Neuroscientist warns common household item is a 'public health emergency'
New York Post • • health
Key Points:
- Neuroscientist Glen Jeffery from University College London warns that energy-efficient LED bulbs may pose a serious public health risk by damaging mitochondria, potentially increasing the risk of diabetes and metabolic disorders.
- Studies cited by Jeffery show that short-wavelength blue light from LEDs can reduce mitochondrial activity and alter metabolism and liver function in mice, suggesting systemic health impacts.
- Jeffery compares the potential health threat of LED lighting to asbestos, emphasizing the need for urgent action, while noting that mitochondrial dysfunction affects blood signaling and overall body health.
- The European Commission’s Scientific Committee (SCHEER) disputes these claims, stating there is no evidence of direct adverse health effects from normal LED use, though they acknowledge possible temporary discomfort and circadian rhythm disruptions.
- Jeffery recommends increasing exposure to near-infrared and broad-spectrum light, such as from incandescent bulbs or natural sunlight, to counteract the negative effects of LED lighting on vision and health.
