Can You Use Red Light Therapy When Pregnant?

Red light therapy (RLT) uses specific wavelengths of light to interact with the body’s cells. This non-invasive approach has gained attention for its potential wellness applications. Understanding its function is helpful before considering its use during pregnancy.

Understanding Red Light Therapy

Red light therapy, also known as photobiomodulation (PBM) or low-level light therapy (LLLT), involves exposing the skin to red and near-infrared light. These wavelengths, typically ranging from 600 to 1000 nanometers, penetrate the skin and are absorbed by mitochondria within cells. Mitochondria convert this light energy into adenosine triphosphate (ATP), the primary energy currency for cellular activities. The increased ATP production can lead to cellular benefits, including reduced inflammation, enhanced cellular repair, and improved blood circulation. This mechanism contributes to common RLT applications, such as promoting skin health by stimulating collagen production, aiding in muscle recovery, and alleviating various types of pain.

Red Light Therapy and Pregnancy Safety

Using red light therapy during pregnancy requires careful consideration due to limited scientific research on pregnant individuals. Ethical considerations make extensive clinical studies challenging, resulting in a lack of definitive data on its effects on fetal development. While some preliminary studies on low-level laser therapy, a form of RLT, have suggested no risk to the mother or baby and even potential benefits for conditions like late-onset preeclampsia and postpartum depression, many medical professionals remain cautious due to insufficient comprehensive research.

Theoretical concerns regarding RLT during pregnancy include the potential effects of light absorption on fetal cells and changes in maternal body temperature or blood flow that could impact the fetus. RLT generally produces minimal heat, but any additional heat could be a concern. It is widely advised to avoid applying red light therapy directly to the abdomen, pelvis, or breasts during pregnancy to minimize potential direct exposure to the fetus or sensitive tissues. Consulting a healthcare provider before considering any RLT use during pregnancy is strongly recommended.

Safe Approaches for Pregnancy-Related Discomforts

Many individuals explore options to address common discomforts experienced during pregnancy, such as back pain, skin changes, and swelling. Several safe and widely recommended alternatives can provide relief.

For Back Pain:

Gentle exercises like walking, swimming, or prenatal yoga
Applying warm or cold compresses
Using a pregnancy pillow for sleep
Seeking prenatal massage or physical therapy specialized in prenatal care

For Skin Issues:

Moisturizing with natural oils such as olive oil or coconut oil
Using mild, fragrance-free cleansers
Avoiding harsh chemicals
Using non-comedogenic makeup and skincare products

For Swelling:

Staying well-hydrated
Reducing sodium intake
Increasing potassium consumption
Elevating the legs
Taking regular, gentle walks
Wearing comfortable, supportive shoes
