A study published today in the European Journal of Preventive Cardiology found a link between insomnia and poor cardiovascular health.
Miss He said: “We found that difficulty initiating sleep, difficulty maintaining sleep, or non-restorative sleep were associated with 27%, 11%, and 18% higher risks of cardiovascular and stroke events, respectively.”
“The underlying mechanisms for these links are not completely understood,” continued Miss He. “Previous studies have shown that insomnia may change metabolism and endocrine function, increase sympathetic activation, raise blood pressure, and elevate levels of proinflammatory and inflammatory cytokines – all of which are risk factors for cardiovascular disease and stroke.”
Women with insomnia symptoms had a slightly higher risk of cardiovascular and stroke events than men, especially for non-restorative sleep, but the difference between sexes did not reach statistical significance.
