Something else I’ve been reading is how deep sleep boosts IGF-1 because of growth hormone release, and I understand that this ties into the circadian rhythm. But I’d like to get a clearer picture of how the body’s internal clock affects IGF-1 regulation. If your circadian rhythm is disrupted, like from irregular sleep or shift work, how much does that impact IGF-1 levels over time?
