Understanding Circadian Health and Light's Impact
Light plays a crucial role in regulating circadian rhythms, which are essential for maintaining overall health. Dr. Martin Moreed, a leading expert in circadian biology, highlights how artificial light, particularly blue wavelengths emitted by common LEDs, disrupts these natural rhythms, especially at night. This disruption can lead to various health issues, including obesity and sleep disorders, by signaling to the body that it is still daytime when it should be preparing for sleep. Awareness of the types of light we are exposed to is vital for synchronizing our internal clocks and promoting better health outcomes.
