The latest research progress in the red light therapy industry
How does red light therapy promote blood circulation? – The science behind its benefits, from microcirculation to systemic health.
Release time:
2026-01-09
With the rapid development of photobiomodulation (PBM) technology, red light therapy (RLT) is gradually becoming an emerging method for improving blood circulation and tissue metabolism. Its safe, non-invasive, and reusable characteristics have made it a subject of great interest in rehabilitation medicine, sports medicine, and health management.
1. How does red light promote blood circulation?
red light therapy pass630–850nm The wavelength of irradiates skin and tissues,
Stimulates mitochondrial cytochrome C oxidase (Cytochrome C Oxidase) in cells to absorb light energy,
thereby increasing cellular energy molecules ATP (adenosine triphosphate) The generation of .
When cells have sufficient energy, a series of physiological reactions will be triggered:
1. Increased release of nitric oxide (NO): NO is a key factor in vasodilation, which can reduce peripheral vascular resistance and promote blood flow.
2. Microvasculature dilation and capillary permeability enhancement: Helps transport oxygen and nutrients.
3. Improved red blood cell fluidity: Reduce blood viscosity and make blood flow smoother.
4. Increase lymphatic circulation activity: Promote the elimination of metabolites and toxins.
In short, red light therapy works byImprove microcirculation and vascular function, to achieve loop optimization from local to system.

3. What circulatory system-related problems can red light therapy be used for?
Research shows that red light therapy shows positive results in a variety of circulatory-related areas:
1. Poor peripheral circulation (cold hands and feet, numbness)→ Improve microvascular perfusion and increase local temperature.
2. Venous return disorder/varicose veins of lower limbs→ Reduce swelling and promote venous blood return.
3. Diabetic foot/delayed wound healing→ Accelerate tissue repair and angiogenesis.
4. Exercise fatigue and muscle soreness→ Enhance muscle blood flow supply and accelerate lactic acid metabolism.
5. Sub-health state (low circulation metabolism, fatigue)→ Improve systemic circulation efficiency and improve energy status.
The core value of red light therapy lies in “reshaping the body’s self-healing ability from the microcirculatory level.”

- Frequently Asked Questions (FAQ)
Q1: Will red light therapy increase blood pressure?
No. Red light helps balance blood pressure rather than increase it by promoting vasodilation and NO release.
Q2: Can everyone use it?
Safe for use by the general population.
However, pregnant women, patients undergoing cancer radiotherapy, and people with light-sensitive diseases must use it under the guidance of a doctor.
Q3: How to arrange the frequency of use?
It is recommended to use it for 20-30 minutes each time, 3-5 times a week, and use it continuously for more than 4 weeks to observe the effect.
Q4: Can it be used with hot compress or massage?
Can be used together, but it is recommended to wait more than 30 minutes to avoid overheating the skin.
Q5: Can red light equipment be used for corporate customization of brands?
Yes. Our company provides OEM/ODM services, including spectrum design, structural appearance and certification support.
