The COVID-19 situation has drawn the attention of the world to the subject of"viruses."What are viruses,how does one treat them,and other such questions are highly controversial with very many different viewpoints.
One fact that seems to be agreed upon by everyone,is that viruses,at least the kind of"influenza"type of viruses that are seasonal,are a problem in the winter months,but not so much during the summer months.
Since daylight hours are extended during the summer,most of the research on this topic has surrounded Vitamin D,a vitamin best obtained from the sun.
But there is much more to this topic of"light,"and its effect on human health,than just Vitamin D.
Given how much attention has been given to the"coronavirus"topic,it is time to look at this issue more closely to see if there are factors during the shorter daylight winter times that can be studied and understood to improve our health during this time,without always looking for a drug or vaccine to cure everything.
So I assigned this topic to Health Impact News independent researcher and writer Crystal Lauer.She took over a month to research the topic.
During that time,President Trump and a team of researchers working with William Bryan in the Science and Technology division of the Department of Homeland Security,announced results of some their own studies within their laboratory looking at the effects of"solar radiation"and its effect on the Coronavirus,which seems to confirm that some of the research presented in this article may apply to COVID-19.
在那段时间里，特朗普总统和国土安全部科学技术部的研究人员与 William Bryan 一起工作，宣布了他们自己在实验室里研究"太阳辐射"的影响及其对冠状病毒的影响的一些研究结果，这似乎证实了本文中提出的一些研究可能适用于新型冠状病毒肺炎。
Of course,since this is a preventive measure with no patented drugs involved,the studies were quickly condemned by the medical industry,and an off comment made about disinfectants was what the corporate-sponsored"mainstream"media decided to focus on instead.
While Crystal was hesitant at first to spend so much time researching this topic,being a busy homeschool mother,in the end she reported that based on her research,her family made some big changes to their lifestyles to take better advantage of the healing power of natural light,and as a result she reported:
We found that we all are sleeping better,have much more mental energy and are overall feeling far more relaxed,even in the midst of this pandemic.
The Influence of Natural and Artificial Light on Human Biology
The eyes are not only the windows to the soul,but the window through which light influences our biology,and while the radiation absorbed through the eyes is particularly influential on our cells,scientists suggest it is not the only way light,whether thermal or non-native,is able to affect our health.
Human cells,and in general every living thing,are optimized by the sun's broad full spectrum of solar radiation,which starts with the higher energy UV(ultra-violet)rays beginning in the invisible range,progressing through the visible range and ending with the red-to near-infrared at the far opposite side of the spectrum.
The thermal radiation from sunlight holds the complete variations of wavelengths needed to drive our metabolic processes,balance our endocrine system,power our mitochondria,strengthen and build our bones,produce beneficial levels of the hormones dopamine and melatonin and even help prevent pathogens from damaging our bodies.
The sunlight is also known as a Chronobiologic,signaling to non-vision related receptors in our system,the changes in seasons and environment.Approximately 125 million photoreceptors in your retina are neurons transforming light waves into electrical signals which are sent to the brain.
Morning sunlight,which has the most blue light in it,will increase alertness,improve cognitive function and suppress melatonin,the sleep hormone produced in the pineal gland,when exposure occurs within the first couple hours after rising.
The rays contained in the visible blue and ultraviolet parts of the spectrum,which vary in wavelength from 380 Nanometers to 500 nanometers,are largely responsible for synchronizing your body's clock,or Circadian rhythm,to the 24-hour solar cycle,with their short highly active waves.
Sunlight Directly or Indirectly Influences Almost Every Process in our Physiology
Extensive studies suggest that mitochondria,the powerhouse of our cells,use the near-infrared radiation,which makes up 42 percent of the sun's light,to produce Adenosine Triphosphate(ATP),an organic compound that provides energy to the cell.
By altering the physical properties of the water inside the cell's membrane,the body's most prolific chromophore which is a molecule which absorbs light,red-to near-infrared(R-NIR)light turbo-charges chemical reactions which result in cellular energy,while largely down regulating reactive oxygen species(ROS),which are responsible for oxidative stress.
