Sleep is Good

Hey, we all love sleep. Its like money, you can never get enough. Hey, we all love sleep. Its like money, you can never get enough—wait, did I just repeat myself? I forgot I said that. Maybe I need more sleep. According to a new study, getting enough shut-eye sharpens your memory. Juhie Bhatia of HealthDay News reports:
In the study, the researchers focused on sleep's impact on "declarative" memories, which are related to specific facts, episodes and events.


"We sought to explore whether sleep has any impact on memory consolidation, specifically the type of memory for facts and events and time," Dr. Jeffrey Ellenbogen, an associate neurologist at Brigham and Women's Hospital, Boston said. "We know that sleep helps boost memory for procedural tests, such as learning a new piano sequence, but we're not sure, even though it's been debated for 100 years, whether sleep impacts declarative memory."

The study involved 48 people between the ages of 18 and 30. These participants had normal, healthy sleep routines and were not taking any medications. They were all taught 20 pairs of words and asked to recall them 12 hours later. However, the participants were divided evenly into four groups with different circumstances for testing: sleep before testing, wake before testing, sleep before testing with interference, or wake before testing with interference.
Dr. Fuhrman thinks getting your Z’s is a pretty good idea too. In fact, he believes that getting sufficient rest is an important part of achieving health and longevity. He talks about it here:
Adequate sleep is a necessary component of good health. Our modern society stays up late into the night and wakes in the morning to an alarm clock—long before sleep requirements have been fulfilled. To make matters worse, most Americans partake in stimulating substances—such as caffeine and sugar—to remain artificially alert during the day.


During sleep, your body removes the buildup of waste in the brain. Sufficient sleep is necessary for the normal function of your nervous and endocrine systems. Most civilizations in human history recognized the value of mid-afternoon naps. The desire for a rest, short sleep, or “siesta” after lunch should not be seen as an abnormal need, but rather a normal one. People who “cover up” their lack of sleep by using drugs (such as caffeine) as food and/or food (such as highly processed, sugary foods) as drugs sometimes claim (even boast) that they can get by with very little sleep. As you begin to live more healthfully, you may quickly recognize that you need more sleep than you previously thought.

Do folks eating a nutrient-dense diet need less sleep than folks eating a SAD diet? Our children, in particular, seem to need FAR less sleep than their peers and we have been wondering how much their diet is affecting this.

I have heard that you don't need as much sleep eating a nutrient dense diet. How much sleep do we need?

I think how much we need varies; but I do recall reading last year that the general amount needed for most of us has been increased: It went from the long-standing 8-hour requirement to 10!

I think we're just all different and it will vary.
It seems the elderly sleep a lot less...

I do well at between 6 and 7 hours, 6 being most frequent.

I need lots of sleep. I must be getting younger.
