Growth hormone secretion diminishes starting in the early 30s and is normally released during slow-wave sleep, particularly in the early part of the night.

“early 30s or so, the amount of growth hormone that we secrete is greatly diminished. Normally we would release growth hormone every night, after we go to sleep, in particular in the early part of the night when our sleep is comprised mostly of slow-wave sleep. As we age, less growth hormone is released during that slow wave sleep.”

“as all of us age, when we go from adolescence to our teenage years and then into a young adulthood, but then starting in our early 30s or so, the amount of growth hormone that we secrete is greatly diminished. Normally we would release growth hormone every night, after we go to sleep, in particular in the early part of the night when our sleep is comprised mostly of slow-wave sleep.”

“I'd like to talk about growth hormone first because it's actually a pretty short discussion first of all the best way to augment growth hormone is to get quality deep sleep especially the sleep that occurs in the first three or”

“first of all the best way to augment growth hormone is to get quality deep sleep especially the sleep that occurs in the first three or four hours of the night is when growth hormone is released”

“So growth hormone release happens all day long and all night long, but the deep, slow wave sleep that you get the very first sleep cycle is when you get a big bolus of growth hormone release, in men and women equally. And if you miss that first deep, slow wave sleep period, you also miss that big bolus of growth hormone release. And you might get, ultimately across the day, just as much overall growth hormone release, but endocrinologists will tell you that big boluses do different things than a little bit eked out over time.”

“I can block or not block I can reduce significantly reduce your growth hormone because I selectively deprived you of sleep”

“the growth hormone surge is greatest at the beginning of the night of sleep and that if we go to sleep a few hours later than usual we miss the opportunity to experience the same level of growth hormone release”

“why it's important for people to be asleep by 10 p.m. between 10: p.m. and 2: a.m. because you think that's the B largest pulse of growth hormone during the 24-hour period is that right”

“On the one hand, the majority of daily growth hormone secretion occurs in the initial phase of slowwave sleep. On the other hand, growth hormone and its releasing hormone, growth hormone releasing hormone have also been shown to promote sleep, particularly slowwave sleep.”
