the optimum level of comfort can be achieved. The therapist can adjust the yield or contact area of the small ceramic transducer in order to optimize the treatment intensity.

 

## Pain Management

 Electrotherapy is a common tool in physiotherapists’ and rehabilitation specialists’ arsenal to manage pain, support muscle recovery, and promote healing. Different modalities use different frequencies to stimulate your nerves and muscles. Understanding what the frequencies do will help you have more informed conversations with your practitioner about the benefits and limitations of each type of electrotherapy.

 The frequency of electrical stimulation is measured in Hertz, or the number of cycles an electric current makes per second. Your pain-sensing nerves respond to one range of frequencies, while the motor nerves that fire your muscles respond to another. Your deeper tissues and cells respond to yet a third.

 Low-frequency electrical currents, like TENS (transcutaneous electrical nerve stimulation), generate discrete, individually felt pulses that your body interprets as signals. These can block a pain signal, contract a weak muscle, or reduce swelling in a stubborn injury. The frequency of the pulses is important to understand, because different tissues have different responses to varying levels of electricity.

 Medium-frequency electrical stimulation, like EMS (electrical muscle stimulation), generates waveforms that deliver sustained, low-level stimulation to your muscles. These waves can increase the blood flow in your muscles, helping them relax and increase their elasticity. They can also trigger a reflex, called the stretch-reflex, that increases the strength and length of your muscles.

 High-frequency electrical stimulation, like HIPER-500 (high-frequency therapeutic deep heat therapy), combines the capacitive electric transfer and resistive electric transfer (RET) techniques. This helps maximize the effect of heat on your muscle and tissue while minimizing unwanted side effects such as light burns. This device uses a frequency of 4.4 MHz to penetrate deeper into your muscles and tissues. The ceramic transducers that contact your skin are insulated to further reduce the risk of injury and discomfort.

 Research on HIPER-500 has shown that it provides similar benefits to ultrasound for pain relief and function recovery. It may be a useful modality to treat shoulder pain and improve physical performance. It is a great option for patients who want to avoid the potential complications of surgery. However, it is always recommended that you consult with a medical professional to see if it is the right treatment for you.
