Overview
- Use a clear document outline: header, nav, main, section, footer.
- Include at least one list and one table.
- Add an accessible figure with a caption.
Sleep Stages (very short)
- N1: very light sleep, easy to wake.
- N2: light sleep; most time is here.
- N3: deep sleep; body recovery.
- REM: vivid dreams; memory support.
Healthy sleep moves through these stages in cycles of about 90 minutes.
Good Sleep Habits
- Keep a regular schedule (go to bed and wake up at the same time).
- Limit late caffeine and heavy meals.
- Keep the room dark, quiet, and cool.
- Put screens away 30–60 minutes before bed.
