Understanding Sleep Patterns. A great deal of the worry associated with insomnia may be related to our misconceptions about
sleep timing. Many of us adhere to the 8-hours-of-uninterrupted-sleep notion. This is the belief
that sleeping straight through for 8 hours is "normal." However, sleep research suggests that the
normal pattern may be what is called "segmented sleep." This is the idea that our natural rhythm
is to sleep for 3-4 hours, followed by a 1-2 hour awake period, and a second 2-4 hour sleep.
Historical evidence suggests that segmented sleep was once common, and our ancestors used
the mid-night waking period to visit with neighbors, have a snack, or have sex. (Psychology Today,
2019)
