Doctor Warns: LEDs Harm Cells Like Asbestos
3 Dec
Summary
- LED light's blue spike impacts mitochondrial cell function.
- Mice studies showed LED exposure caused cell decline and weight gain.
- LEDs suppress melatonin, disrupting sleep and potentially causing chronic issues.
Dr. Glen Jeffery, a neuroscience professor at University College London, has issued a stark warning regarding the widespread use of LED bulbs in homes, likening the issue to a public health emergency comparable to asbestos. His research highlights that while certain natural light spectrums benefit bodily functions, the high blue light emission from LEDs can significantly harm mitochondrial health.
Experiments involving mice exposed to LED lighting demonstrated a decline in mitochondrial responsiveness and significant weight gain over a week. This cellular impact is concerning, as healthy mitochondria are crucial for energy levels and rapid recovery from illness. The suppression of melatonin, a key sleep hormone, by LED light is also a significant concern.
Beyond human health, light pollution from LEDs detrimentally affects invertebrates, potentially reducing populations. Experts advocate for better quality, lower-level lighting that is more harmonious with the natural world, which could also lead to energy savings and a safer environment for all species.
