The association between sleep disturbances and blood pressure variability: a review of the literature

Sleep disturbances are associated with short-term, midterm, and long-term BPV. RLS, shift work, insomnia, short sleep, long sleep, OSA, and sleep deprivation were all positively associated with SBP or DBP fluctuations. The most suggested mechanism behind the relation between sleep disorders and BPV is the increase in sympathetic nervous system activity. Given the prognostic implications of BPV and of sleep disorders on cardiovascular mortality, recognizing and treating these entities is essential as their association could lead to potentiation of worse outcomes. There remain significant gaps in the literature on the topic of sleep and BPV. Future research should focus on standardizing BPV measurements to reach a uniform definition. More research is also needed to examine the impact of sleep disorders treatment on BPV and cardiovascular mortality.
