Circadian Rhythms Promote Wakefulness

Circadian Rhythms Promote Wakefulness

Figure 3 shows the rise and fall of circadian rhythms for wakefulness.

The circadian rhythms

  • Create a peak in wakefulness in the evening, a few hours before bedtime
  • This may increase alertness in early evening, even after being awake for long periods of time, and may make it difficult to go to bed earlier.
