Tips to Fall Asleep Naturally
Get the nightly rest you need with these smart strategies.
Sleep has many important health benefits: It cleanses the brain, allows memories to consolidate, helps the immune system to function optimally, and restores and rejuvenates tissues. Not enough sleep impairs judgment and physical function. And let's face it, when tired, most of us can be rather irritable and grouchy. Serious health problems can result from poor sleep, including feeling more depressed and increasing the risk of falls.
Common Heart Tests
What these tests reveal and when you might need one.
In broad terms, the heart mainly consists of a plumbing system and an electrical system. There are two pumps: one uses arteries to push oxygenated blood from the heart to the rest of the body; the other pump uses veins to usher blood back to the heart and into the lungs to get re-oxygenated. Your pulse, or heartbeat, is controlled by the heart's electrical system. These systems can be measured with various tests to check for abnormalities. Given that heart diseases claim more lives than all forms of cancer combined, it might seem logical to get all the common heart tests possible as a preventative measure. But that's not what experts recommend.
