Summary
Red Light Therapy uses red and near-infrared wavelengths to gently support natural cellular processes. Full-body sessions are non-invasive, comfortable, and designed to support overall wellness routines. In this guide, you’ll learn how red light therapy works, what to expect in a session, how to prepare, and how full-body beds differ from at-home LED masks and devices across Ireland.
At The Tanning Shop Ireland, we’re often asked: “how does red light therapy work?” This guide explains the science in simple terms, red light therapy benefits, what to expect in a session, and how our full-body red light beds compare with other LED devices, helping you understand how red light can support your routine.
What is Red Light Therapy? A Quick Overview
Red Light Therapy, also called Photobiomodulation (PBM) or low-level light therapy (LLLT), is a non-invasive treatment that uses red and near-infrared light to promote overall health and wellness. Many people incorporate red light into their wellness routines for relaxation, skin care, post-exercise recovery, and general well-being.

How Does It Work? Red Light Therapy Science Explained
Here’s an overview of how the treatment works:
- Red light and near infrared light penetrate deep into the body to stimulate mitochondria in your cells.
- These wavelengths of light cause your mitochondria to produce more energy in the form of ATP (adenosine triphosphate).
- ATP provides the fuel that each cell needs to carry out all its functions, including regeneration and healing.

What to Expect from Red Light Therapy at The Tanning Shop Ireland
Do you want to experience the red light therapy bed benefits for yourself? Here’s what a typical red light session at The Tanning Shop looks like.
On arrival, a trained specialist will guide you to your private room and begin your consultation.
Once ready for your treatment, you’ll be left to undress, put on your free eye protection, and lie down on the bed.
Relax for 15 minutes as the red light soothes and energises your body and mind.
After the session, carefully step out of the bed before dressing.

What Does Red Light Therapy Feel Like?
Most people feel a gentle warmth throughout the session. This is entirely normal, and the beds will not emit intense heat or burn the skin. Many clients note the gentle heat as one of the infrared bed benefits, as it helps them to relax and unwind.
How to Get the Most Out of Your Red Light Session
Preparation, aftercare, and consistency are key to ensuring the best red light therapy results.

FAQs
What Exactly Does Photobiomodulation Mean?
Photobiomodulation is the scientific term for how red and near-infrared light interacts with your cells. When this light is absorbed, it can help support natural cellular energy processes. Non-invasive, gentle, and widely used, this method is effective in full-body red light therapy.
Does Red Light Therapy Really Work?
Studies show that red light therapy is effective in supporting skin health, relieving inflammation, and accelerating healing. As red light is a relatively new treatment, further research is needed to establish broader wellness benefits.
Our clients at The Tanning Shop note improvements to complexion, mood, pain relief, and healing, and enjoy the relaxing experience in our full-body beds.
How Many Red Light Sessions Do Most First-Time Clients Book?
Many first-time clients start with a 10-minute taster session to experience what red light feels like. Multi-session packages are available for those who want regular treatments as part of their routine. Your consultant can advise on a schedule based on your goals and preferences.
