A new international study, executed by the Centro Nacional de Investigaciones Cardiovasculares Carlos III in Madrid, Spain, and Tufts University, USA, finds a link between healthy sleep during night time and the risk of cardiovascular issues.
For the study, the scientists analyzed the medical data received from 3,974 people with average age 46 years from Spain. They participated in the Progression of Early Subclinical Atherosclerosis study.
Having analyzed the data, the scientists concluded that participants who slept under 6 hours every night had the 27% increased the risk for atherosclerosis when the researchers compared them with people who slept between 7 and 8 hours every night.
A study, recently published in the European Heart Journal, suggests that excessive sleep, as well as insufficient sleep, may cause the risk of cardiovascular issues and premature death.
For the study, the researchers examined the sleeping habits of more than 116,000 aged between 35 and 70 years enrolled in the Prospective Urban Rural Epidemiology (PURE) study.
Having analyzed the received data, the researchers concluded that people who slept 9–10 hours were 17% more likely to die or develop cardiovascular conditions. People who regularly slept for more than 10 hours had a 41% risk to die prematurely or develop cardiovascular conditions.
Corresponding author Dr. Salim Yusuf, the principal investigator of the PURE study and a professor of medicine at McMaster, comments the results of the study: “The general public should ensure that they get about six to eight hours of sleep a day. On the other hand, if you sleep too much regularly, say more than nine hours a day, then you may want to visit a doctor to check your overall health.”
New research, executed by scientists from Iowa State University, finds that lifting weights for less than an hour once a week may lower the risk of heart attack or stroke by 40–70%. The researchers also add that performing weight exercises for more than an hour doesn’t provide any additional effect.
To make this conclusion, the researchers analyzed data from about 13,000 adults in the Aerobics Center Longitudinal Study measuring three health outcomes: cardiovascular events, heart attack and stroke in particular, that didn’t result in death, all cardiovascular events that resulted in death.
DC (Duck-chul) Lee, an associate professor of kinesiology explains: “Lifting any weight that increases resistance on your muscles is the key. My muscle doesn’t know the difference if I’m digging in the yard, carrying heavy shopping bags or lifting a dumbbell.”
New research, conducted by a team of scientists from McMaster University in Ontario, Canada, finds that people who consume three servings of dairy, including milk, cheese, butter, or cream, a day are almost two times less likely to suffer from heart disease and strokes than people who consume less dairy.
For their study, the researchers analyzed the data from more than 136,000 people from 21 countries aged between 35 and 70 who had taken part in the Prospective Urban Rural Epidemiological (PURE) study. The study focused on environmental, societal, and biological effects on obesity and chronic health issues.
Dr. Mahshid Meghan, a senior research associate at McMaster University, explains: “What I really want to emphasize is that consumption shouldn’t be discouraged but encouraged especially in low-income countries and even in high-income countries where consumption is low. We are not saying people eating seven servings of dairy a day should increase their intake, but that three servings – moderation – is good for you.’
According to a French study, recently published in JAMA, senior people with better heart health have the lower risk of developing dementia and cognitive decline.
For the study, the researchers followed 6,626 people aged 65 years and over for 8.5 years on average. The followed people lived in Bordeaux, Dijon, and Montpellier (France). The average age was 73.7 years. None of the followed had dementia or cardiovascular disease.
The researchers conclude in their study: “These findings may support the promotion of cardiovascular health to prevent risk factors associated with cognitive decline and dementia.”
To maintain good cardiovascular health, you should comply with the following recommendations: give up smoking; be physically active; include vegetables, fruit, and fish into your diet; keep your weight healthy; keep an eye on your blood pressure, cholesterol, and blood sugar.
