Sleep deprivation linked to increased hypertension risk

New research highlights the significant link between sleep deprivation and cardiovascular health. A study published in the journal Blood Pressure, which analyzed data from over 15,000 participants aged 65 and older, found that sleeping fewer than six hours per night is associated with an increased risk of hypertension. Interestingly, the study noted that sleeping nine or more hours did not show a significant connection to high blood pressure.

Beyond hypertension, chronic sleep deficiency affects the endocrine system, metabolism, and immunity. The buildup of adenosine in the brain acts as a biological timer for sleep; when sleep is insufficient, this process remains incomplete, leading to increased fatigue and potential disruptions in heart rate and blood flow. While short-term sleep debt can sometimes be recovered, long-term deprivation poses more serious challenges to regulating essential bodily functions.
