What is Insomnia?
Insomnia is defined as having difficulty falling asleep and/or staying asleep, which leads to a negative impact on the next day. It is a medical condition that touches the lives of approximately 60 million adults in the U.S. – making insomnia the most common sleep disorder. So if you're having trouble sleeping, it may be comforting to know that you’re far from alone.
According to the National Institutes of Health, the best amount of sleep for most adults appears to be 7-8 hours per night.
Missing as many as 2 to 3 hours can significantly impair work performance.
Prolonged insomnia can cause depression and emotional problems. In some cases, even psychiatric disorders.
Learn deep relaxationship techniques that will help you to achieve the sleep that you need to to keep your body in tip top shape.
We remember things by association. Every piece of information in our memory is connected to other pieces in some way or another. For example, if you are given the word "apple", what do you think of? But it's unlikely that we might see "apple" and think of "dog" (unless you remember some funny incident in which your dog investigated an apple). And what if you were asked what the 7th letter of the alphabet was? Chances are, you wouldn't know that "G = 7," but you could easily think to yourself, "A B C D E F G," and then say "G". You used association to get to the letter G, because you knew A was the first letter, then you kept choosing the next letter in the sequence until you got to the right one. Most of us don't. Most of us have a really good memory, but we just don't have practice in using it efficiently. Learn concentration techniques that will help you sharpen your memory and retention to have the recall you have always wanted.
