How in Tune is Your Body with Natural Circadian Rhythms? 1

Circadian rhythms are 24-hour cycles that are part of the body’s internal clock, running in the background to carry out essential functions and processes.  Circadian rhythms also play an integral role in diverse aspects of physical and mental health.  The image above shows some of the body’s natural rhythms  – it’s helpful to see how aligned your body is with the image above.

When your body’s circadian rhythms are off, the whole body is affected.  The digestive and endocrine systems especially can be affected negatively by eating too close to bedtime, waking up too early to exercise or exposing yourself to artificial light when your body should be in the dark. So what steps can you take to ensure a healthy circadian rhythm to ultimately lead to optimal wellness? 

  • Stop eating three hours or more before bedtime – studies show that people who eat more calories late at night tend to have more body fat and more insulin resistance.
  • Invest in blue light blocking glasses if you need to be exposed to artificial light and technology at night.  Best practice is to stay away from electronics one hour or more before bed.
  • Daily exercise has been shown to improve circadian rhythm across the board.  However, exercising too close to bedtime (90 minutes or less before bed) or losing sleep to exercise may be counterproductive.
