Many people are converting the lighting in and around their homes from incandescent bulbs to LED ones, in the interest of energy savings and longer bulb life. This seems like a good idea, right? In fact, before making this conversion, we would do well to consider:
LEDs emit high amounts of blue light; they have very little red, and no infrared, light frequencies. The blue light, without the counterbalancing reds, can damage the cells in our eyes.
The red frequencies, missing in LEDs, are important for repair and regeneration of cellular damage.
LED light impedes sleep because it suppresses melatonin production. Regular exposure, especially after sunset, may contribute to worsening of sleep.
LED light negatively affects the mitochondria, the energy-producing components of our cells, impeding production of the energy needed for healthy metabolism.
Incandescent lighting most closely resembles full-spectrum natural sunlight, which is the healthiest for us.
We can make our light environment healthier by using incandescent lighting in areas where we spend the most time---kitchen, office, etc., and only using LEDs in areas such as hallways, closets, garage, etc.
