Tick Tock Your Internal Clock

Phones and computers are good about adjusting to turning back the clocks. People don’t adjust as easily. Our internal clocks have no settings that can be reprogrammed.

Hey, it’s only an hour difference. “But it turns out that the master clock in our brain is pretty hard-wired, ” says Fred Turek, director of the Center for Sleep & Circadian Biology at Northwestern University.

Our internal clock is synchronized to the 24 hour light/dark cycle and daylight is a primary cue to reset the body’s clock each day.

It should only take a few days for your body and brain to catch up, but that the shift to daylight saving time in the spring, when we lose an hour of sleep, is linked to an increased risk of heart attacks and traffic accidents according to a new study which found an increase in the number of patients admitted to the hospital for a atrial fibrillation (irregular heartbeat) in the days following the spring time change.

One of the newer findings has been that the internal clock in our brains that we often refer to is supplemented by a time-keeping mechanism in every cell. Our bodies seem to like routine and when we disrupt those with clock changes or changes to our sleep or eating routines, it can increase the risk of metabolic disease.

Add to this the decrease in daylight also throws off routines, socialization and our emotional rhythm.

Okay, enough bad news. What can we do to compensate?

  • Go to bed an hour or so earlier.
  • Maximize your exposure to daylight in the morning hours.
  • Use foods that nourish – add protein sources like fish, nuts and other plant-based proteins such as tofu are good if you’re trying to cut back on meat.
  • Salmon and tuna are good for getting omega-3 fatty acids which regulate mood by quieting down the body’s response to inflammation.
  • Eat dinner early and keep it light or even make midday your main meal.
