Dave Asprey, the Father of Biohacking, coined th e term junk light to emphasize the negative impacts that overexposure to blue, green and violet waveleng t hs can have on a person’s health and performance. Context - With the growing use of energy saving lamps and the development of new lighting technologies, comes the worry that some people who have conditions that react to light might be negatively affected by this shift. For instance, if they use CFLs it would be better if they used those with a double envelope. For succulents, you need lights that … According to the National Sleep Foundation, "Those who report poor quality sleep also report poor quality health." Replace them with incandescent bulbs or use candles from time to time. Since the dawn of time, humans have worshipped the sun. From the WebMD Archives.

Once you provide a way for natural light to enter the basement, there is less of a need for artificial light, which means your electric bill will be noticeably cut. Answer Save. I've noticed that the glare of my computer is quite harsh to the eyes and makes me feel sleepy, but with natural light, i feel happier, almost refreshed This means that when we’re looking at the digital screens on our mobile phones and computers our natural sleeping and waking patterns (the circadian rhythm) can become disrupted. Personally, I consume massive amounts of water each and every day. Artificial lighting has many different applications and is used both in-home and commercially. 'Light is critical for our health and wellbeing.' This light is why you slather on sunscreen — the lotion protects you from two kinds of UV light, UVA and UVB, which are responsible for premature skin wrinkling, sunburns and skin cancers. The eye’s retina is exposed to visible light wavelengths between 400 and 700 nm (nanometres), as well as some short infrared wavelengths. Where It Gets Bad. UV and IR can be subdivided according to their wavelength into narrower bands (UVA/UVB/UVC for ultraviolet, with UVA being the closest to visible light, and IRA/IRB/IRC for infrared, with IRA being the closest to visible light.). Early stages of AMD are yellowish deposits (drusen) and pigmentary changes of retinal pigment epithelium (RPE) alongside significant loss of vision. Artificial lights are available in a wide variety of shapes, sizes, colors of light emitted, and levels of brightness. What are the effects on people who have conditions that make them sensitive to light? The same goes true for artificial light — you need just the right amount of it to function. Succulents under Artificial Light: Do’s and Dont’s. I've noticed that the glare of my computer is quite harsh to the eyes and makes me feel sleepy, but with natural light, i feel happier, almost refreshed . Relevance. Because of how commonplace artificial lighting is in today’s society, there is a greater risk of over-exposure to blue light. Natural sources of blue light increase our wakefulness and regulate our circadian rhythm so we rely on blue light to regulate our bodies. These tend to give off more Ultraviolet (UV) rays that may cause skin problems, prematurely age materials like plastic or leather, and cause photos to fade. Remember to expose yourself more often to natural sunlight to get your daily dose of endorphins and vitamin D. If you can’t avoid artificial light especially at night, definitely install Iris to start sleeping better than ever. can see more clearly so you can easily recognize the surroundings, make it easy to do indoor activities, create a comfortable and safe environment; make an objects and rooms more artistic; Various types of artificial light … artificial light and its disturbance to the daily and seasonal patterns of plants and plant– animal interactions. According to a worst case scenario the highest measured UV emissions from lamps used in offices and schools, but not the very low emissions lamps used for household lighting, could add to the number of SCCs in the EU population. Your circadian rhythm is controlled by a part of your brain called the hypothalamus. The idea artificial light from screens is keeping people awake at night is flawed, say scientists who have been studying the best type of lighting to nod off to. The Truth About Flavored Water Drops & Powders – Is Flavored Water Bad for You? Take, for instance, the flickering of a fluorescent light. With 43% of adults working in a job that requires the prolonged use of a computer or digital screen, it’s important to be aware of the potential dangers of blue LED light sources to avoid over exposure to dangerous types of light. Artificial light has transformed how the human race has lived in the past 100 years or so. That can include a long list of things you can’t pronounce, as well as manufactured additives like propylene glycol, which is also used in aircraft de-icer. It is the most common cause of blindness in the elderly population and accounts for 8.7% of blindness worldwide. Do your research. During light therapy, you sit or work near a device called a light therapy