Recently, Mr R was spending a holiday afternoon at home, rearranging the setting of his lounge with a couple of man-servants, when a small accident took place. A large bag had dropped to the floor and something inside seemed to have broken. With great trepidation, Mr R stepped forward hoping against hope, to disconfirm his fear. There it was. A broken energy-saver. And then, to the great amusement of his man-servants, Mr R was fleeing.
Most of us in Pakistan tend to think of light-bulbs as something of a monolith. Initially, they were the warm, orange-light emitting bulbs that would fuse eventually, and then in the last decade ostensibly newer ‘variations’ emerged with energy-saving potential, funky designs and long-lasting life-spans.
Of the newer varieties, most of us prefer the ‘warm-white’ type (which the aesthetically-motivated of us are suspicious isn’t quite the same thing as the original) and don’t like so much the ‘cool daylight’ ones.
Let’s recap. There are actually two types of light-bulbs: there is the original incandescent bulb that Thomas Edison invented with the wonderful orange glow we all grew up with, and then there are the newer energy-saving ‘CFLs’ — compact fluorescent lights — which are actually based on the same technology that tube-lights use. And, according to a publication by light researcher Michaele Wynn-Jones in The Guardian, these CFLs should carry a visible health warning. That’s because fluorescent technology wreaks havoc on the psychophysiology of living organisms to such an extent that Wynn-Jones identifies their use with the (previously) unexplained rise of suicide cases in prisons in the UK.
According to Wynn-Jones, some fluorescent bulbs can cause depletion of key neuro-chemicals in humans, such as serotonin and melatonin. Newer research validates this claim while also showing that exposure to the ‘cool daylight’ type will also serve to increase heart rate and body temperature. This has two effects:
• Constant exposure to CFLs, particularly at the expense of sunlight, can precipitate a type of depression known as ‘Seasonal Affective Disorder’, commonly referred to as ‘winter blues’
• It can completely halt and even reverse the physiological changes that are responsible for inducing sleep, instead giving your body what a study in the Psychiatric Hospital of the University of Basel identifies as comparable to a dose of caffeine.
Thus, bulbs are legally banned in hospitals in Germany.
But that is not the half of it. In the midst of a raging debate in the US that has manifested in a government divide, an article in MSN health identifies that the supposedly insignificant amount of mercury, which is known to cause brain and kidney damage, inside all CFLs is enough to “contaminate upto 6,000 gallons of water.” In fact, the procedure outlined by the Environmental Protection Agency to eliminate a broken CFL is so precarious and exhaustive that people in the US rely on special cleaning services to come in and dispose off the bulb in a picture that resembles “the site of a hazardous material accident” — breathing apparatus, air-tight plastic seals and all!
Former hopeful for the US 2012 presidential elections Michele Bachmann famously vowed to remove all CFLs from the White House.
Other research of interest:
• Under fluorescent lighting, one’s evaluation of the immediate space has been demonstrated to ‘evoke a negative response pattern.’ Ask someone to rate a work of art underneath sunlight, and then do the same under artificial lighting, particularly ‘cool daylight.’ The response is dismal and this doesn’t exclude interpersonal evaluations!
• The nutritional quality of foods, such as olive oil, has been shown to deteriorate significantly when stored underneath fluorescent lighting.
• Visual discomfort is greatly increased and there is preliminary evidence to indicate that the inherent flicker in fluorescent lighting can be a causal factor for people who read extensively underneath artificial lighting to develop early cases of ‘presbyopia’ or ‘farsightedness.’
Energy-savers have a dark side. And for the many of us headed back home on the canal with the new CFLs installed, not surprisingly a few seconds later into the night every day, we are right in the midst of it.
