Healthline: Sleep impacts your hormones and hormone levels impact your sleep.
Various hormone functions and their release are impacted by sleep or circadian rhythm and vice versa.
For example, melatonin controls sleep patterns and tells your body when to get to sleep. Human growth hormone is released during deep sleep hours, which is vital to cell growth and repair.
Other hormones, like cortisol, depend on sleep timing, duration, and quality for their release.
Good sleep is crucial to health, according to Sara Gottfried, MD, a clinical assistant professor in the department of integrative medicine and nutritional sciences at Thomas Jefferson University.
Nearly every hormone in the body is released in response to your circadian rhythm, also known as the sleep-wake cycle.
“When ignored, poor sleep will make you fall down a hormonal flight of stairs,” Gottfried says. “That’s true, whether you’re 30, 50, or 70.”
