One of the interesting things that I’m running into as I research all of the factors involved in Alzheimer’s disease is the absolute richness of the research. Well, perhaps I should say it’s the staggering richness of the numbers of research and articles on sleep.
But having said that, as in all things research on the Internet, the challenge is to winnow out the wheat from the chaff.
Quality of Research
One of the studies I’m reading, the National sleep foundation’s sleep quality recommendations, illustrated quite nicely this particular problem. This particular report is a systematic review of peer reviewed literature on sleep between the years 2005 to 2015. They used six entire databases – pulling up the sleep-related articles – of medical research. Let me quote, “a total of 3928 unique articles were identified, 386 articles were selected for full text review, and 277 studies met the final inclusion criteria.”
In other words, less than 10% of all articles met the criteria for being evaluated.
It’s absolutely fascinating when you read this document, and it’s in very tiny print, how much evaluation has been done on sleep quality already. I’ll have much more for you on how to fix your sleep in the near future.
But in the meantime, here are two reasons you want to get a better night’s sleep.
How To Lose Weight By Sleeping Better
One of the other studies I read described how weight gain is correlated to the amount of sleep you get. It turns out there are two hormones that determine how much food we want to eat: ghrelin and leptin.
- Ghrelin stimulates how much you want to eat
- Leptin reduces the amount you want to eat.
What we know for sure is that when you don’t get a good nights sleep, the level of ghrelin goes up and leptin goes down. A poor night’s sleep leads to you getting the munchies.
Injuries Are Worse For Sleepless Seniors
And yet a third study pointed out how sleep deprivation with athletes lead directly to a higher risk of injury and a slower recovery time once injured. You can appreciate that this will be the same for seniors.
Reading through all of these research papers is both fascinating and time-consuming. But I do believe it’s important, particularly after having read a few of these reports indicating the very serious effects on our physical health, that we all understand the importance of sleep.
Stay tuned. I’m about to lose weight and get healthier by getting a better night’s sleep. I’ll pass along what I’m learning right here.
