Light (visible, UV, and IR) is essential to life on Earth and is an integral part of the human experience. Our understanding of how the human body responds to light is constantly growing and evolving. There are three main systems in our bodies that utilize light: The Visual System – for vision.

Actinic (also known as solar) keratoses are bumpy, precancerous lesions that develop as a result of sun exposure, and approximately 10 percent of these growths can become squamous cell carcinoma if left untreated. To prevent that from happening, dermatologists look to blue light therapy. When the lesions are treated with a photosensitive chemical a...
Exposure to blue light can also help us feel more alert, according to one 2006 study. Study participants were divided into two groups, exposed to either blue or green light, and then asked to rate their energy levels. The subjects shown blue light described themselves as feeling more awake, and demonstrated quicker reaction times and longer attenti...
When the human eye is exposed to a bright light, cells in the retina connected to the hypothalamus region of the brain (which controls circadian rhythm) are stimulated. For people who suffer from Seasonal Affective Disorder (SAD), those rhythms can become disrupted once the days get shorter and there’s less sunlight to take advantage of. Artificial...
Some exciting research is being done investigating how light-sensitive cells called ipRGCs and the melanopsin protein within can influence how our brains process information. In one study, subjects were shown blue, orange, or green light while they performed a memory assignment, then were asked to sit in the dark. After that, they did the memory te...
You might be surprised at how an increase in lumens (the measurement of light intensity) can affect your accuracy when it comes to focusing on tasks and fine motor control. One study indicated that pharmacists who used a light source with at least 1500 lux (measuring light concentration spread over a specific area) had an error rate of only 2.6 per...
A 2005 study that compared hospital patients with varying exposures to sunlight found that those who received 46 percent more of the sun’s rays than those who were stationed away from hospital windows needed 22 percent less pain medication on an hourly basis than those who didn’t have as much access to light.
While sunlight is a common source for this valuable vitamin, our bodies may be able to metabolize it with help from exposure to artificial light containing UV radiation as well. The finding may be beneficial to shift workers or those who have only limited access to sunlight.
Warmer lighting, as opposed to blue light, tends to be less effective at suppressing melatonin production, which allows us to settle into a more routine sleep/wake cycle. Ensuring your night lights are dim, red bulbs could improve your rest.
In 2012, scientists discovered a peculiar quirk of our pupils: They’ll constrict when presented with graphic designs that give off the appearance of having a bright center, even when no actual light is being transmitted into the eye. The illusory perception may be part of our bodies’ efforts to protect us from exceptionally bright light sources. Wh...
Mar 26, 2021 · For example, light of sufficient potency early in the biological night elicits a delay in rhythms whereas light much later in the night will cause an advancing shift to an earlier time.

Oct 19, 2023 · The head of the railroad worm glows red, while its body glows green. Different luciferases cause the bioluminescence to be expressed differently. Some organisms emit light continuously. Some species of fungi present in decaying wood, for instance, emit a fairly consistent glow, called foxfire.
Chemical reactions that take place inside living things are called biochemical reactions. The sum of all the biochemical reactions in an organism is called metabolism. Metabolism includes both exothermic (energy-releasing) chemical reactions and endothermic (energy-absorbing) chemical reactions.
Each of the various effects of light on mammalian tissues can be classified as direct or indirect, depending on whether the immediate cause is a photo-chemical reaction within the tissue or a neural or neuroendocrine signal generated by a photoreceptor cell. When the effect is direct, the
