Shakespeare referred to it as, “A small slice of death.” However, not getting enough sleep can turn that small slice into a thick slab. Getting enough rest has been found to be as important as getting enough nutrition. The link between sound sleep and health is well established. Contrarily, poor sleep has been connected to many ills that can, ultimately, cost you your life. According to the Harvard Medical School Guide to a Good Night’s Sleep, blood pressure and heart rate are typically at their lowest levels during sleep. People who sleep less than 8 hours nightly tend to have higher blood pressure. The link between hypertension and sleep duration could explain other research findings linking lack of sleep to increased risk of heart attack, diabetes, weight gain and other problems.

It’s estimated that 40% of Americans get less than 7 hours shut-eye every day and the accumulation of weariness is taking a toll on health. Some analysts believe it can be attributed to the growing seduction of the Internet, video games and endless television channels. People seem to have more reason to stay awake longer than did their ancestors. Yet, every scientific survey seems to indicate that sleeping well can help you fight off disease because your immune system will be stronger. A thoroughly rested body has lower levels of stress hormones which can augment immune function. That flu shot that you took may work better if you’re getting sufficient slumber. Then there’s the aging factor. We’ve all heard about getting our beauty sleep. That’s a function of growth hormones, which drop dramatically between the ages of 20 and 60. A notable heart surgeon says a high level of growth hormone produces more muscle mass, better skin and a more youthful look. He adds that the number one best way to achieve that is through proper sleep.