This means that at an atomic level,cellular respiration allows photons in both red-and near-infrared light to excite electrons.Theses electrons break up nitric oxide bonds which compete with oxygen and clear the way for hydrogen ions(H+)to make their way through the process which will eventually lead to them becoming ATP molecules more efficiently.
这意味着在原子水平上，唿吸作用可以让红光和近红外光中的光子激发电子。这些电子打破了与氧竞争的一氧化氮键，为氢离子(h+)清除了道路，最终使它们更有效地成为 ATP 分子。
This influence of red-and-infrared light on the cellular respiration has shown to be beneficial for the reduction of inflammation and pain,to improve muscle and wound recovery and even affect athletic performance for the better.
Another Way the Natural Spectrum of Light Provides Health Benefits is Through its Influence on the Immune System
By now most people are aware of the importance of Vitamin D,an ancient signaling molecule which allows the human body to cope with the increased absorption from UVB rays as the seasons change and the solar radiation in the UV range becomes more abundant.
Sunlight is efficient in producing Vitamin D,being reliant on the number of photons from the sun's rays which are able to penetrate the skin.The increase in clothes,body fat,the use of sunscreen and our overall fear of the sun has led to epidemic levels of clinically low Vitamin D(25-hydroxyvitamin D)circulating in the blood of the average individual,with numbers increasing only slightly in the summer months and falling again over the winter.
It is estimated that over a billion individuals worldwide are deficient in Vitamin D,making it a major medical health problem globally.
Part of the problem lies in the reduced exposure to adequate UVB,which is often unavailable in many regions,except for a noticeably short amount of the year.Other complications which limit exposure to Vitamin D producing solar light is overcrowded cities and polluted skies,which block the necessary UVB rays needed to create Vitamin D from cholesterol in the skin.
这个问题的部分原因在于缺乏足够的 UVB，许多地区往往没有这样的机会，除非一年中有明显的短暂时间。其他限制暴露在产生维生素D的太阳光下的并发症是城市过度拥挤和受到污染的天空，它们阻挡了从皮肤胆固醇中产生维生素D所必需的 UVB 射线。
The fat-soluble essential vitamin,25 hydroxyvitamin D,is necessary for proper bone mineralization,support of most metabolic functions,neuromuscular health and immune modulation.
This increase in Vitamin D production is supposed to be,in part,responsible for the decrease in viral illnesses during the summer months when the sun's solar rays are more intense,and more people spend time outdoors in less clothes.
So,while uncoupled from the more prolific red-and-infrared spectrum of full solar radiation,high-energy short-wave UV can easily become damaging to the human body,but its overall benefits to the health of our organism is inarguable when used responsibly.
So why,over the past century,has much of the messaging concerning the sun revolved around the dangers of excessive sun exposure and not its benefits?
The effects of UVA radiation which penetrates deep into the skin tissue can,when used inappropriately,can lead to cancer indirectly through the production of harmful molecules like ROS(reactive oxygen species)that deleteriously affect DNA or through the more direct damage done to DNA broken by UVB radiation,which is more commonly known to be responsible for sunburns,the breakdown of collagen,skin aging and the heightened risk of skin cancers.
长波紫外线辐射渗透到皮肤组织的深处，如果使用不当，可以通过有害分子的产生间接导致癌症，比如有害地影响 DNA 的 ROS(活性氧类)，或者通过长波紫外线辐射对 DNA 造成更直接的损伤，而长波紫外线辐射通常被认为是导致晒伤、胶原蛋白分解、皮肤老化和皮肤癌风险增加的原因。
But,while the WHO(World Health Organization)has declared the Sun,or more specifically'solar radiation,'to be a group 1 carcinogen,they also acknowledge that lack of sun exposure is responsible for far more death and disease overall.Evidence strongly suggests that adequate amounts of Vitamin D3 are unable to be gotten though dietary means,leaving responsible exposure to the sun the best way to increase needed Vitamin D stores.
