Getting eight hours of sleep can be essential for your blood pressure and your heart.
A bad night's sleep can cause a rise in blood pressure that night and the next, according to the results of a new study released Wednesday. The study, to be published in the latest edition of the peer-reviewed scientific journal Psychosomatic Medicine and led by scientists at the University of Arizona, offers a possible explanation for the fact that sleep problems increase the risk of heart attack, stroke and even the death of a cardiovascular disease.
Some 300 men and women between the ages of 21 and 70 with no history of heart disease received portable blood pressure cuffs for two consecutive days. Wrists randomly took participants' blood pressure at 45-minute intervals throughout the day and during the night. They also wore "actigraphic monitors" on their wrists, which measure movements to determine their "sleep efficiency".
"Blood pressure is one of the best predictors of cardiovascular health."
Participants whose sleep efficiency was lower had an increase in blood pressure during that restless night. They also had higher systolic blood pressure – the number of a person's blood pressure readings – the next day. The researchers said having a good night's sleep was important for good long-term health, but the same is true for quality sleep. It is recommended to keep your smartphone in another room and to lower the blinds if your room is oriented to the east.
"Blood pressure is one of the best predictors of cardiovascular health," said Caroline Doyle, lead author of the study, a graduate student in the Department of Psychology at the University of Arizona. "There are many books that show that sleep has an impact on mortality and cardiovascular disease, the leading cause of death among people in the country. We wanted to see if we could try to get an excerpt from this story – how could sleep affect diseases caused by high blood pressure.

According to a 2011 study published in the European Heart Journal, short-term sleepers were 48% more likely to develop coronary artery disease or die from coronary heart disease and 15% more likely to develop or die from heart disease. 39, a stroke years.
Scientists also claimed that a lack of prolonged sleep could lead to calcification of the arteries, hypertension (high blood pressure), release of "C-reactive protein", stress-related and inflammation, and a reduction in insulin, which regulates blood sugar.
Scientists say that a lack of prolonged sleep can lead to calcification of the arteries.
"Patients with sleep apnea often have compromised heart health," according to the National Sleep Foundation. "This is due to the fact that in the absence of long and deep periods of rest, some chemicals are activated, which prevents the body from reaching prolonged periods of lowering of the rhythm heart rate and blood pressure. " This 2008 Journal of Clinical Sleep Medicine study concluded that sleep apnea presents an increased risk of coronary heart disease, congestive heart failure and stroke.
There are other ways to reduce hypertension. A diet that helps people reduce high blood pressure or high blood pressure can also reduce the risk of heart failure in people under the age of 75, according to a separate study recently published in the latest number of the American Journal of Preventive Medicine and led by physicians from Wake Forest School of Medicine, which is part of Wake Forest Baptist Health in Winston-Salem, NC
An observational study of more than 4,500 people over the age of 13 showed that people younger than 75 who adhered most closely to the Dash diet had a much lower risk of developing heart failure than those who were less likely to stick to the principles of the scheme. (Dash is an acronym for Dietary Approaches to Stop High Blood Pressure.)
The study recommends removing five elements from your diet: this Dash diet recommends fruits, vegetables, nuts, whole grains, poultry, fish and lean dairy products, while reducing the intake of three main components: salt, red meat, sweets and sugar sweetened beverages. It looks a lot like the Mediterranean diet, but the Dash diet recommends removing two other things: the full cream (in favor of low-fat dairy products) and alcoholic beverages.
