Increasing the use of LED bulbs is dangerous to health

Exeter: While most countries are using low-energy LEDs, past research has ignored light pollution. A new study has warned that the increased use of artificial blue light could negatively affect human health and the environment. The research said that satellite data in previous studies showed the appropriate balance between blue, green, and red light wavelengths. Did not discriminate. Referring to the data, the scientists said that a large-scale spectral shift was found in the artificial light. This artificial light ranges from high-pressure sodium lights to white LEDs that emit large amounts of blue light.

Previous studies have shown that long-term exposure to blue light is associated with harmful effects on several human cells that accelerate human aging. The scientists cited previous research that I was told about the effects of artificial light at night on the hormone melatonin (the hormone associated with the sleep cycle). That is, the trend toward increased use of artificial light may increase the risks of large-scale harmful effects.
