Just as the the whole of nature is governed by order, and life unfolds at its annual, monthly, weekly, or daily, rhythms, your body, through its functions, is perfectly correlated with the daily rotation of the earth around the sun. Inside you there is a “biological clock” that helps you anticipate changes and adapt to the regular day-night rhythm, creating the premises for your optimal functioning.
What exactly determines this daily rhythm? Firstly, the pineal gland, located in the center of the brain, produces a hormone called melatonin. Stimulated by darkness and inhibited by light, almost absent the entire day, melatonin is produced starting with 9PM, “preparing” you for the night sleep.
In the opposite direction, cortisol – the “stress”hormone is produced by the adrenal glands under the control of another unit in your brain responsible for the biological clock – the hypothalamus.
The synthesis of cortisol follows the same dayly rhythm, having its peak around 6to8 AM, before you wake up, just when you need energy to start your activities. It sustains the tension in your blood vessels and increases the level of glucose that will be your every day ”starting fuel”. Then, the cortisol undergoes a decline throughout the day, becoming undetectable at night during your first hours of sleep, resuming its cycle to reach its peak again during the next morning. Other episodes of cortisol addition, of small amplitude, occur during the day, when you eat or when you make psychical effort.
Thus, your inner clock adapts, with perfect precision, your physiology during the different phases of the day, adjusting essential functions – your body’s metabolism and temperature, hormone levels, your sleep, and even your behavior.
