How Nighttime Light, Diet, and Gut Bacteria Rhythms Together Affect Shift Work and Body Clock Disruption

Circadian rhythm disruption is associated with a wide range of adverse health outcomes in shift workers.

• Disruption of circadian rhythms may lead to metabolic, immune, cardiovascular, and neurobehavioral impairments.
• Nighttime exposure to artificial light and irregular eating patterns could affect gut microbial composition and functions.
• Circadian misalignment is linked to gut dysbiosis, inflammation, and metabolic dysfunction.
• Emerging strategies such as chrononutrition and light modulation may help address these issues.
• Targeted microbial interventions, like probiotics, are being explored as potential solutions.
