The Science of Sleep

• Sleep plays vital roles: psychological wellbeing, memory consolidation, emotional regulation, cognitive functions, and physical restoration.
• There are two primary types of sleep: REM (Rapid Eye Movement) – important for mood regulation and memory consolidation, and NREM (Non-Rapid Eye Movement) which has three deepening stages.
• Circadian Rhythm, our internal 24-hour clock, dictates our daily pattern of alertness and drowsiness, affected by environmental light and darkness.

Sleep and Wellbeing

• Sleep affects cognitive processes such as memory, decision-making, and creativity.
• Synaptic pruning during deep sleep trims and strengthens neuronal connections.
• Emotional regulation is influenced by sleep; poor sleep can exacerbate stress and emotional management.
• Sleep also strengthens our immune system by producing infection-fighting antibodies, making lack of it detrimental to physical health.
