20 Facts & Tips About Your Body Clock

I really enjoyed reading The Secrets Our Body Clocks Reveal (you can read my full book review by clicking here). From this book, I’ve begun implementing a few of the tips I discovered. Here are a few of the facts and tips that I found interesting. 

  1. “Most of us reach our peak of alertness around noon. … We are least alert during the early morning hours—specifically, between 3:00 a.m. and 6:00 a.m.” 
  2. “Your immediate, or short-term, memory is best during the morning hours. … Your long-term memory is a different matter, however. Afternoon is the best time for learning material that you want to recall days, weeks, or even months later. … How well you remember things depends on when you learn them, not when you recall them.” 
  3. “On average, we tend to do best on cognitive tests—things that require the greatest mental effort—during the morning hours, particularly the late morning hours.” 
  4. “All of your senses—taste, sight, hearing, touch, and smell—are their keenest during the twilight hours of late afternoon and early evening.” 
  5. Tips for keeping your daily rhythms on beat: (1) get out in the sun for at least fifteen minutes each day, and (2) try to follow a regular daily routine.
  6. “Fortunately, there is another way to avoid the Monday morning blahs. Stay up as late as you like, but make sure you get up at your regular wake up time. In other words, don’t sleep in. And don’t take naps during the day. Then, when night rolls around again, you’ll find yourself able to fall asleep at or before your regular bedtime, and you’ll avoid pushing your cycle ahead.” 
  7. “Scientists have also discovered that short naps (twenty minutes or less) are just as revitalizing as long ones—and less disruptive to regular sleep rhythms. In addition, regular nappers wake up more refreshed than those who take only an occasional nap. When naps are part of the regular daily rhythm, they are less disruptive.” 
  8. “Generally, our moods peek around four hours after we awaken.” 
  9. “A regular exercise program can go along way toward easing the physical effects of stress. … The exercise program must be regular, however; sporadic physical activity, such as an occasional game of tennis or softball, or an activity that is not appropriate to your physical condition, can be a harmful stressor.” 
  10. “Melatonin’s daily rhythm is similar to that of legendary vampires: it appears at the onset of darkness and begins to disappear at the break of dawn. In other words, darkness triggers the chemical’s release; sunlight suppresses it. It should come as no surprise, therefore, that melatonin reaches its seasonal peak in the body during the dark winter months.” 
  11. “Beards tend to grow the most on Sunday and the least on Wednesday.” 
  12. “If you wake up in the morning with a temperature of 99° F, you are very likely coming down with a cold, the flu, or some other kind of illness. But if you have that same reading around dinner time, you may be in perfect health. The reason, of course, is that your temperature rises during the day. A high reading early in the day is a greater indication of illness than the same reading late in the day.” 
  13. “Take a commonplace drug like aspirin, for example. When swallowed at 7:00 a.m., aspirin stays in the body for up to twenty-two hours. When the same dose is taken at 7:00 p.m., it is completely out of the body within seventeen hours.” 
  14. “When you know your rhythms are out of sync, be aware that you are particularly vulnerable to illness. It is the time to be extra careful about keeping your distance from people with the flu or other viruses.” 
  15. “The best thing you can do for a tension headache is to learn how to relax. As soon as the headache begins, lie down, if possible, so you can take the strain off your neck, since this is the location of most of the muscles that tense up and cause a tension headache. Close your eyes and breathe deeply to return oxygen to your strained muscles. Better yet, ask a sympathetic friend or loved one to gently massage your neck and shoulders.”
  16. “Eat your biggest meal at breakfast, your next biggest at lunch, and your smallest at dinner.” 
  17. “About every ninety minutes, most people experience an urge to put something into their mouths. … Generally, it will pass in about fifteen minutes.” 
  18. “According to recent studies conducted at Northwestern University, both morning and night people perform simple mental tasks better during the morning hours after consuming the caffeine equivalent of one to three cups of coffee. But when the tasks become more complex, only night people do better under the influence of caffeine. For morning people, the higher dose of caffeine, the more mistakes they make.” 
  19. “Carbohydrates help calm and focus your mind.” 
  20. “Protein foods increase your alertness and help you feel more energetic. … Protein can be eaten either alone or with a carbohydrate food to energize the mind. For carbohydrates to have their calming effect, they must be eaten alone.”

7 Tips For A Better Night’s Sleep

Psalm 4.8It’s no secret that being tired can lead to a lot of not-so-nice consequences. Everything from automobile crashes, to poor work performance, to foot-in-mouth statements, to giving in to temptations, to health issues are all traced back to not getting enough peaceful sleep.

But did you know that sweet sleep is something God wants to give you?

Psalm 127 says, “God grants sleep to those He loves.” Guess what? God loves you, and wants you to have a peaceful night’s sleep!

Here are some benefits to getting solid sack time:

  1. Muscles are repaired—the body “turns off” muscles during sleep so they can repair themselves.
  2. The hormone leptin, that regulates your appetite, is adjusted.
  3. Your blood pressure is lowered.
  4. Your heart rate is lowered.
  5. The energy-producing cells we all need are restocked.
  6. Your immune system is re-energized.
  7. Memories are consolidated from short-term memory banks to long-term memories.
  8. The hormones that allow you to concentrate are replenished.
  9. Your “database” of decision-making options is re-calibrated.
  10. Bottom line—you get healthier physically, mentally, emotionally, relationally, and spiritually.

All of this God wants to give to those He loves. “God loves me, so I’m going to sleep peacefully tonight!”

The problem is we often sabotage God’s blessing of sweet sleep by our own poor decisions during the day. So here are seven things you can do to cooperate with God’s blessing of sleep:

  1. Reduce stress. Stress causes your body to release cortisol, which prepares your body for fight-or-flight. This means when you’re trying to quiet down for the night, your body is still screaming, “Go, go go!” Stress is mainly triggered by worrying over things outside of our control, so check out what Jesus said to us about not worrying—Matthew 6:25-34.
  2. Reduce late-day caffeine. Caffeine has a half-life of six hours, so if you are pouring it into your body late in the date, you might fall into bed exhausted but the caffeine is keeping your brain buzzing. As a result, you don’t have the normal deep sleep patterns.
  3. Eliminate emotional caffeine. Arguments with other people release cortisol and adrenaline in your bloodstream. If these disagreements are happening later in the day, your body is fighting against God’s plan for your tranquil sleep. So take care of any disagreements quickly (Ephesians 4:26).
  4. Exercise. Getting some movement into your daily routine flushes cortisol and adrenaline from your bloodstream.
  5. Go to bed and get up at the same time. There’s a reason God made the sun to rise and set at predictable times. Your body also functions best on a predictable schedule.
  6. Reduce “blue lights” close to bed time. The blue light waves of dawn tell our bodies to stop releasing melatonin, the sleepy hormone. The red light waves of dusk tell our bodies to increase melatonin so we can go to sleep. But when we’re staring into the blue light of our phones and tablets, our body is being sent a conflicting signal.
  7. Pray. Two great passages you can pray before bedtime are Psalm 4:8 and Proverbs 3:24. Claim those promises of sweet sleep!

God loves you. He wants to give you the blessing of peaceful sleep. If you’re going to sleep peacefully tonight, make sure you are not sabotaging what God wants to give you.
