Infrared and Red Light technology has gained popularity in wellness products, including Jacuzzi hot tubs. These these lights enhance relaxation, improve circulation, and promote healing. But does this technology actually work when integrated into a hot tub? This post explores the science behind infrared and red light therapy, how it applies within a hot tub, and what users can realistically expect.

Understanding Infrared and Red Light Technology
Infrared and Red Light therapy use specific wavelengths of light to penetrate the skin and underlying tissues. Infrared light typically ranges from 700 nm to 1 mm in wavelength, invisible to the naked eye but felt as heat. Red light has shorter wavelengths, around 620 to 750 nm, visible as a deep red glow. Jacuzzi hot tubs use their patented design which uses full-spectrum Infrared 850nm and 660nm within their Red Light to penetrate muscle and tissue.
These lights stimulate cellular activity by increasing mitochondrial function, which helps cells produce more energy. This process can lead to:
Improved blood flow
Reduced inflammation
Enhanced tissue repair
Pain relief
Jacuzzi use Infrared and Red Light within their saunas and spas for these benefits. The question is whether these effects translate effectively when the technology is embedded in a hot tub environment.

How Infrared and Red Light Work in Hot Tubs
Hot tubs already provide heat therapy through warm water, which relaxes muscles and improves circulation. Infrared and Red Light add another layer of benefits by targeting cells directly with light energy.
Infrared Light in Hot Tubs
Infrared in hot tubs emit radiant heat that penetrates deeper than traditional water heat. This can warm muscles and joints more effectively without raising the water temperature excessively. Users may feel soothing warmth that reaches tissues beneath the skin surface.
Red Light in Hot Tubs
Red light therapy in an hot tub is used to stimulate skin cells and promote healing. The visible red glow can also create a calming ambiance, enhancing the overall relaxation experience.
Combined Effects
Together, Infrared and Red Light therapy can complement the hot tub’s heat and massage jets. The combined effect may:
Increase relaxation
Reduce muscle soreness
Support skin health
Improve circulation
However, the intensity and exposure time of the lights in the hot tub are usually lower than in dedicated therapy devices.

What Research Says About Effectiveness
Scientific studies on infrared and Red Light therapy show promising results for pain relief, wound healing, and inflammation reduction. For example, research published in the Journal of Clinical and Aesthetic Dermatology found Red Light therapy improved skin texture and reduced wrinkles after consistent use. User to user may vary.
Infrared therapy has been shown to help with muscle recovery and joint pain in athletes. A study in Photomedicine and Laser Surgery reported reduced pain and stiffness in patients with osteoarthritis after Infrared treatment.
However, most studies use controlled devices with specific wavelengths and exposure times.
Real User Experiences
Many hot tub owners report feeling more relaxed and less sore after sessions with Infrared and Red Light features. Some noted improved sleep quality and reduced joint stiffness. However, others say the effects are subtle and not a replacement for dedicated light therapy treatments.

Final Thoughts on Infrared and Red Light in Hot Tubs
Infrared and Red Light technology within Jacuzzi hot tubs offers a promising way to enhance the traditional benefits of warm water therapy.
The rejuvenating powers of Infrared and Red Light therapy work together deep beneath the skins surface to relieve pain, improve range of motion, and help you reach a state of mindfulness.
Low back pain is the leading cause of disability worldwide, so Jacuzzi strategically placed IR and Red Light therapy to target deep tissue within the lumbar region of the lower back.
Users should view these features as a helpful addition rather than a cure-all. Combining light therapy with regular hot tub use, healthy lifestyle choices, and professional treatments can provide the best results.
