What is Red Light?
Red light is a type of visible light with a longer wavelength, usually between 620 and 750 nanometers. Its color is at the end of the spectrum, so it gives people a warm and soft visual experience.
Red LED lights are suitable for creating a relaxing, comfortable environment and sleeping. Because it is not as bright or stimulating as cold light, it can bring a comfortable and quiet atmosphere.

Red light does not inhibit the secretion of melatonin
Melatonin is a hormone secreted by the human pineal gland. Its secretion increases at night and helps regulate the circadian rhythm (also known as the biological clock). Blue light, especially light emitted by electronic devices, can inhibit the secretion of melatonin, making it difficult to fall asleep.
The longer wavelength of red light can maintain a normal sleep rhythm and will not inhibit the secretion of melatonin.
Red light helps relax the nervous system
Red light has a soothing effect, which can reduce the excitement of the brain and help the nervous system relax. This makes red light particularly effective in nighttime lighting, providing people with a quiet, comfortable environment and making it easier to enter a deep sleep state.
Red light promotes muscle repair and recovery
Some studies have shown that red light therapy can promote the regeneration of cells and tissues. It can help the body repair. Sleep is extremely important because the body repairs itself while it rests. Red light stimulates the mitochondria, increasing cellular energy metabolism, which speeds up the healing and recovery process.