Still,with the prolific warnings to avoid the dangers of the sun screaming at us from bottles of sunscreen and lotions,commercials,medical websites and posters for more than half a century,it's no wonder we eventually stopped questioning the message and,in large part,accepted the idea that nature was attempting to kill us through her thermal light.
Eventually many of us went inside our tightly-constructed homes,flipped on our cost-efficient LEDs,turned on our televisions,scrolled through our smart devices and avoided the obvious hazards which lurked just outside,happily safe from the sun and bathed in the comforting blue glow of technology.
最终，我们中的许多人走进了自己紧密结构的房屋，打开了节省成本的 led 灯，打开了电视，滚动着我们的智能设备，避开了外面潜伏着的明显的危险，愉快地远离阳光，沐浴在令人舒适的蓝色科技光芒中。
But not all light is created equal,and some scientists are now worried at the amount of time people spend exposed to non-thermal light sources.
Appearances can be deceiving and while we perceive the combination of the colored light waves in the solar spectrum to be a white light,it's really a combination of distinct colored light waves with varying lengths containing energy in the visible spectrum that scientists say ranges from 380 Nanometers at the blue end to approximately 780 nanometers at the red end.
"Blue"light,which makes up approximately one third of the visible light spectrum,is a short high-energy visible(HEV)wave.
It is also the predominate light wave represented in light-emitting diodes,better known as LEDs.Because they are highly efficient to the tune of decreasing energy requirements as much as 95 percent when compared to the older incandescent thermal light bulbs,LEDs have largely replaced their inefficient counterparts.
它也是发光二极管(led)中占主导地位的光波。因为与老式的白炽热灯泡相比，它们的效率高达95%，因此 led 在很大程度上取代了效率低下的同类灯泡。
This single change to our indoor environments may be far more disruptive than proponents could have appreciated.
While the heat from the old incandescent and halogen bulbs was an infrared that bestowed beneficial health effects and balanced the spectrum of light,the new LED bulbs are a non-native EMF radiation source which some photo biologists are warning can lead to age-related macular degeneration,through damage to photoreceptor cells and mitochondrial dysfunction.
虽然老式白炽灯和卤素灯发出的热量是红外线，可以带来有益的健康效应，平衡光谱，但新型 LED 灯是一种非天然的电磁辐射源，一些照相生物学家警告说，这种辐射源可能会通过损害光感受器细胞和线粒体功能障碍而导致老年黄斑变性。
Because blue light exposure causes overproduction of ROS resulting in oxidative stress,the damage done by excessive exposure to these lights would also necessitate increased regenerative light exposure from the red-and near-infrared spectrum to balance it out,however,little red and no near-infrared is found in the LED spectrum.
由于蓝光照射会导致活性氧过量产生氧化应激，过度暴露于这些光照射造成的损害也需要增加再生光照射的红光和近红外光谱来平衡，然而，在 LED 光谱中几乎没有发现红光和近红外光。
Blue light exposure in the evening,which is common in the average household across the planet,is also responsible for suppressing melatonin production and increasing cortisol,ultimately confusing the biological day and night cycle,your circadian clock.
Melatonin is more than just the hormone instigated by your ganglion cells in your retina and produced in the pineal gland to help you sleep at night.
It is also a free radical scavenger,an antioxidant,an anti-inflammatory and a circadian modulator,among other thing.
Exposure to artificial light sources after the sun has set is linked to a variety of disorders and pathologies including breast cancer,neurological,psychiatric and metabolic disorders.
Researchers have even found that circadian disruption may cause structural changes to the brain,affect moods,decrease neurogenesis,cause impairments in learning and memory and even increase depression.
Interestingly,while white and blue light had a marked negative effect on the hippocampal region of the brain,red light had very little effect,making it a non-threatening light source.
According to Dr.Alexander Wunsch,a respected expert in the field of photobiology,clear incandescent bulbs are preferred for indoor lighting over the newer LEDs as they have a color rendering index equivalent to the sun's,which is 100,and a color temperature that rarely exceeds 3000 kelvin(k).
