Getting eight hours sleep may be critical for your blood pressure \u2014 and your heart.<\/p>\n\n\n\n
A bad night\u2019s sleep can result in a spike in blood pressure that night and the following day, according to the results of new research released Wednesday. The study, published in the latest edition of the peer-reviewed scientific journal Psychosomatic Medicine and led by scientists at the University of Arizona, offers one possible explanation for why sleep problems have been shown to increase the risk of heart attack, stroke and even death from cardiovascular disease.<\/p>\n\n\n\n
Some 300 men and women, ages 21 to 70, with no history of heart problems were given portable blood pressure cuffs for two consecutive days. The cuffs randomly took participants\u2019 blood pressure during 45-minute intervals throughout each day and also overnight. They also wore \u201cactigraphy monitors\u201d on their wrists that measured movement to help determine their \u201csleep efficiency.\u201d<\/p>\n\n\n\n

\nThose participants who had lower \u201csleep efficiency\u201d showed an increase in blood pressure during that restless night. They also had higher systolic blood pressure \u2014 the number in a person\u2019s blood pressure reading \u2014 the next day. The researchers said getting a good night\u2019s sleep is important for good long-term health, but so is getting quality sleep, and recommended keeping your smartphone in another room, and pulling down the shades if your bedroom faces east.<\/p>\n\n\n\n
\u201cBlood pressure is one of the best predictors of cardiovascular health,\u201d said lead study author Caroline Doyle, a graduate student at the University of Arizona\u2019s Department of Psychology. \u201cThere is a lot of literature out there that shows sleep has some kind of impact on mortality and on cardiovascular disease, which is the No. 1 killer of people in the country. We wanted to see if we could try to get a piece of that story – how sleep might be impacting disease through blood pressure.\u201d<\/p>\n\n\n\n

Short sleepers had a 48% increased risk of developing or dying from coronary heart disease and a 15% greater risk of developing or dying from stroke, according to a 2011 study published in the European Heart Journal analyzed the sleep patterns of almost 475,000 people over 25 years.<\/p>\n\n\n\n
Scientists have also said a lack of sleep over a prolonged period of time can lead to calcification of arteries, hypertension (higher blood pressure), the release \u201cC-reactive protein,\u201d which is connected with stress and inflammation, and reduce insulin, which regulates blood sugar levels.<\/p>\n\n\n\n
Scientists say a prolonged lack of sleep can lead to calcification of arteries.
\n\u201cPatients with sleep apnea often have compromised heart health,\u201d according to the National Sleep Foundation. \u201cThis is because without long, deep periods of rest, certain chemicals are activated that keep the body from achieving extended periods in which heart rate and blood pressure are lowered.\u201d This 2008 study in the Journal of Clinical Sleep Medicine concluded that individuals with severe sleep apnea are at increased risk for coronary artery disease, congestive heart failure, and stroke.<\/p>\n\n\n\n
There are other ways to reduce hypertension. A diet that helps people reduce high blood pressure or hypertension may also reduce the risk of heart failure in people under the age of 75, according to separate research recently published in the latest edition of the American Journal of Preventive Medicine, and led by doctors at Wake Forest School of Medicine, which is part of Wake Forest Baptist Health in Winston-Salem, N.C.<\/p>\n\n\n\n
An observational study of more than 4,500 people over 13 years showed that those individuals under 75 who most closely adhered to the Dash diet had a significantly lower risk of developing heart failure than those who were least likely to keep to the tenets of the diet. (Dash is an acronym for Dietary Approaches to Stop Hypertension.)<\/p>\n\n\n\n
The study recommends cutting five things out of your diet: This Dash diet recommends eating fruits, vegetables, nuts, whole grains, poultry, fish and low-fat dairy products, while reducing consumption of three main components: salt, red meat, sweets and sugar-sweetened beverages. It is very similar to the Mediterranean diet, but the Dash diet recommends cutting out two more things: full cream (in favor of low-fat dairy products) and alcoholic beverages.<\/p>\n","protected":false},"excerpt":{"rendered":"
