As a lead in to some of the studies I have planned on the brain and how to help us protect it and keep it healthy, I’m sending this one that has to do with the proper amount of sleep. After studying how much sleep we need and how important napping is, I wrote over 15-years ago that humans need at least 7-hours and no more than 8-hours.
While I am interested in the brain and mood and how we can keep those two healthy (the mood strongly affects the health of the brain) and properly regulated (positive brain chemicals flowing when they should), the little report following my comments will mention other negatives of over-sleeping.
At this point, after studies ranging over the last 20-years, “sleeping too much seems to be worse than sleeping too little, the statistics show. Long sleepers have about a 20 to 30 percent increased risk for mortality; according to recent meta-analyses short sleepers, that number is about 10 percent.” (The Annals of Epidemiology)
Each end of the spectrum can cause brain damage and other health conditions. At this point I can say that everyone I know who has been chronically sleeping less than 7-hours per night has both long-term and short-term memory problems. They are irritable, negative, and have a serious problem focusing. They are slow to rise (healthy brains get out of the bed quickly without grogginess and mental lethargy), groggy, and often disoriented when they awake. They do, however, have a couple of degrees the best of the problem over long-sleepers. If they will take naps, they can equalize the problem.
On the other end of the spectrum, those who have been sleeping more than 8-hours, they are either consistently depressed and negative thinkers or they are manic (bi-polar) and lean toward the depressive side. They are slow to rise (healthy brains get out of the bed quickly without grogginess, disorientation, and mental lethargy) and irritable when they don’t sleep for long hours. They get words and phrases mixed up, have memory problems, and other health problems. They are chronic procrastinators. The problem on this end is that they simply cannot believe that you can sleep too much and that doing so is hazardous to their health. Denial is a serious problem on this end. On top of that, they are addicted to sleeping long hours. Chronic over-sleeping is at least a few degrees worse than sleeping too little, but it’s bigger problem because it is difficult to equalize the problem.
This little piece exactly mirrors the piece I put out 15-years ago. There are, however, even more studies out there today that show how dangerous to our health over-sleeping is.

Regularly Sleeping Over 8 Hours Increases Stroke Risk
In the study, researchers followed approximately 9,600 older adults (average age: 62) for about 10 years. During that period, subjects who reported clocking more than eight hours of shuteye nightly were 46 percent more likely to have a stroke, compared with individuals with more moderate sleep durations. Previous large research studies in the U.S. and China have found similar associations between sleep duration and stroke.
“Long sleep was significantly associated with an increased risk of stroke (hazard ratio [HR] = 1.46 [95% confidence interval (CI) 1.08, 1.98]) after adjustment for all covariates.”
