First Things First!  The Scientific Significance of Red Light Therapy

Red light therapy (a simpler name for Photobiomodulation) has gained significant attention in the scientific community due to its non-invasive, drug-free approach to enhancing cellular function and promoting healing.

The therapy is rooted in photobiomodulation (PBM), a process where light at specific wavelengths penetrates the skin and stimulates mitochondria, the energy-producing components of cells.

This boost in cellular energy enhances tissue repair, reduces inflammation, and supports overall cellular health.

Numerous studies have validated its effectiveness for a range of conditions, including wound healing, muscle recovery, pain relief, and skin rejuvenation. Red light therapy is especially valued for its potential to treat chronic conditions like arthritis and improve quality of life without the side effects associated with pharmaceuticals.

Its importance in the world of science lies in its versatility, safety profile, and growing evidence base, making it an increasingly trusted tool in both medical and wellness applications.

As research continues, red light therapy may become a staple in treatments for an even broader range of health issues.

Red light therapy has gained significant popularity for its potential benefits, from improving skin health to boosting muscle recovery and reducing inflammation.

However, determining the ideal duration for daily use can vary depending on your goals and the device you’re using, not to mention the varying philosophies of red light practitioners.

While some sessions normally range from about 5 to 10 minutes, finding the right balance between efficiency and practicality are key to maximizing results without wasting too much time.

In this article, we’ll explore recommended usage times based on different therapeutic needs and how much you can flex your routine without losing the benefits of PBM and all the wonderful properties it offers.

The ideal duration for red light therapy varies based on individual goals, the area being treated, and the power of the device used.



Get to the Point!

If you need answers but don’t want to scour the internet for hours just for some simple information, we’ve got you covered!

For general skin health, 5 to 10 minutes per session (per location), 3 to 5 times a week, is often recommended. If you’re targeting deeper tissues, such as muscles or joints, sessions may last closer to 20 minutes. Beginners should start with shorter sessions, around 1 – 3 minutes, and gradually increase the time as their body adapts.

It’s important to know where you’re using the light, and what device you are operating, as different devices emit varying light intensities.

The frequency of sessions matters—using red light therapy too infrequently might limit the benefits. As a general rule, consistency is more important than longer or more frequent sessions.

By sticking to recommended time frames and allowing your body adequate rest between sessions, you can effectively reap the rewards of red light therapy without any negative effects.


Red Light Therapy (PBM) is Safe

Some sellers of red lights and researchers suggest that there is such a thing as “over-use” of PBM, and while that may be technically true, there is no definitive research showing the negative side-effects of using the light for a longer period.

In fact, lots of anecdotal evidence from users, suggests that many users fall asleep for hours with the light in one location, and rarely is there any skin irritation or any complaint of some sort of side effect of using the light too long.  Will using it too much provide diminishing returns?  No evidence suggests this is the case.

In fact, according to the PBM Foundation, “Photobiomodulation (PBM) uses red and near-infrared light to improve cell function. As this is a natural process helping a natural process, PBM therapy has had no documented side-effects among over 100 million patient treatments since its discovery in 1967.” (https://pbmfoundation.org/testimonials-who-pbm-helps)

The PBM Foundation explains, “Photobiomodulation (PBM) is a non-invasive, FDA cleared, medical technology.” (https://pbmfoundation.org/what-is-pbm/) No side-effects since 1967! Wow, that’s what we call safe!


Exploring Different Goals with Red Light Therapy

NOTE:  Different PBM units have different power outputs, so these usage times are only suggestions and not necessarily scientifically derived prescriptions.

Red light therapy (RLT) and photobiomodulation (PBM) can be tailored to meet various health and wellness goals, each requiring different session lengths and wavelengths

For skin health, including anti-aging and acne reduction, shorter sessions of only a few minutes, 3 to 5 times a week, are suggested as the red light promotes collagen production and skin rejuvenation.

For pain relief and reducing inflammation in muscles or joints, longer sessions of 15 to 20 minutes, focusing on deeper tissues, can help stimulate cellular repair and alleviate discomfort.  

Many users that apply red light therapy for joint pain will very often suggest their best results come by using the therapy no less than once per day.

Red light therapy has also been shown to improve energy levels and mood by enhancing mitochondrial function—sessions of around 10 minutes per day in key locations can give your body an energy boost and improve overall vitality.

Additionally, athletes often use RLT for faster muscle recovery and injury rehabilitation, with sessions of 15 to 20 minutes, 4 to 5 times a week, accelerating tissue healing and reducing post-exercise soreness.

By adjusting the duration and frequency of sessions based on your specific health goals, you can customize red light therapy to maximize its benefits.

*Please remember that while times of 5 or 10 minutes are often suggested, it is only valid with a concentrated light at close proximity. 

So, if you are using a small handheld unit close to your skin, the 5 minutes is good for the area covered.

You’ll have to use it another 5 minutes in another area.  An entire head can be treated in either 50 minutes (10 locations for 5 minutes) or 5 minutes (using a helmet with the equivalent of 10 lights at the same time on different parts of the head).

The farther you move the light from your skin, the more time will be needed to obtain the same benefit as a closer light.  Intensity and power DO MATTER.

Most handheld PBM units are most effective when they are touching the skin rather than many inches away. While it may seem that a light farther from your skin will cover a larger area, the depth of penetration falls off dramatically as the light moves away from the skin, thus increasing application time significantly (to reap the same benefits of a closer light and a shorter application time).


How Long Will it Be Until I Notice an Improvement in my Condition?

Here’s a loaded question with no easy answer, but we can generalize based on feedback from users of PBM therapy.

The range of times to see improvements vary greatly from as little as one treatment of 5 minutes, to many months.

While it’s not unusual for 3 or 4 months to pass before you may feel or notice a difference in your condition, it’s often after 5 or 10 sessions over the course of a few weeks that many people notice an improvement.



Using Red Light Therapy to Treat Seasonal Affective Disorder (SAD)

Red light therapy has also shown promise as a treatment for Seasonal Affective Disorder (SAD), a type of depression that occurs during the darker, colder months when sunlight exposure is limited.

SAD is often linked to disrupted circadian rhythms and lower serotonin levels, both of which can be influenced by light exposure.

Unlike traditional light therapy that uses bright white light, red light therapy works by stimulating the body’s cells at a deeper level, promoting energy production and supporting mood regulation.

Studies suggest that regular exposure to red light, around 10 to 20 minutes per day, can help alleviate the symptoms of SAD by boosting serotonin production, improving sleep patterns, and balancing circadian rhythms.

While RLT doesn’t replace the benefits of natural sunlight, it provides a convenient, safe option to help counteract the lack of daylight and support emotional well-being during winter months.

Incorporating it into a daily routine can be an effective way to manage SAD symptoms and improve overall mental health.



Tips for Maximizing the Benefits of Red Light Therapy

To get the most out of your red light therapy sessions, consistency is the key. Stick to a regular routine, whether it’s daily or several times a week, based on your specific goals.

Start with shorter sessions if you’re new to red light therapy, gradually increasing your exposure as your body adjusts.

Hydrating your skin before and after treatment can also enhance results, as healthy, well-moisturized skin responds better to light therapy.

This is most important for individuals with dry skin, as red light therapy can exacerbate dry skin.

It’s also helpful to track your progress—take note of any improvements in your skin, mood, or pain levels over time, so you can adjust your sessions as needed.

Finally, combining red light therapy with other wellness practices, such as good sleep, balanced nutrition, and physical activity, can further enhance its positive effects, allowing maximum synergy between the different aspects of your health.
