Has your circadian rhythm been disrupted?  If you are wondering what that really is, the circadian rhythm is the name given to the “internal body clock” that regulates our 24-hour cycle of biological processes. There are patterns of brain wave activity, hormone production, cell regeneration, and other biological activities linked to this 24-hour cycle.

The circadian rhythm is important in determining sleeping patterns such as when we sleep and when we wake every 24 hours. The normal circadian clock is set by the light-dark cycle over 24 hours.  This gives some insight into how our recent time change might affect our circadian rhythm.

We often associate the “falling back” from Daylight Saving Time as an opportunity for an extra hour of sleep.  However, many people don’t, or can’t take advantage of the extra hour of sleep when “falling back.”  The resulting shift in the body’s daily sleep-wake cycle can disrupt sleep for several days.
