Red Light Therapy and Pregnancy Wellness

Using Photobiomodulation - Red Light Therapy to Support Pregnancy Wellness

There is a LOT to this topic so I’d suggest starting here with Part 1 and Part 2 first.

Years ago Dr Michel Odent and I shared some emails about fascinating research on using blue light on women to reduce preterm labor contractions - read more here about light and melatonin. At the time it seemed a bit ‘Star Trekky’…could a harmless light really stop labor?

Yes - and the research has evolved significantly in the last 10 years.

Make More Energy to Grow Your Baby and Support Your Health

Pregnancy is a time of excitement, anticipation, and countless changes for expectant moms. While the experience is undeniably exciting and enjoyable for most it also places a significant metabolic strain on a woman's body as it works tirelessly to nurture and sustain new life. When compared with ulta-marathon runners, Tour de France cyclists and other extreme sporting events - pregnant women use more energy every day! No wonder pregnancy can leave us exhausted and depleted in postpartum. Of course, adequate nutrition and rest are important but there’s other ways to give your body the energy it needs - light.

Emerging research suggests that photobiomodulation, also known as low-level laser therapy, can offer valuable support during this transformative time. (These ‘lasers’ are not harmful to cells).

From the moment conception occurs, a woman's body undergoes incredible physiological adaptations to accommodate your growing baby. Hormonal fluctuations, increased blood volume, and the development of the placenta - (a brand-new organ!) contribute to increased metabolic demand on your body’s resources. This demand can lead to discomfort, fatigue, low mood and other pregnancy-related symptoms especially if you weren’t in peak health before becoming pregnancy.

Enter photobiomodulation (PBM/Red Light Therapy) a non-invasive therapy that utilizes low-level light to stimulate healthy cellular activity and promote healing. While its applications are diverse, its potential benefits for expectant mothers are really exciting. It’s possibly the most exciting innovation in health care in decades.

Safety of Light Therapy in Pregnancy

There is limited research on the use of light therapy in pregnancy but all state it is safe (but not to put lights directly on to the bump). Pharma companies won’t be funding any studies that could impact their sales so as you learn more about PBM you’ll see why pharma companies are worried as more and more robust studies are published regarding the many benefits and lack of harm in other populations. Many of the manufacturers of PBM consumer goods will also cover themselves with verbiage of “not recommended in pregnancy". However, the world expert on PBM research, Michael Hamblin, is of the opinion that light medicine/photoceuticals are not harmful in pregnancy, especially when we’re not lighting up the bump. These are the same wavelengths of light that we would be exposed to if we spent more time outdoors in the early morning and dusk. Don’t forget we’re already using light medicine with newborns for jaundice and you probably had some beautiful LEDs on your Xmas tree!

So, while research on its safety and efficacy during pregnancy continues to evolve initial findings are promising, and many practitioners consider it a low-risk option for expectant mothers when compared to medication. A recent RCT demonstrated significant improvements in depression during pregnancy when women used different light sources.

As with any medical intervention, talk to your healthcare provider about using PBM at home - although it’s unlikely that your provider has in-depth knowledge of photoceuticals. Educate yourself, talk to other women using PBM and make an informed decision based on your unique circumstances. Do not use your LED light directly in your eyes and avoid if you are light sensitive or on medications such as antibiotics that cause light sensitivity.

PBM has been used successfully in fertility treatments for many years in Japan and Europe. I’ve written about the benefits of PBM for anyone with fertility challenges here.

Back and Pelvic Pain in Pregnancy

One of the primary challenges during pregnancy is managing discomfort and sometimes pain, especially as your body adjusts to the added weight and strain. Photobiomodulation has been shown to effectively relieve musculoskeletal pain by reducing inflammation and improving tissue repair. For pregnant women experiencing back pain, pelvic discomfort, or other common pregnancy complaints, this gentle therapy can offer much-needed relief without the use of medication with just a few minutes each day.

Reducing Pregnancy Complications

Beyond pain management (I’ll share more on pain management soon), photobiomodulation also supports overall maternal well-being by enhancing cellular function and optimizing metabolic processes. Studies have demonstrated its ability to improve circulation, boost immune function, and accelerate wound healing—all of which are crucial for supporting both maternal health and fetal development.

Perhaps most importantly, photobiomodulation may help mitigate the risk of certain pregnancy complications, such as preeclampsia and gestational diabetes. By promoting vascular health and regulating glucose metabolism, this therapy has the potential to positively influence maternal outcomes and reduce the likelihood of complications that can impact both mom and baby. A study from 2023 demonstrated that more artificial light before bedtime is associated with an increased risk of gestational diabetes - https://www.eurekalert.org/news-releases/982136 and you can learn more here.

Red Light Time - Time to Meditate

In addition to its physiological benefits, photobiomodulation offers a unique opportunity for pregnant women to prioritize self-care and nurture their well-being amidst the demands of pregnancy. By taking time to relax, rejuvenate, and connect with their bodies, expectant mothers can cultivate a deeper sense of harmony and empowerment as they prepare for the arrival of their little one. Practice birth basking as you use your light and connect with your body and baby.

Pregnancy places a significant metabolic load on a woman's body but most of us adapt well, but for some, it can also present challenges that impact maternal well-being. Photobiomodulation offers a gentle and non-invasive approach to supporting pregnancy wellness by reducing pain, enhancing cellular function, and reducing the risk of pregnancy complications.

Does light therapy also help with stretch marks, healing after an episiotomy/tear, cesarean wound recovery? Yes - there’s a lot more to come.

I’d love to hear from you.
