Have you ever wondered why you wake up before your alarm clock?
This article explains how new studies show that humans do have a special biological clock that allows us to wake up in the morning. This “clock” gets our metabolism going early in the day, the signal to wake up our bodies. The important part of this biological clock is a protein called PERIOD (PER). This protein rises and falls in our bodies throughout a 24 hour cycle. When PER lowers at night, our heart rate slows, our blood pressure lowers, and our mental processes slow down. Now, through studies funded by Salk’s Innovation Fund, it is found an enzyme helps raise the PER protein once again in the morning. This enzyme, JARID1a, is required for normal cycling, including the circadian rhythm.
Have your grandparents ever wondered why they can not sleep at night as well anymore? Findings show that as you grow older, your biological clock declines, and with it, a difficulty in sleeping.
Even diabetes has been linked to this research. Diabetes goes in turn with the biological clock, which controls its metabolic cycles. The conversion of fats and sugars only take place at certain times of the day. With someone who has diabetes, this suggests that the biological clock has lost control.
Numerous times I have woken up before my alarm clock, frustrated about not getting those extra few minutes of sleep. Now, through this study, I understand that its my bodies’ protein levels telling my metabolism to start the day.
