Habit | Why It Works | Practical Tip |
Dim the lights | Reduces melatonin suppression | Replace bright overhead lights with warm, dim lamps or night‑light LEDs |
Use “night‑mode” | Keeps screens from emitting blue light | Set devices to “Night Shift” (iOS) or “Night Light” (Android) |
Time | Activity | Goal |
9:30 pm | Disconnect – Turn off screens, lock the phone | Reduce blue‑light exposure |
9:40 pm | Warm shower or bath (38–40 °C) | Increase body temperature, trigger post‑bath cooling that signals sleep |
9:55 pm | Light stretching or gentle yoga | Release muscle tension, activate vagal tone |
10:10 pm | Read a physical book or journal | Mental calmness, cue to wind down |
10:25 pm | Night‑time meditation (4‑4‑8 breathing) | Lower heart rate, increase parasympathetic activity |
10:35 pm | Set the room – cool (18–20 °C), dark, quiet | Create ideal sleep environment |
10:45 pm | Lights out – bed time | Allow melatonin to rise naturally |
Evening Factor | Impact on Sleep | Suggested Practice |
Late‑night snack | Can spike blood sugar and cortisol | If hungry, choose a light, protein‑rich snack (e.g., Greek yogurt) |
Alcohol | Disrupts REM sleep, causes awakenings | Limit to no more than one drink per night, finish 2–3 h before bed |
Caffeine | Increases alertness for 4–6 h | Avoid after 2 pm, consider herbal teas (chamomile, valerian) |
Hydration | Mild dehydration can impair focus and sleep | Drink water or herbal tea (1–2 cups) but taper off 1 h before bed |
