New research suggests that limiting food intake to daytime hours may help mitigate cardiovascular risk factors associated with simulated night shift work, even with circadian misalignment. A randomized controlled trial found that daytime-only eating prevented changes in heart rate variability and prothrombotic markers under simulated night work conditions. The study could provide evidence that a daytime eating schedule may offset some adverse cardiovascular effects of circadian misalignment, benefiting individuals engaged in night shift work and potentially reducing coronary heart disease risk.
