1. Deep Sleep and Growth Hormone:
Deep Sleep Defined: Deep sleep, or stage three sleep, is vital for physical repair and recovery. It’s during this stage that our bodies secrete the majority of growth hormone (75-85% of total growth hormone), which is essential for maintaining muscle mass, skin health, and metabolism.
Growth Hormone Benefits: This hormone plays a critical role in physical repair and metabolism regulation, helping seniors combat health problems such as muscle loss and poor skin elasticity.
2. The Glymphatic System:
Function: The glymphatic system clears waste products from the brain, including the beta-amyloid proteins linked to Alzheimer’s disease.
Connection to Cognitive Health: Proper function of this system during deep sleep helps reduce the risk of cognitive decline, a common concern for seniors.
3. Melatonin’s Multi-Faceted Role:
Melatonin Basics: Melatonin, known as the "hormone of darkness," is crucial for regulating sleep-wake cycles. It also acts as a powerful antioxidant, providing anti-inflammatory and neuroprotective benefits.
Melatonin and Aging: As we age, melatonin production decreases. Maintaining adequate melatonin levels through proper sleep hygiene and possibly supplementation can help seniors maintain their health.
4. Telomere Preservation:
Telomere Function: Telomeres protect our DNA during cell replication. Shortened telomeres are a marker of aging and are influenced by poor sleep.
Sleep and Telomeres: Good sleep hygiene can help preserve telomere length, promoting cellular health and longevity.
