Melatonin levels remain elevated throughout the night until daytime, when they fall to low levels once more. Morning light tells the SCN to begin performing processes such as raising our body temperature, releasing stimulating hormones (including cortisol), and delaying the release of hormones that promote sleep (such as melatonin) until it gets dark.Īs the sun sets, melatonin levels in the blood increase rapidly, which results in you feeling sleepy. The suprachiasmatic nucleus (SCN), a minuscule region of the hypothalamus, signals to other parts of the brain that control body temperature, hormones, and other functions that determine whether we feel drowsy or alert.
