How do I know coffee makes me smarter? Is there science behind this statement, or is this just a perception I have? Scientists giving people 200 mg of caffeine—the equivalent of a couple of cups of coffee—found they help the brain identify words more quickly and precisely. I call that “smarter.” Our IQs aren’t higher, but we can use what we have better.
Does it take two cups, or two sips? Perhaps this depends upon a person’s sleep debt. According to the PLOS Journal, “Sixty-six healthy participants age 24.3 years (19–32 years) were randomly assigned to either a caffeine group (n = 33, 9 males) or a placebo control group (n = 33, 12 males).” Do I know these young men were sleep deprived, or is it my best guess? Men average 5 hours, 45 minutes, while women average 6 hours, 9 minute, according to a 2017 study on American sleep habits.
Excessive fatigue during the day and taking too long to fall asleep were the most common reported issues. The recommended amount of sleep is 7 hours. An interesting side note, every 30 minutes of daily exercise adds about 14 minutes of sleep time. I have the blessing of inheriting my daddy’s ability to fall asleep as soon as my head hits the pillow. “Go all day, sleep all night.”
As I was saying, I worked all evening long to fix printer at home. Reason(s)?
1. Power surge last week might have knocked out delicate “air connections” of the software.
2. My iPad crashed and I had to restore it. No telling what happened there! I was fortunate to have backed up just a few days prior.
3. Printer would print from computer & phone, but the iPad would not recognize the printer. I went to bed. Arkansas had lost their baseball game anyway.
4. When all else fails, a good night’s sleep might solve any problem. It will be there anyway and I can try again.
5. Morning and coffee bring new insights. If I was stuck trying to print from email, why not print from another program on the iPad?
6. Print from Word. Spits out a page!
7. Print from Notes. Spits out another page!
8. Now go to email and try again. BINGO! We have a winner! Chicken Dinner!
“Tomorrow is another day,” my mother always told me. “Things will look different when you wake up.” When I was young, I didn’t have her accumulated experiences to understand this wisdom, but the dawn always comes after the dark of night. We can either stay up worrying and exhaust ourselves, or get a good night’s sleep and wake up refreshed and ready to tackle life again in the morning.
I tend to let God handle the world and its troubles while I sleep. In the morning, I thank God for another day to love and serve, and take care of the troubles that come my way. I don’t go looking for trouble, since like most of us, we have enough trouble in our own lives to begin with! And trouble will find us along the way also.
If I could give you one word of suggestion, most problems in our lives would go away if we all slowed down. We attempt to pack 30 hours of activity into a 24 hour day, and then wonder why we’re so tired. Sleep deprivation is the answer, with stress as a corollary result.
The University of Washington Health Sciences concluded chronic sleep deprivation suppresses the immune system, which means people get sick more often when they don’t get enough sleep.
Dr. Nathaniel Watson, co-director of the UW Medicine Sleep Center at Harborview Medical Center says, “What we show is that the immune system functions best when it gets enough sleep. Seven or more hours of sleep is recommended for optimal health.”
Get 7 or more hours of sleep per night, and simplify your life.
Live long and Prosper.
