People who sleep little or poorly are at risk for heart attack or stroke. On the contrary, those who devote 7-8 hours of quality sleep every day have a significantly lower risk of heart attacks and strokes. Czech cardiologists draw attention to the link between sleep and heart disease.
The Czech experts draw on both their own long-term experience and the results of the latest French study, The Paris Prospective Study III (PPS3). “The study clearly proved what we had suspected for years. Those who sleep well, long enough, and ideally before midnight, have a significantly lower risk of developing cardiovascular disease and stroke.” says the chairman of the Czech Society of Cardiology, prof. MD Alesh Linhart, DrSc.
The study involved 7200 healthy people aged 50 to 75 years for 10 years. Study participants first underwent a physical examition and completed questionires about lifestyle, persol and family history, health status, and provided information on five key sleep habits. ATThe researchers alyzed the relationship between sleep quality and cardiac events by taking into account other factors such as age, gender, occupation, smoking, weight, or a family history of heart attack, stroke, or sudden cardiac death.
“Morning Birds” is better
The people in the study were tested every 2 years for 10 years. “French colleagues found out from the very beginning that only 10% of people sleep optimally. In the first eight years, 274 participants developed corory heart disease or stroke.” introduces the results of prof. Linhart. “Those who slept well had a 75% lower risk of heart attack and other heart disease and stroke than those who slept very, very poorly.”
According to Czech cardiologists, young children need to be taught to sleep well so that they carry this habit into adulthood. “Sleep is the most important mechanism for regenerating the body, setting up and maintaining an optimal regimen not only for the cardiovascular system, but also for key metabolic processes in the body. Sleep quality has a big impact on longevity and health.” explains doctor cardiologist. MD Tomasz Kara, Ph.D.
The pressure is rising, the adreline is surging
“If sleep does not have sufficient duration and depth, the heart rate increases, blood pressure rises, adreline is released, various heart diseases can develop, including, for example, hypertension or arrhythmias, starting from early childhood. The risk of developing diabetes or developing atherosclerosis also increases significantly, which further increases the risk of developing serious diseases such as myocardial infarction or stroke.”
Sleep apnea is life threatening
The doctor also draws attention to an often undiagnosed sleep disorder – the so-called sleep apnea, in which breathing sometimes stops during sleep. Thus, the blood is less oxygeted, which is harmful to the heart and blood vessels. “In our experience, half of our patients suffer from unrecognized and therefore untreated sleep apnea, a third of them in a clinically significant form.” delivered the doc. Basket.
Keep a regular schedule
Cardiologists are urging the public not to underestimate sleep hygiene. According to doc. It is good to go to sleep and wake up at about the same time, do not watch TV, use a computer or mobile phone at least an hour before falling asleep, reduce daytime stress and night noise. Movement is also good for sleep, but not before bed. It is good to calm down in general, for example, by reading, talking with loved ones, listening to soothing music, or meditating.