box. He says, “Junk light is worse than junk food; it’s the high fructose corn syrup of lighting. Halogen lamps follow the same principle but they also contain a gas inside the tube that makes the light much brighter and the lamp more efficient. The wavelength of visible light determines its colour, from violet (shorter wavelength) through to red (longer wavelength). Both natural and artificial light can also disrupt the human body clock and the hormonal system, and this can cause health problems. In spite of its claim to being natural, it contains less than 2% of natural flavoring and the additional 98% is comprised of junk and poisons. How and where are people exposed to artificial light? The majority of lamps are classified as “exempt from risk” and most of the rare exceptions are classified as “low risk” . Research has fo Long term exposure to low levels of UV radiation add a very small percentage to the lifetime risk of developing squamous cell carcinoma (SCC) but could lead to an increase in the number of SCCs in the population. 7. This is because of how light interferes with the production of melatonin, which should peak at night (when it is naturally dark) and then reduce during the day (when it is naturally light). UK Distributer for Solarspot Daylighting Systems. Okay, let’s begin with the sunlight. The sun often gets a bad rap for affecting our health badly, but the truth is it has tons of positives for our overall health when we’re getting just enough of it. Anonymous. This mainly to give me an idea of how objects might look in light polluted areas. You can use them in pot culture, house garden, sowing, farm, breeding, flower exhibition, green house and so on. But is it bad for your skin? If you continue to use this site we will assume that you are happy with it. Children and older people are most vulnerable to developing AMD. Image : LEDs do not emit UV. It is tied to our metabolism and gives us energy; it’s blue light for example that encourages plants to bloom. The box gives off bright light that mimics natural outdoor light. In fact, by the age of 65 around half of our protection on our eyes is gone, which significantly increases our susceptibility to developing eye diseases such as macular degeneration. These lamps will give you the best lights which are great for photosynthesis, blooming and fruits and they will ensure that your plants have their colors! More... Short-term UV effects from artificial lighting on healthy people are thought to be negligible. Radiation can cause burns but this is rare with domestic lamps. If you're trying to grow houseplants indoors, you'll find that some rooms of your house are low in natural light. This happens when blue light penetrates the macular pigment of the eye which causes the retina to breakdown. Some people with diseases that make them sensitive to light claim that the energy-saving lamps (mainly compact fluorescent lamps (CFLs) and light emitting diodes (LEDs)) that have been brought to replace incandescent lamps, make their symptoms worse and play a role in a wide range of diseases. The blue component of visible light can harm the retina but this is only caused by accidental exposure to sunlight or to very high intensity artificial lights so is rare. The components of artificial lighting have an adverse affect on your physical and mental health, but how bad is the issue really? In 2013 alone, there were 3 awesome studies that have focused on “Light at Night” (pretty self-explanatory): The basic design is also a gas sealed inside a tube but there are many different variations. Having lower melanin levels makes children and teenagers more vulnerable to blue light exposure and susceptible to developing AMD. This makes the eye more vulnerable to cell degeneration which can lead to problems such as age-related macular degeneration (AMD), glaucoma and cataracts. Artificial lights are available in a wide variety of shapes, sizes, colors of light emitted, and levels of brightness. But do not wrongly assume that all artificial sweeteners are safe for you to use. Some artificial light however, is just plain not good for you. There have been significant advances in the management and prevention of AMD, and with the introduction of anti-angiogenesis therapy which can prevent blindness and in some cases, restore vision. Is artificial light worse than Moonlight? By lighting your house with natural instead of artificial lighting, your body will be less exposed to a harmful amount of blue light that will keep your body awake and alert longer than it needs to be. Artificial warm light includes sources like incandescent bulbs and LED bulbs, which are more energy efficient. The wavelengths in sunlight contain all the colors of the rainbow while artificial light often lacks a few. Plants need to get a certain amount of light for photosynthesis to occur. Avoid using energy efficient LED light bulbs which are bad for your health. The advent of electricity brought incandescent lights where typically a metal filament is sealed inside a glass