Being pregnant is a special experience, but it can also be physically demanding. Back pain, tired muscles, or even a simple cold can feel more intense. Since many prefer to avoid medication during pregnancy, interest in natural relief methods is growing. One of these is light therapy. But how does it work, and is it safe during pregnancy?
Note: This information does not replace medical advice. Always consult your doctor or a qualified healthcare professional before using light therapy during pregnancy.

Common pregnancy symptoms
Pregnancy can bring a variety of physical discomforts. Here are some of the most common:
- Back and pelvic pain: Caused by extra weight and changes in posture.
- Muscle and joint stiffness: Especially in the lower back, shoulders, and neck.
- Tired or heavy legs: Often due to reduced circulation or fluid retention.
- Tension headaches: Triggered by stress, hormonal shifts, or muscle tension.
- General fatigue: A result of both physical and hormonal changes.
What is light therapy?
Light therapy involves the use of specific wavelengths of light to stimulate the body and relieve certain symptoms. There are various types of light therapy, with red light therapy and infrared therapy being the most common.
- Red light therapy uses visible red light that primarily stimulates the skin and superficial tissues. It can help with issues such as skin aging, scars, and surface-level inflammation.
- Infrared therapy penetrates deeper into the body, reaching muscles and joints. It is often used to treat muscle pain, stiffness, or joint problems. Depending on the nature of the symptoms, one form may be more effective than the other, or a combination of both may be applied.
During pregnancy, red light is generally considered the safer option, as infrared light affects deeper tissues. Always consult a doctor before using either form of therapy.
How does red light therapy help with these symptoms?
Red light therapy can provide relief in various ways:
- Mood & Well-being: Stimulates serotonin production, which may help ease mood swings and prevent prenatal depressive symptoms.
- Sleep Quality: Regulates evening melatonin production, supports the natural sleep-wake cycle, and promotes better rest.
- Skin Health: Boosts collagen production and improves skin elasticity. May help reduce stretch marks and pigmentation changes such as melasma.
- Cellular Energy & Recovery: Activates mitochondria to produce more ATP (energy), which can lead to increased vitality and reduced fatigue. Speeds up the body's recovery processes.
- Circulation & Pain Relief: Improves blood flow, allowing oxygen and nutrients to reach muscles and tissues more efficiently. Reduces stiffness and pain, and helps muscles relax—especially in the back, pelvis, and neck.
- Anti-inflammatory & Tissue Repair: May reduce inflammation and support tissue healing.
- Natural Approach: Provides symptom relief without medication, which can be especially valuable during pregnancy.
Is It safe during pregnancy?
Although research on red light therapy during pregnancy is still limited, one study involving 380 pregnant women showed no negative effects for either mother or child. In general, red light devices are considered safe when used properly: not too hot, not for too long, and never directed at the abdomen.
During pregnancy, extra precautions are essential. Treatment should be limited to areas such as the back, shoulders, or neck. Always consult a doctor, midwife, or gynecologist before use.
Possible Effects
Effects on the unborn child: When used correctly, meaning not directly on the abdomen and in moderate doses, red light therapy is considered harmless for the baby. The light does not penetrate deeply enough to reach the unborn child directly.
It only becomes risky in cases of intense local overheating of the abdomen, which could raise the temperature inside the uterus and potentially be harmful.
That’s why it’s important to use red light therapy only on safe areas like the back, neck, or shoulders, and always under medical supervision. Want to learn more about safety? Read our detailed blog!
When Should You Be Cautious?
Although studies suggest red light therapy may help with symptoms like depression, there is still insufficient evidence to confirm its complete safety during pregnancy.
Caution is advised, especially in cases of high-risk pregnancy, elevated body temperature, high blood pressure, or existing medical conditions. Whether light therapy is suitable depends heavily on the individual situation and correct application. When in doubt, medical advice is essential.
Red light therapy can be safely applied to the face during pregnancy and offers a natural way to care for the skin, improve circulation, and stimulate collagen production.
However, some experts warn that hormonal changes may make the skin more sensitive to inflammatory reactions. That’s why it’s always important to consult your doctor before starting treatment.
Tips for safe use
- Distance from the lamp: At least 30–50 cm
- Duration: Maximum of 10–15 minutes per session
- Frequency: 2–3 times per week
- Never direct the light at the abdomen
- Protect your eyes with safety goggles or keep them closed
- Always listen carefully to your body
Conclusion
Light therapy can gently and naturally relieve various symptoms. Red light therapy is often considered safe during pregnancy, provided it’s used correctly: not too hot, not too long, and never aimed directly at the abdomen.
Infrared therapy penetrates deeper and therefore requires extra caution, especially for pregnant women. When in doubt, always consult a doctor or midwife.
