From a Stanford Medicine online release:
In a study published online Sept. 10 in the American Journal of Lifestyle Medicine, Hamidi, along with other Stanford researchers, examined survey results on sleep and nutrition from 245 Stanford physicians and found that a better diet is associated with reduced side effects of sleep deprivation.
Physicians face significant barriers to eating well at work due to long hours, a heavy workload and limited access to healthy meals, snacks and drinks. The findings of this study suggest that by providing healthy options at work, employers could help reduce the brain fogginess, difficulty concentrating and irritability caused by poor sleep among health care providers. And, as a result, help improve patient care.
“Potential mechanisms for the effect of diet on cognitive performance include regulation of hormones, neurotransmitters, and blood flow as well as reduction of oxidative stress and inflammation. The effects of diet on sleep quality have been attributed to the role of dietary factors in regulation of peripheral circadian clocks and to the synthesis of hormones and neurotransmitters that are involved in sleep regulation.”
