THE CORTISOL & MELATONIN DANCE

CAN'T GET TO SLEEP?


CAN'T STAY ASLEEP?


WAKING TIRED & UNREFRESHED?


Your CIRCADIAN RHYTHM could be out of balance.


WHAT IS THE CIRCADIAN RHYTHM?


In humans, sleep/wake cycles follow a 24-hour pattern linked to Earth’s light/dark cycle.

The primary circadian clock in humans is located within the hypothalamus in the brain , and is regulated by key hormones and neurotransmitters such as MELATONIN, CORTISOL, gamma aminobutyric acid (GABA) and glutamate.


THE CORTISOL-MELATONIN DAILY DANCE


Cortisol responds to light , wakes us up and keeps us alert during the day. It should be at its peak in the morning. Melatonin is a hormone that your brain produces in response to darkness and is important for initiating and maintaining sleep.


Melatonin and cortisol are in an opposite relationship; when melatonin is high, cortisol should be low and vice versa.


These two hormones together play a vital role in co-ordinating the circadian rhythm and regulating sleep/wake cycle. When either of these gets out of balance, our ability to sleep is affected.
