Pregnancy, Breastfeeding & Mastitis: How can RLT help mothers?

Pregnancy, Breastfeeding & Mastitis: How can RLT help mothers?

As a new mother, breastfeeding can be one of the most rewarding yet challenging experiences. From sore nipples to concerns about milk supply, the journey often comes with hurdles. Enter red light therapy (RLT), also known as photobiomodulation, a non-invasive treatment using red and near-infrared light to promote healing and reduce inflammation. Recent research highlights several potential benefits of RLT for breastfeeding mothers, particularly in easing physical discomforts and supporting postpartum recovery. In this blog post, we’ll explore the science-backed advantages of RLT, based on studies available as of June 2025, and why it might be worth considering for new moms.

What is Red Light Therapy?

Red light therapy involves exposing the skin to low-level red or near-infrared light, which penetrates tissues to stimulate cellular repair and reduce inflammation. It’s been used for everything from skin rejuvenation to pain relief, and now, studies are shedding light on its potential for breastfeeding mothers. The therapy is non-invasive, drug-free, and generally considered safe, making it an appealing option for addressing common postpartum challenges.

Key Benefits of Red Light Therapy for Breastfeeding Mothers

Here’s a detailed look at the positive effects of RLT, drawn from peer-reviewed studies and reputable sources, tailored to the needs of breastfeeding moms.

1. Relief from Nipple Pain and Fissures

Sore nipples and fissures are common struggles in the early weeks of breastfeeding, often making the experience painful. Research shows that RLT can significantly reduce nipple pain and promote healing. A 2024 study found that mothers receiving 12 sessions of low-level laser therapy reported lower pain scores on the visual analogue scale compared to those using topical cream. The RLT group also saw greater infant weight gain, suggesting improved breastfeeding success (Coca et al., 2024). Another triple-blind, randomized trial showed that laser therapy relieved nipple pain from lesions one day faster than a sham treatment (Coca et al., 2016). These findings indicate that RLT could make breastfeeding more comfortable, helping mothers stick with it longer.

2. Support for Milk Production

Low milk supply is a top concern for many breastfeeding mothers. RLT may offer a boost by increasing serum prolactin levels, the hormone responsible for milk production. A 2025 study on primiparous mothers supplementing with formula found that those receiving 12 sessions of low-level laser therapy over three weeks had greater increases in prolactin, as well as improved breastmilk composition (higher lactose, protein, and fat) at three weeks and three months postpartum. Another study compared RLT to domperidone and electroacupuncture, finding that RLT increased prolactin, infant weight, and maternal perception of milk production more than domperidone alone, though less than electroacupuncture (Maged et al., 2019). While more research is needed, these results suggest RLT could be a helpful tool for mothers struggling with milk supply.

3. Treatment for Mastitis

Mastitis, a painful breast infection, can disrupt breastfeeding and cause significant discomfort. A study from China found that high-intensity red light (630 nM) combined with antibiotics was more effective than antibiotics alone in healing mastitis and preventing recurrence. By reducing inflammation and promoting tissue repair, RLT offers a complementary approach to managing this condition, potentially allowing mothers to continue breastfeeding with less pain.

4. Aid in Postpartum Recovery

For mothers recovering from cesarean sections, RLT may support wound healing, easing the physical toll of childbirth. A small study found that low-level laser therapy applied for 15 minutes over three consecutive days post-cesarean appeared to aid wound healing, though prolactin levels remained unchanged (Mokmeli et al., 2008). Faster recovery can reduce stress and improve overall well-being, indirectly supporting breastfeeding by allowing mothers to focus on their baby.

Safety Considerations

One of the most reassuring aspects of RLT is its safety profile. According to the LactMed database, no adverse effects on breastfed infants have been reported in studies involving RLT for breastfeeding mothers (National Library of Medicine, 2025). However, because research is still limited, experts recommend consulting a healthcare provider before starting RLT, especially to ensure it’s appropriate for your specific situation. 

How to Incorporate Red Light Therapy

If you’re interested in trying RLT, here are some practical tips:

  • Consult Your Doctor: Always discuss RLT with your healthcare provider, especially while breastfeeding, to ensure it’s safe for you and your baby.
  • Choose a Reputable Device: Look for LLT's medical-grade RLT devices designed for home use, as recommended by professionals
  • Follow Professional Guidance: Work with a lactation consultant or therapist trained in RLT to target specific issues like nipple pain or mastitis.
  • Start Slow: Begin with short sessions (e.g., 10-15 minutes) and monitor how your body responds.

Conclusion

Red light therapy offers exciting potential for breastfeeding mothers, with research suggesting benefits like reduced nipple pain, improved milk production, mastitis treatment, and enhanced postpartum recovery. While the evidence is promising, it’s not conclusive, and more studies are needed to fully understand its impact. For now, RLT appears to be a safe, non-invasive option that could make breastfeeding and recovery more manageable, but always consult your healthcare provider before starting. By addressing common challenges with a science-backed approach, RLT might just be the support new mums need to thrive during this special time.
