40 Hz Light Flicker, Circadian Rhythm, and Metabolic Research
Researchers explored how exposure to rhythmic 40 Hz light relates to daily biological cycles and metabolism. In this study, animals given alcohol to disrupt normal patterns of rest and liver function were later exposed to gentle, non-invasive 40 Hz light flicker.
The research observed that 40 Hz stimulation was associated with steadier activity cycles and healthier lipid balance. These effects were linked to changes in SIRT1, a protein involved in regulating the body’s internal clock and energy use. Findings suggest that rhythmic 40 Hz light may play a supportive role in maintaining natural circadian and metabolic rhythms.
