Title Jumping Spiders Use Image Defocusing For Depth Perception

 

The experiment was one of those experiments that is elegant in its simplicity. When using just green light to illuminate prey, the spiders were always accurate in their strikes, just light in full spectrum light. However, when green light was excluded and red light exclusively was used to illuminate prey, the spiders attacks on prey were typically short.

Comments: While nominally about how spiders hunt, we were interested in this article for the information contained on how the eyes of one particular species have evolved to take advantage of different spectrum within the light we see and how they are disadvantaged when even one colour is removed from their available light spectrum. And to think we see all those options as simply white.

Title Seasonal Vinyasa Yoga for Winter

 

The main intention behind my winter seasonal vinyasa practices is to help you ward off typical Kapha imbalances by raising your core temperature, enhancing your metabolism, and increasing your circulation and spirit by offering you dynamic, invigorating, rhythmic sequences that keep the earth and water from going out of balance.

 

 

Also, try eating less to keep your digestive fire bright, supplementing your diet with vitamin D, omitting sugar and alcohol to reduce mood swings, enjoying a hot bath, sitting by a fire, or spending five to ten minutes in a tanning bed or in front of full-spectrum light bulbs. These are just a few alternative ways to move you towards sukkha, and away from suffering, or dukkha, during this dark season.

Comments: This author covers more than just the practice of the asanas (exercises) in how yoga can be incorporated into your life. We are especially interested in the discussion of how light is incorporated into a yoga practice over winter.

Do you feel like you’re out of sync? Here are some tips to help get your rhythm back…

 

Tip 3: Make sure you get natural light. Just as we need darkness to support our sleep cycles, we need light — particularly morning sun- for our day cycles. We need the light of the sun to trigger our metabolism, alertness and overall ability to function and perform. And if you spend most of your day indoors, replace your artificial or fluorescent lights with full-spectrum light bulbs.

Title Illuminating the biological basis of light therapy

 

Light therapy has been of medical interest for centuries and many pre-modern hospitals included a solar room for patients. However, only in recent decades is the physiochemical basis of light’s effects on mammals beginning to be understood. Here, we will explore an example of how light affects a biochemical process important for mood and sleep-wake cycles. In doing so, we can gain insight as to how non-light mood enhancers may work through a similar mechanism.

Comments: This article is an indepth look at the concept of light and what research shows about its effects on us. For those who are interested in the field, this is well-worth reading./i>

My New Studio

 

Whoopie!!!! I’ve just completed moving all my art supplies from our dining room, living room, and spare bed room into my newly renovated basement. The first photo is the finished painted concrete floor. I chose to go this route because having had wall to wall in the past it seemed to be the best choice per reference articles on basement studios. Note the reflective quality which aids in keeping the space bright. I’ve opted instead to lay down smaller area rugs for warmth.

 

The task lighting is using full spectrum light bulbs and the walls are very light grey so as to not cast any colors onto my work.

Comments: We love reading about people’s lighting design plans. In this case, as an artist, the writer had quite specialised lighting needs. We’re pleased to see that full-spectrum lighting was able to give them what they needed.

What Makes Us Happy

What Makes Us Happy

 

This premise, that humanity has evolved for million of years to live in, thrive in, and enjoy a specific environment (notably the warm, sunny climate of sub-Saharan Africa), logically assumes that when people begin to replicate their instinctive behavior in things like diet (Mostly meat, nuts, and some vegetables) and lifestyle (Active and sun drenched), their happiness should rise as their genetic makeup begins to resonate with their lifestyle.

Comments: Many of the articles discussing light and how you feel, come at the topic from the point of view of treating sadness or seasonal affective disorder. This article however is about how light is one of the elements that take us from regular living to happiness. Worth a read to get their insight into the conditions required for happiness.

How to: Have a Happier Winter

How to: Have a Happier Winter

 

With the holidays over and Spring break months away, the winter may seem like a long unnecessary cycle of overcast skies and frigid temperatures.

 

A combination of shorter days, less sunlight, and cold temperatures may cause heightened feelings of depression and sadness during the winter months. However there are several things you can do to improve your mood and make the winter more bearable.

 

Get Some (fake) Sun: While there may seem to be a shortage of sunny days during Michigan winters, take advantage of them and get outdoors. Sunlight releases neurotransmitters in the brain that improve mood. Enjoy the benefits of sunlight even on overcast days by using full spectrum light bulbs, which have been shown to ‘mimic natural sunlight.’

Comments: For those living in the Northern hemisphere we are starting to see the peak of published material on how to deal with Seasonal Affective Disorder. This article (from a secondary school paper) has a good down-to-earth list of solutions for those suffering from SAD this year.

How important are light fixtures in schools

How important are light fixtures in schools

 

Anecdotal evidence still suggests that “warmer” light (associated with incandescent and fire-light) is easier on the eyes, and full-spectrum products can make black print easier to see on white paper.

Read more.

 

Comments: This article refers to a recent decision by a local school to invest in lighting that while more expensive in the short-term, has long-term energy savings and cost savings. The lights chosen are also rated by teachers as being “warmer” and better for reading. We applaud any organisation that is prepared to look after their people in this manner and trust that more schools start thinking in this manner.

Stop Flirting & Commit : Rules of Engagement With Colour

 

Just as with any budding attraction, should you bring it home with you, you might be surprised how it looks like in a different light. Colours which look great on the colour chart under fluorescent lighting in the paint store will look much different at home in a sunny room or lit by incandescent lighting. Tungsten bulbs give a slightly yellow light; halogen gives white light, while some fluorescent bulbs can give flat, cold light. All these lights can all affect how the colour looks. Your best bet is full spectrum lighting, which mimics daylight, to show a colour at its’ best.

Comments: In this long(ish) post, the authors advise on ways in to include colour in your home design choices. In terms of making your colour decisions, the best piece of advice they give, is to make sure you’re looking at it under the right light.

Aiming for an employee-friendly office environment

 

To begin with try to go for an office with decent windows and light-coloured paint – as being stuck for hours in dark, drab surroundings will lower anyone’s morale. There is also the option of full-spectrum light bulbs, which effectively simulate the feel of natural light – ideal for brightening offices during the dreary winter months.

Comments: When looking after our health, the time we spend in office work each day is often forgotten time. We applaud the writers of this article for thinking of the role that light plays in looking after workers health and well-being.
