[Diurnal rhythms of blood pressure in night shift workers].

Studies involved various methods of averaged diurnal (circadian) changes of blood pressure in night shift workers and proved that blood pressure is lower during the night shifts, than in the day ones. But this decrease is insignificant and does not reach the level in night sleepers. Diurnal blood pressure profile averaged for large mass of night shift workers (for all hours during the work) could be assigned to non-dippers, i.e. insufficient night decrease of blood pressure, especially of dyastolic pressure. Insufficient decrease of blood pressure during the night shift could be estimated as unfavorable for health. From the other hand, some blood pressure decrease during the night shift could decrease the work quality.
