Jarida la Journal of the American Heart Association limechapisha Utafiti unaoonesha Watu wenye miaka kuanzia 30 wasio na ratiba nzuri ya Kulala au Kupumzika Usiku, wanakuwa kwenye hatari mara 1.4 zaidi ya kupata matatizo ya Moyo.
Utafiti umeonesha zaidi ya 80% ya Matatizo ya Moyo ikiwemo Mshtuko wa Moyo, Midundo isiyo ya Kawaida ya Moyo, na Ugonjwa wa Mishipa ya Moyo, yanaweza kuzuiwa kwa kubadili Mtindo wa Maisha ikiwa ni pamoja na Utaratibu mzuri wa Kulala ili kuupa Moyo Afya Bora.
Matokeo ya Utafiti licha ya Ulaji Usiofaa kuchangia madhara ya Afya ya Moyo, Watu wenye Utaratibu na Muda Mzuri wa kulala, wanapunguza kwa kiasi kikubwa hatari ya kupata mashambulio yanayoathiri Afya ya Moyo.

Sleep isn’t just a way to pass the time. It’s essential to health, right through to your heart.

This June, the American Heart Association (AHA) added sleep to its heart health checklist, now an 8-item list created to help people reflect on and improve lifestyle habits.
"Sleep is taking its rightful place as a significant risk factor for cardiovascular disease,” says behavioral scientist Brooke Aggarwal, EdD, who has been studying heart health and sleep for six years in the Department of Medicine (in Cardiology) at Columbia University Vagelos College of Physicians and Surgeons. Her team’s research—including a study that found poor sleep among women correlates with worse cardiovascular health scores—was cited as evidence that led to the AHA checklist change.
According to research, more than 80% of cardiovascular events, including heart attack, abnormal heart rhythms, and coronary artery disease, are preventable with healthy lifestyles and management of known risks. The point of the checklist is to help everyone keep their hearts healthy.
Aggarwal spoke with us to explain why sleep joined nicotine exposure, physical activity, diet, weight, blood glucose, cholesterol, and blood pressure on the AHA Life's Essential 8 list.
How sleep impacts the heart
Sleep intertwines with other factors that impact cardiovascular health, so it’s always been an element.
Poor sleep can affect the heart indirectly by influencing our choices about food and exercise. “Our research shows not sleeping well may lead to increased food cravings and gravitation to less heart-healthy comfort foods high in saturated fat and sugar,” Aggarwal says. And when you don't eat well, you don't sleep well. The relationship works both ways, and the same is true for physical activity, she adds.
People who do not get enough sleep are also more likely to develop high blood pressure, which increases the risk of developing heart disease.
Lack of sleep also promotes inflammation. “You need inflammatory cells to protect you from illnesses, but too many that stay for too long even when there’s no danger can result in chronic inflammation and, eventually, heart disease,” Aggarwal says. Research from Columbia scientists shows that even relatively mild sleep problems can cause inflammation in the endothelial cells that line the veins, which could significantly contribute to the development of cardiovascular disease.
Short sleep duration (SSD)
Defined as sleeping less than 7 hours per night, SSD affects over 33% of U.S. adults and is associated with increased mortality.Too much sleep can cause problems, too, though the reasons are still undetermined. The current hypothesis is that excess sleep itself is not harmful, but people who sleep more than nine hours per night are likely to have depression or other illnesses that impact the heart.
“Sleep is easy to measure and easy to modify,” Aggarwal says. “And like the other things on the AHA list, it’s something you can change. Yet more than one third of American adults do not sleep enough to protect their health.”
Consistency of sleep is vital to heart health
The heart likes consistent sleep, according to some of the most recent research on sleep and heart health. In a study that followed older adults for five years, those with the most irregular sleep schedules were nearly twice as likely to develop heart disease as those with more regular sleep patterns.
It’s not known why going off a regular sleep schedule (with consistent bed and wake times) affects the heart, but sleep inconsistency may disturb the body’s circadian rhythms. Heart rate, blood pressure, and other cardiovascular functions vary with the time of day and may become disrupted by inconsistent sleep.
