1. The Science of Sleep
The average adult spends 36 % (or about one-third) of his or her life asleep.
Purpose of sleep:
- Restoration
- Memory consolidation
- Metabolic health.
2. Restoration
The first purpose of sleep is restoration.
Every day, your brain accumulates metabolic waste as it goes about its normal neural activities. Sleeping restores the brains healthy condition by removing these waste products. Accumulation of these waste products has been linked to many brain-related disorders.
3. Metabolical Health
When we sleep 5.5 hours per night instead of 8.5 hours per night (recommended is 8 hours), we tend to burn more energy using carbs and protein, instead of fat.
This can result in fat gain and muscle loss. Also, insufficient sleep or abnormal sleep cycles can increase the risk of diabetes and heart disease.
4. Memory Consolidation
Sleep is crucial for memory consolidation, which is responsible for your long-term memories.
Insufficient or fragmented sleep can hamper your ability to remember facts and feelings/emotions.
5. Cumulative Stress
6. How to Sleep Better
