Endocrine System and Sleep

Meaning

The Endocrine System and Sleep describes the bidirectional, highly integrated relationship between the body’s hormone-secreting glands and the regulation of the sleep-wake cycle. Optimal sleep duration and quality are essential for the proper pulsatile release and rhythmic secretion of numerous hormones, including cortisol, melatonin, growth hormone, and leptin/ghrelin. Conversely, disruptions in endocrine function, such as thyroid dysfunction or adrenal fatigue, significantly impair sleep architecture and quality, highlighting a core regulatory loop for systemic health. Maintaining this synchronized hormonal and sleep rhythm is a cornerstone of longevity and metabolic wellness.
