Which type of lamp is linked to cancer – doctor's answer
British neuroscientist Glen Jeffery has stated that LED lamps may pose a health threat comparable to asbestos. Animal experiments showed that the blue spectrum of LED lights reduces mitochondrial activity and increases cancer risks. The scientific community is cautious about these findings, noting a lack of convincing evidence for healthy humans.
British neuroscientist Glen Jeffery made a resonant statement, comparing the widespread use of LED lamps to the underestimated danger of asbestos. According to him, the short-wave blue spectrum emitted by LEDs negatively affects mitochondria — the cellular organelles responsible for energy production and metabolism. Experiments on laboratory animals showed that daily exposure to such radiation can reduce mitochondrial activity by nearly half and provoke metabolic disorders, increasing the risks of developing cancer. However, the scientific community is cautious about these conclusions. The official position of the European Commission's Scientific Committee on Health, Environmental and Emerging Risks (SCHEER) indicates a lack of convincing evidence that standard household use of LED lamps can cause direct organic damage in healthy people. Independent experts note that the proven consequence of excessive blue light remains only temporary eye fatigue and disruption of circadian rhythms due to suppressed melatonin production. To minimize potential risks, specialists recommend combining LEDs with traditional incandescent lamps and spending more time in natural daylight.
