- Aging and longevity: Some studies suggest that maintaining optimal levels of GH may have benefits for aging individuals, potentially improving vitality.
How is Growth Hormone Regulated?
The secretion of growth hormone is regulated by several factors including:
- Sleep: GH is primarily released during deep sleep stages.
- Exercise: Physical activity can significantly boost GH levels.
- Nutrition: Certain dietary choices can influence GH production, with protein-rich foods often having a positive effect.
- Age: GH levels typically decline with age, which can affect overall health and vitality.
