Persistent insomnia (difficulty initiating or maintaining sleep) significantly increases the risk of developing hypertension in middle-aged male workers, independent of age, BMI, smoking, alcohol, and job stress.

If you consistently struggle to fall asleep or stay asleep, treat it as a serious health risk, not just an annoyance. This study shows that persistent sleep problems nearly double your risk of developing high blood pressure, even if you are healthy in other ways. Prioritize sleep hygiene and seek medical evaluation for chronic insomnia to protect your heart.

After adjusting for potential confounding factors (i.e. age, body mass index, smoking, alcohol drinking, and job stress), persistent complaints of DIS and DMS were significantly associated with an increased risk of hypertension (OR=1.96; 95%CI: 1.42–2.70 and OR=1.88; 95%CI: 1.45–2.45, respectively).
