@instituteofhumananatomy: 🧠 This tiny gland at the base of your brain controls how you grow, recover, and even how you sleep. The pituitary gland releases growth hormone — critical for development during childhood and adolescence, but also essential for adults for tissue repair, recovery from exercise, and lean body mass. But the pituitary isn't the one calling the shots. That's the hypothalamus — sitting just above it, constantly monitoring the body. Sense a stressor like exercise? It tells the pituitary to release more growth hormone. Detect that you've hit deep sleep? Same thing — there's a major spike of growth hormone in the first two hours of deep sleep. 😴 That's why quality sleep isn't just rest — it's recovery at a hormonal level.
