Cortisol Rhythm

Circadian alignment is presented as a foundational strategy for cortisol rhythm and sleep. A morning cortisol spike helps the body wake up, generate energy, and function through the day. Morning caffeine may help some people with low morning cortisol function because it can raise cortisol. Low-dose hydrocortisone is discussed only as a clinician-supervised option for selected low-cortisol contexts. The subject's cortisol rhythm shows low-end waking cortisol and abnormally low afternoon cortisol. Cortisol is described as an essential energizing hormone with circadian timing rather than only a harmful stress hormone. A flipped cortisol curve is described as low morning cortisol and high evening cortisol. Cortisol normally spikes early in the morning. Healthy cortisol is described as higher in the morning and lower in the evening. The cortisol pattern corresponded with flu-like morning fatigue and severe afternoon sleepiness. Missing bright morning light can make cortisol activity more spread out across the day. Abnormal cortisol timing is interpreted as a possible sleep or light-exposure issue in this case. Morning light and daytime activity signal wakefulness, while evening darknes…
