Morning Sun (more)
“Morning exposure to sunlight increases core body temperature, alerting, cognition and brain serotonin levels which enhance mood and vitality. As the day progresses, peak cognition occurs commensurate with maximal core body temperature. By evening, SCN actively inhibit cortisol secretion for recovery from the morning surge and initiate pineal secretion of the hormone melatonin which reduces alertness and decreases core body temperature. As sleep ensues, its slow wave stages and SCN suppression reduce cortisol to a healthy daily nadir as SCN orchestrate a nightly surge of melatonin and other sleep-related hormones.”
