Experts Warn LED Bulbs May Harm Metabolism and Sleep, Prompting Switch Back to Incandescents

A shift in health trends is seeing some individuals moving away from LED light bulbs, citing potential negative impacts on metabolism, sleep patterns, and even driving safety. This growing concern has prompted a resurgence of interest in incandescent bulbs, with some health influencers and ordinary consumers actively switching back to older lighting technologies. These 'freedom lights,' as some have dubbed them, are being chosen for their perceived health benefits.

One individual, Rachel Mitchell, 48, reported experiencing health issues starting in 2021 after she replaced her home light bulbs with LEDs, acquired a new LED computer monitor, and her husband brought home an LED television. Mitchell has since begun stockpiling incandescent bulbs, searching for old stock or decommissioned industrial bulbs and hunting for them in antique shops.

While scientific understanding is still developing, preliminary research suggests that light wavelengths play a crucial role in human health. Studies have indicated a potential link between low exposure to certain types of light and conditions such as type 2 diabetes, anxiety, skin aging, obesity, and cancer. The long-wavelength light, often associated with incandescent bulbs, is believed by some to be vital for overall well-being.

This movement highlights a growing awareness of how environmental factors, including artificial lighting, might influence health. As more information emerges about the potential effects of different light spectrums, consumers are increasingly scrutinizing the technologies they use daily.
