Sleep is a highly active time for brain development and brain function. There are four primary stages of sleep including Rapid Eye Movement (REM) when we dream and deep sleep or stage four sleep. It is thought that deep sleep and REM tend to decline with advanced age and these are perhaps the parts of sleep when consolidation of information takes place. As such sleep quantity and quality have a major role in what and how well we process and remember information.

REM sleep occupies about 25% of our total sleep and it is during REM that we dream. We tend to be paralyzed during this part of our sleep so we cannot act out our dreams. Without REM and deep sleep we can become lethargic, depressed, and make mistakes. Significant sleep disorders affect more than 35 million Americans and many more around the world. Sudden sleep is known as narcolepsy and can occur while driving which leads to a high number of fatal car accidents. Sleep Apnea, the first phase of narcolepsy, occurs because of a blockage of the airway and results in sudden gasps for air while sleeping. Apnea is most common in middle age, obese and hypertense males.

When considering lifestyle changes for brain health (e.g. brain fitness, brain games), one of the most important aspects of life is sleep. We tend to not get enough sleep and our brains run on fatigue much of the time. Napping is a lost art and we do not rest enough. As a result, our brains are over-stimulated, stressed, and tired. Consider this blog a permission slip to get a good night sleep and to take a nap sometime this week.
