Why the study?
Does night shift work alter circadian blood pressure and heart rate rhythms in normotensive shift workers?
Does night shift work alter circadian blood pressure and heart rate rhythms in normotensive shift workers?
Night shift work rapidly reverses the normal circadian blood pressure rhythm, aligning it with the altered sleep-wakefulness cycle.

May prompt BP monitoring in new night shift workers; extends circadian data but leaves open CV risk implications.
The blood pressure and heart rates of seven normotensive shift workers were monitored automatically for 24 h with a non-invasive ambulatory method on 3 different days. The first monitoring session took place at the end of an ordinary work period of morning shifts, the second on the first day of a period of night shifts, and the third on the last day of a period of night shifts. The circadian blood pressure rhythm, which showed a normal pattern during the daytime work shift, was totally reversed from the first day of the night shift. The blood pressure rhythm closely followed the sleep-wakefulness cycle. The changes in circadian heart rate rhythm were not as pronounced as those in blood pressure but showed a similar trend.
