About Red Light Therapy
Red Light Therapy (RLT) is a non-invasive treatment that uses low-intensity red or near-infrared light of a specific wavelength (630-850nm) to illuminate the body. It can penetrate the skin, stimulate cellular energy (ATP) production, promote repair and reduce inflammation.
How Red Light Therapy May Help the Thyroid
Thyroid problems (such as hypothyroidism and Hashimoto’s thyroiditis) are often accompanied by fatigue, slowed metabolism and inflammation. Studies have shown that red light therapy may support thyroid health in the following ways:
1. Reduce thyroid inflammation
Autoimmune diseases such as Hashimoto’s thyroiditis are associated with chronic inflammation.
Red light can reduce inflammatory factors (such as TNF-α, IL-6) and relieve thyroid tissue damage.
2. Improve blood circulation
The thyroid gland needs a good blood supply to function properly.
Red light can promote microcirculation, help nutrient delivery and waste removal.
3. Support cell repair
Near-infrared light (such as 850nm) penetrates deeper and may help damaged thyroid cells restore function.
4. Relieve symptoms related to hypothyroidism
Some users report increased energy, improved dry skin, and enhanced metabolism (more research is needed to confirm this).
How to use red light therapy to support the thyroid gland?
Choosing a device:
Wavelength recommendation: 660nm (red light) + 850nm (near infrared) combination is best.
LED panels or handheld devices (such as Merican) can be used.
Irradiation method:
Position: Directly irradiate the thyroid area of the neck (below the Adam’s apple).
Time: 10-15 minutes each time, 3-5 times a week.
Distance: Keep the device 15-30 cm away from the skin (adjust according to the power of the device).
Precautions:
Avoid overuse (may cause temporary dryness or redness).
Pregnant women, patients with hyperthyroidism or thyroid nodules should consult a doctor first.
