Researchers found a concerning link between irregular sleep patterns and high blood pressure, also known as hypertension.
In their large-scale study, published in the peer-reviewed journal Hypertension, a team of researchers analysed sleep data from over 12,000 adults around the world, shedding light on how inconsistent sleep schedules can negatively impact our heart health.
How Does Irregular Sleep Affect Your Blood Pressure?
The study found that irregular sleep duration and inconsistent bedtimes are associated with a higher risk of developing hypertension. Participants who had more variability in their sleep schedules were more likely to have elevated blood pressure levels.
For example:
A 34-minute variation in the time participants fell asleep was linked to a 32% increase in the likelihood of having high blood pressure.
Similar patterns were observed with variations in sleep midpoint and wake-up times.
These findings suggest that not only how much sleep you get but also the regularity of your sleep schedule is crucial for maintaining healthy blood pressure levels.

Who Is Most at Risk?
The study primarily looked at middle-aged adults, with an average age of 50 and the majority of the participants were men. Overweight individuals also showed a higher prevalence of hypertension linked to irregular sleep patterns. However, these insights are relevant for everyone, emphasizing the importance of maintaining a consistent sleep schedule.
What the Research Tells Us
The researchers used under-mattress devices to monitor sleep patterns and blood pressure over several months. This approach provided detailed and long-term insights into how sleep irregularity can affect cardiovascular health.
By understanding the impact of sleep patterns on health, this study highlights the importance of regular sleep schedules as a potentially modifiable risk factor for hypertension. These findings could lead to new recommendations for improving heart health through better sleep practices.
