Birds and animals can be confused by artificial lighting, leading them away from familiar foraging areas and disrupting their breeding cycles. And the photosynthetic cycles of deciduous trees (those that shed their leaves in the fall) have been shown to be disrupted due to the preponderance of artificial nighttime lightsTurning off unnecessary lights to conserve energy, is not only good for the environment, but it could be good for your health too! Thanks for sharing this information. The public understands many of the causes of breast cancer, but I am surprised when I speak of how few people know about light at night and breast cancer. Women who work night shifts have an elevated risk of breast cancer, but the reverse is also true. Completely blind women have a very low risk of developing breast cancer. The spectrum of light (blue light) is important, and even a bathroom light at night can pose a problem. Most night lights, however, appear to be safe. Lynne Eldridge M.D. Author, "Avoiding Cancer One Day At A Time: Practical Advice for Preventing Cancer" http://www.avoidcancernow.com Good clip. Hmmm. I'd consider this a THEORY unless you have a chance to look at the actual study and/or have such a correlation confirmed by other research. I mean, it SOUNDS true, and it seems believable, but that doesn't make it true. (Correlating something specific like nighttime light exposure to something like breast cancer is inherently problematic, given the billions of other possible factors...) This clip was featured on today's Clipiversity video podcast. It's incredible to learn how messing with our sleep cycles can have more effects on our health than we realize. Proud Mum of the clip am I... thanks guys!  Light keeps you awake and can disrupt sleeping patterns, but I wonder how many "night people", and city dwellers, have Vitamin D deficiency due to inadequate exposure to sunlight. Unnatural light may help us see in the dark, but sunlight has become an essential part of our body's ability to maintain it's self. Artificial light can be cold and depressing in comparison. It's just a shame we need them everywhere, because we are afraid of our own shadows. The physical aspects are one thing, another thing which is harder to pinpoint are the psychological effects. Sleep deprivation can really screw your mind, there is no reason that it would not have a detrimental on physical processes such as our... |
