Purpose of Sleep:

  • Restoration
  • Memory Consolidation
  • Metabolic Health
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.

Memory Consolidation

The second purpose of sleep is 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.
