Your body clock is a powerful time piece. The meridian clock combined with your circadian rhythm can tell a lot about your physical and emotional health. Throughout the day body systems are active or resting at different times. Knowing what systems are active when can give you insight into what problems you are facing or may face soon. The circadian rhythm is that inner clock that knows to get up when the sun rises and to get sleepy when it sets. Our modern culture with black out curtains and bright electronics late at night can confuse our circadian rhythms and leave our bodies a little confused about when we are supposed to do what.