tube and electricity is used to heat up the metal until it glows. When it is dark your eyes send signals to the hypothalamus, triggering it to release melatonin (a hormone key to your circadian rhythm), which makes your body tired. Artificial light, as opposed to natural light, refers to any light source that is produced by electrical means. It's estimated that between 1950 and 2000, exposure to artificial light in the UK rose four-fold. These wavelengths vary in size and the size of the wave affects the strength of its energy; the shorter the wavelength, the stronger it’s energy. NATURAL blue light, that comes from the sun, the high energy wavelengths of blue light, collide with the molecules in the air, scattering blue light everywhere. This assumes typical exposures at work and in school to CFLs with the highest level of UV radiation, although in practice, exposure to fluorescent lamps will be lower than this. Visible and IR radiations from artificial lights are unlikely to have any effects on health, unless they are extremely intense and used at close range. Favourite answer. Based on these standard tests the lamps were classified into four Risk Groups: “exempt from risk” (RG0), “low risk” (RG1), “medium risk” (RG2), and “high risk” (RG3) which includes only lamps where a short-term exposure poses a threat. The sun emits radiation over the full range of wavelengths, but the earth’s atmosphere blocks a lot of UV and infrared radiations. When light illuminates matter it can heat it up, and this is the main effect of IR. Blue light has the potential to cause damage to our eye’s retina.

But artificial light, especially the light emitted from electronic devices, is disturbing our natural biorhythm. Blue light, part of the spectrum of visible light, is a high-energy, short-wavelength light. The advanced stages of AMD are dysfunction and death of photoreceptors and ultimately the irreversible loss of the central vision. The ultraviolet and the blue components of light have the greatest potential to cause harm. The easiest way to do this is to regulate your exposure to artificial lighting. Our melanin levels decrease naturally as we age, which means that older people become exposed to higher levels of blue light, with a greater risk of developing AMD. Negative effects to your memory, making it harder for your brain to retain information. Blue light is the visible light at the blue end of the spectrum. Blue light can be both good and bad for you. Our Ocular Lens Pigment (OLP) is what protects our eyes from light exposure and the development of macular degeneration. The Three-Level Structure used to communicate this SCENIHR Opinion is copyrighted by Cogeneris sprl. Artificial light and our circadian rhythm, Artificial light and macular degeneration, Why getting more daylight will transform your health, The things you need to know before buying a solar tube.

The Schepens Eye Institute recommends the use of sunglasses to protect against harmful blue and UV light outdoors. Accessibility tools. However, these effects are due disruption of the natural circadian rhythm, regardless of the type of illumination. Overexposure to UV causes burns in the short term and, over long periods of time, contributes to the risk of developing skin cancer (melanoma) as well as squamous cell carcinoma (SCC) and basal cell carcinoma, (BCC). If you want to use sweeteners without causing any added pain or stress to your life, choose them carefully. SAD is a type of depression that occurs at a certain time each year, usually in the fall or winter. Poor sleep does more than make you feel lousy the following day. In certain doses blue light is beneficial to us, but it becomes harmful when we are exposed to it too often. It is useful to monitor how much artificial light you expose yourself too, especially at night. Blue light … People living in big cities are likely to be most affected by too much artificial light. Water, the adult human body is made up more than 60% of it and it’s the most essential element of all life on earth. There is no evidence that short-term exposure to lamps used normally in offices or at home would cause any damage to the eye. So, is all blue light bad for you? In fact, many of them may actually cause symptoms to worsen or cause additional health concerns. Long-term exposure to UV from sunlight may damage the cornea and cause cataracts but using artificial light normally is very unlikely to have any similar effects.

Visible and IRA radiations penetrate deepest into the skin and eye and can reach as far as the retina. When you’re drinking the flavored stuff, not only are you getting bad coffee—the synthetic flavors also often contain a bizarre mix of chemicals. Photochemical reactions happen in normal, ambient conditions and involve a reaction between energetic photons and an absorbing molecule in the presence of oxygen, which leads to the generation of reactive oxygen species (ROS) that are highly toxic to the retina. The problem lies in the color spectrum that artificial light uses.
