ISO60825 does NOT tell the difference between coherent and incoherent light. You tread an LED exactly as you would a laser: if you apply ISO60825 and determine that the light dose from your LED is intrinsically safe (i.e. class 1), then this is a sound indication, aside from in severe cases of the diseases I mention above. The other factor I
The action of IR light on water dynamics in membranes, mitochondria and/or cells could modulate signaling pathways, production of reactive oxygen species (ROS), ATP (adenosine triphosphate), Ca 2+, NO, and inositol phosphates group [ 13 – 16 ]. Secondary effects are always preceded by primary effects, including stress signaling, metabolic
Sun exposure causes wrinkles, collagen loss and increased pigmentation. Red Light Therapy can reverse photodamage from UV rays. It can soften the skin’s texture, increase collagen and elastin, and even out the skin’s tone. There is one exception, in that people with pigmentation issues might need to avoid infrared light in certain areas.
One of the biggest advantages of RLT is that it can be used on specific parts of the body. Oral pain medication, on the other hand, works on pain chemicals and nerve endings all over the body. “Red light treatment delivers focused pain relief,” says Michael Newman, MD, a plastic surgeon in Beverly Hills, California.
But it uses low-level or “cold” lasers to deliver light to the skin; this differentiates it from red and NIR light therapy devices that use light-emitting diode (LED) bulbs, rather than lasers. Typically, low-level laser therapy is only used in clinical settings, whereas a wide variety of red/NIR light devices are available for home use.
The findings suggest that turning off lights at bedtime could reduce the risk of becoming obese. Sleep is important for many reasons. Your body produces hormones while you sleep that help your body grow, build muscle, fight illnesses, and repair damage. Not getting enough sleep can affect your mood, health, weight, and ability to carry out day
