Light Therapy for Happiness
Bet you never knew that light could change the way you felt about things. It’s a scientifically proven fact; light affects the release of hormones in your body, mainly those that control your sleep-wake cycle, which is why it’s a lot easier to fall asleep with the lights off.
More importantly, light can also have some bearing on your mood. In fact, lack of regular exposure to sunlight has been known to lead to seasonal affective disorder, a condition characterized by depression and mood swings. It is also linked to why many suicides take place in the winter months, when people tend to be cooped up indoors.
Experts have recommended exposure to special kinds of light for individuals suffering from depression and other mood disorders. It’s actually quite convenient; all it takes is for you to sit under a lamp for a certain period of time each day. It’s called light therapy, and it sure beats having to take a multitude of drugs that leave you with unpleasant side effects.
It’s possible to chase away those annoying blues by simply changing your level of exposure to light. Sunlight is always the preferred kind of lighting, but that’s not always a feasible option all year round. This is why special light bulbs are used to mimic the same positive effects that sunlight has in restoring the body’s natural hormonal balance and circadian rhythms. Scientists have identified certain photo receptors in the human eye that allow you to recognize and respond to light.
As you already know, this contributes significantly to one’s mood. The photo receptors trigger the hypothalamus, which nudges the pineal gland to start producing serotonin, which is a hormone that renders you more energetic and alert. Without serotonin, you’d be curled up in the blankets thinking it would be better if you’d just slept the day away in bed, and hypersomnia does not a happy camper make.
Ensure that these light bulbs are exactly the right type, because depression and SAD respond better to a specific wavelength, which you can’t exactly find in an ordinary incandescent light bulb. You can even get a prescription from a doctor, to be absolutely sure. If you don’t have access to sunlight, stay in bright places and think happy thoughts. It may be snowing out, but at least you don’t have to be gloomy on the inside as well.

What's Hot: Aged Brass w/Matte finishes
They said brass was dead. Over and over this was the cry in the lighting world. People felt shame over their shiny brass fixtures and went running to more exotic (read; non-brass) finishes like satin nickel, rubbed bronze, brushed pewter, oil-rubbed bronze, satin this, or Tuscan that, & on and on.
I have some good news for those of you who never gave up on the allure of brass. IT'S BACK with a vengeance. Maybe not exactly as you remember it, but it's definitely back. This is a great example of rediscovering a classic, and giving it a modern signature. Today's brass is aged & weathered, like it's been through something. That makes sense, because it HAS been through something... namely years of neglect from lighting showrooms coast to coast. Who's laughing now?
Hello, my name is Cody, and I am a reformed design junkie who likes to work strange hours. Sound familiar? Yeah, that's par for the course for many of my colleagues. I chat with my peers on a weekly basis.
Recently, at a coffee shop you haven't heard of (just kidding - it was through text messages), I proclaimed the Lift Bridge to be the best standing desk for graphic designers. After such a proclamation, I wrote this brief list of TWO things that make it a great fit for graphic designers.
Flowers are great. They liven up a room with color, show love, and look good in certain spaces. This is about more than just flowers though.
Get the ambiance right with ambient light...
Ambient light is the most pleasing, in that it’s soft, even, and easy on the eyes. Ambient light helps fill a space with a warmth, and an at home feel you’ll want to set the tone for any romantic evening.
