All About Infrared+Red Light Therapy

DID YOU KNOW? Jacuzzi® is the first and only brand to offer Infrared+Red Light therapy across a range of wellness products, from Infrared Saunas to Hot Tubs and Swim Spas.

You've probably been hearing a lot of buzz about Infrared and Red Light technologies—from clips of influencers trying out glowing face masks and wands, to fitness gurus touting the benefits of laying on infrared mats, people are raving about these therapies in health, wellness, and beauty circles. 

But what exactly are Infrared and Red Light Therapy, and why are they becoming such prominent components of modern self-care? Let’s dive in!

What Is Infrared Therapy?
Infrared (IR) therapy uses invisible wavelengths of light—part of the natural spectrum of sunlight—to gently heat the body from within. Unlike traditional heat, which warms the air around you, infrared heat can penetrate beneath the skin, raising your core temperature and promoting deep, soothing warmth without feeling overwhelmingly hot.

Because it penetrates deeper, IR supports muscles, circulation, and cellular activity in a way that typical surface-level modalities don’t.

This “deep heat” is what makes Infrared so effective for muscle relaxation, recovery, circulation, and stress relief, providing the same calming sensation many people associate with a traditional sauna—but with enhanced, targeted benefits for your overall well-being.

How is Infrared Beneficial?
Modern research continues to reveal just how impactful infrared therapy can be for both body and mind. Some of its most widely recognized benefits include:

·    Relieves muscle tension and joint stiffness – Deep infrared warmth helps ease soreness and promote flexibility.
·    Supports detoxification – As your core temperature rises, your body naturally sweats out impurities while improving circulation.
·    Enhances recovery – Infrared helps muscles recover faster after exercise or strain.
·    Improves relaxation and sleep – The gentle, penetrating heat promotes calmness and helps balance the body’s stress response.
·    Boosts overall vitality – Regular use can support cardiovascular health, cellular repair, and immune resilience.

What is Red Light Therapy?
Red Light Therapy is a visible form of light known for supporting skin health, collagen production, and cellular rejuvenation. It uses visible (or near-visible) wavelengths of red and near-infrared light—often referred to as photobiomodulation (PBM)—to stimulate cellular processes.

How is Red Light Therapy Beneficial?
At specific wavelengths, light is absorbed by key cellular components, triggering cellular energy production (ATP), the release of nitric oxide, modulation of reactive oxygen species, and other cell-signaling processes.

These changes support scientifically proven advantages, including:

·    Cellular repair
·    Skin renewal
·    Reduced inflammation
·    Improved circulation

Infrared+Red Light Therapy: A Dynamic Duo
Together, Infrared + Red Light Therapy work synergistically:

·    Infrared delivers deep, therapeutic warmth to muscles and joints.
·    Red Light Therapy supports surface-level healing and revitalization of the skin through cellular regeneration.

This combination provides a comprehensive wellness experience—from the inside out.
