Sleep & High Blood Pressure: The Link
- Insufficient sleep may significantly increase the risk of developing high blood pressure, according to research presented at the American College of cardiology's Annual Scientific Session.
- The analysis,encompassing 16 studies conducted from 2000 to 2023,evaluated hypertension incidence in 1,044,035 individuals without prior high blood pressure history.
- Kaveh Hosseini, MD, assistant professor of cardiology at the Tehran Heart Center in Iran and the study's principal investigator, emphasized the importance of adequate sleep for cardiovascular health.
Uncover the critical link between sleep and high blood pressure in a groundbreaking study involving over a million participants. This research reveals a direct correlation: insufficient sleep significantly elevates the risk of developing hypertension, especially for those consistently logging less than seven hours nightly. The risk escalates further with fewer than five hours of sleep. Analyzing data from six countries, the findings shed light on how sleep duration impacts cardiovascular health, with women perhaps facing a higher risk than men. Lifestyle factors and sleep patterns are explored as contributing elements. news Directory 3 brings you the latest insights. Discover what’s next in refining our understanding of sleep’s vital role in preventing hypertension.
Shorter Sleep Linked to Higher Blood Pressure Risk, Study Finds
Updated June 15, 2025
Insufficient sleep may significantly increase the risk of developing high blood pressure, according to research presented at the American College of cardiology’s Annual Scientific Session. The study, analyzing data from over a million people across six countries, found a clear link between short sleep duration and hypertension.
The analysis,encompassing 16 studies conducted from 2000 to 2023,evaluated hypertension incidence in 1,044,035 individuals without prior high blood pressure history. participants were followed for a median of five years. The results indicated that those sleeping less than seven hours nightly faced a higher risk of developing hypertension, even after adjusting for factors like age, sex, and BMI. The risk was even more pronounced for those getting fewer than five hours of sleep.
Kaveh Hosseini, MD, assistant professor of cardiology at the Tehran Heart Center in Iran and the study’s principal investigator, emphasized the importance of adequate sleep for cardiovascular health. “Based on the most updated data, the less you sleep — that is less than seven hours a day — the more likely you will develop high blood pressure in the future,” Hosseini said. “Getting seven to eight hours of sleep, as is recommended by sleep experts, may be the best for your heart too.”
The study revealed a 7% increased risk of high blood pressure for those sleeping under seven hours, escalating to an 11% increase with less than five hours. Hosseini noted that common risk factors like diabetes and smoking elevate hypertension risk by at least 20%.
while the study didn’t pinpoint the exact cause, Hosseini suggested disrupted sleep patterns could be a factor. Lifestyle habits, such as overeating and alcohol use, and conditions like anxiety, depression, and sleep apnea, may contribute.
Interestingly, the association between sleep duration and hypertension remained consistent across age groups. However, women reporting less than seven hours of sleep showed a 7% greater risk of developing high blood pressure compared to men.
“Getting too little sleep appears to be riskier in females,” Hosseini said. “The difference is statistically significant, tho we are not sure it’s clinically significant and should be further studied. What we do see is that lack of good sleep patterns may increase the risk of high blood pressure, which we know can set the stage for heart disease and stroke.”
Experts recommend discussing sleep patterns with health care providers, especially if experiencing disrupted sleep or symptoms of obstructive sleep apnea, a condition linked to increased risks of hypertension, stroke, and coronary artery disease.Addressing sleep duration and quality is crucial for managing hypertension risk and promoting overall cardiovascular health.
What’s next
Hosseini called for further research using more precise sleep evaluation methods to solidify these findings. He also stressed the need for standardized definitions in sleep research to ensure comparability across studies. Future studies should focus on the role of sleep duration and sleep quality in hypertension prevention.
