Near-Infrared Light Therapy (NIR Therapy for short) is a method of treating the human body with near-infrared light (the wavelength range is usually between 700nm and 2500nm, but the commonly used ranges are 600nm to 950nm or 900nm to 1800nm). Near-infrared light therapy is a kind of light therapy, through the irradiation of near-infrared light, using its penetrating and warm effect in human tissues, to achieve the purpose of treating or improving certain diseases and symptoms.
Principles of Near Infrared Light Therapy
After irradiating the human body, near-infrared light is able to penetrate the surface layer of the skin and enter the subcutaneous tissue or even deeper tissues. Its warming effect can promote local blood circulation and increase the permeability of capillaries, thus improving tissue nutrition and metabolism. Zusätzlich, near-infrared light can also promote cell metabolism, enhance cell activity and regenerative capacity, and help tissue repair and wound healing.
What is the Difference Between Light Therapy, Rotlichttherapie, and Near Infrared Therapy?
Light therapy is exposure to light that is brighter than indoor light and is used to help with cognitive abilities that may suffer due to depression, seasonal affective disorder, or sleep disorders. If you have ever heard of a “light box,” or if you have one in your home, this is a form of light therapy. Exposing people to light for 30 minutes to a few hours a day can help stimulate a change in the levels of chemicals and hormones within the body that affect mood. Unser Körper nutzt Lichtsignale, um bestimmte Funktionen wie den Schlaf zeitlich zu steuern, Aufwachen und so weiter. Wie wir schlafen, wie aktiv wir sind, und wie wir uns fühlen, werden durch unsere innere Uhr reguliert. Wenn unseres ausgeschaltet ist, unser Energieniveau, Fähigkeit zu schlafen, und Stimmung werden beeinflusst! Hier kann eine Lichttherapie hilfreich sein.
Die Lichttherapie liegt im sichtbaren Teil des Lichtspektrums (zwischen 400 nm zu 480 nm). Obwohl es sich geringfügig von der Farblichttherapie unterscheidet, Lichttherapie kann helfen, Schlafmuster zu regulieren, Stimmung verbessern, die kognitive Leistungsfähigkeit steigern, und Hormone regulieren.
Rotlicht vs. Nahinfrarottherapie
Rotlichttherapie und Nahinfrarotlichttherapie fallen in ein ganz anderes Lichtspektrum. Die beiden werden oft als dasselbe verwechselt, sind aber in Wirklichkeit recht unterschiedlich. Rotes Licht fällt in den sichtbaren Teil des Lichtspektrums dazwischen 630-700 nm on the electromagnetic scale and is used to treat the surface of the skin. Near-infrared wavelengths fall into the invisible part of the light spectrum between 700 Und 1200 nm. So what does this mean? The longer the wavelength, the deeper the penetration to deliver energy to the cells, stimulating healing and relieving pain. Various cell and tissue types each have their own unique light absorption methods at varying wavelengths. This means certain tissues absorb certain kinds of light. Zum Beispiel, light vibrating at the blue wavelength is great for skin while other colors may penetrate the skin more deeply – see LEDs in Dermatology study.
The optimal NIR technology is done by LED as you are able to control the surface temperature. Also LED disperses over a larger surface area than a RED light halogen or laser. Another major difference between LED and halogen and Laser is the way light energy is delivered (optical power output – OPD). The OPD of LED Near is measured in milliwatts and laser and halogen are measured in watts. This allows LED to have a more gentler delivery as it will not damage tissue and will not have the same risk of accidental eye injury. Also LED NIR disperses over a greater surface area giving a faster treatment time.
NASA research has found that the NIR electromagnetic frequency band of energy penetrates deeply into the body and can have a healing effect on our individual cells. Zum Beispiel, inside the mitochondria of every cell are receptors that respond to near-infrared wavelengths. The light triggers an increase in cell metabolism, protein synthesis (including collagen), and anti-oxidant activity (meaning the cells detoxify). Zusätzlich, it reduces inflammation and pain while simultaneously triggering growth and regeneration in the cells.
Zusamenfassend, light therapy affects mood, circadianer Rhythmus, and other body processes, while Near Infrared Therapy acts as a pain reliever and cell rejuvenator – two VERY different forms of energy, but both beneficial.
Benefits of Near Infrared Therapy:
- Verbessern Sie die Durchblutung: NIR light irradiation can dilate blood vessels, fördern die Durchblutung, and increase blood flow, thus improving nutrition and oxygen supply to local tissues.
- Promote the dissipation of inflammation: By increasing the phagocytosis and metabolic activity of cells, NIR light helps to eliminate inflammatory mediators and swelling and promotes the dissipation and absorption of inflammation.
- Schmerzen lindern: Die Bestrahlung mit NIR-Licht kann die Erregbarkeit von Nerven verringern und die Übertragung von Schmerzsignalen verringern, und sorgt so für Schmerzlinderung.
- Fördern Sie die Gewebereparatur: NIR-Licht kann die Proliferation und Differenzierung von Zellen wie Fibroblasten beschleunigen, Endothelzellen, und keratinisierte Zellen, Förderung der Gewebereparatur und Wundheilung.
- Anti-Aging: Auch die NIR-Lichttherapie kann die Hautstruktur verbessern und die Kollagenproduktion fördern, hilft, Falten und Verfärbungen zu reduzieren und Anti-Aging-Effekte zu erzielen.
Anwendungen der Nahinfrarot-Lichttherapie
Die Nahinfrarot-Lichttherapie hat ein breites Anwendungsspektrum im medizinischen Bereich, einschließlich, aber nicht beschränkt auf Folgendes:
- Chirurgische Versorgung: zur postoperativen Wundheilung, Entzündungskontrolle, Wundheilung, usw.
- Pflege bei Verbrennungen: für Verbrennungspatienten, Die NIR-Lichttherapie kann die Heilung von Brandwunden fördern und das Infektionsrisiko verringern.
- Schönheitsbereich: zur Hautaufhellung, tightening, Anti-Aging, and other beauty programs.
- Schmerzmanagement: For chronic pain patients, NIR light therapy can be used as a non-invasive pain management method.
To summarize, near-infrared light therapy is a method of using near-infrared light to treat the human body, which has a variety of effects, such as improving blood circulation, promoting the dissipation of inflammation, Schmerzen lindern, und Förderung der Gewebereparatur. It has a wide range of application prospects in the field of medicine and cosmetology.
