I. Create an Ideal Sleep Environment: A Dark, Quiet & Comfortable Bedroom
Control light: Use blackout curtains to block outside light, choose warm yellow night lights (avoid blue light), or wear an eye mask.
Regulate temperature: The most comfortable sleeping temperature for the human body is 18–22℃. Use breathable bedding in summer and light quilts in winter to avoid overheating or coldness.
Reduce noise: Use earplugs to block constant noise, or play white noise (such as rain or ocean waves) to mask sudden sounds and help your brain relax.
II. Optimize Pre-Sleep Diet: From Sleep-Friendly Foods to Avoid List
Recommended sleep-friendly foods:
Banana: Rich in magnesium and potassium, which relax muscles and regulate neurotransmitters.
Warm milk: Contains tryptophan, which helps produce serotonin and promotes sleepiness.
Oatmeal: High in beta-glucan, stabilizes blood sugar and prevents nighttime hunger or fluctuations that disturb sleep.
Things to avoid 1 hour before bed:
Avoid caffeine (coffee, tea, energy drinks), as its stimulating effect can last 6–8 hours.
Limit alcohol: although it may help you fall asleep faster, it disrupts deep sleep and causes early waking.
III. Build Healthy Pre-Sleep Habits: Replace Phone Scrolling with a Relaxing Ritual
Digital detox: Turn off phones, computers and other electronic devices before bed, or turn on night mode to reduce blue light. Studies show that using electronic devices before bed can delay falling asleep by 1–2 hours.
Gentle relaxing activities:
10-minute mindfulness meditation: Focus on breathing and pull your attention away from distracting thoughts.
Stretching or gentle yoga: such as cat-cow pose and child’s pose to relieve muscle tension and improve blood circulation.
Read a physical book: Choose essays or light non-fiction, avoid intense novels.
IV. Moderate Exercise During the Day: “Recharge” for Sleep, Don’t Overspend
Best exercise time: Do 30 minutes of aerobic exercise (brisk walking, swimming, yoga) in the morning or 3–5 PM. For example, 30 minutes of daily walking can increase deep sleep by 15%.
Avoid before bed: No intense exercise (HIIT, running) within 3 hours before bed, as adrenaline can make it hard to fall asleep. Instead, do light stretching or a short walk one hour before bed.
V. Emotional Management: Give Your Brain a “Pre-Sleep Blank Space”
Pre-sleep emotional journal: Write down daily worries and a gratitude list to “lighten your brain load” and stop overthinking at night.
4-7-8 breathing method: Inhale for 4 seconds, hold for 7 seconds, exhale for 8 seconds. Repeat 3–5 rounds to quickly lower heart rate and blood pressure.
