Hormones cycle
Melatonin and cortisol are in an opposite relationship; when
melatonin is high, cortisol should be low and vice versa.
MELATONIN
It is the hormone that signals night rest to the human body
and makes us feel tired. The primary role of this hormone is to
maintain the biological clock and to adjust the body’s rhythm.
It’s produced from serotonin in the pineal gland and secreted
during the night. It can be inhibited by exposure to light
during the night.
CORTISOL
Cortisol wakes us and should be at its peak in the
morning when it increases human activity and alertness. It’s
often referred to as the stress hormone as it is released due to
stress. It has a stimulating effect on various bodily functions.
It’s produced by the adrenal glands, which are on the top of
each kidney.