根据光生物学领域一位受人尊敬的专家 Alexander Wunsch 博士的说法，与新型 led 相比，透明白炽灯泡更适用于室内照明，因为它们的演色性指数相当于太阳的100开尔文，色温很少超过3000开尔文(k)。
By comparison,the sun is at 5,500 kelvin at its center,and natural light is approximately 2700 kelvin,LEDs on the other hand can run as high as 6,500 kelvin,without the thermal component,making them higher in color temperature than the sun,yet deceivingly clear and inviting.
The influence of light over our biology is unquestionable,yet the study into the extent and depth of that influence is still in its infancy.
Humans have adapted and thrived since the beginning of humanity beneath the watchful rays of the sun.Ancestrally we rose with the dawn and we slept when darkness fell,our only light,that of the moon,the stars and perhaps a glowing fire.
With fire lights CRI of 100 and a color temperature of 1900,this glow doesn't affect the natural rise and fall of melatonin,and thus our biological clocks were set by the native rhythms of full spectrum light and the changing seasons which we were intimately connected to all year-round.
当火光的 CRI 值为100，颜色温度为1900时，这种光线不会影响褪黑激素的自然升降，因此我们的生物钟是由全光谱光线的自然节奏和季节变化设定的，我们全年都与这些节奏紧密相连。
Modern life has given us undeniable advantages and innovations,but in the midst of this lies an unfortunate loss,with the severing of our connection to the natural rhythms and while we may be unconscious of the impact of this loss,our cells and our physiology are definitely not.
While this branch of science necessitates mature solutions such as blackout curtains,street lights whose design points its light towards the night sky to prevent leakage of light,LEDs which adjust their wavelength to mimic the progression of the daylight and shift into red after dark,and even glasses that use amber lenses to block the more harmful blue rays from indoor lighting and electronics,will more and more be used to negate damage being done through our constant exposure to light pollution?
For now,perhaps the easiest and best place to start with resetting your circadian clock and increasing your mitochondria's ATP potential is to get out in the early morning sun for a good half hour to an hour,put your feet on the ground around noon and step out into the rays of the UVB rich light and let your body absorb and create plenty of Vitamin D,and then when night falls,put on your blue blocking glasses or eat by candle light and read a book rather than stare at an electronic blue back-lit device.
现在，重新设置你的生物钟，提高你的线粒体 ATP 潜能，最简单也是最好的方法就是在清晨的阳光下呆上半个小时到一个小时，在中午的时候把你的脚放在地上，走到富含 UVB 的光线中，让你的身体吸收并产生大量的维生素D，然后当夜幕降临的时候，戴上你的蓝色遮光眼镜，或者在烛光下吃东西，读一本书，而不是盯着一个蓝色的电子背光设备。
How Our Family has Benefited from Changes in our Routine
While researching this subject,I found myself compelled to make rather large changes in my daily routine,and that of my children.
Understandably,they were not terribly excited when I woke them up at dark o'clock to witness the sun's triumphant return.But with bare feet pressed into the earth beneath their deck chairs,they silently watched the sun peek through the trees and eventually reveal herself completely.
The birds who arrived for their morning worms were as confused as the children by our presence in the yard and watched us suspiciously from the branches above.
But an odd thing happened over the course of the first week,we became addicted to this early morning rise and setting an alarm soon became unnecessary.After a few days,the birds and the squirrels showed up to greet us each morning and became so bold as to practically pull up a chair next to us.
I made it a point to do the majority of my work and the children's work outside in the yard or on our porch in order to be exposed to natural light for the majority of the day,and we also decided to eat by candlelight each night and use red light before bed to help prevent the suppression of our natural melatonin wherever possible.
As a result,we found that we all are sleeping better,have much more mental energy and are overall feeling far more relaxed,even in the midst of this pandemic.
Perhaps,the most life-changing thing you can do right now,given the circumstances,would be to go outside and reset your internal clock,soak up(responsibly)some UVB and infrared rays to boost your immune system and turn off your LEDs after the sun goes down.
也许，在这种情况下，你现在能做的最能改变你生活的事情，就是出去重新设置你的生物钟，吸收(负责任地)一些 UVB 和红外线来增强你的免疫系统，并在日落后关掉你的LEDs灯。
