Did you know that “as you sleep, slow waves of electrical activity in your brain seem to help rinse away harmful waste products that could otherwise damage your brain cells“?
So says this New Scientist article.
In fact, the article suggests there could be a connection between sleep deprivation and Alzheimer’s disease. Wow! That’s a bit scary to think about.
What about you? Do you have problems sleeping? Do you toss and turn all night? Or maybe (like me) you sleep in spurts? Or are you one of the lucky ones that snoozes the whole night through?
While most of us simply FEEL better with a good night’s sleep, it’s also better for us overall. Healthline says this about sleep …
- Poor sleep can make you fat
- Good sleep can improve concentration and productivity
- Good sleep can maximize athletic achievement
- Poor sleep increases the risk of heart disease and stroke
- Sleeping affects your glucose metabolism (e.g., Type 2 diabetes)
- Poor sleep is linked to depression
- Sleep improves your overall immunity
- Sleep affects your emotions and social interactions
But wait! There can also be too much of a good thing! More than 9 hours of sleep a night may actually do more harm than good resulting in potential calcium buildup in your heart arteries.
It seems if a person gets 7-8 hours of sleep at night, it puts them in the “ideal” range.
So tell us. How did you sleep last night?
