In daily life, when symptoms such as joint pain, muscle spasms or menstrual cramps occur, we usually use tools such as hot towels, hot water bottles, or self-heating patches to relieve pain in specific areas by releasing heat.
This is known as a heat therapy — a treatment that provides warm stimulation and comfort by applying a heat source directly to the surface of the body. It is a common type of physical therapy that produces therapeutic effects by increasing tissue temperature and promoting blood circulation.
II. Mechanism and physiological effects of Heat Therapy
2.1 How do Heat Therapy work by increasing blood flow and promoting muscle relaxation?
2.1.1 Increases blood flow:
Heat Therapy cause peripheral blood vessels to dilate, which is called vasodilation. When the heat source comes into contact with the skin, the increase in temperature causes the blood vessels to dilate, increasing the amount of blood flowing to the area where the heat is compressed.
Vasodilation improves blood circulation, increases the supply of oxygen and nutrients, and helps eliminate metabolites. This helps to facilitate the tissue repair and rehabilitation process.
2.1.2 Promotes muscle relaxation:
Heat Therapy can promote muscle relaxation and reduce muscle tension and cramping. The application of heat sources can increase the temperature of tissues, which in turn affects the activity of nerve endings.
Warm stimulation inhibits muscle contraction by affecting nerve transmission and regulating muscle tone. This helps to reduce muscle spasms and improve muscle flexibility and range of motion.
2.2 What are the effects of Heat Therapy on blood circulation, pain perception, and tissue repair?
2.2.1 Blood circulation: Heat Therapy can dilate blood vessels and promote blood circulation. When local tissues are warmed, blood vessels dilate, increasing blood flow to the area, increasing the supply of oxygen and nutrients. This helps to speed up the removal of waste and promote tissue repair and rehabilitation.
2.2.2 Pain perception: Heat Therapy can reduce pain perception. By stimulating heat-sensitive nerve endings, Heat Therapy can inhibit the activity of neurons that transmit pain signals. In addition, Heat Therapy can also promote the release of endogenous pain-relieving substances, such as endorphins, which can reduce the sensation of pain.
2.2.3 Tissue repair: Heat Therapy can promote tissue repair and healing. Heat Therapy can increase local blood flow, providing enough oxygen and nutrients to support cell metabolism and tissue repair processes. In addition, Heat Therapy can also promote collagen production, accelerate wound healing and tissue regeneration.
2.3. The relaxing effect of Heat Therapy on the nervous system
2.3.1 Reduce nerve impulses: Heat Therapy can reduce the transmission speed of nerve impulses, thereby reducing the excitability of the nervous system. This reduces the activity of neurons and makes the nervous system more relaxed.
2.3.2 Relax muscles: Heat Therapy can promote muscle relaxation. When muscles are warmed, the increase in temperature can promote blood circulation, increase the supply of oxygen and nutrients, and accelerate the removal of waste products. This can reduce muscle tension and spasms, which can help relax tense muscles.
2.3.3 Pain relief: Heat Therapy can reduce the perception of pain by the nervous system. By stimulating heat-sensitive nerve endings, Heat Therapy can inhibit the activity of neurons that transmit pain signals. This can reduce the perception of pain and make the nervous system more relaxed.
2.3.4 Relaxing mental state: Heat Therapy can also promote physical and mental relaxation by providing a feeling of warmth and comfort. The feeling of warmth can trigger the body to release endogenous relaxation responses, such as endorphins and dopamine, which can help relieve anxiety and stress.
III. Application areas of Heat Therapy
