⏳ Understanding Sleep Cycles & Deep Sleep
Sleep is divided into four key stages, with each cycle lasting 90 minutes. Your body goes through multiple cycles each night, progressing from light sleep to deep sleep and ending in REM sleep.
The best time to wake up for deep sleep aligns with your body’s sleep cycles and can make a significant difference in how you feel.
The Four Stages of Sleep
1️⃣ Stage 1: Light Sleep (1–5 minutes)
- Transition from wakefulness to sleep
- Brain activity slows, and muscles relax
- Easy to wake up from
2️⃣ Stage 2: Deeper Light Sleep (10–25 minutes)
- Body temperature drops, and breathing slows
- Prepares for deep sleep
- Accounts for 50% of total sleep time
3️⃣ Stage 3: Deep Sleep (20–40 minutes)
- Also known as slow-wave sleep (SWS)
- Essential for muscle recovery, immune function, and memory consolidation
- Waking up during this stage causes grogginess and fatigue
4️⃣ Stage 4: REM Sleep (10–60 minutes)
- The dreaming stage, where brain activity increases
- Critical for learning, creativity, and emotional regulation
- REM cycles get longer as the night progresses
To wake up feeling refreshed, you should wake up at the end of a sleep cycle, not in the middle of deep sleep.
