What is Infrared Therapy? 

Infrared therapy involves the use of infrared wavelengths of light, which are longer than visible light but shorter than radio waves. When infrared light is absorbed by the body, it causes the molecules in the tissues to vibrate, generating heat. The heat, in turn, penetrates deep into the tissues, including muscles, joints, and organs. 


This deep heat can have several beneficial effects on the body. It can help relax tight muscles, relieve pain and inflammation, improve blood circulation, and boost the delivery of oxygen and nutrients to tissues. 


What is Red Light therapy? 

Red light therapy, uses specific wavelengths of red or near-infrared light. When red or near-infrared light is absorbed by cells in the body, it can trigger various cellular mechanisms. 


Red light therapy has shown potential benefits for skin health. It can also help reduce pain and inflammation, accelerate wound healing, and promote overall cell rejuvenation.

What are the benefits of Infrared and Red Light therapy? 

Infrared and red light therapy offer a range of potential benefits for various health conditions. Some of the most common benefits include: 


Pain relief 

Infrared therapy can help alleviate muscle and joint pain by increasing blood flow, reducing inflammation, and promoting relaxation. Red light therapy can also reduce pain by stimulating the production of pain-relieving substances in the body. 

Improved skin health 

Red light therapy can stimulate collagen production, which can improve skin elasticity, reduce wrinkles and fine lines, and enhance overall skin tone and texture. It may also help with acne and other skin conditions by reducing inflammation and promoting healing. 

Repairing properties 

Both infrared and red light therapy have been shown to promote tissue repair, increase blood flow to the area, and stimulate the growth of new cells. 



Light therapy, including red light therapy, has been found to have positive effects on mood and energy levels. It can help regulate circadian rhythm, improve sleep quality, and reduce symptoms of seasonal affective disorder (SAD) and depression. 

Improved Range of Motion 

Infrared and red light therapy may aid in muscle recovery, reduce exercise-induced muscle damage, and improve athletic performance by enhancing circulation and reducing inflammation. 



Red light therapy can stimulate cellular metabolism and increase the production of adenosine triphosphate (ATP), which provides energy to cells. This can have various positive effects on cellular function and overall health. 


It's important to note that the effectiveness of these benefits may vary depending on the individual and their needs. It is advisable to consult with a healthcare professional for guidance on the appropriate use of infrared and red light therapy for your specific needs. 


Is Infrared better than regular heat? 

Infrared therapy and regular heat can provide different benefits and have different mechanisms of action. Whether one is better than the other depends on the specific condition or goal being targeted. 


Infrared therapy uses specific wavelengths of light to penetrate the skin and heat the body directly. This deep penetration allows for targeted heating of tissues, promoting various therapeutic effects such as increased blood circulation, pain relief, and tissue repair. 


Regular heat therapy, on the other hand, typically involves using sources like hot water, heating pads, or hot packs to warm the body. This external heat primarily warms the surface of the skin and may not penetrate as deeply as infrared therapy. 


The choice between infrared therapy and regular heat depends on the desired outcome and individual preference. Infrared therapy may be more suitable for targeting deep tissue pain, promoting blood circulation, and stimulating healing. Regular heat therapy may be more convenient and accessible for general relaxation and mild discomfort. 

Luckily for Jacuzzi® Hot Tub users, our JL-XR seat combines both of these therapies as it allows hydrotherapy and Infrared therapy to work hand in hand to create a rejuvenating experience within the steamy haven of your hot tub.


It's important to note that both therapies have their merits, and consulting with a healthcare professional or therapist can help determine the most appropriate option for your specific needs.

Goes beyond just skin deep… Infrared and Red Light therapy is projected by the red lamps. This therapeutic approach enhances blood circulation, bringing in new blood accompanied by white blood cells, thereby promoting the body's innate healing potential. This process also purges impurities and initiates the healing mechanism with freshly oxygenated blood. 


The red light focuses on the surface, aiding in skin rejuvenation, inflammation reduction, and an overall improvement in skin appearance and texture. In contrast, the infrared aspect delves deeper into joints, muscles, and soft tissues, providing relief from pain and restoring range of motion.
