A study published in&nbsp;Proceedings of the National Academy of Sciences of the United States of America&nbsp;found that&nbsp;working the night shift increases the&nbsp;risk of&nbsp;metabolic disorders, as well as&nbsp;cancer,&nbsp;obesity, stroke,&nbsp;and heart disease.&nbsp;Researchers&nbsp;evaluated the impact of misaligned sleep/wake and feeding/fasting cycles on circulating metabolites&nbsp;in 14 patients. They&nbsp;obtained&nbsp;sequential plasma samples&nbsp;of 132 circulating metabolites&nbsp;during a 24-hour&nbsp;constant routine that followed a 3-day&nbsp;simulated night-shift schedule&nbsp;(n=7)&nbsp;compared with a simulated day-shift schedule&nbsp;(n=7).&nbsp;<blockquote class="twitter-tweet" data-width="500" data-dnt="true">
