What is Light Therapy? Light therapy, also known as phototherapy, involves exposure to specific wavelengths of light to treat various physical and mental health conditions. It is a non-invasive method that utilizes natural or artificial light sources, tailored to address issues ranging from mood disorders to skin conditions. Does Light Therapy Work? Mechanism: Circadian Rhythm Regulation: Light therapy primarily works by influencing the body's internal clock (circadian rhythm). Exposure to bright light, particularly in the morning, can suppress melatonin (a sleep-related hormone) and boost serotonin (a mood-regulating neurotransmitter), helping to reset sleep-wake cycles and improve alertness. Retina Stimulation: Light enters through the eyes, triggering retinal cells to send signals to brain regions that regulate mood and circadian rhythms. This is why devices like light boxes are positioned at eye level. Skin Penetration (Red...
Blue light has many effects on plant growth. First, blue light can significantly increase the content of plant chlorophyll, thereby increasing the photosynthetic rate, which indicates that blue light plays an important role in promoting photosynthetic pigment synthesis. In addition, blue light contributes to plant photosynthesis, promoting green leaf growth, protein synthesis, and fruit formation。 LED grow bar with blue light - Promoting photosynthesis: Blue light can stimulate the production of photosynthetic pigments such as chlorophyll in plants, thereby improving the photosynthetic efficiency of plants and providing more energy and material basis for plant growth. For example, in some plant factories, supplementing blue light can enhance the photosynthesis of plants and promote their growth. - Affecting plant morphogenesis: Blue light has an important impact on plant morphogenesis. It can regulate cell division and elongation in plants, thus influencing morph...
