There are processes tied to the master biological clock in our brain that are saying that day is day and night is night and other processes that follow rhythms set elsewhere in the body that say night is day and day is night. When internal rhythms are dysregulated, you have this enduring stress in your system that we believe has long-term health consequences.
Blood samples drawn at regular intervals throughout the 24-hour period were analyzed to identify proteins present in blood-based immune system cells. Some proteins had rhythms closely tied to the master biological clock, which keeps the body on a 24-hour rhythm. The master clock is resilient to altered shift schedules, so these protein rhythms didn't change much in response to the night shift schedule.
Looking more closely at proteins involved in glucose regulation, the researchers observed a nearly complete reversal of glucose rhythms in night shift participants. They also found that processes involved in insulin production and sensitivity, which normally work together to keep glucose levels within a healthy range, were no longer synchronized in night shift participants.

Scope of maternal substance use disorder crisis is dramatically underestimated, says studyDrug overdoses are a leading cause of maternal mortality in the United States, which has the highest maternal mortality rate of all high-income nations. And despite this convergence of the maternal mortality and overdose crises, substance use during pregnancy has traditionally only been tracked during the hospital visits when babies are delivered.
