It boosts alertness, helps memory and cognitive function and elevates mood. It regulates circadian rhythm – the body’s natural wake and sleep cycle. Exposure to blue light during daytime hours helps maintain a healthful circadian rhythm.
What does blue light do to your brain?

Why do people use blue LED lights?
Blue light wavelengths produced by electronics and overhead lights boost attention, reaction times and mood, according to Harvard Medical School. This can be great for the daytime when the body needs to be alert, but at night it can become a problem.
What are the beneficial and harmful effects of blue light?
Blue light is exactly that: light with blue wavelengths—which are supposedly beneficial during daylight hours because they boost attention, reaction times, and mood. However, these lights are great for the daytime because they keep us awake, and bad at night because they often impede sleep.
What is the energy of blue light?
about 3.1 eV
Red photons of light carry about 1.8 electron volts (eV) of energy, while each blue photon transmits about 3.1 eV.
What are the benefits of blue light therapy?
Blue light therapy is most commonly used to treat sun damage and premalignant or malignant skin cancer growths. It can actually be used to prevent skin cancer and remove both precancerous skin lesions and cancerous skin lesions that haven’t spread to other areas of the body (or metastasized).

What kind of energy is blue light?
high-energy visible light
Narrow-spectrum blue light (also called blue LED light or short-wavelength LED light) is a type of high-energy visible light, defined as having a wavelength between 400 and 450 nm. This light is common in LEDs (even when used in illumination products) as a carry-over from computer-screen technology.
How long does it take for blue light therapy to work?
Anywhere between two and five sessions are necessary, at 2-4 week intervals, for optimal results. Some people may notice results after a single session.
