What is red light therapy?
Photobiomodulation therapy (PBMT) is a type of light therapy that uses red light of specific wavelengths to penetrate tissues and stimulate cells.
Red light therapy can speed wound recovery, relieve pain, reduce inflammation, stimulate hair growth, and treat certain types of acne.
Scientists still don't fully understand the cellular and molecular dynamics behind these results, and a common explanation is that photons of red light are absorbed by an enzyme in mitochondria, the cells' energy factories.
This stimulates metabolic processes that cause the mitochondria to produce more adenosine triphosphate (ATP), a molecule that facilitates cellular chemical reactions and is thought to increase a person's energy levels.
Red light boxes have been used to treat Seasonal Affective Disorder (SAD) since the 1980s.
It is known that exposure of skin to sunlight for 20-30 minutes allows the body to absorb enough vitamin D.
In areas of the world where there is too little sunlight in the winter, people who do not receive enough sunlight can develop depressive symptoms (seasonal affective disorder). A simple and effective treatment for this disease is to expose the patient to bright light during the day. .
There is also blue light, especially blue light with a wavelength of about 460-480 nanometers, which will affect the body's circadian rhythm - making you unable to sleep at night. Therefore, wearing blue light-blocking glasses and turning on blue light-filtering software can more or less help. Help you sleep.
Infrared light is also called infrared ray. Infrared ray is one of the many invisible rays in the sun's rays. It was discovered by the British scientist Herschel in 1800.
He separated the sunlight with a prism and placed thermometers on the ribbons of various colors. He found that the thermometer on the outside of the red light heated up the fastest.
Therefore, it is concluded that the wavelength of infrared rays in the solar spectrum is larger than that of visible light, with a wavelength of 0.75 to 1000 μm.
Infrared physiotherapy is a type of phototherapy. It transmits infrared rays to the skin (about 5 mm) through an infrared physiotherapy device.
When your cells are illuminated by red light wavelengths, the vibrations of molecules and atoms will be accelerated, and the distance between them will be widened, which can increase the local temperature.
Changes in cell permeability, enzymes, etc. accelerate metabolism, increase caloric proteins (special enzymes that help protect cells from stress and early death), produce many regenerative effects, and reduce cell damage, muscle fatigue, joint pain, and inflammation. plays a central role in oxidative stress.
