The Mid-Afternoon Dip
The book is called Power Sleep and it is by the sleep researcher who coined the term “power nap”:
The author includes the following two diagrams on pages 48 & 49 that have thus far been my favorite insight from the book:
The second figure illustrates that at all times during the day we have two forces working on us: a “wakefulness” force and a “desire to sleep” force. In other words, at any point during the daytime if you lay down on your couch you could probably fall asleep.
The reason I thought the graph was so interesting is the fact that it shows a significant mid-afternoon dip in wakefulness. I thought I uniquely suffered from this condition – and suffer I do. Turns out it is common in our species.
You could basically set a clock by my profound desire to take a nap at exactly 3:00 PM. I am more tired at 3:00 PM than at any other time of day. I wish I could relocate my mid-afternoon tiredness to 10:30 PM.
Nature wants us to take a siesta!
