“One-third of our lives is spent sleeping. Sleep quality directly affects daytime energy, emotional stability, cognitive ability, and physical health.”
However, according to statistics from the Chinese Sleep Research Society, over 300 million Chinese have sleep problems. Insomnia, vivid dreams, easy waking, light sleep… these problems are eroding modern people’s health and quality of life. This article provides a comprehensive sleep improvement guide to help you rediscover quality sleep.
Understanding Sleep: Why Sleep Is So Important
Functions of Sleep
- Physical repair: During sleep, the body performs tissue repair, muscle growth, and immune function enhancement
- Memory consolidation: Sleep helps the brain organize and consolidate information learned during the day
- Emotional regulation: Sleep deprivation leads to mood swings, increased anxiety, and higher depression risk
- Metabolic regulation: Sleep affects hormone secretion, closely related to weight management
Sleep Stages
A complete sleep cycle is about 90 minutes, including:
- Light sleep: Easy to wake
- Deep sleep: Main recovery phase, body repair occurs
- REM stage (Rapid Eye Movement): Brain is active, dreaming occurs, memory integration
Sleep Duration Recommendations
- Adults: 7-9 hours
- Teenagers: 8-10 hours
- Children: 9-11 hours
Circadian Rhythm: Following the Body’s Natural Rhythm
What Is Circadian Rhythm
Circadian rhythm is the body’s internal clock, controlling sleep-wake cycles, body temperature changes, and hormone secretion. Following circadian rhythm is efficient; fighting it leads to sleep problems.
Importance of Daylight
- Morning light exposure: Activates awakening mode, adjusts biological clock
- Evening light reduction: Avoid light inhibiting melatonin secretion
- Suggestion: At least 30 minutes of outdoor activity daily, especially in the morning
