Flinders University study links regular sleep to lower blood pressure risk

A study published in the Journal of Sleep Research, the journal of the European Sleep Research Society, has identified a significant link between consistent sleep schedules and a reduced risk of high blood pressure. Researchers from the Flinders University Health and Medical Research Institute analyzed sleep data from 95,819 participants across more than 30 countries over a 20-month period.

The findings indicate that individuals who maintain a regular sleep schedule face up to a 46% lower risk of developing high blood pressure compared to those with irregular sleep patterns. Participants classified as having “irregular” sleep were defined by variations in sleep duration of 90 minutes or more and shifts in their sleep midpoint of 60 minutes or more.

Additionally, those with regular sleep patterns experienced approximately 40 minutes less time spent awake during the night. The study also noted that irregular sleep habits can become persistent; individuals maintaining irregular patterns for six months faced an 80% higher likelihood of continuing those habits. Researchers suggest that constant changes in sleep and wake times force the circadian rhythm to continuously adjust, leading to long-term health impacts.
