Red light therapy and mood: can light support your mental wellness?
Updated: Jul 17
Low mood, mental fog and burnout can quietly drain your energy, focus and motivation. Alongside the support of a doctor or therapist, many people look for gentle, natural ways to feel more like themselves. One approach getting attention is photobiomodulation — using specific wavelengths of red and near-infrared light to support the body at a cellular level. Here is an honest look at what it can, and cannot, do for your mood.
What is photobiomodulation?
Photobiomodulation (PBM) — the science behind red light therapy — uses red and near-infrared light, roughly between 600 and 1,000 nanometres, to gently stimulate your cells. It is different from the bright ‘daylight lamps’ used for the winter blues, which work through the eyes to influence your body clock. PBM works on the tissue itself: the light is absorbed by your cells and helps them produce energy more efficiently.
How light may support your mood
Research into light and mental wellness is still young, but the early signals are encouraging. Scientists are exploring several ways red and near-infrared light may help:
More cellular energy — light supports the mitochondria in your cells, which may help brain cells work with more energy and less fatigue.
Calmer inflammation — chronic, low-grade inflammation is linked to low mood, and light appears to have a soothing, anti-inflammatory effect.
Better blood flow — improved circulation brings more oxygen and nutrients to the areas that help regulate how you feel.
Deeper rest — many people notice they sleep more easily, which has a knock-on effect on mood, focus and resilience.
It is important to be honest here: this is an emerging field. Recent research reviews suggest PBM may reduce symptoms of low mood as a complementary approach, but it is not a proven cure and results vary from person to person. Think of it as support for your overall wellbeing, not a replacement for medical care.
Full-body light at Light Angel
There are two main ways to use light for mental wellness. Some devices target the head directly (transcranial), while full-body treatment bathes your whole system in red and near-infrared light. At Light Angel Amsterdam, Virginie works with high-powered, full-body LED panels — supporting your circulation, calming inflammation and helping your cells recharge across your whole body, not just one spot.
What a session feels like
A session is completely passive and deeply relaxing. You rest while the light does the work — most people feel a gentle warmth, or nothing at all. There is no heat damage, no discomfort and no recovery time, so you can head straight back into your day. Sessions usually last around 20 to 40 minutes, and many clients describe the experience as calming, almost meditative.
Is it safe?
Red and near-infrared light therapy is non-invasive and well tolerated. It does not use UV, so there is none of the skin damage linked to sunbeds. The most common minor effects — a temporary warm feeling or mild eye sensitivity — are easily avoided with proper eye protection. Most importantly: PBM is a complementary therapy, not a substitute for professional care. If you are working with a doctor or therapist, please keep that support, and talk to them before making any changes to your treatment.
Frequently asked questions
Can light therapy replace my antidepressant or therapy?
No. PBM is meant to work alongside professional care, not replace it. Never stop or change prescribed treatment without talking to your doctor first.
How is this different from a daylight lamp?
A daylight lamp uses bright, broad-spectrum light through your eyes to influence your body clock. PBM uses specific red and near-infrared wavelengths that are absorbed by your tissue to support your cells — a different, deeper mechanism.
How soon might I notice a difference?
It varies. Some people notice better sleep or a lighter feeling within the first few sessions; for others it builds gradually over several weeks of consistent use. Patience and consistency matter.
Who is it best suited for?
People dealing with low mood, stress, burnout or poor sleep who want a gentle, drug-free way to support their wellbeing — especially alongside other healthy habits. If you have a diagnosed condition, use it as a complement to your existing care.
