A Calm Brain = Better Memory
Brains in a state of relaxation are better able to remember new information, according to a study conducted by researchers from the California Institute of Technology and Cedars-Sinai Medical Center in Los Angeles, and published in the August, 2010 issue of the journal Nature.
Experts Claim 7 hours of sleep is Optimal
According to a study published in the August 1, 2010 edition of the scientific journal , SLEEP, getting seven hours of sleep is optimal for maintaining heart health.
Getting too much, or too little, sleep can increase a person's chances of developing cardiovascular disease, according to the research.
What the researchers discovered was that people who sleep only five hours a day, with naps included, have TWICE the risk of suffering from angina, coronary heart disease, heart attack or stroke, compared to people who sleep seven hours a day.
In addition, it was reported, that people who sleep nine or more hours a day have a ONE AND A HALF times the risk of developing cardiovascular disease.
Those that slept either six or eight hours had only an "elevated but less dramatic risk" according to the report.
More findings included a sub-group of people over the age of 60. Researchers found that people over the age of 60 who sleep five hours or less a night are at the highest risk of developing cardiovascular disease. People in this category are at THREE TIMES higher risk than those who sleep seven hours a night.
And, women who get only five hours of sleep a night are at TWO AND ONE HALF TIMES the risk compared to those who get seven hours a night.
Why 7 hours seems to be the magic number is anyone's guess so "get a good night's sleep."
The Bottom Line…The Bottom Line…The Bottom Line…
We have always maintained that many factors can contribute to or detract from one's health and quality of life including rest, exercise, diet, clean air and water, a healthy nervous system and positive mental attitude. In this sleep study, an explanation was provided about how sleep duration affects metabolism and how too little sleep can impair glucose tolerance, reduce insulin sensitivity and increase blood pressure, increasing the risk of heart disease. Get your 7 hours!
